So far your only counter argument has been ad-hominem about CATO. OK, what did CATO miss mentioning? Well for one thing the fact that most of Antarctica is gaining ice. Here's something they didn't miss, but that I didn't quote before "In 2000, Glen MacDonald and several coauthors published an eye–opening perspective on the climate history of the Eurasian arctic in the highly respected journal Quaternary Research ("quaternary" is the era of recent ice ages, beginning about 1.8 million years ago) in which they examined radiocarbon dates of old trees deposited in the tundra, far north of today's northernmost trees. In that region, the tree line is generally over 100 miles south of the Arctic Ocean. But for much of the era from 3,000 to 9,000 years ago, the forest extended right to the sea. Summer temperatures -- the same ones that melt Greenland's ice -- are what determine the Northern treeline. MacDonald had to conclude that "Over much of northern Eurasia [during that period], summers may have been 4.5 to 12.6°F warmer than today."" cato.org
