  • For 3rd straight year, no improvement in Earth’s projected warming

    For 3rd straight year, no improvement in Earth’s projected warming

    BAKU, Azerbaijan — For the third straight year, efforts to fight climate change haven’t lowered projections for how hot the world is likely to get — and recent developments in China and the United States are likely to slightly worsen the outlook, according to an analysis Thursday.

    The analysis comes as countries come together for the 29th edition of the United Nations climate talks, hosted in Baku, Azerbaijan, where nations are trying to set new targets to cut emissions of heat-trapping gases and figure out how much rich nations will pay to help the world with that task.

    But Earth remains on a path to be 2.7 degrees Celsius (4.9 degrees Fahrenheit) warmer than pre-industrial times, according to Climate Action Tracker, a group of scientists and analysts who study government policies and translate that into projections of warming.

    If emissions are still rising and temperature projections are no longer dropping, people should wonder if the United Nations climate negotiations known as COP are doing any good, Hare said.

    “There’s an awful lot going on that’s positive here, but on the big picture of actually getting stuff done to reduce emissions … to me it feels broken,” Hare said.

    The world has already warmed 1.3 degrees Celsius (2.3 Fahrenheit) above pre-industrial times. That’s near the 1.5-degree (2.7 F) limit that countries agreed to at 2015 climate talks in Paris. Climate scientists say the atmospheric warming, mainly from human burning of fossil fuels, is causing ever more extreme and damaging weather including droughts, flooding and dangerous heat.

    Climate Action Tracker does projections under several different scenarios, and in some cases, those are going up slightly.

    One projected track based on what countries promise to do by 2030 is up to 2.6 degrees Celsius, a tenth of a degree warmer than before. And even the analysts’ most optimistic scenario, which assumes that countries all deliver on their promises and targets, is at 1.9 Celsius, also up a tenth of a degree from last year, said study lead author Sofia Gonzales-Zuniga of Climate Analytics, one of the main groups behind the tracker.

    “This is driven highly by China,” Gonzales-Zuniga said. Even though China’s fast-rising emissions are starting to plateau, they are peaking higher than anticipated, she said.

    Another upcoming factor not yet in the calculations is the U.S. elections. A Trump administration that rolls back the climate policies in the Inflation Reduction Act, and carries out the conservative blueprint Project 2025, would add 0.04 degree Celsius (0.07 Fahrenheit) to warming projections, Gonzales-Zuniga said. That’s not much, but it could be more if other nations use it as an excuse to do less, she said. And a reduction in American financial aid could also reverberate even more in future temperature outlooks.

    “For the U.S. it is going backwards,” said Climate Analytics CEO Bill Hare. At least China has more of an optimistic future with a potential giant plunge in future emissions, he said.

    “We should already be seeing (global) emissions going down” and they are not, Hare said. “In the face of all of the climate disasters we’ve observed, whether it’s the massive floods in Nepal that killed hundreds of people or whether it’s the floods in Valencia, Spain, that just killed hundreds of people. The political system, politicians are not reacting. And I think that’s something that people everywhere should be worried about.”

    The major battle in Baku is over how much rich nations will help poor countries to decarbonize their energy systems, cope with future harms of climate change and pay for damage from warming’s extreme weather. The old goal of $100 billion a year in aid is expiring and Baku’s main focus is coming up with a new, bigger figure.

    A special independent group of experts commissioned by United Nations Secretary-General Antonio Guterres issued its own estimate of costs and finances on Thursday, calling for a tripling of the old commitment.

    “Advanced economies need to demonstrate a credible commitment” to helping poor nations, the report said.

    A coalition of poor nations at the Baku talks are asking for $1.3 trillion in annual climate finance. The independent experts’ report said about $1 trillion a year is needed by developing nations from all outside sources, not just government grants.

    The report detailed how expensive decarbonizing the world’s economy would be, how much it would cost and where the money could come from. Overall climate adaption spending for all countries is projected to reach $2.4 trillion a year.

