"The Climatic Research Laboratory (CRL) was a U.S. Army military clothing and equipment test site formerly located at Lawrence, Massachusetts from 1943 to 1954.
The lab tested textile and insulating materials and was capable of simulating climatic conditions throughout the world (e.g., desert, rain forest, tundra, mountain). A 'Jungle Room' was maintained for thermal physiological testing on human volunteers. Field trials were conducted by the lab at sites such as the Dolly Copp Test Site at the foot of Mount Washington, New Hampshire."
https://en.wikipedia.org/wiki/Climatic_Research_LaboratoryWhat is really irritating in the whole green house gas discussion is the fact that in the forties of the last century it was possible to make real climatic experiments and now, it is not possible anymore. That is really strange, very strange.
That is so strange that one is asking oneself if the world is really only shortly before doomsday because of "CO²".
