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 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

        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 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.
