[Each month, Heartland Institute Science Director Jay Lehr, Ph.D. presents evidence that mankind has no significant impact on the Earth’s climate.—Ed.]
The National Aeronautic and Space Agency (NASA) has determined Mars, Pluto, Jupiter, and the largest moon of Neptune warmed at the same time the Earth recently warmed.
Two hundred million years ago, when dinosaurs walked the Earth, the average carbon dioxide concentration in the atmosphere was 1800 ppm, five times higher than today.
All four major global temperature-tracking outlets (Hadley UK, NASA’s Goddard Institute for Space Studies, University of Alabama-Huntsville, and Remote Sensing Systems Santa Rosa) have released updated information showing in 2007 global cooling ranged from 0.65 degrees C to 0.75 degrees C, a value large enough to erase nearly all the global warming recorded over the past 100 years. This occurred in a single year.
