Study Confirms Accelerated Global Warming Rate

A new study has concluded that global warming is accelerating at an unprecedented rate, with temperatures rising nearly twice as fast over the past decade as in previous decades, potentially pushing the planet past the critical 1.5 degrees Celsius threshold before 2030.

Published in Geophysical Research Letters, the analysis by Stefan Rahmstorf of the Potsdam Institute for Climate Impact Research and statistician Grant Foster examined datasets from five major organizations, including NASA and NOAA. The researchers adjusted for natural variations such as El Niño events, volcanic eruptions and solar activity to isolate the underlying warming trend. Their findings show the Earth warmed at about 0.2 degrees Celsius per decade from 1970 to 2015, but the rate has jumped to approximately 0.35 degrees Celsius per decade since then, with over 98 percent statistical certainty across all datasets. The shift became evident around 2013 or 2014, placing the world on a faster path toward the Paris Agreement's 1.5-degree limit, established in 2015 by 195 nations to avert severe climate impacts.

This acceleration aligns with observations from James Hansen, the Columbia University scientist who...
