I've seen some ignorance on both sides of this issue, but it gets tiresome when global warming/climate change advocates go on about it as if it invalidates the entire debate. Trying to claim that there are people that deny "climate change" is ridiculous as well. Hell, my grandfather once told me he thought weather trends moved in at least 20 year cycles, and that was just his observations after living more than 60 years. Everyone knows climates shift around.
The simple fact is that the actual evidence of man-made global warming is weak or non-existent and all the predictions that have been made by scientists and supporters alike have not happened so far. IMO, it has gotten to the point that most of the researchers are just trying to keep the grant money rolling in and don't care a bit about whether or not it is a real issue.
