Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.

      Because those all vary a lot over the course of years, so if you keep them in you can’t tell how much of the change of global temperatures is going to stick around for decades or millennia. That persistent change is called “global warming”.

      Back in the early 2010s people were saying global warming is fake because global temperatures hadn’t gone up significantly in 15 years. This was the case because all those effects happened to result in temporary cooling. They were liars, but so would we be if we pretended El Niño was global warming.
