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.
may be, but with the feedback loops fully contributing then, the 6°C goal will be delayed a few decades.
and by the way, the political was to stop it at 1.5°C by 2050. nobody ever assumed 6°C an acceptable outcome.
I’m just showing that we are lowering the projection curve due to our efforts. 2 degrees is too hot by far but progress is being made, we aren’t just ignoring the situation.
