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.

    Spoiler Alert: Look around you. Humanity is not going to address this issue. Enjoy your life and if you have kids, let them know their futures and their kid’s futures etc are going to be progressively bleaker.

      when i was a kid it was 6°C by 2100, but we have reduced this trajectory to 2.9–3.4°C

    Wow, wasn’t it just last year when they took the 1.5° target off life support and called it?

    Now the 2° is dead? Are we killing off 2.5° by summer?

      If your mean “we” as humanity, yes. If you mean “we” like you and me, then no.

      The main responsible didn’t do enough and that’s not us.

      Only a few decided to ignore all the warnings, so money could be made.
