Index of Subjects Ulli, I am not denying that global warming, a.k.a. climate change, is happening. My question is about the mechanism, i.e. the proximal cause, of one half of the Earth's Northern hemisphere having a record warm winter and the other a record cold winter this year. Any thoughts? A westward shift in the position of the Gulf Stream is a possibility..
