What global warming? We haven't even seen a single degree change in the 20th century. in fact it's cooler now than it was in the 16th century by about 5 degrees.
Climatologists have never, and still don't have a clue about the weather. They can't predict tomorrows weather, never mind weather next week, next year, 10 years or 100 years from now.
AGW is bunk, but the 16th century was actually damn cold. It was the Maunder minimum and the Thames froze over.
The important thing to remember is that we are a few degrees C colder than the Medieval Warm Period c. 1100.
