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.

    I saw it originally watching Simon Clark. Reviewing, it looks like the chart shown is actually a great example of a terrible graph; it uses 5 year periods then switches to 1 year periods without clear indication, making it look flatter than it would otherwise. If I adjust for this in a photo editor, emissions have barely slowed. I was misled, sorry for passing that on and thanks for questioning it.

      Good on you to have integrity.

      But yeah, that’s what I gather, too, whenever I check. Nothing we do has an impact. I’m hoping the huge renewables push in China over the last few years might finally have an effect, but :(
