When I insist on others’ accepting facts regarding the temperature of the earth, I mostly limit that to the approximately 130 years for which we have decent worldwide temperature measurements. Those data are quite clear.
Regarding carbon dioxide, there is another molecule linked to human activity that may also contribute substantially to the warming: methane, which is produced by domestic livestock such as cattle. Did you see the recent New York Times article on the subject? Unfortunately, the alternative meat proposed, kangaroo, is not kosher.
