Ok global warming is becoming a problem... with all of the polution in the air and so on... However is it as big a problem as Al Gore says? Yes polution is terrible,but will we all become like the planet Venes one day?
When Lief Erickson first discovered the New World long before Columbus, the Vikings descovered grapes growing in North America around Novia Scotia.therefore they called it Vinland. Many historians say they must have sailed further south, However England has records of citrus fruits being grown at that time in England..so we must conclude that there was a period of global warming at that time. Later in history there were accounts of global cooling and more global warming, like the seasons. In the 1980's scientist feared of a coming global ice age,but know they fear of a global warming greenhouse disaster. Polution may have increased the effects of this period of global warming, but it is just a period. Besides warmer tropical temperatures make plants grow= more oxygen.