    “The transition to clean, low-carbon energy, building resilience to the impacts of climate change, coping with loss and damage, protecting nature and biodiversity, and ensuring a just transition, require a rapid step-up in investment in all countries,” said the report.

  • Amid Earth’s heat records, scientists report another bump upward in annual carbon emissions

    Amid Earth’s heat records, scientists report another bump upward in annual carbon emissions

    BAKU, Azerbaijan — Even as Earth sets new heat records, humanity this year is pumping 330 million tons (300 million metric tons) more carbon dioxide into the air by burning fossil fuels than it did last year.

    This year the world is on track to put 41.2 billion tons (37.4 billion metric tons) of the main heat-trapping gas into the atmosphere. It’s a 0.8% increase from 2023, according to Global Carbon Project, a group of scientists who track emissions. Several United Nations reports say the globe must cut emissions by 42% by 2030 to possibly limit warming to an internationally agreed-upon threshold.

    This year’s pollution increase isn’t quite as large as last year’s 1.4% jump, scientists said while presenting the data at the United Nations climate talks in Azerbaijan.

    If the world continues burning fossil fuels at today’s level, it has six years before passing 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels, the limit agreed to at the 2015 climate talks in Paris, said study co-author Stephen Sitch. The Earth is already at 1.3 degrees Celsius (2.3 Fahrenheit), according to the United Nations.

    “We clearly are not doing enough on a global scale to reduce emissions. It’s as simple as that,” said study co-author Mike O’Sullivan, a University of Exeter climate scientist. “We need to massively increase ambition and actually just think outside the box of how we can change things, not be so tied to fossil fuel interests.”

    Scientists used reported emissions from rich countries and oil industry data, O’Sullivan said. The 2024 figure includes projections for the last couple months or so. The Global Carbon Project team released figures for the four biggest carbon emitters — China, the United States, India and Europe. It also produced more detailed and final figures for about 200 countries for 2023.

    The continued rise in carbon emissions is mostly from the developing world and China. Many analysts had been hoping that China — by far the world’s biggest annual carbon polluting nation with 32% of the emissions — would have peaked its carbon dioxide emissions by now. Instead China’s emissions rose 0.2% from 2023, with coal pollution up 0.3%, Global Carbon Project calculated. But it could drop to zero in the next two months and is “basically flat,” O’Sullivan said.

    That’s nothing close to the increase in India, which at 8% of the globe’s carbon pollution is third-largest carbon emitter. India’s carbon pollution jumped 4.6% in 2024, the scientists said.

    Carbon emissions dropped in both the United States and the European Union. They fell 0.6% in the U.S. mostly from reduced coal, oil and cement use. The U.S. was responsible for 13% of the globe’s carbon dioxide in 2024. Historically, it’s responsible for 21% of the world’s emissions since 1950, a figure that matters since the gas persists in the atmosphere for centuries.

    Twenty-two nations have shown steady decreases in emissions, O’Sullivan said, singling out the United States as one of those. The biggest emission drops from 2014 to 2023 were in the United States, Japan, Germany, the United Kingdom and Ukraine.

    Europe, which accounts for 7% of the world’s carbon pollution, saw its carbon dioxide output drop 3.8% from last year — driven by a big cut in coal emissions.

    Global carbon emissions are well more than double what they were 50 years ago and 50% than they were in 1999. Emissions have gone up about 6% in the past decade.

    “This is a needed reminder of the urgency with which we need to address the cause of the climate crisis,” said PowerShift Africa founder Mohamed Adow, who wasn’t part of the study. “The problem is the fossil fuel industry is kicking and screaming for us to slow down and to keep them in business for longer. That’s why they poured money into Donald Trump’s election campaign.”

    Carbon dioxide from humanity’s burning of coal, oil and natural gas amounts to 2.6 million pounds (nearly 1.2 million kilograms) of the heat-trapping gas every second.

    Total carbon emissions — which include fossil fuel pollution and land use changes such as deforestation — are basically flat because land emissions are declining, the scientists said. That’s an important and encouraging milestone amid bad news, said University of Pennsylvania climate scientist Michael Mann
