“Sceptics” often cite ice core data to make a point along the lines that current warming isn’t a problem and is within normal climate variability. And often they cite research papers and data to prove this point.
However almost every single time they display temperature records out of context, and more often than not come to entirely different conclusions than are in the research paper or is held by the author(s). One of the websites that’s notorious for this is the website Watts Up With That (WUWT).
One of these examples is a research paper on the Greenland Ice Sheet by Dr Richard Alley, who has publicly said that this is not what his research shows.
Cheers for Greenman3610 for making another excellent Climate Debunking Video.
