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.

    Some good news:

    • emission rates have plateaued; we are still destroying the planet, but no longer accelerating the rate at which we do it
    • Solar panels (unsubsidized) are the cheapest method of electricity generation as of 2022
    • there is a fundamentally limited amount of fossil fuels, so as long as we don’t turn to Venus 2.0 by 2100 we will deplete most coal and oil and it will be possible for our ancestors to repair the planet over the following centuries.

    Yeah I know even this “good news” is bleak, but it’s worth celebrating. There is some hope.
