Record global temperatures in March illustrate threat to climate goals
Global temperatures hovered at historic highs last month, and Europe experienced its warmest March, suggesting international climate goals could be moving out of reach.
The average temperature in March in Europe climbed to above 6 degrees Celsius (42.8 Fahrenheit), which is 0.26C (0.468F) above the previous hottest March in 2014. The average global temperature last month was 1.6C (2.88F) higher than in pre-industrial times, the European Union's Copernicus Climate Change Service (C3S) said on Tuesday.
The findings, contained in C3S's monthly report, underscore growing concerns that the international goal of limiting global warming by the year 2100 to 1.5C (2.7F) above pre-industrial levels is slipping out of reach.
Scientists have warned that every fraction of a degree of global warming increases the intensity and frequency of extreme weather events such as heatwaves, heavy rainfall and droughts.
Samantha Burgess, strategic lead at the European Centre for Medium-Range Weather Forecasts, which runs the C3S service, noted that Europe experienced extremes in both heavy rain and drought in March.
Europe last month recorded 'many areas experiencing their driest March on record and others their wettest March on record for at least the past 47 years', Burgess said.
Scientists said climate change also intensified an extreme heatwave across Central Asia and fuelled conditions for extreme rainfall in countries like Argentina.
Arctic sea ice also fell to its lowest monthly extent last month for any March in the 47-year record of satellite data, C3S said. The previous three months also set record lows.
The EU monitor uses billions of measurements from satellites, ships, aircraft and weather stations to aid its climate calculations. Its records go back to 1940.
The main driver of climate change is greenhouse gas emissions from burning fossil fuels, according to climate scientists.
But even as the costs of disasters due to climate change spiral, the political will to invest in curbing emissions has waned in some countries.
United States President Donald Trump has called climate change a 'hoax', despite the global scientific consensus that it is human-caused and will have severe consequences if not addressed.
In January, Trump signed an executive order to have the US withdraw from the landmark Paris climate agreement, dealing a blow to worldwide efforts to combat global warming and once again distancing the US from its closest allies.
In 2015, nearly 200 nations agreed in Paris that limiting warming to 1.5C above pre-industrial levels offered the best chance of preventing the most catastrophic repercussions of climate change.
However, Trump's order says the Paris accord is among a number of international agreements that do not reflect US values and 'steer American taxpayer dollars to countries that do not require, or merit, financial assistance in the interests of the American people'.
Friederike Otto of the Grantham Institute – Climate Change and the Environment at Imperial College London told the AFP news agency that the world is 'firmly in the grip of human-caused climate change'.
'That we're still at 1.6C above pre-industrial is indeed remarkable,' she said.

Trump withdraws nomination of Musk ally Isaacman as NASA head
dpa Washington US President Donald Trump has withdrawn his nomination of billionaire tech entrepreneur Jared Isaacman as NASA head 'after a thorough review of prior associations.' On taking office in January, Trump proposed Isaacman, a close associate of SpaceX boss Elon Musk, to succeed Bill Nelson at the helm of the space agency, who left at the end of the presidency of Joe Biden. According to US media reports, Isaacman was to have been approved by the Senate shortly. But on Saturday evening, Trump wrote on his Truth Social platform that he would soon announce a new nominee 'who will be Mission aligned, and put America First in Space,' without elaborating further. In an indication of growing distance from Trump, Musk responded on his own social media platform X: 'This sucks. I can't think of a better person for the job than Jared.' Trump's decision took observers by surprise, as he had praised Isaacman highly in December before taking office, saying he would 'drive NASA's mission of discovery and inspiration.' Responding to Trump's decision, Isaacman posted on X that he was grateful for the opportunity and said he would be cheering the president and NASA on. 'I have not flown my last mission - whatever form that may ultimately take,' he said. Isaacman has participated in two private space missions. In 2021, he was one of the first non-professional crew in space, joining three others on a three-day trip around Earth. In September last year, he was part of the Polaris Dawn mission alongside three other space tourists, undertaking a space walk. In both missions he collaborated with Musk's SpaceX. Citing unnamed sources familiar with the matter, the New York Times reported that Trump had told associates he intended to 'yank' Isaacman's nomination after being told that Isaacman had donated to prominent Democrats. The decision was the latest example of how Trump 'uses loyalty as a key criterion for top administration roles,' the daily wrote.

