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.

      Its very unlikely for these reasons:

      • limited lifetime
      • we have already seen volcanic eruptions which put a lot of SO2 into the stratosphere, and thet did not cause an ice age, so it’s clearly fine if we don’t put too much

      Anyway, that’s what research is for.
