Summary
Renowned climate scientist James Hansen warns that limiting global warming to 2°C is no longer possible due to underestimated climate sensitivity and reduced sun-blocking pollution from ships.
His study suggests warming could hit 2°C by 2045, increasing extreme weather and accelerating ice melt. The research challenges IPCC models, arguing for a higher climate sensitivity estimate.
Hansen calls for carbon taxes, nuclear energy, and geoengineering research.
He warns of an Atlantic ocean current collapse within 20-30 years.
Wow, wasn’t it just last year when they took the 1.5° target off life support and called it?
Now the 2° is dead? Are we killing off 2.5° by summer?
lots of folks said it was not going to happen. Last year was really recognizing there was absolutely no way its happening because it had actually passed it already so there is no way we were not passing it as we have. you will see something when we pass it about how now its impossible not to im sure soon enough.
All of last year, every time they said this month was the hottest on record, I kept saying “So far…”
