First 'extreme' solar storm in 20 years brings spectacular auroras

The most powerful solar storm in more than two decades struck Earth on Friday, triggering spectacular celestial light shows from Tasmania to Britain -- and threatening possible disruptions to satellites and power grids as it persists into the weekend.

The first of several coronal mass ejections (CMEs) -- expulsions of plasma and magnetic fields from the Sun -- came just after 1600 GMT, according to the National Oceanic and Atmospheric Administration (NOAA)'s Space Weather Prediction Center.

It was later upgraded to an "extreme" geomagnetic storm -- the first since the "Halloween Storms" of October 2003 caused blackouts in Sweden and damaged power infrastructure in South Africa. More CMEs are expected to pummel the planet in the coming days.

Social media lit up with people posting pictures of auroras from northern Europe and Australasia.

"We've just woken the kids to go watch the Northern Lights in the back garden! Clearly visible with the naked eye," Iain Mansfield in Hertford, England, told AFP.

That sense of wonder was shared in Australia's island state of Tasmania.

"Absolutely biblical skies in Tasmania at 4am this morning. I'm leaving today and knew I could not pass up this opportunity," photographer Sean O' Riordan posted on social media platform X alongside a photo.

The excitement spread across Europe and North America, from Mont Saint-Michel on the French coast to Payette, Idaho, where the sky shimmered with green light above the western US states.

Authorities notified satellite operators, airlines and the power grid to take precautionary steps for potential disruptions caused by changes to Earth's magnetic field.

Elon Musk, whose Starlink satellite internet operator has some 5,000 satellites in low Earth orbit, described the solar storm as the "biggest in a long time."

"Starlink satellites are under a lot of pressure, but holding up so far," Musk posted on his X platform.

Unlike solar flares, which travel at the speed of light and reach Earth in around eight minutes, CMEs travel at a more sedate pace, with officials putting the current average at 800 kilometers per second.

The CMEs emanated from a massive sunspot cluster that is 17 times wider than our planet. The Sun is approaching the peak of an 11-year cycle that brings heightened activity.

- 'Go outside tonight and look' -

Mathew Owens, a professor of space physics at the University of Reading, told AFP that how far the effects would be felt over the planet's northern and southern latitudes would depend on the storm's final strength.

"Go outside tonight and look would be my advice because if you see the aurora, it's quite a spectacular thing," he said. People with eclipse glasses can also look for the sunspot cluster during the day.

NOAA's Brent Gordon encouraged the public to try to capture the night sky with phone cameras even if they couldn't see auroras with their naked eyes.

"Just go out your back door and take a picture with the newer cell phones and you'd be amazed at what you see in that picture versus what you see with your eyes."

- Spacecraft and pigeons -

Fluctuating magnetic fields associated with geomagnetic storms induce currents in long wires, including power lines, which can potentially lead to blackouts. Long pipelines can also become electrified, leading to engineering problems.

Spacecraft are also at risk from high doses of radiation, although the atmosphere prevents this from reaching Earth.

NASA has a dedicated team looking into astronaut safety and can ask astronauts on the International Space Station to move to places within the outpost that are better shielded.

Following one particularly strong flare peak, the US Space Weather Prediction Center said users of high-frequency radio signals "may experience temporary degradation or complete loss of signal on much of the sunlit side of Earth."

Even pigeons and other species that have internal biological compasses could be affected. Pigeon handlers have noted a reduction in birds coming home during geomagnetic storms, according to NASA's Jet Propulsion Laboratory.

The most powerful geomagnetic storm in recorded history, known as the Carrington Event after British astronomer Richard Carrington, occurred in September 1859.

Excess currents on telegraph lines at that time caused electrical shocks to technicians and even set some telegraph equipment ablaze.By Issam Ahmed, First 'extreme' solar storm in 20 years brings spectacular auroras

Nuclear's role in reaching climate targets recognised by G7

The meeting of the G7 ministers (Image: G7 Italia)

The Group of Seven (G7) nations have committed to support the use of nuclear energy in those countries that opt to use it, a communique released at the end of the G7 Ministerial Meeting on Climate, Energy and Environment in Turin, Italy, says.

"Those countries that opt to use nuclear energy or support its use recognise its potential as a clean/zero-emissions energy source that can reduce dependence on fossil fuels to address the climate crises and improve global energy security," the document states.

"These countries recognise nuclear energy as a source of baseload power, providing grid stability and flexibility, and optimising use of grid capacity, while countries that do not use nuclear energy or do not support its use prefer other options to achieve the same goals, taking into account their assessment of associated risks and costs of nuclear energy."

The ministers noted the declaration issued by 25 countries during the COP28 climate conference in Dubai in December last year, setting a goal to triple global nuclear generating capacity by 2050. The communique said the ministers "recognise that, for countries that opt to use it, nuclear energy will play a role in reducing dependence on fossil fuels, supporting the transition to net-zero and ensuring energy security, while other countries choose other energy sources to achieve these goals".

The ministers also said that new reactor designs - including advanced and small modular reactors - "could bring in the future additional benefits such as improved safety and sustainability, reduced cost of production, reduced project risk, waste management improvement, better social acceptance, opportunities for industry by providing at the same time energy, high temperature heat, hydrogen".

They committed to support multilateral efforts to strengthen the resilience of nuclear supply chains and to continue the cooperation for building a robust nuclear supply chain in the framework of G7 and of the Nuclear Energy Working Group established in Sapporo.

The ministers noted that G7 leaders remain committed to reducing reliance on civil nuclear-related goods from Russia and the ongoing efforts by countries that operate Russian-designed reactors to make progress in securing alternative nuclear fuel contracts and to reduce dependencies related to spare parts, components and services.

They also said they would promote research and development initiatives on innovative nuclear power technologies "for those countries that opt to use nuclear energy or support its use".

The communique added that the G7 will "promote the responsible deployment of nuclear energy technologies including for advanced and small modular reactors, including microreactors, and work collectively to share national best practices, including for responsible waste management, enable greater access to project financing tools, support sectorial collaboration, designing licensing procedures and strengthening coordination on development of commercial projects among interested G7 members and third markets".

The ministers said: "We underscore the importance for all countries and their respective people of upholding the highest standards of safety, security, and safeguards and non-proliferation, particularly as more countries adopt nuclear power as part of their energy mix."

