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.
It is currently the beginning of Feb and our normal weather here is a few days of snow, usually a few inches, usually at least one large to shut everything down (like 10+"). Overcast. In the 20s and 30s (F).
I went skiing on Saturday and have never seen so much literally bare ground outside of the very early or very very late season.
I went to a protest today. Parked a distance away and walked. It was 68°. It feels like the end of April. We got almost no snow - only like a foot unseasonably early in the middle of November. The wildfire season this year is going to be rough, and the summer will be brutal.
