At present we have 350 parts per million (ppm) CO2 in our atmosphere. This constitutes 0.035 % of our atmospheric content or approximately 1/30th of a percent. Now it would take about 100 years more of industrial activity to get the CO2 content to 450 ppm. This would only lead to an atmospheric percentage increase of 0.01 % or 1/100th of a percent. Now it is understood that the presence of our atmosphere leads to the Earth being some 20 degrees Celsius warmer than would be the case if it wasn't there.
HOW THE HELL WOULD A 0.01% INCREASE IN ATMOSPHERIC CONTENT LEAD TO CATASTROPHIC TEMPERATURES???
