Thorium deposits in North America (Credit:USGS)by Marcel WilliamsHumanity currently exist in a global energy economy that is dominated by fossil fuels. And the combustion of fossil fuels by our industrial civilization has created atmospheric conditions with an ever increasing CO2 (carbon dioxide) content. The carbon dioxide in the Earth's atmosphere is now higher than it has ever been in the history of the human species. In fact, it is higher than in the entire history of our genus, Homo, which first emerged in sub-Saharan Africa more than 2.5 million years ago.At approximately 400 parts per million, current CO2 levels in the Earth's atmosphere may be as high as they were during the Pliocene Epoch when sea levels may have been 10 to 40 meters higher than they are today. And as long as we continue to use fossil fuels, the CO2 content in the Earth's atmosphere is likely to reach levels not seen since the Earth was devoid of polar ice caps altogether which could eventually raise global sea levels above 60 meters. So thanks to the humongous energy needs of our modern civilization, future generations face the possibility of living in a much warmer world with substantially higher sea ...
