Global Warming

Plans to end global warming hinge on driving net greenhouse gas emissions to zero (plus or minus a few gigatonnes). It’s not going well. CO 2 emissions hit an all-time high last year, and for the first time average temperatures on Earth rose 1.5 °C above preindustrial levels. To limit…

September 11, 2025 4 min read A new study finds that one quarter of heat waves between 2000 and 2023 would have been “virtually impossible” without global warming—and can be attributed to the emissions of individual energy producers By Jeff Tollefson & Nature magazine Heatwaves are getting more severe, and…

Experimental climate interventions in the world’s oceans are moving ahead in a regulatory vacuum, raising concerns among scientists about potential risks, Mongabay staff writer Edward Carver reported. The projects, known as marine-climate interventions, aim to tackle global warming or help people and ocean life adapt to climate change...Read More

Achieving net-zero greenhouse gas emissions by 2050 will require removing carbon dioxide from the atmosphere, according to the Intergovernmental Panel on Climate Change, the world’s foremost authority on the topic. But only some types of carbon removal are actually effective — and these are largely not the kind that major companies…

Topline A scientist whose research has been cited by podcaster Joe Rogan as evidence against global warming has spoken up to say Rogan is grossly misunderstanding the study he says supports his claims, making her the latest scientist to slam him over "old-school denier nonsense.” Joe Rogan on April 13,…

Around 85 scientists wrote a 440-page rebuttal to the government’s report, accusing it of taking the word of some contrarians who based their conclusions on discredited studies, bypassed peer review and misinterpreted evidence Climate experts in the US have rejected a report released by the Trump administration in July, seeking…

Now there’s growing evidence that it might unleash planet-warming carbon By Kate McMahon edited by Andrea Thompson A trawl net,…

Two decades ago, Hurricane Katrina spun up like a massive atmospheric engine, using warm ocean water as fuel. Making landfall as a Category 3 storm with maximum sustained winds of 125 mph, it devastated New Orleans — surging seawater over levees, killing nearly 1,400 people, and causing more than $150…

The world will warm more than expected due to future changes in ozone, which protects Earth from harmful sun rays but also traps heat as it is a greenhouse gas. While banning ozone-destroying gases such as CFCs has helped the ozone layer to recover, when combined with increased air pollution…
