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.

    You dont know the future and you dont know what hope is left. Stop being such a defeatist. Either do something positive or go smoke some weed or something…

      You dont know the future

      Nope. But I know humanity and I’ve picked up a history book.

      Again, look around you. Look at world politics. We’re moving in the opposite direction of addressing climate change. As long as money is our prime motivator, we will keep acting in direct opposition to the wellbeing of our planet. And, another spoiler alert, money is going to be our motivator for the foreseeable future. Probably forever. We will only address the issue when it seriously affects every man, woman, and child on this planet and by then it will be far too late.

      Humanity was always going to destroy this planet on a long enough timeline. It was inevitable. I’m not a defeatist. I’m a realist.

      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.

        Only the people who sit on their ass all day are the virus. Just be honest and confess your just to lazy to even try and make a difference.