Speaking at a joint press conference following the ministerial meeting, which he presided over, Italy's Minister of the Environment and Energy Security, Gilberto Pichetto Fratin said: "When it comes to nuclear energy ... our seven countries indicated in the communique that we will proceed together in order to promote further research and ensure that the conditions are in place to promote the use of nuclear energy, which is a clean form of energy."

He added, without naming Germany: "This is something that is not binding. Obviously, we are aware that in the G7 there is a country that currently does not want to pursue the development of nuclear energy."

The ministers' statement came following a call by the nuclear industry for G7 governments to embrace nuclear deployment as a strategic priority, by maximising use of existing nuclear power plants and setting clear plans for further deployment that would fulfil the targets they set at COP28, to triple global nuclear capacity.

The statement was signed by the heads of Associazione Italiana Nucleare, Canadian Nuclear Association, Groupement des Industriels Français de l'Energie Nucléaire (Gifen), Japan Atomic Industrial Forum, Nuclear Energy Institute, Nuclear Industry Association, Nucleareurope and World Nuclear Association.

The G7 is an informal forum that brings together Italy, Canada, France, Germany, Japan, the UK, and the USA. The European Union also participates in the group and is represented at the summits by the President of the European Council and the President of the European Commission.Researched and written by World Nuclear News. Nuclear's role in reaching climate targets recognised by G7 : Nuclear Policies - World Nuclear News

UK and New Zealand partner for subsea cable earthquake

The National Physical Laboratory (NPL), the UK’s National Metrology Institute, has partnered with Measurement Standards Laboratory (MSL) in New Zealand to carry out earthquake detection tests through subsea cables in the Pacific Ocean.

The duo will carry out the tests in a 3,876km-long section of the Southern Cross NEXT cable (a subsea cable that connects Aukland, Sydney and Los Angeles), that sits on the floor of the Tasman Sea between Australia and New Zealand. The area has been chosen as it is highly seismically active –meaning it is vulnerable to earthquakes– which the NPL say is “an ideal test bed for advancing the technology and demonstrating its full potential.”

As part of the trial, scientists will turn the cable section into various sensors for earthquakes and ocean currents, by performing ultra-sensitive optical measurements. It will not need any new hardware or infrastructure, only the cable itself. This technique, which was created NPL in 2021, will mean the cable can gather continuous, real-time environmental data from the ocean floor. This will act as an early warning system for coastal communities in the event of a tsunami. If the trial is successful, the concept could be turned into a worldwide monitoring system.

“This technology, pioneered at NPL, is the perfect example of how our science can create impact, delivering tangible benefits for society which will simultaneously improve our understanding of the world,” said Dr Peter Thompson, CEO of NPL in a press release.

UK Science Minister Andrew Griffith echoed this sentiment, adding that “bringing the UK and New Zealand’s brightest minds together, to overhaul how we give advance warning of tsunamis, could save scores of lives. This work proves the value of breakthrough technologies like quantum, as well as the international teamwork that’s crucial to harnessing them.

Heat from El Niño can warm oceans off West Antarctica – and melt floating ice shelves from below

AndreAnita/Shutterstock Maurice Huguenin, UNSW Sydney; Matthew England, UNSW Sydney, and Paul Spence, University of Tasmania

As snow falls on Antarctica, layers build up and turn to ice. Over time, this compressed snow has become a continent-sized glacier, or ice sheet. It’s enormous – almost double the size of Australia and far larger than the continental United States.

As the weight of ice builds up, the ice sheet begins to move towards the oceans. When it reaches the sea, the ice floats. These floating extensions are known as ice shelves. The largest is over 800 kilometres wide.

When the ocean water has a temperature close to 0°C, these ice shelves can persist for a long time. But when temperatures rise, even a little, the ice melts from below. Antarctic ice shelves are now losing an alarming 150 billion tons of ice per year, adding more water to the ocean and accelerating global sea level rise by 0.6 mm per year. Ice shelves in West Antarctica are particularly prone to melting from the ocean, as many are close to water masses above 0°C.

While the melting trend is clear and concerning, the amount can vary substantially from year-to-year due to the impact of both natural climate fluctuations and human-made climate change. To figure out what is going on and to prepare for the future, we need to tease apart the different drivers – especially El Niño-Southern Oscillation, the world’s largest year-to-year natural climate driver.

Our new research explores how heat brought by El Niño can warm the ocean around West Antarctica and increase melting of the ice shelves from below.

How can El Niño-Southern Oscillation affect Antarctica?

Australians are very familiar with the two phases of this climate driver, El Niño and La Niña, as they tend to bring us hotter, dryer weather and cooler, wetter weather, respectively. But the influence of this cycle is much larger, affecting weather and climate all around the Pacific.

Can it reach through Antarctica’s cold, fast currents of air and water? Yes.

Giant convective thunderstorms in the Pacific’s equatorial regions move east during El Niño and intensify in the West during La Niña. As these storm systems change, they excite ripples in the atmosphere that are able to travel large distances, just as waves can cross oceans. Within two months, these atmospheric waves reach the Antarctic continent, where their energy can affect the coastal atmosphere and ocean circulation. During El Niño, the energy from these waves weakens the easterly winds off West Antarctica (and vice versa for La Niña).

Using satellite data, researchers recently found that West Antarctic ice shelves actually gain height but lose mass during El Niño. That’s because more low-density snow falls at the top of the ice shelves, while at the same time more warm water flows under the ice shelves where it melts compressed high-density ice from underneath.

What we don’t yet know is how this warmer water (above zero) comes up from below. Similarly, we don’t know what happens during La Niña.

Answering these questions with the few observations we have from Antarctica is challenging because this climate driver doesn’t happen in isolation. Storms, tides, large eddy currents and other climate drivers such as the Southern Annual Mode can change the temperatures of the water under ice shelves too, and they can occur at the same time as El Niño.

Finding a needle in the ice stack

So how did we do it? Modelling.

We take a high-resolution global ocean circulation model and added El Niño and La Niña events to the baseline simulation. By doing so, we can examine what these anomalies do to the currents and temperatures around Antarctica.

The energy brought by El Niño’s atmospheric waves to West Antarctica weakens the prevailing easterly winds along the coasts.

