Climate alarmists are pushing a storyline this month that atmospheric carbon dioxide levels are higher now than at any time in the past 3 million years. The last time carbon dioxide levels were this high, “sea levels were as much as 65 feet higher than they are now, Greenland was mostly green and Antarctica had trees,” USA Today ominously warns . CNN, The Weather Channel, and many other media sources are making the same claims. In reality, the claims support the mountains of existing evidence that the Earth’s climate is not very sensitive to atmospheric Carbon Dioxide.

If CO2 is the primary driver of the earth’s climate, then the Earth’s climate should be just as warm now as it was the last time carbon dioxide levels were this high. Sea levels should be 65 feet higher than they are, Greenland should be mostly devoid of ice, and forests should be populating Antarctica. Yet none of these are the case. In fact, none of these are even close to being the case. Nor would they be close to occurring even if our recent warming continues for several more centuries. If CO2 drives climate change, why aren’t temperatures even close to as warm as they were when Carbon Dioxide levels were this high in the past?.........To Read More.....
