Have you noticed it getting a bit chilly at night recently? Do you think we will have a mild ‘global warming winter’, or could it be a sort of icy ‘nuclear winter’?
♦ Ed note: Global heating causes both extreme heat and cold. A 2019 article in Forbes clarifies that a warmer Earth makes sudden stratospheric warming events more likely and more frequent. Those events destabilise the polar vortex, and can bring cold air down into the mid-latitudes, and cause extreme cold events (https://bit.ly/2RObNGl).
