Global warming may have been a good thing in those days, but I don’t think they had a billion people living at sea level in those days. Also, at its height, water covered half of Florida. I am not saying GW is correct, I am merely pointing out that even a few feet of sea level rise would be devastating or at least dangerous to many millions, including those in New Orleans, Miami, New York, all our East Coast resort areas, and many along the Gulf, etc. I don’t know the West Coast, so make your own list.
Having been in the environmental business for 23 years I have been hearing about GW for many years, and the one thing you never hear from the DBM is that in all those years not one computer model has ever been correct. In fact when they go back and put in the actual facts for the years in question the models go totally to h**l. They also don’t tell you they do not include cloud cover, ocean temperatures or atmospheric concentrations of CO2 into their models, because there is no computer available that can interpolate that data over a long period. If you listen to the GW zealots you will notice they always use words like could, may, is expected, theoretically etc. They use those words because the historical facts do not support their past premises. There has never been a GW computer model that was accurate. That is why they have moved the model years to 50-100 years out. The facts are there has been no warming since 1998, 1998 was not the warmest year in the 20th century, 6 of the 10 warmest temperatures during the last 100 years occurred between, the late 20’s-mid 30’s, the last 3 years has been showing a slight cooling trend, 32,000 PhD, MS, BS hard scientists have signed a petition questioning the whole premise, I could go on, but I imagine you are getting the picture. If I owned ocean front property I wouldn’t be too worried, unless I didn’t enjoy cool breezes coming off the water.
