Mike, you are absolutely correct. Anyone who has any knowledge of climate change over the centuries must know just how cyclical short term temp. changes can be. Additionally, it seems that very few take into account the El Nino & La Nina variations in the Pacific ocean currents. We're having an El Nino climate this year & if record snows on the East Coast & down south aren't an indication of just how volatile the changes are with these 2 phenomena I don't know what else is.
