Washington DC, Aug. 2 -- Global warming appears to have shifted into a faster gear. After removing the effects of El Nino, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35degC per decade over the past ten years, compared with just under 0.2degC per decade from 1970 to 2015.

According to the study published on the Science Daily website, the acceleration, which became visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.

Global warming has sped up since around 2015, according to a new analysis from the Potsdam Institute for Climate Impact Research (PIK).
