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.

      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.

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

          How about some sort of hot dog helicopter?

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