If a “Little Ice Age” isn’t good enough for the AGW hype artists humanity may just get to try a serious ice age in the next 1 or few thousand years....... that will be vastly more difficult to cope with than anything that has been suggested by even the most committed AGW fanatics.
They could of course use the historical record to estimate temperature. The Romans used to grow grapes just south of Hadrians wall, not possible today. Even pictorial records of earlier dress styles give clues to a much warmer early period.
Saving in my ever-growing file!
Thanks you, Ernest.
Here's the basic "hockey stick". I'm showing it because, contrary to popular skeptical belief, it did have an MWP, diluted because it attempted to be a global compilation and the MWP was most strongly felt in Europe and North America (the LIA was more evenly global). There's a lot more variability in the GISP2 core data, because Greenland is subject to a lot more variability due to the influence of the surrounding polar ocean waters. You can see in the lower plot that temps are higher from 1000-1400 than from 1400 to 1850. There was a big eruption (Kuwae) in 1452 that may have caused a pre-sunspot minimum cooling -- that dip is easy to see.
I tried to figure out what is represented by the "IPCC 1995 data", but I couldn't find it. Not a lot of information is provided at the linked Web site.
Great article.
