Man's impact on global warming is minimal - Morris Daily Herald

To the Editor,

When we have hot summer weather it is automatically attributed to those evil greenhouse gasses or more specifically to carbon dioxide, CO2, by politicians and the media. With the constant propaganda from the media and Hollywood, it has become common knowledge that the industrial emissions of CO2 are warming the earth.

The amount of CO2 in the atmosphere is less than .04 percent. To picture this small number, if Wrigley Field was filled with 40,000 people, 16 people would be the number of people making up the .04 percent. While CO2 is a greenhouse gas, its contribution to the global warming effect is only 20 percent, with water vapor contributing about 60 percent and other minor gases making up the difference. But the contributions of CO2 and other greenhouse gasses due to manmade causes is only 0.28 per cent of the total greenhouse effect. That means that 99.72 percent of the greenhouse effect gases are due to natural causes.

Reducing CO2 emissions of power plants and industry has a meaningless effect on the global warming from greenhouse gasses.

The truth is that the earth has been going through warming and cooling cycles for as long as a million years, well before man made factories put CO2 into the air. The last significant warming period was between 900 and 1300 AD, known as the Medieval Warm Period. This was followed by the Little Ice Age between 1400 and 1900 AD. (Yes, it really was cold at Valley Forge). So now the earth is again on a warming trend as part of the normal earth temperature cycle. Recent scientific studies have found correlations between solar cycles and global temperature cycles.

The point is that science may not have all the answers yet on global warming, but the facts clearly show that man has no significant control over global warming.
