I believe that our warming sea waters,our changing sea current flows,and our sun has more to do with global warming than man made emissions. In the link below below,there is now evidence that a undersea volcano erupted in 1999 near the artic and still could be erupting.This is a good sign that the water is melting the artic,and along with co2 the natural warming trend is hastened.I also believe that western antartica melting is from an undersea volcano and evidence will be found in near future if not already known.What do you think about this,Chris??
