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?
All of last year, every time they said this month was the hottest on record, I kept saying “So far…”
