Scientific evidence from several independent sources now indicates that the global climate change that we see today is substantially due to the net increase in carbon dioxide levels caused by human activity. Mario asks: Santosh, What is your explanation for the number of reputable scientists who disagree that the global climate change we see today is being caused by human activity, as outlined in the following opposing report: http://epw.senate.gov/public/index.cfm?FuseAction=Minority.Blogs&ContentRecord_id=2674e64f-802a-23ad-490b-bd9faf4dcdb7&Issue_id= Can you also update us on: 1) what percentage of the total earth's atmosphere do MAN-MADE greenhouse gases represent as per the most recent estimates: a) water vapor, b) carbon dioxide, c) nitrous oxide and d) chlorofluorocarbons 2) what is the estimated growth in average CO2 levels since 1998? 3) what is the estimated growth in average global temperatures since 1998?
