You can't really say that there's no such thing as global climate. It's simply a fact that the earth can be regarded as a single system, and temperature readings from all over the earth can be averaged. And when we do that, and when we smooth out the year to year ups and downs by averaging over 25 year stretches, we see an upward drift.
