I try to avoid discussions about climate change. It’s one of several topics I try not to discuss. I’m compiling a list.
I don’t discuss climate change because people are very touchy on the subject and I find some of their claims to be a little puzzling. Let me give you an example. According to climatologists, CO2 levels haven’t been this high in over 400,000 years. That certainly sounds scary. But 400,000 years ago, we were in the middle of an ice age. Despite record levels of CO2, the planet was buried under ice. What happened to all that global warming CO2 is supposed to cause?
And where did those record levels of CO2 come from, 400,000 years ago? Did the Mammoths and Mastodons drive SUVs? Did they heat their apartments with coal? I’m not a paleontologist, but I suspect they didn’t.
My guess is that the sun caused ocean temperatures to rise and the oceans released huge amounts of dissolved CO2 into the atmosphere. But if this is correct, it means that global warming came first. The rise in CO2 didn’t cause global warming; it resulted from it. This also explains how we could have record levels of atmospheric CO2 in the middle of an ice age.
So now whenever I hear someone say that CO2 levels haven’t been this high in 400,000 years and CO2 is going to melt the polar ice caps and drown us all, I think of those Mastodons, freezing in the snow, waiting hundreds of thousands of years for greenhouse gases to melt the ice so that they can finally take a bath.
