The study presents the atlas of unburnable oil in the world, designed based on environmental and social criteria to reduce CO₂ emissions in the atmosphere, combat the effects of climate change and comply with this international treaty, signed in 2015 in Paris as part of the UN Climate Change Conference (COP21).

The worrying findings, based on temperature records contained in sea sponge skeletons, suggest global climate change has progressed much further than previously thought. Human-caused…

Credit: CC0 Public Domain The alarm bells are loud and clear. Federal and international climate officials recently confirmed that 2023 was the planet's hottest year on record—and that 2024 may be even hotter. With a global average temperature of 58.96 degrees, Earth in 2023 was within striking distance of a dangerous limit: 2.7 degrees of warming over…

It's official: 2023 was Earth's hottest year ever recorded, beating the previous record set in 2016 by a huge margin.Last year was also the first in which the world was close to 1.5°C (1.48°C) hotter than the pre-industrial average (1850-1900). We are brushing against the threshold scientists urged us to limit long-term warming to.Some scientists, including former Nasa climatologist James Hansen, predict 2024 will be humanity's first year beyond 1.5°C. As what were once dire warnings from climate experts become our…

DOI: 10.1016/j.oneear.2023.11.004 A new study shows that economic growth rates make a big difference when it comes to prospects for limiting global warming to 1.5°C, as per the Paris Agreement. A recent study by the Institute for Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) shows that pursuing higher economic growth may jeopardize the Paris goals and leave no…

They have proposed a solution. While the global average temperature in a…

DOI: 10.1093/oxrep/grad043 To meet the goals of the Paris Agreement and limit global heating to 1.5°C, global annual emissions will need to drop radically over the coming decades. A new paper from climate economists at the University of Oxford…

Imagine you started a fire in your neighborhood, down the street from your house. You didn't mean to—you’re no arsonist—but there it is, blazing before your eyes. Your neighbor’s house is about to go up in flames. What do you do?There is only one answer, of course: You try to put it out. You run over with buckets and hoses. You do everything you can to be useful. As long as there is a chance of saving your neighbor's home, no matter how small, you keep working. After all, you started it. You should be the very last person…

There was thus immense pressure on all at the conference to achieve a robust outcome. And a group of politicians and policymakers representing some of the world’s poorest countries had a very specific and controversial requirement for what it should contain. James Fletcher, of St Lucia, recalls that he and his fellow representatives of Caribbean states were “very clear in our minds that 1.5°C was a red-line item. It was one of the things that we said kind of silently: that we would be prepared to walk away…
