as to how cold in the winter adds up to evidence that there is no global warming? here's the deal- green house gases trap heat- hence the melting polar ice caps in both poles. melting ice cools the oceans and voila` also changes weather patterns and makes winters in some areas a wee colder. don't worry fred- one day we won't have those pesky polar ice floes melting to cause the colder winters.
also, i am not an expert, but when you have folks playing around with weather patterns- chinese and americans- that isn't great either.
