Climate change target of 2C is ‘dead’, says renowned climate scientist
Climate change target of 2C is ‘dead’, says renowned climate scientist
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.

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 just hope that it doesn't end up like Snowpiercer!
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.
Let's fix the environment by fuckin it up more.
We have been fucking it for centuries. And by the looks of things, that's not stopping any time soon. I'd rather we have something we can do besides hoping that certain people decide now's the time to seriously address climate change.
