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.

    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?

    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

        Okay my next big idea is the bodega van. Instead of an ice cream truck for kids it’s a convenience store for adults in the suburbs. It’s 6:47pm and you’re out of milk, tissues, and you forgot to buy broccoli for your dinner. Oh shit it’s the bodega van music. Brb, gotta walk down the block instead of spend 20m in a car, parking lot, store, line, back. As long as the margins are less than doordash it’s worth using.

        Cmon please tell me I have one original thought in this wide world.

          We need ice cream truck reform first. The damn things never stay still long enough for me to catch them

          Sorry we had grocery buses in Finland driving out to villages at least since the 80’s. Not sure if they exist anymore

              And veggies. Repurpose the heli to mass produce chopped salads from the sky

    Not a shock. We have not done enough.

      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.
