Harrison Schmitt of New Mexico is a dissenter when it comes to man-made climate change.
In 1972, he was one of the last men to walk on the moon as part of the Apollo 17 mission.
“I don’t think the human effect is significant compared to the natural effect,” Schmitt said. “Not that the planet hasn’t warmed. We know it has or we’d all still be in the Ice Age. But it has not reached a crisis proportion and, even among us skeptics, there’s disagreement about how much man has been responsible for that warming.”
Schmitt grew up in Silver City and now lives in Albuquerque. He 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.
Scientists “are being intimidated” if they disagree with the prevailing global warming theory, he said. “They’ve seen too many of their colleagues lose grant funding when they haven’t gone along with the so-called political consensus that we’re in a human-caused global warming.”
He is among 70 skeptics scheduled to speak next month at the International Conference on Climate Change in New York.
Dan Williams, with the Heartland Institute in Chicago, which is hosting the climate change conference, said he invited Schmitt after reading about his resignation from The Planetary Society, a nonprofit dedicated to space exploration.
Schmitt resigned after the group blamed global warming on human activity. In his resignation letter, the 74-year-old geologist argued that the "global warming scare is being used as a political tool to increase government control over American lives, incomes and decision making."
Schmitt said historical documents indicate average temperatures have risen by one degree per century since around the year 1400, and the rise in carbon dioxide is because of the temperature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.
Schmitt said he’s heartened that the upcoming conference is made up of scientists who haven’t been manipulated by politics.
Of the global warming debate, he said: "It’s one of the few times you’ve seen a sizable portion of scientists who ought to be objective take a political position and it’s coloring their objectivity."

Meanwhile, Belgium has just inaugurated a “zero emissions” science post in Antarctica to study climate change at a cost of €20 million.