Normally, most of the warm water reservoir is located off the continental shelf rather than on the continental shelf. As the winds weaken, more of this warmer water – known as Circumpolar Deep Water – is able to flow onto the continental shelf and near the base of the floating ice shelves.

During El Niño, weaker winds along the coasts push less cold Antarctic surface waters towards the continent, allowing warmer Circumpolar Deep Water to flow to the base of the ice shelves. During La Niña, stronger winds drive a wedge of cold water up towards the continent, reducing the inflow of warm water. Maurice Huguenin, CC BY-SA

We call this water mass “warm”, but that’s relative – it’s only 1–2°C above freezing, and the heat only warms the water on the continental shelf by about 0.5°C. But that’s enough to begin melting ice shelves, which are at or below freezing point.

As you’d expect, the longer the warm water stays on the shelf and the hotter it is, the more melting occurs.

During La Niña, the opposite occurs and the ice rebounds. Winds along the coast strengthen, pushing more cold surface water onto the continental shelf and preventing warm water from flowing under the ice shelves.

What does this mean for the near future?

Researchers have found El Niño and La Niña have already become more frequent and more extreme.

If this trend continues, as climate projections suggest, we can expect warming around West Antarctica to get even stronger during El Niño events, accelerating ice shelf melting and speeding up sea level rise.

More frequent and stronger El Niño events could also push us closer to a tipping point in the West Antarctic ice sheet, after which accelerated melting and mass loss could become self-perpetuating. That means the ice wouldn’t melt and reform but begin to steadily melt.

More bad news? Unfortunately, yes. The only way to stop the worst from happening is to get to net zero carbon emissions as quickly as humanly possible.

How global warming is reshaping winter life in Canada

H. Damon Matthews, Concordia University and Mitchell Dickau, Concordia University As we begin to emerge out of yet another mild winter, Canadians are once again being reminded of just how acutely global warming has changed Canada’s winter climate.

The impacts of this mild winter were felt across the country and touched all aspects of winter culture. From melting ice castles at Québec’s winter carnival, to a dismal lack of snow at many Western Canada ski resorts, seemingly no part of Canada was unaffected. But the change that will likely be felt most keenly by many Canadians is the loss of a reliable outdoor skating season.

For the second year running, Ottawa’s Rideau Canal Skateway was closed for what should be the peak of the skating season. In 2022-2023, the Skateway did not open at all for the first time ever. This winter, a portion of the Skateway opened briefly in January, but continuing mild temperatures forced a closure again after only four days of skating. In Montréal, fewer than 40 per cent of the city’s outdoor rinks were open in the middle of February.

There is no obvious upside to this story. Outdoor skating in Canada is fast becoming the latest casualty of our failure to confront the reality of the climate crisis.

On thin ice

More than a decade ago, our research group published our first analysis of how outdoor skating was being affected by warming winter temperatures in Canada. We showed that even as of 2005, there was already evidence of later start dates, and shorter skating seasons across most of the country.

A report on the management of the Rideau Canal Skateway in 2023, produced by the CBC.

These conclusions were echoed by subsequent publications from the RinkWatch project, which has reported consistent declines in skating season length and quality in many Canadian cities.

Meanwhile in Ottawa, skating days on the Rideau Canal Skateway have been trending downwards over the last 20 years. In this time, the typical skating season has decreased by almost 40 per cent, a trend that is clearly correlated with increasing winter temperatures over the same period.

Moving in the wrong direction

Climate mitigation progress continues to be far too slow.

Global CO2 emissions reached their highest level ever recorded in 2023, and average global temperatures have now reached 1.3 C above pre-industrial temperatures. If these trends continue, we are on track to reach 1.5 C — the lower threshold of the Paris Agreement temperature target — in less than seven years.

In our 2012 paper, we estimated that suitable rink flooding days could disappear across most of southern Canada by mid-century. In a more recent analysis of Montréal’s outdoor rinks, we estimated that the number of viable skating days in Montréal could decrease to zero by as early as 2070.

In hindsight, these and other similar projections may have been far too optimistic. In a study of Rideau canal skating days published in 2015, the authors projected declining but sustained skating conditions throughout this century, even in a high future emissions scenario. The reality of the past two seasons shows that skating conditions have deteriorated far more quickly than predicted.

Global temperatures in 2023 were the highest ever recorded, as were winter temperatures in December 2023 and January 2024. Since 1950, winter temperatures in Canada have increased by more than 3 C, which is about three times the rate of global warming over this same period.

Outdoor rinks require at least three consecutive very cold days to establish a foundation of ice, followed by enough cold days to maintain a good ice surface. Temperatures above freezing are poorly tolerated by outdoor rinks, and rain is often disastrous.

A few degrees of warming in January and February temperatures can be the difference between a rink that is skatable and one that is not. As winters continue to warm, the case for building and maintaining outdoor municipal rinks will become harder to justify.

A stark and still changing new reality

As years go by without any real progress on climate mitigation, it is becoming increasingly difficult to imagine a future in which outdoor rinks will be widely available without artificial refrigeration. Other winter activities will also be affected by changing snow conditions, but outdoor skating will likely be hit first in direct response to warming winter temperatures.

Wayne Gretzky famously learned to skate and play hockey in Branford, Ont. in the 1960s on an outdoor rink built by his father. Reliable winter skating conditions in southern Ontario are already mostly a thing of the past, and are becoming more and more scarce as global warming progresses. It is increasingly unlikely that current and future generations will be able to follow Gretzky’s path.

This reality is both a tragic injustice for many young Canadians and an existential threat to a core aspect of the Canadian winter identity.

Preserving what remains of Canada’s winter skating culture will require that we rapidly step up our efforts to drive down CO2 emissions and stabilize global temperatures. Otherwise, Joni Mitchell’s “river I could skate away on” will become an increasingly wishful dream that soon will exist only in the lyrics of old songs.

