I rarely find anything of value on NBC, but I found this article interesting. It shows how little we know about global climate systems and how the global warming debate often overlooks real scientific data. I always try to explain to people that I believe in global warming because it is scientifically proven that without a ~30% increase of earth's temperature due to greenhouse gasses in our atmosphere, the earth would be uninhabitable. Global warming is a naturally occurring phenomenon proved by science, however, the whole idea that humans are going to suddenly upset billions of years of naturally occurring climate cycles by releasing some carbon in the atmosphere is a bit of a jump for me. According to the climate models we should actually be on the cusp of a global cooling trend which this study among others may corroborate.
