Okay, it’s a rhetorical question now but historically it wasn’t the case. I’m no historian but the little I know tells me that it was at least around in 1492 when Columbus sailed the ocean blue and some of his crew thought they’d fall off the face of the earth. Later, Magellan made it all the way around the Earth essentially ‘proving’ what many at the time thought that the earth was in fact round. However, up until that point I’m sure there were still doubters. That’s how I see this whole ‘global warming’ argument and people who want to make a 60 degree November day in Chicago the cusp of their argument of ‘proof’ that global warming is true? I wonder if these people don’t have access to computers to see that in the 1950s it reached over 80 degrees on a balmy summer like day in November. The following year in that same month of November Chicago got 8 – 9 inches of snow on that same date. I don’t know if global warming is true but I know there are ‘facts’ on both sides and depending on whether you believe or not you will sway the facts to your side to ‘prove’ your case. That’s what you do in a debate of course, discount the other side but it doesn’t make it any less annoying for me the outside reader or viewer. The world we live in is constantly evolving – as far as what little I’ve read on the topic we’ve been through numerous ice ages and catastrophic volcanic eruptions and periods of intense heat. I’m 99% sure those times were all before we were poking holes in the ozone layer. So I guess you can chalk me up to a non-believer. I don’t have any science behind it and sure I’m probably naive and I don’t see what is plain as day to all those pounding the table for global warming but I do know the planet knows how to evolve and like everything else we’ve been through I think we will make it out of this just fine.
