Reconstructed mean maximum temperature in our record shows warmer conditions during the 19th century (1780�1880 AD) than in the 20th century (Fig. 3D and Figs. 3D and S3). This pattern coincides with above average spring-summer temperatures during the 19th century, reconstructed from a completely independent 600-year record based on varved sediments from El Plomo Lake, Patagonia at 47� S (Elbert et al., 2015; Fig. S3, r = 0.22, p < 0.001, for the period 1780�2009).

Interesting. I believe in the Northern Hemisphere it was actually pretty cool in that period.

It was called the Little Ice Age for a reason. When it ended everything got warmer until finally Al Gore popped up with "OMG we're all gonna die.

When everybody else ('not me' thought Al, but everybody else) uses gas and electricity to make their lives better it overheats the planet and we (actually you) are all gonna die" Some maroons were buying it so Globalists and other Progressive Socialist political types started rubbing their hands together and thinking "Score!"

But actually climate we wouldn't expect popping up in tree ring data isn't unusual. If you stick with the tree ring data we've seen weird tree ring results before.

There's this guy who calls himself a scientist named Michael Mann. He came out with something called the "hockey stick graph". It showed temperatures remaining static then suddenly rising like a hockey stick. In order to do that he had to do something called "hide the decline."

Basically he used tree ring data, from the medieval warm period through the little ice age then about the time the little ice age ended he substituted that data with the thermometer data set. If he had stayed with tree rings it would have showed temperatures declining - the exact opposite of what he wanted to show.

For a number of reasons tree ring data is not reliable as a temperature proxy over longer periods of time.

Forgive me for being dismissive but can any lab-coat explain how the fuck this bullshit "research" is of any use? forget about its veracity.

Reconstructed mean ...

Yeah, things change.
