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.
We should put research into stratospheric aerosol injection. We need an insurance to limit climate change if emissions don’t go down fast enough.
We know it works, and it’s at least not catastrophically unsafe as we have already done it with container ships, and seen it happen at bigger scale with volcanic eruptions.
Let’s fix the environment by fuckin it up more.
