Climate Scientists feel that the reason for the HEAT increase (Global Warming) is that excessive world CO2 allowed a high altitude layer to block the infrared wave energy from the sun that then hit the Earth and bounced upward. 30 or so years ago the layer had not yet formed and the infrared would continue into space. Today, the radiation is refracted back to earth and has caused Man-caused Global Warming.

So now we're up to 50 years from 30? OK, no problem----50 WHOLE YEARS out of the last 4.3 billion? Or I'll settle for all the 50-year periods for the last 4.5 million years of our CURRENT ICE AGE. (Yes, by definition, we are in an ICE AGE)
