The commenter on spout off should really learn his facts. I've worked in the NOAA science area of atmospheric observation and most of the spouters who say they they are versed on the sciences are really lacking in knowledge. We had Ice sheets in our Country just 11,000 years ago, the water has risen as high as it's going to go. we have about 600 more years to go before a climate reversal. NOTHING you can do to stop it!
