I think a investigation needs be done, it puzzles me anyway, on how Global warming data can be kept on record... and can be of some sort, accurate.
My opinion is Global warming does exist among us but is uncontrollable. I think nothing can be done to stop the Polar ice caps from melting, sea levels rising ect.
As Technology improves over time, maybe we will find out that all this money spent on combating global warming has been a huge waste. Time will tell i suppose.
