Study Finds Global Warming Nearly Doubled to 0.63°F a Decade Since 2015

Summary
Research published in Geophysical Research Letters says with 98% statistical certainty that warming has accelerated, with Earth heating by 0.63°F per decade since 2015 versus about 0.36°F from 1970 to 2015.
The authors reached that conclusion by filtering observational data for El Niño, volcanism and solar variation, isolating the human-driven trend from short-term natural swings that had previously obscured the signal.
1.5°C of warming is already close in annual temperature records, and the researchers say the recent pace would put the world on track for a long-term exceedance of the Paris threshold before 2030.
That sustained overshoot could lock in more intense heatwaves, droughts, wildfires, heavy rainfall and floods, while raising risks of tipping points such as ocean-circulation disruption, permafrost thaw and coral reef collapse.
The study says the trajectory still depends on how fast global CO2 emissions from fossil fuels fall to zero, warning that current politics could let warming continue at the same pace or faster.
With the 1.5-degree limit likely breached by 2030, are current climate goals obsolete, or can we still reverse catastrophic ocean tipping points?
If reduced air pollution is unmasking extreme heat, could our attempts to clean the air actually be accelerating the global climate crisis?
As nighttime temperatures surge faster than daytime highs, how will global infrastructure survive the rapidly expanding footprint of hazardous heat stress?
Global Warming Accelerates to 0.35°C per Decade: Causes, Consequences, and the Race to Avoid Climate Catastrophe
Overview
Global warming is accelerating at an unprecedented rate, driven mainly by the relentless rise in fossil fuel emissions and the sudden removal of cooling aerosols from ship pollution. This rapid warming is pushing the world past critical temperature thresholds, narrowing the chance to avoid dangerous climate tipping points like Amazon rainforest dieback and ice sheet collapse. As a result, extreme weather events are becoming more frequent and severe, displacing hundreds of thousands of people. While international legal rulings call for stronger climate action, real progress depends on both global cooperation and empowering local communities to build resilience and protect vulnerable populations.
