The title, 'The Polar Bear Catastrophe That Never Happened' (2019) is sure to get the doomsters tongues in a muddle. Global warming was supposed to melt the sea ice in the Arctic Ocean and cause the polar bears to suffer – and fall into decline. Instead, they are thriving. Why not – there was a lot less summer sea ice in the Arctic during early to mid Holocene – and polar bears probably thrived at that time as well. In fact, there was a fall in sea ice during the 1930s that was equally as drastic as the 2000s, if not more so. You only have to read HH Lamb – the UK's first climate scientist.