US to tighten AI chip export curbs to China despite Nvidia CEO's pushback
ANI Washington The Trump administration announced on Wednesday that it will continue its efforts to prevent advanced artificial intelligence (AI) technology from reaching China, dismissing requests from Nvidia's CEO Jensen Huang to relax chip export limitations to the country. 'We have great respect for Jensen,' stated Sriram Krishnan, a senior policy adviser for AI at the White House, during a Bloomberg Television interview. 'There remains bipartisan and widespread concern about the potential implications of these GPUs once they are physically in China,'Krishnan said. Though the Trump administration still perceives a security threat from expanding AI chip exports to China, Krishnan acknowledged that he aligns with Huang's perspective that restrictions on a broader array of US trading partners should be reassessed. According to the Taipei Times report, the Trump administration is reversing. It intends to replace an AI diffusion regulation established by former President Joe Biden, which, as Krishnan indicated, resulted in 'GPU haves and GPU have-nots.' 'When it pertains to the rest of the world, we aim for an American AI ecosystem that starts from the GPUs and extends to the models and everything built upon that,' Krishnan remarked. 'On this point, Jensen and I share common ground,' he added. Krishnan's comments followed Huang's strongest public criticism yet regarding the increasing US export restrictions aimed at China, Taipei Times reported.

World's richest 10% caused two thirds of global warming: Study
Agencies The world's wealthiest 10 percent of individuals are responsible for two thirds of global warming since 1990, researchers said on Wednesday. How the rich consume and invest has substantially increased the risk of deadly heatwaves and drought, they reported in the first study to quantify the impact of concentrated private wealth on extreme climate events. 'We link the carbon footprints of the wealthiest individuals directly to real-world climate impacts,' lead author Sarah Schoengart, a scientist at ETH Zurich, told AFP. 'It's a shift from carbon accounting toward climate accountability.' Compared to the global average, for example, the richest one percent contributed 26 times more to once-a-century heatwaves, and 17 times more to droughts in the Amazon, according to the findings, published in Nature Climate Change. Emissions from the wealthiest 10 percent in China and the United States—which together account for nearly half of global carbon pollution—each led to a two-to-threefold rise in heat extremes. Burning fossil fuels and deforestation have heated Earth's average surface by 1.3 degrees Celsius, mostly during the last 30 years. Schoengart and colleagues combined economic data and climate simulations to trace emissions from different global income groups and assess their impact on specific types of climate-enhance extreme weather. The researchers also emphasized the role of emissions embedded in financial investment rather than just lifestyle and personal consumption. 'Climate action that doesn't address the outsized responsibilities of the wealthiest members of society risk missing one of the most powerful levers we have to reduce future harm,' said senior author Carl-Friedrich Schleussner, head of the Integrated Climate Impacts Research Group at the International Institute for Applied Systems Analysis near Vienna. Owners of capital, he noted, could be held accountable for climate impacts through progressive taxes on wealth and carbon-intensive investments. Earlier research has shown that taxing asset-related emissions is more equitable than broad carbon taxes, which tend to burden those on lower incomes. Recent initiatives to increase taxes on the super-rich and multinationals have mostly stalled, especially since Donald Trump regained the White House. Last year, Brazil—as host of the G20 -- pushed for a two-percent tax on the net worth of individuals with more than $1 billion in assets. Although G20 leaders agreed to 'engage cooperatively to ensure that ultra-high-net-worth individuals are effectively taxed,' there has been no follow-up to date. In 2021, nearly 140 countries agreed on work toward a global corporate tax for multinational companies, with nearly half endorsing a minimum rate of 15 percent, but those talks have stalled as well. Almost a third of the world's billionaires are from the United States—more than China, India and Germany combined, according to Forbes magazine. According to anti-poverty NGO Oxfam, the richest 1 percent have accumulated $42 trillion in new wealth over the past decade. It says the richest one percent have more wealth than the lowest 95 percent combined.
