2/ summary: we may have thought that the data and statistics of prior hockey sticks was bad, but the data and statistics of the new IPCC poster hockey stick is "worse than we thought".

despite years of being told that defects in prior hockey stick temperature reconstructions "don't matter" because the Hockey Stick "doesn't "matter", the first figure of new IPCC Summary for Policy-Makers is a Hockey Stick.

3/ I remind readers who may not be familiar with my approach that showing that IPCC didn't prove their point does not prove that Medieval Warm Period was warmer than present or that there wasn't substantial warming in 20th century.

9/ For those climate scientists that complain that it's the warmest year in 100,000 years and demand that we Make Climate Great Again: here's a map of Canada 20,000 years ago. We're lucky that we live now and not then.pic.twitter.com/fQgfMkdhEL
