Sometimes, life is about perspective.
Idiot politicians who don’t understand evolution, life, or X risk will probably be the ones that, if they enact policies like the Green New Deal, will cause catastrophic pain on human life. If life on Earth survived the Chicxulub impactor that exterminated 75% of all species, including all non-avian dinosaurs, 66 million years ago, it will probably survive a gradual 2 degree increase in temperature.
The Chicxulub impact event was an ~100 million megaton blast that devastated the Gulf of Mexico region.
The blast generated a core of superheated plasma in excess of 10,000 degrees. Although that thermal pulse would have been relatively short-lived, a handful of minutes, it would have been lethal for nearby life.
The Chicxulub Impact event produced a shock wave and air blast that radiated across the seas, over coastlines, and deep into the continental interior. Winds far in excess of 1000 kilometers per hour were possible near the impact site, although they decreased with distance from the impact site. The pressure pulse and winds would have scoured soils and shredded vegetation and any animals living in nearby ecosystems. An initial estimate of the area damaged by an air blast was a radius 1500 kilometers. There are several factors that can affect this estimate, so the uncertainty might be better reflected in a range of radii from ~900 to ~1800 km. The travel times are quite short, so this effect would have occurred in advance of any falling debris ejected from the Chicxulub crater.
