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.
Not a shock. We have not done enough.
If your mean “we” as humanity, yes. If you mean “we” like you and me, then no.
The main responsible didn’t do enough and that’s not us.
Only a few decided to ignore all the warnings, so money could be made.
