I think that there are a lot of people who want to believe in man-caused global warming, because it is the liberal way. Others may not entirely believe it, but it suits their agenda. And others are just hypocrites that don't want to go against what the intelligencia is pushing.
I tend to believe what I can see with my own eyes and what I see is nothing new. I've kept a weather record of my own particular area of this world for a long time and it confirms what my Grandfather told me many, many years ago. And that is that there is no particular trend, nor pattern for the climate--"it's just that some years are colder than others." This has been one of those years. Hopefully, next year we'll see some of that global warming.
