IMO, Global warming is a given! After all, approximately 75,000 years ago, the planet was 60%, covered with ice. Science tells us that NY was covered with ice, 1 mile deep! The earth has been warming ever since. However, Science also tells us that from approx. 1044 AD, until approx. 1288 AD, that we did suffer a severe draught, on this hemisphere that was responsible for the demise of at least 2 separate civilizations. The lose of the Ponderosa forests, lush grass lands and water ways of our SW, as well as the lose of 75% of our Sequoia forests.
This draught was followed by a mini ice age. Climate change will happen, in spite of man.
