it's cool

      Well the fun thing about this is the temperature of the north Atlantic influences the rate of melting of the Greenland ice sheet, and scientists are predicting that if the ice sheet collapses, that'll blow the AMOC, and if the AMOC goes, the mean temp in Europe drops 17 C. Winter in Western Europe would start looking like winter in Scandinavia.

          What's happening right now is that the AMOC helps balance out heat between the high latitudes and the tropics, so if it stops, that heat just gets stuck at the equator. Which is bad for a lot of people in a lot of ways. Mexico City dries up, the Amazon flips to savanna, monster hurricanes for the gulf and Atlantic coasts. General meteorological chaos and anarchy.

            so what your saying is, global warming in the tempretzones is not real?

            also what is Meterological anarchy, is it when the weatherman says what the weather is going to be without consulting any data?

              Global warming is happening everywhere, it's just unevenly distributed. AMOC collapse represents a temporary disruption to the trend in a specific region, but the temperature is going up for western Europe now and it'll continue to rise from the dip, if/when it happens.

              "Meteorological anarchy" is just a joke referencing the fact that weather (especially extreme events) will get more erratic and harder to predict. Weather prediction works now because we have a lot of historical data to draw upon; it'll stop working once the underlying drivers of those historical weather patterns shift. No shade on human anarchists.

        You mean winter in Siberia

        Scandinavia implies the parts of it where people actually live, which are as cold as the meadows of Pennsylvania

        and if the AMOC goes, the mean temp in Europe drops 17 C

        btw do you have a source/citation for this? Like that it would be specifically that amount?

          I'm not aware of anything saying that drastic of a swing for the majority of Europe, however there are some countries that could experience a swing of that magnitude in just a few years. It's difficult to say what exactly will happen when the AMOC collapses, and there's a chance global warming outpaces the cooling from it in some of Europe
