1875 was coldest in 10,000 years, Warming A Good Thing

‘We made ourselves an extremely poor experiment when we started to observe meteorology at the coldest time in the last ten thousand years.’ – Indeed.

Science Matters

Jørgen Peder Steffensen, of Denmark’s Niels Bohr Institute, is one of the most experienced experts in ice core analysis, in both Greenland and Antarctica. In this video he explains a coincidence that has misled those alarmed about the warming recovery since the Little Ice Age. And if you skip to 2:25, you will see the huge error we have made and the assumptions and extrapolations based on that error. Transcript below is from closed captions with my bolds and added images.

This ice is from the Viking age around the year one thousand, also called the medieval warm period. We believe that in Greenland the Medieval Warm Period was about one and a half degrees warmer on average than today
