Ahhhh I am looking at your post and can't seem to find your answer anywhere. It was warmer in the 30's. It was MUCH warmer during the Medieval Warm period. It was much warmer during most of the Roman empire. It was MUCH MUCH warmer during the Juriassic and Triassic ages. You are extremely unscientific, not well read and lack any mere sliver of curiosity and basic common sense when it comes to earths climate history past and present. If you have, as you claim, answered this question before then why can't you refresh our collective memories? What are you afraid of?
