Um, dood, the media and laymen such as yourself are using things such as recent warm winters to claim evidence of global warming. Scientists are actually using more scientific evidence, such as core samples that show that we have not seem similar climate for thousands of years, which in fact is significant. There is abundant evidence. If you're going to bleat about the earth being flat^h^h^h^h not warming, at least look at the real evidence so you can refute it properly.
