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.
Not true at all. Compare:
“lag time before they actually start causing heat” and
“the timing between an emission and the maximum temperature response is a decade on average”
A “start” and a “maximum” are completely different. IR absorption starts immediately and increases over years to a maximum.
