Earth's climate has changed long before we were releasing CO2 into the atmosphere. Europe was far warmer in the Middle Ages. During the 17th and 18th centuries it was much colder. Further back in time the Earth was several degrees warmer, often these changes only took centuries or decades.
Here's some information to consider.
Reseachers at the Harvard-Smithonian Center For Astrophysics (CfA) concluded: We are not living either in the warmest years of the past Millennium nor in a time with the most extreme weather. CfA also stated that clear patterns did emerge showing that regions world wide experienced higher temperatures from 800AD to 1300AD and lower temperatures from 1300 to 1900.
There have be over 75 major temperature cycles in the past 4,500 years.
CO2 has gradually and continually increased since 1800, yet temperatures fell between 1940 and 1980, thus causing some scientist to believe we were heading to an "Ice Age".
A United Nation report said that Livestock are responsible for 18% of the greenhouse gases that cause Global Warming, that's more than Cars, Planes, and all other forms of tranporation combined.
Our current CO2 levels have been over 12 times higher in the past, and at a time when cars, factories, and power stations did not exist.
96.5% of all carbon dioxide emission are from natural scources.
Several studies over the years have indicated that CO2 levels rise as temperatures rise, but lags behind the warming by 800 to 1000 years.
We've all heard the reports on Glaciers melting, but if you dig deep enough you can find that a few are actually growing, while some are remaining the same. How can Glaciers become larger if the Earth is becoming warmer?
Just how accurate are these recorded temperatures? Here's why I'm asking for over 60 years the United States has used Surface Stations/Climate Monitoring Stations to record daily temperatures, there are over 1200 of these stations in operation today. When these stations were originaly setup, they were set in areas away from buildings, concrete, asphalt really anything that would cause inaccurate readings. Since then as cities and towns have expanded, they have built around these stations if you go to their web site www.surfacestations.org you can see that a lot of these units are sitting beside buildings, concrete walkways, parking lots, tennis courts one is sitting within 10 feet of barrel where trash is burned. While all of these 1200 stations are not like the ones listed above many are, and it makes me wonder just how accurate these readings are, you know it has to be hotter at the ones around asphalt, concrete and buildings. There is a group currently conducting site surveys of all 1200 stations with over 450 completed so far.
