I thought it would be interesting to go searching for Earth facts and statistics to see just what our planet is all about. Here is what I was able to dig up. As always, I will be adding and updating stats as I find new ones, so be sure to stay tuned…

Please note that some of these global warming facts are easier to find than others. Many of these stats come from the governmental or scientific reports, but some are based on news reports and not necessarily official tallies. As always, all stats are linked to their source. Basically, this is the best I can find and I don’t guarantee anything to be 100% accurate.
