Research from the Potsdam Institute for Climate Impact Research (PIK) indicates that the pace of global warming has accelerated significantly since approximately 2015. 

Studies analyzing multiple global temperature databases, including those from NASA, NOAA, and the European ERA5 system, show that the planet has warmed at a rate of roughly 0.35°C per decade over the last ten years. This is nearly double the average rate of just under 0.2°C per decade recorded between 1970 and 2015. 

To confirm these findings, researchers accounted for natural climate fluctuations, such as El Niño, to ensure the trend is statistically significant. The findings suggest this is the fastest warming rate recorded since systematic temperature tracking began in 1880.
