Temperature and CO2 History

600 Million Year History Fig. 1A. TOP: Global Temperature and Atmospheric CO2 over Geologic Time. Late Carboniferous to Early Permian time (315 mya — 270 mya) is the only time period in the last 600 million years when both atmospheric…

Dominating Role Of Oceans In Climate Change

by Harrison Schmitt See Related Releases of February 22, July 2, 14, 19, and 24, 2010 The scientific rationale behind the Environmental Protection Agency’s proposed massive intrusion into American life in the name of fighting climate change has no scientific…

The Role of Greenland and Antarctic Ice Cores in Climate Science

by Harrison Schmitt See Related Releases of February 22, July 2, 14, and 19, 2010. Analysis of ice cores from Antarctica and Greenland play an important role in understanding the history of global temperatures and atmospheric concentrations of carbon dioxide,…

Global Atmospheric Carbon Dioxide

by Harrison Schmitt See Related Releases of February 22, July 2, and 14 2010. Given how little we actually know about climate, and particular the bogeyman called “carbon dioxide,” the President, the Environmental Protection Agency, Congress, and some ideological State…

Global Temperature In Climate Change

by Harrison Schmitt Ten thousand years of natural, post-Ice Age climate variability should give pause to those who maintain that current slow global warming and carbon dioxide increases result largely from human use of fossil fuels. Public confidence in that…

The Central Role Of The Sun In Climate Change

by Harrison Schmitt Policy makers at the head of government in the United States and elsewhere apparently want to believe, and to have others believe, that human use of fossil fuels accelerates global warming.  They pursue this quest in order…

Temperature and CO2 History

by Dr. Ed Berry Temperatures Let us look at temperatures. Here is a plot of the reconstructed temperatures and CO2 concentrations for the past 600 million years. We observe that CO2 is near its lowest concentration for the past 600…

Segalstad: Correct Timing is Everything – Also for CO2 in the Air

by Tom V. Segalstad, CO2Science In a paper recently published in the international peer-reviewed journal Energy & Fuels, Dr. Robert H. Essenhigh (2009), Professor of Energy Conversion at The Ohio State University, addresses the residence time (RT) of anthropogenic CO2…

Human CO2 emissions are irrelevant

by Dr. Ed Berry Tom Quirk shows natural variability of the climate is the prime cause of increasing CO2, not the emissions of CO2 from the use of fossil fuels. See: Energy & Environment, 20, 1-2, Jan 2009, pp 105-121…
