Global Warming Primer - Facts

Sometimes it is hard to find the real facts to make up your own mind regarding items in the news. I ran across the following "Global Warming Primer" that displays the historical facts in graphical format for all to examine and make up their own minds.

I, for one, found the following interesting:

Greenhouse gases make up 1% - 2% of the atmosphere.

95% of that is water vapor, 5% is CO2 (.1% of the atmosphere).

96.6% of the CO2 is produced by nature, volcanoes, decaying plants, animal activity, etc. 3.4% is caused by humans where breathing is a major factor.

550 million years ago, the Cambrian Period, CO2 was 18 times greater than today. In the Jurassic Period, when Dinosaurs roamed the Earth, CO2 levels were 9 times higher than today.

Charts show, that over millions of years, there is no close relationship between CO2 levels and temperature.

When taking the last 400,000 years there appears to be some relationship between CO2 levels and temperature. But through the ups and downs of CO2 levels during that period, the Earth went through a number of Ice Ages.

During Roman and Medieval times, the Earth was warmer than it is today.

Today we are in a recovery period from, what they call, a Little Ice Age, that began in 1300 and ended in 1800.

The Earth's average temperature has risen less than 1 degree Celsius in the past 100 years, 1/2 of which happened before 1940, before greenhouse gases began to rise.

After seeing this, it is hard to see where all the panic is coming from. There must be a lot of money to be earned by Al Gore and friends. The attached pdf file gives you the facts to make up your own minds. Page 11 is particularly interesting. Global Warming Primer
