Prof James Hansen says pace of global heating has been significantly underestimated, though other scientists disagree

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.

    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.
