Michael Mann, in a Facebook posting featuring lots of UPPERCASE words: AR5 features "a STRENGTHENING of the original Hockey Stick"

Michael E. Mann - There is an amusing and rather... | Facebook
There is an amusing and rather well-coordinated untruth being circulated & promoted in climate change denial circles & right wing media that promote their propaganda that the IPCC has "trashed" the hockey stick in the latest, to be released 5th assessment report, to be released next week. In fact, what the IPCC states in a HIGHLIGHTED BOX in the Working Group 1 Summary For Policy Makers (pending any changes in the final draft) is (my emphasis)

"Analyses of paleoclimate archives indicate that in the Northern Hemisphere, the period 1983–2012 was VERY LIKELY THE WARMEST 30-year period LAST 800 YEARS (high confidence) and LIKELY THE WARMEST 30-year period of the LAST 1400 YEARS (medium confidence). 6 {2.4, 5.3}"

That is in fact a STRENGTHENING of the original Hockey Stick (and Third Assessment Report) conclusion that recent warmth was LIKELY unprecedented for the PAST 1000 YEARS.