Volcano on uninhabited Galapagos island spews lava

ECUADOR - A volcano on an uninhabited island of Ecuador's famous Galapagos archipelago is spewing lava, authorities said Sunday, potentially threatening an array of unique animal species. The La Cumbre volcano on the island of Fernandina blew its top late Saturday, the South American country's Geophysical Institute said. La Cumbre, which stands 1,463 meters (4,799 feet) high, has erupted three times previously since 2017. The Galapagos archipelago, some 1,000 kilometers (600 miles) off the mainland of Ecuador, has flora and fauna found nowhere else in the world. Observing its wonders led British scientist Charles Darwin to develop his ground-breaking theory of evolution by natural selection in the 19th century. La Cumbre has the highest eruption rate of all volcanos in the archipelago, which is a favorite with tourists. Fernandina, with no hotels or restaurants, can only be accessed for short visits from a cruise

boat. The Institute said La Cumbre blew a gas cloud about three kilometers into the air, dispersed by the wind without passing over other islands with human settlements such as neighboring Isabela. It said the duration of the eruption cannot be predicted, nor whether the lava will reach the shore, but data on the volcano's activity suggested this one was likely to be greater than those in 2017, 2018 and 2020. The Institute advised tourists to stay away if any lava does enter the sea.sp/nn/mlr/mdl. Volcano on uninhabited Galapagos island spews lava

Luminous ‘mother-of-pearl’ clouds explain why climate models miss so much Arctic and Antarctic warming

Katrin Meissner, UNSW Sydney; Deepashree Dutta, University of Cambridge, and Martin Jucker, UNSW Sydney

Our planet has warmed by about 1.2°C since 1850. But this warming is not uniform. Warming at the poles, especially the Arctic, has been three to four times faster than the rest of the globe. It’s a phenomenon known as “polar amplification”.

Climate models simulate this effect, but when tested against the past 40 years of warming, these models fall short. The situation is even worse when it comes to modelling past climates with very high levels of greenhouse gases.

This is a problem because these are the same models used to project into the future and forecast how the climate will change. They are likely to underestimate what will happen later this century, including risks such as ice sheet melting or permafrost thawing.

In our new research published today in Nature Geoscience we used a high-resolution model of the atmosphere that includes the stratosphere. We found a special type of cloud appears over polar regions when greenhouse gas concentrations are very high. The role of this type of cloud has been overlooked so far. This is one of the reasons why our models are too cold at the poles.

Back to the future

Looking into past climates can give us glimpses of possible futures for a range of extreme conditions. For us, this means we can use Earth’s history to find out how well our climate models perform. We can test our models by simulating episodes in the past when Earth was much warmer. The advantage of this is that we have temperature reconstructions for these episodes to evaluate the models, as opposed to the future, for which measurements are not available.

If we go back 50 million years or so, our planet was very hot. Carbon dioxide (CO₂) concentrations ranged between 900 and 1,900 parts per million (ppm), compared with 415 ppm today. Methane (CH₄) concentrations were likely also much higher.

Canada’s arctic archipelago was covered in lush rainforests inhabited by alligators, turtles, lizards and mammals.

For these plants and animals to survive, conditions must have been warm and ice-free year-round. Indeed, surface ocean temperatures exceeded 20°C near the north pole (at about 87°N) and 25°C in the Southern Ocean (at about 67°S).

This period called the early Eocene is a perfect test bed for our models, because it was globally very warm, and the poles were even warmer, meaning it was a climate with extreme polar amplification. In addition, the Eocene is recent enough for temperature reconstructions to be available.

But as it turns out, the models fail again. They are much too cold at high latitudes. What are our models missing?

Polar stratospheric clouds

In 1992 American paleoclimatologist Lisa Sloan suggested polar stratospheric clouds might have caused extreme warming at high latitudes in the past.

These clouds are a rare and beautiful sight today. They are also called nacreous or mother-of-pearl clouds for their vivid and sometimes luminous colours.

They form at very high altitudes (in the stratosphere) and at very low temperatures (over the poles). In the present day climate, they appear mainly over Antarctica, but have also been observed during winter months over Scotland, Scandinavia and Alaska, at times when the stratosphere was particularly cold.

Just like greenhouse gases, they absorb infrared radiation emitted by the Earth’s surface and re-emit a portion of this energy back to the surface. This suggests polar stratospheric clouds could be one of the missing puzzle pieces.

They warm the surface. And their effect could be significant, especially in winter, when the sun does not rise. But they are difficult to simulate in a climate model, so most models ignore them. This omission could explain why climate models miss some of the polar warming, because they miss a process that warms the poles.

Three decades after Sloan’s paper, a few atmosphere models are finally complex enough to allow us to test her hypothesis. In our research we use one of them and find that under certain conditions, the additional warming due to these polar stratospheric clouds exceeds 7°C during the winter months. This significantly reduces the gap between climate models and temperature evidence from the early Eocene. Sloan was right.

Implications for future projections

Our research explains why climate models don’t work so well for past climates when greenhouse gas levels were much higher than they are today. But what about the future? Should we be concerned?

There is some good news. While polar stratospheric clouds do warm the poles, they won’t be as common in the future as they were in the distant past, even if both CO₂ and CH₄ reach very high levels.

This is due to another difference between the Eocene and today: the position of continents and mountains, which were different back then and which also influence the formation of polar stratospheric clouds. So even if we hit early Eocene levels of CH₄ and CO₂ in the future, we would expect less polar stratospheric cloud to be formed. This suggests the standard climate models are better at predicting the future than the past.

It’s therefore unlikely the Arctic and Antarctica will be covered by these beautiful clouds anytime soon. But our research shows evidence from past climates can reveal processes that only become important when greenhouse gas concentrations are high. Some of these processes are not included in our models because models are tested against present day observations and other processes simply seemed more important to include. Looking into the past is a way of broadening our horizon and learning for the future.

Polar bears may struggle to produce milk for their cubs as climate change melts sea ice

During their time onshore, polar bear mothers may risk their survival by continuing to nurse when food is not available. (Shutterstock) Louise Archer, University of Toronto

When sea ice melts, polar bears must move onto land for several months without access to food. This fasting period is challenging for all bears, but particularly for polar bear mothers who are nursing cubs.

Our research, published in Marine Ecology Progress Series, found that polar bear lactation is negatively affected by increased time spent on land when sea ice melts.

Impaired lactation has likely played a role in the recent decline of several polar bear populations. This research also indicates how polar bear families might be impacted in the future by continued sea-ice loss caused by climate warming.

Challenges of rearing cubs

While sea ice might appear as a vast and perhaps vacant ecosystem, the frozen Arctic waters provide an essential platform for polar bears to hunt energy-rich seals — the bread and butter of their diet.

