The Heat Was On: Atmospheric CO2 Triggered a Global Warming Event 40 Million Years AgoIn a new study scientists used "paleothermometers" to gauge CO2 and temperatures that prevailed during a long-lived primordial global warming event, and found CO2 to be the culprit http://amplify.com/u/juaw Note in this article, the science leans toward acceptance of supposition and opinion in determining their conclusions. To me, the statement,"So the authors considered multiple scenarios to account for variations in nutrient availability, concluding that CO2 concentration increased by a factor of two to three during the MECO." says there are other considerations, but that choices have been made to accommodate the study. I dislike that tone of thought, yet the past has taught me to see 'science', as it were, in a more skeptical vein, and it continues through articles like this one.Also, the article's intent to bring news has a lack of footnotes for the reader. Laypeople, yes, ignorant, no. http://amplify.com/u/jue1
