The astronaut speaks

Former astronaut Harrison Schmitt is one anthropogenic global warming skeptic.  He will speak in next month's International Conference on Climate Change in New York.  It is not that he is a former US senator (although not presidential candidate) that makes him justified to speak about climate change and global warming.  Mr Schmitt:

has a science degree from the California Institute of Technology. He also studied geology at the University of Oslo in Norway and took a doctorate in geology from Harvard University in 1964.

Schmitt had earlier resigned from the Planetary Society after the society took the stand that many groups have taken with regard to global warming.  He said that:

"global warming scare is being used as a political tool to increase government control over American lives, incomes and decision making."

AP, as it appears in the Boston Herald, writes:

Schmitt said historical documents indicate average temperatures have risen by 1 degree per century since around 1400 A.D., and the rise in carbon dioxide is because of the temperature rise.

Schmitt also said geological evidence indicates changes in sea level have been going on for thousands of years. He said smaller changes are related to changes in the elevation of land masses — for example, the Great Lakes are rising because the earth’s crust is rebounding from being depressed by glaciers.
