Sudden Climate Change

Using data from ice core records, a Danish glaciologist has discovered that during a series of ten glacial and interglacial periods in the Pleistocene Epoch before the Holocene there were wild and sudden fluctuations in climate conditions. This pattern of sudden and rapid shifts makes the 11000 years of climatic stability during the Holocene epoch following the end of the Ice Ages (Pleistocene) look unusual. This stable period in which temperatures were within 1 degree above or below current norms lasted up to the Industrial Revolution about 300 years ago,  It was in this stable period of minimal climate fluctuation that human civilisations developed. To elaborate these new findings and their implications, Yale Climate Connections today posted this video.
