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.

    The scary part is that seems to make no difference (to people, corps, countries). Has anyone changed anything based on passing that target? Will the anyone change their minds or behavior with this new projection?

    Maybe I’m just cynical with the disaster of the US elections - we were finally making a little progress, finally had reason to hope, but we just threw that away
