A term which really means "warming of the northern hemisphere" since the southern hemisphere is cooling. And during the 1970's, when the media was hyping an ice age, it really was an ice age of the northern hemisphere, since the southern hemisphere was getting much warmer in the 70's. It seems the whole problem is due to the fact that most people live in the northern hemisphere so whatever that hemisphere does, they call it "global." Right now, arctic ice is melting and antacrtic ice is growing. Mars does this all the time, sometimes it has a polar ice cap on the north, and sometimes on the south. Earth does the same thing, but idiots like Al Gore don't know this.
