And don't forget the question of how they know what was happening at the Poles prior to the 1930s which was when polar exploration really got going. And of course even then it was an occasional expedition and not permanent bases. As to your question what they use are untestable, "Computer Models" that are based on ice core samples (how do we know their readings are correct) that scientists of the same mind dig up!
