On June 19, 2026, four respected climate scientists — Raymond Pierrehumbert, Julia Slingo, Michael Mann, and Valerie Masson-Delmotte — penned an article for The Guardian that explained the danger lurking within geoengineering schemes. Not only will they be frightfully expensive, but once begun, they cannot be allowed to lapse. They must continue for a century or more to avoid disastrous changes in the environment that could endanger life on Earth as we know it. The scientists call that threat “termination shock.”
How difficult the transition will be to a sustainable global economy was on display in Bonn, Germany this week, where climate talks in advance of the COP 31 conference later this year turned rancorous. “We have seen side-stepping and stalling,” said UN climate chief, Simon Stiell. “We’ve seen geopolitical tensions wash through these halls. We simply cannot afford to reopen previous decisions, to renegotiate existing targets, or to backslide. It’s cooperation, not fierce competition, that we need.”
A group of nations led by Saudi Arabia and including India objected to language reaffirming climate science. India — where extreme heat is killing more and more people every year — is objecting to a reference to climate science? That is insanity!
