the ice caps have been melting for the last 10000 years ,they used to extend down to northern france ,then they receded back to southern Britain the ice was a mile thick , the English chanell and the north sea were dry land ,in fact the river Thames was a tributary of the Rhine ,our Celtic ancestors walked across from France ,as the Glaciers melted the area which is now the north sea started to fill until it broke over the straits of Dover and Calaise and turning us into an island ,any one who saw the time team special sinking Britain ,they showed you all the bones dredged from the north sea by Dutch trawlers ,some of the bones were from Rhino showing a much warmer period , Tony Robinson done a series on tv about a month ago about mans origins ,and it showed there of ice sheets going back and forth thousands of years before the last ice age ,as far as i am concerned that last climate change conference in Copenhagen was attended by a lot of hypocrites getting paid and having a free all expenses paid break at our expense