Sea ice is a dynamic environment that can vary through time and in different regions of the Arctic. Polar bears in Canada’s western Hudson Bay area experience seasonal sea ice, which melts in the warmer summer months, forcing the polar bears to move onto land until cooler winter temperatures cause the sea ice to refreeze.

On shore, polar bears often remain in a fasting state, using their body stores of fat for fuel. (Shutterstock)

While on shore, hunting opportunities are rare and polar bears generally spend their time in a fasting state. Polar bears rely on their immense body fat stores to fuel them during these leaner months, with some individuals measuring almost 50 per cent body fat when they come onshore in early summer.

While on land, polar bears can lose around a kilogram of body mass per day, so making it to the end of the ice-free season requires them to carefully manage their energy. For most polar bears, this means reducing activity levels and conserving energy until the sea ice returns and seal hunting can resume.

Females with cubs must also factor in the additional burden of lactation. Polar bears produce high-energy milk, which — at up to 35 per cent fat — is like whipping cream. This high-fat milk allows cubs to grow quickly, increasing from just 600 grams at birth to well over 100 kilograms by the time they are around two-and-a-half years old and leave their mothers to become independent.

During the onshore fasting period, polar bear mothers face a difficult trade-off: Stop lactating and risk the health of her growing cubs or continue nursing and risk her own survival as her energy reserves are depleted.

Moderating lactation

Although lactation is important to both mothers and cubs, studies on polar bear lactation are relatively rare.

To better understand how females manage their lactation investment, our research team revisited a data set of polar bear milk samples collected in the late 1980s and early 1990s from polar bears on land during the ice-free period.

We estimated how long each polar bear mom had been fasting based on annual sea-ice breakup dates and found that the energy content of their milk declined the more days spent onshore. Some bears had stopped producing milk entirely. Both milk energy content and lactation probability were negatively related to the mother’s body condition, meaning females in poor body condition had to prioritize their own energetic needs over their cubs.

The bears who reduced their investment in lactation benefited by using up less of their body reserves, meaning they could fast for longer. Yet the cubs who received lower energy milk grew more slowly than offspring of females that maintained their lactation effort. In the long term, this may reduce cub survival and, ultimately, negatively affect population dynamics.

Climate change and population declines

After around three months on land, the probability of a female with cubs lactating was 53 per cent. This dropped to 35 per cent for a female with yearlings (older cubs from the previous year).

The data in our study were collected around three decades ago. Since then, climate warming has meant that the ice-free season in western Hudson Bay has been extending by around seven days per decade. Polar bears are now regularly forced to spend more than four months on land.

As the ice-free season has increased and polar bears must go for longer without food, their average body condition has declined. The ability of female polar bears to nurse their cubs has probably also become increasingly impaired.

This may have contributed to the 50 per cent decline in the population size of the western Hudson Bay population over the last four decades, and is likely to contribute to further declines if climate warming and sea-ice declines continue as projected without mitigation.

This research adds another piece to our understanding of polar bear resilience to climate change. Without action to halt climate warming and sea-ice loss, survival of cubs will be at risk across the Arctic.

We are poised to pass 1.5℃ of global warming – world leaders offer 4 ways to manage this dangerous time

Marcus E Jones, Shutterstock Jonathan Symons, Macquarie University

For three decades, the goal of international climate negotiations has been to avoid “dangerous” warming above 1.5℃. With warming to date standing at around 1.2℃, we haven’t quite reached the zone we labelled dangerous and pledged to avoid.

But recent scientific assessments suggest we’re on the brink of passing that milestone. Within this decade, global annual temperatures will likely exceed 1.5°C above the pre-industrial average for at least one year. This threshold was already briefly passed for the month of July 2023 during the Northern summer. The question is, how do we manage this period of “overshoot” and bring temperatures back down? The goal will be to restore a more habitable climate, as fast as possible. Today an independent group of global leaders released a major report. The Climate Overshoot Commission offers guidance at this crucial time. So far the report’s call for an immediate moratorium on “solar radiation management” (deflecting the sun’s rays to reduce warming) has attracted the most attention. But the details of other recommendations deserve closer inspection.  How can we respond to climate overshoot? Historically, climate policies have focused on mitigation (reducing greenhouse gas emissions). More recently, adaptation has gained prominence. But the climate overshoot report identifies at least four different kinds of responses to warming above 1.5℃, 

• 1. cut emissions to mitigate warming
• 2. adapt to the changing climate 
• 4. remove carbon that is already in the atmosphere or ocean, 
• 5. explore intervening to limit warming by intentionally reflecting a fraction of sunlight into space. 

