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.
No, but it’s easy to predict given that the trends of the last several decades can show where we’d be in the next and the trend is: global temperatures are fluctuating more violently than the year before and occurrences of extreme weather are increasing. Additionally, nothing has been done during that time to reduce the impacts globally.
It’s scary but, let’s face it: we’re a virus that’s killing our host.
