In the 60’s we were going to put hundreds of ICBM’s in caverns carved into the ice sheets. Recent analysis of the ice dug up in the test beds shows that what is now a mile thick ice layer was a life filled tundra as recent as 460,000 years ago.
The problem:
“Scientists also know that at that time, global temperatures were similar or slightly warmer than what they are today. However, back then, atmospheric concentrations of planet-warming carbon dioxide were about 280 parts per million, compared to today’s 422 parts per million.”
So carbon dioxide is not linked to climate temperature.

Brian Zinchuk: How a real life Hoth ice base in Greenland in the 60s calls CO2 concerns into question today
Whoa, there, Nelly! You’re telling me that carbon dioxide levels were a full third less than they are at this very moment, and yet the northernmost portions of Greenland (the most likely to freeze) was tundra? It did not have most of a mile of ice covering it? Well below the supposedly crucial...
