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.
30 C is what you’d probably consider a nice warm summer (86 F). 40 C is 104 F. I’ve seen mention of some places in Europe or Asia hitting 50 C, which is insane. Just add 18 more F to 104.
