2) How do the alarmists adequately explain past warming and cooling cycles that started long before the introduction of the first internal combustion engine? There was a Medieval Warm Period from 900-1300 and then a Little Ice Age from about 1500-1800. By simply looking at the covers of our most popular periodicals over the past century, these cycles are clearly evident. We worried about a coming Ice Age from 1895 to 1930, then it was the threat of global warming from the 1930s to the 1960s, followed by another imminent Ice Age during the 1970s, and now we’re back to the threat of global warming again. Our great grandkids will likely have to worry about another Ice Age. There’s just no such thing as our planet’s “ideal temperature.” Average surface temperatures are constantly in flux, up or down about a few tenths of a degree every year. These cycles are normal.
3) If man is solely responsible for the increased levels of CO2, then how do you explain the Ordovician Period, 440 million years ago, when the CO2 level was 16 times higher than today? Or, the Cretaceous Period, 140 million years ago, when dinosaurs ruled the Earth and CO2 was 8 times higher? Or, the CO2 levels from 95 million years ago which were about the same as levels today? How can these levels be changing long before the appearance of man?
Despite what they claim, no, the debate is not over. Not by a long shot.
But, it has never really been about the science anyway. It was, has been, and continues to be all about the money. Who needs to pay it, who collects it; who redistributes it.
Put it this way. Al Gore views capitalism the same way other liberals view tobacco. He doesn’t want to outlaw it, he just wants to tax it. He doesn’t want to kill the Golden Goose, he just wants more of the eggs for himself and his big government cause.
But that’s a topic for another column.