The commission’s task was to examine how all possible responses might best be combined. Their report was written by 12 global leaders – including former presidents of Niger, Kiribati and Mexico – who worked alongside a youth panel and a team of scientific advisers. The four-step plan to reining in warming Not surprisingly, the commission argues our central task is mitigation. Transitioning away from fossil fuels remains the first priority. But reaching net zero emissions is just the first step. The commission argues developed countries like Australia should go further and aim for net-negative emissions. Why net-negative? In the short term, drawing down carbon can create space for the least industrialised countries to fight poverty while transitioning to clean energy. In the longer term, the whole global economy must achieve net-negative emissions if the planet is to return to our current “safe” climatic zone. The second step is adaptation. Only a few decades ago former United States Vice President Al Gore branded adapting to climate change a “lazy cop-out”. Today we have no choice but to adapt to changing conditions. However, adaptation is expensive – whether it is developing new crop varieties or rebuilding coastal infrastructure. Since the poorest communities who are most vulnerable to climate harms have the least capacity to adapt, the commission recommends international assistance for locally controlled, context-specific strategies. As a third step, the commission agrees with scientific assessments that carbon dioxide “will need to be removed from the air on a significant scale and stored securely” if we are to avoid permanent overshoot beyond 1.5℃ warming. But how to achieve large-scale permanent, carbon removal? Some environmental activists support natural solutions such as planting trees but oppose industrial methods that seek to store carbon in inorganic form such as carbon capture and storage underground. The commission agrees the organic/inorganic distinction is important. However, it points out while forests bring many benefits, carbon stored in ecosystems is often re-released – for example, in forest fires. The commission worries many carbon removal approaches are phoney, impermanent or have adverse social and environmental impacts. However, instead of ruling out technologies on ideological grounds, it recommends research and regulation to ensure only socially beneficial and high-integrity forms of carbon removal are scaled up. The fourth step – “solar radiation management” – refers to techniques that aim to reduce climate harms caused by reflecting some of the Sun’s energy into space. No-one likes the idea of solar radiation management. But no-one likes getting vaccinated either – our gut reactions don’t provide a fool-proof guide to whether an intervention is a worth considering. Should we trust our guts on this one? While climate models suggest solar radiation management could reduce climate harms, we don’t yet properly understand associated risks. The commission approaches this topic with caution. On the one hand, it recommends an immediate “moratorium on the deployment of solar radiation modification and large-scale outdoor experiments” and rejects the idea that deployment is now inevitable. On the other hand, it recommends increased support for research, international dialogue on governance, and periodic global scientific reviews. Time to examine intervention in the climate system? The idea we can avoid dangerous warming completely seems increasingly quaint. Like baggy jeans, the boy band NSYNC and the iPod shuffle, it reminds us of a more innocent era. Yet, Australia’s climate debate often seems stuck in this era. The widespread hope we “still have time” means we are not yet discussing the merits of more interventionist responses to the climate crisis. However, there’s increasing reason to be sceptical incremental measures will be sufficient. We may soon be forced to move beyond the non-interventionist, conservation paradigm. Whether or not its recommendations are taken up, the Climate Overshoot Commission’s work shows how the international community has failed to avert dangerous climate change. Reckoning with the consequences of this failure will dominate public policy for decades to come. This new report takes us a step forward. Jonathan Symons, Senior Lecturer, Macquarie School of Social Sciences, Macquarie University This article is republished from The Conversation under a Creative Commons license.

Earthquake footage shows Turkey’s buildings collapsing like pancakes. An expert explains why

 

Mustafa Karali / AP Mark Quigley, The University of Melbourne

A pair of huge earthquakes have struck in Turkey, leaving more than 3,000 people dead and unknown numbers injured or displaced.

The first quake, near Gaziantep close to the Syrian border, measured 7.8 in magnitude and was felt as far away as the UK. The second occurred nine hours later, on what appears to be an intersecting fault, registering a magnitude of 7.5.

Adding to the devastation, some 3,450 buildings have collapsed, according to the Turkish government. Many of the modern buildings have failed in a “pancake mode” of structural collapse.

Why did this happen? Was it simply the enormous magnitude and violence of the quake, or is the problem with the buildings?

Thousands of years of earthquakes

Earthquakes are common in Turkey, which sits in a very seismically active region where three tectonic plates constantly grind against one another beneath Earth’s surface. Historical records of earthquakes in the region go back at least 2,000 years, to a quake in 17 CE that levelled a dozen towns.

The East Anatolian Fault zone that hosted these earthquakes is at the boundary between the Arabian and Anatolian tectonic plates, which move past each other at approximately 6 to 10 mm per year. The elastic strain that accumulates in this plate boundary zone is released by intermittent earthquakes, which have occurred for millions of years. The recent earthquakes are thus not a surprise.

Despite this well-known seismic hazard, the region contains a lot of vulnerable infrastructure.

Over the past 2,000 years we have learnt a lot about how to construct buildings that can withstand the shaking from even severe earthquakes. However, in reality, there are many factors that influence building construction practices in this region and others worldwide.

Poor construction is a known problem

Many of the collapsed buildings appear to have been built from concrete without adequate seismic reinforcement. Seismic building codes in this region suggest these buildings should be able to sustain strong earthquakes (where the ground accelerates by 30% to 40% of the normal gravity) without incurring this type of complete failure.

The 7.8 and 7.5 earthquakes appear to have caused shaking in the range of 20 to 50% of gravity. A proportion of these buildings thus failed at shaking intensities lower than the “design code”.

There are well-known problems in Turkey and elsewhere with ensuring safe building construction and adherence to seismic building codes. Similar building collapses have been seen in past earthquakes in Turkey.   

A known problem: a collapsed apartment building after the 1999 earthquake in Izmit, Turkey. Hurriyet / AP

In 1999, a huge quake near Izmit saw some 17,000 people dead and as many as 20,000 buildings collapse.

After a quake in 2011 in which hundreds of people died, Turkey’s then prime minister, Recep Tayyip Erdogan, blamed shoddy construction for the high death toll, saying: “Municipalities, constructors and supervisors should now see that their negligence amounts to murder.”

Reconstruction

Even though Turkish authorities know many buildings are unsafe in earthquakes, it is still a difficult problem to solve. Many of the buildings are already built, and seismic retrofitting may be expensive or not considered a priority compared to other socio-economic challenges.

However, reconstruction after the quake may present an opportunity to rebuild more safely. In 2019, Turkey adopted new regulations to ensure buildings are better equipped to handle shaking.

While the new rules are welcome, it remains to be seen whether they will lead to genuine improvements in building quality.

In addition to substantive loss of life and infrastructure damage, both earthquakes are likely to have caused a myriad of environmental effects, such as ruptured ground surfaces, liquified soil, and landslides. These effects may render many areas unsafe to rebuild on – so reconstruction efforts should also include planning decisions about what can be built where, to lower future risks.

For now, aftershocks continue to shake the region, and search and rescue efforts continue. Once the dust settles, reconstruction will begin – but will we see stronger buildings, able to withstand the next quake, or more of the same?

