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.
I think it’s sunk cost. It’s too late for them to admit that they were wrong because now it’s too late to do anything. And admitting they were wrong this whole time would mean that there was time to do something and they squandered it to the detriment of not only their own descendants, but for literally every human on the planet.
Their ego will not allow it.
