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.

    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?

      lots of folks said it was not going to happen. Last year was really recognizing there was absolutely no way its happening because it had actually passed it already so there is no way we were not passing it as we have. you will see something when we pass it about how now its impossible not to im sure soon enough.

      All of last year, every time they said this month was the hottest on record, I kept saying “So far…”

    We either become mole people, dolphin people, or space people

    Maybe oxygen clubs will be the new thing in 50 years to get out of the smog/humidity

      Apparently some of us “dril baby drill” and we’ll make those profits when we get there

      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.

    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.
