Well, the climate experts have revealed that this year and decade have been the warmest on record. I remember back in the 1990s that just about every year was in the top ten warmest recorded. There are those who say it has all happened before, and they are correct. There have been brief periods in the past 1000 years when temperatures rose, but not as much as during the past few decades and not with the same accelerating tendency. However, before humans kept histories, the global temperature was, for extended periods, even higher than today. Unfortunately for religious zealots this occurred before they believe the earth was created, so they really can’t refer to it in their counter-arguments. For others, I believe it has been proven that the residents of those times, mastodons, dinosaurs and the like, all moved their cities inland.
