Scientific analysis confirms accelerating global warming trends

A study published in Geophysical Research Letters, led by researchers from the Potsdam Institute for Climate Impact Research, identifies a statistically significant acceleration in global warming. Data analysis from five major sets, including NASA, NOAA, and ERA5, indicates a heating rate of approximately 0.35 degrees Celsius per decade over the last ten years. This exceeds the average rate of less than 0.2 degrees per decade observed between 1970 and 2015. Climatologist Grant Foster notes this is the highest rate of acceleration since instrumental records began in 1880, even after accounting for natural factors like El Nino and volcanic activity. Separately, the World Meteorological Organization's 'State of the Global Climate 2025' report, released on March 23, 2026, confirms 2015-2025 was the warmest decade on record. The report states that 2024 remains the hottest year with a 1.55-degree increase over pre-industrial levels, while 2025 ranks among the top three hottest years with a 1.43-degree rise. These findings highlight rising greenhouse gas concentrations and irreversible impacts on global climate systems.