Indian outfit wins UN award for efforts to combat climate change amid COVID-19

SPORTS LIFESTYLE ENTERTAINMENT SPECIALS FEEDS UPCLOSE GALLERY CITIZEN REPORTER DOGRI CORNER Home World Indian outfit wins UN award for efforts to combat climate change amid COVID-19 OCT 28, 2020 UNITED NATIONS: An Indian organisation that leverages tourism and technology to help remote communities access solar energy has won a prestigious UN award for its efforts to combat climate change amid the Covid-19 pandemic. The Global Himalayan Expedition (GHE) is among the winners of the 2020 UN Global Climate Action Award. GHE is one of the world's first organisations using tourism and technology to bring solar energy to remote communities. The recipients of the 2020 United Nations Global Climate Action Awards, announced Tuesday, bring focus to the best examples of what people across the globe are doing "to combat climate change in a year that has cast darkness upon so many." According to a statement on the United Nations Framework Convention on Climate Change (UNFCCC) website, GHE is the one of the world's first outfit using tourism and technology to bring solar energy to remote communities as recognised by the World Travel and Tourism Council (WTTC) and the United Nations World Tourism Organisation (UNWTO). In the Hindu Kush Region, there are more than 16 million people without access to basic energy mainly due to their geographic remoteness. GHE conducts "Impact Expeditions" to remote Himalayan villages and uses a portion of the expedition fee to fund the capital cost of the hardware, transportation, installation and training of village-scale solar micro-grids. The micro-grid infrastructure set up by GHE is owned and operated by the community. To date, the GHE has solar electrified more than 131 villages in three regions of India, directly impacting the lives of more than 60,000 villagers. More than 1,300 travellers from 60 different countries have been a part of these expeditions. Enabling livelihood through homestay tourism has generated over USD 114,000 in income for the villages, which represents a 45 per cent increase in the annual household income, the statement said. UNFCCC said this year's award-winning projects demonstrate leadership on climate change by nations, businesses, investors, cities, regions and civil societies as a whole. They range from the Caribbean's only carbon-neutral hotel to the world's first platform fully dedicated to green bonds to the first all-women solar team in Lebanon. Congratulating the winners of the 2020 UN Global Climate Action Awards, UN Secretary-General António Guterres said the winners provide tangible proof that climate action is underway around the world. "It is exciting to see these climate solutions, which reinforce my call for decisive leadership on climate change by governments, businesses and cities, and for a green recovery from the Covid-19 pandemic. Let us keep pressing ahead to build a more sustainable and equitable future for all," he said. UN Climate Change Executive Secretary Patricia Espinosa said the last eight months have been a nightmare for many throughout the world. "Covid-19 has altered lives, economies and the nature of business on every continent -- from the largest cities to the smallest villages. It is the most urgent threat facing humanity today, but we cannot forget that climate change is the biggest threat facing humanity over the long term," said Espinosa. Espinosa said the convergence of these two crises has opened a window of opportunity to build forward, to build cities and communities that are safe, healthy, green and sustainable. "Nothing exemplifies this better than the efforts of our 2020 award-winning activities to address climate change." The award announcement is part of the wider effort to mobilise action and ambition as national governments work toward implementing the Paris Climate Change Agreement and the Sustainable Development Goals. The UN Global Climate Action Awards are spearheaded by the Momentum for Change initiative at UN Climate Change. The projects are recognised as innovative solutions that not only address climate change but also help drive progress on many other sustainable development goals. The 2020 winning activities were selected by an international advisory panel as part of the UN Climate Change's Momentum for Change initiative. "It is crucial we celebrate all actors who are leading the way," said Gabrielle Ginér, Chair of the Advisory Panel. "The recipients of the UN Global Climate Action Awards send a strong political signal to all nations, and through their leadership and creativity, we see essential change."

Young Indian activist named by UN chief to new advisory group on climate change

JUL 28, 2020 UNITED NATIONS: A climate activist from India has been named by UN Secretary-General Antonio Guterres to his new advisory group comprising young leaders who will provide perspectives and solutions to tackle the worsening climate crisis, as the global body mobilizes action as part of the COVID-19 recovery efforts. Archana Soreng joins six other young climate leaders from around the world who have been named by Guterres to his new Youth Advisory Group on Climate Change. Soreng is "experienced in advocacy and research, and she is working to document, preserve, and promote traditional knowledge and cultural practices of indigenous communities," the UN said in a statement on Monday. "Our ancestors have been protecting the forest and nature over the ages through their traditional knowledge and practices. Now it is on us to be the front runners in combating the climate crisis," said Soreng, who has studied regulatory governance from the Tata Institute of Social Sciences (TISS) Mumbai and is the former TISS Students Union President. The young activists, aged between 18 and 28 years, will advise the UN chief regularly on accelerating global action and ambition to tackle the worsening climate crisis. The announcement marks a new effort by the United Nations to bring more young leaders into decision-making and planning processes, as the UN works to mobilize climate action as part of the COVID-19 recovery efforts. "We are in a climate emergency. We do not have the luxury of time," Guterres said in a video announcing the establishment of the advisory group. "We need urgent action now - to recover better from COVID-19, to confront injustice and inequality and address climate disruption," he said. Guterres said young people are on the front lines of climate action, showing nations and leaders what bold leadership looks like. "That is why I am launching my Youth Advisory Group on climate change today - to provide perspectives, ideas and solutions that will help us scale up climate action," the UN chief said. The members of the Secretary-General's Youth Advisory Group on Climate Change represent the diverse voices of young people from all regions as well as small island states. They will offer perspectives and solutions on climate change, from science to community mobilization, from entrepreneurship to politics, and from industry to conservation, the UN said. The initial seven members of the group have been chosen to give frank and fearless advice to the Secretary-General, at a time of growing urgency to hold government and corporate leaders to account on climate action. The other selected members of the group are climate activist Nisreen Elsaim of Sudan, Fiji's Ernest Gibson, the co-coordinator for 350 Fiji, a regional youth-led climate change network, young economist Vladislav Kaim of Moldova who is committed to ensuring green and decent jobs for youth. Sophia Kianni of the United States who has helped organise nationwide strikes and is the founder of international nonprofit Climate Cardinals, founder and coordinator of Generation Climate Europe and spokesperson for Youth and Environment Europe, Nathan Metenier of France and lawyer and human rights defender Paloma Costa of Brazil. The establishment of the group builds on last year''s successful Youth Climate Summit - the first time a Secretary-General has convened a summit for young people entirely devoted to climate action. The summit brought over 1,000 young climate champions together from more than 140 countries to share their solutions on the global stage and deliver a clear message to world leaders: we must act now to confront the climate crisis. The initiative is also aligned with the Secretary-General''s vision for the UN Youth Strategy, launched in September 2018. Copyright © Jammu Links News, Source: Jammu Links News

Nuclear energy too expensive, too slow to battle climate change: report

Nuclear power as a renewable power option is more expensive and slower to implement than alternatives and therefore is not effective in the effort to battle the climate emergency, rather it is counterproductive, as the funds are then not available for more effective options, says a report on the status and trends of the international nuclear industry.

While the number of operating nuclear reactors has increased globally over the past year by four to 417 as of mid-2019, it remains significantly below historic peak of 438 in 2002, according to the World Nuclear Industry Status Report 2019 (WNISR2019), which is being released at the Central European University (CEU) in Budapest. Nuclear construction has been shrinking over the past five years with 46 units underway as of mid-2019, compared to 68 reactors in 2013 and 234 in 1979. The number of annual construction starts has fallen from 15 in the pre-Fukushima year (2010) to five in 2018 and, so far, one in 2019. The historic peak was in 1976 with 44 construction starts, more than the total in the past seven years. WNISR project coordinator and publisher Mycle Schneider stated: “There can be no doubt: the renewal rate of nuclear power plants is too slow to guarantee the survival of the technology. The world is experiencing an undeclared ‘organic’ nuclear phaseout.” Consequently, as of mid-2019, for the first time the average age of the world nuclear reactor fleet exceeds 30 years. However, renewables continue to outpace nuclear power in virtually all categories. A record 165 gigawatts (GW) of renewables were added to the world’s power grids in 2018; the nuclear operating capacity increased by 9 GW. Globally, wind power output grew by 29 per cent in 2018, solar by 13 per cent, nuclear by 2.4 per cent. Compared to a decade ago, nonhydro renewables generated over 1,900 TWh more power, exceeding coal and natural gas, while nuclear produced less. What does all this mean for the potential role of nuclear power to combat climate change? WNISR2019 provides a new focus chapter on the question. Diana Ürge-Vorsatz, Professor at the Central European University and Vice-Chair of the Intergovernmental Panel on Climate Change (IPCC) Working Group III, notes in her Foreword to WNISR2019 that several IPCC scenarios that reach the 1.5°C temperature target rely heavily on nuclear power and that “these scenarios raise the question whether the nuclear industry will actually be able to deliver the magnitude of new power that is required in these scenarios in a cost-effective and timely manner. This report is perhaps the most relevant publication to answer this pertinent question.” Over the past decade, levelised cost estimates for utility-scale solar dropped by 88 per cent, wind by 69 per cent, while nuclear increased by 23 per cent. New solar plants can compete with existing coal fired plants in India, wind turbines alone generate more electricity than nuclear reactors in India and China. But new nuclear plants are also much slower to build than all other options, eg, the nine reactors started up in 2018 took an average of 10.9 years to be completed. In other words, nuclear power is an option that is more expensive and slower to implement than alternatives and therefore is not effective in the effort to battle the climate emergency, rather it is counterproductive, as the funds are then not available for more effective options. The rather surprising outcome of the analyses is that even the extended operation of existing reactors is not climate effective as operating costs exceed the costs of competing energy efficiency and new renewable energy options and therefore durably block their implementation. “You can spend a dollar, a euro, a forint or a ruble only once: the climate emergency requires that investment decisions must favor the cheapest and fastest response strategies. The nuclear power option has consistently turned out the most expensive and the slowest,” Mycle Schneider concludes. The WNISR2019 assesses in 323 pages the status and trends of the international nuclear industry and analyses the potential role of nuclear power as an option to combat climate change. Eight interdisciplinary experts from six countries, including four university professors and the Rocky Mountain Institute’s co-founder and chairman emeritus, have contributed to the report.Source: https://www.domain-b.com

World's second largest rainforest at risk from lifting of logging moratorium

New licences could soon be issued to logging companies in the Democratic Republic of Congo (DRC), threatening to accelerate the rate of deforestation in the region.

A tropical rainforest more than twice the size of France is at risk of being cut down, following news from the Democratic Republic of Congo (DRC) that the government is planning to re-open its forest to new logging companies. This comes at a time when the governments of Norway, France, Germany, the UK, and the European Union are assessing whether to support a billion-dollar plan proposed by the DRC government to protect the country's 1.55 million square kilometres of forests.

A coalition of environmental and anti-corruption organisations is calling on the DRC to maintain its moratorium on the allocation of new logging licenses, which has been in place since 2002.

"The large-scale logging of DRC's rainforest was and is a disaster," said Irène Betoko of Greenpeace Africa. "It not only harms the country's environment, but also fuels corruption and creates social and economic havoc. We call upon the DRC government to keep the present logging moratorium in place."

Lars Løvold of the Rainforest Foundation Norway (RFN): "At a time when the global community is working together to protect the world's last rainforests, a vital defence against climate change, the DRC government seems to be undermining the commitment to reducing emissions that it presented in Paris."

DRC Environment Minister, Robert Bogeza, outlining his priorities for 2016, stated that measures are being taken to lift the moratorium on the allocation of new logging licenses, citing the financial benefits this could bring: "The moratorium on granting new forestry concessions, decreed in 2002 by Ministerial Decree and reaffirmed in 2005 by Presidential Decree, has caused a huge shortfall in revenues for our country. Measures are underway for the Government to lift it."

However, Joesph Bobia of Réseau Ressources Naturelles (RRN) said: "The argument that logging can significantly contribute to government revenues is completely unfounded. Around a tenth of the DRC's rainforest is already being logged. And yet, in 2014 the country obtained a pitiful USD$8 million in fiscal revenues from the sector – the equivalent of about 12 cents for every Congolese person."

Simon Counsell of the Rainforest Foundation UK said: "The expansion of industrial logging in the Congo's rainforests is likely to have serious long-term negative impacts on the millions of people living in and depending on those forests. We urge the government of DRC to instead promote community-based forest protection and alternatives to logging that will help the country's population prosper."

Reducing Emissions through Deforestation and Degradation (REDD) is an international effort under the UN climate treaties to combat carbon emissions by protecting the world's forests. The DRC's national strategy for REDD has been under negotiation for six years and will be submitted to international donor governments for approval this year.

The moratorium on the allocation of new logging titles was issued by Ministerial decree in 2002, in an attempt to regain control of the country's timber industry, which was riddled with illegal logging and corruption. The DRC accounts for a tenth of the world's remaining tropical rainforests. Many species, such as the bonobo and okapi, are only found in these ecosystems. Some 40 million people in the country rely on these forests for their livelihoods.
