Global warming has been happening since the ending of the last ice age. Slowly, but rising none the less.



In 1870, the oceans were rising...there wasn't nearly the carbon released as there is now. Lots of coal was burned, it choked the cities, but compared to today...it was nothing.



It's BEEN getting warmer...we can't stop it...we're probably not helping...but this is just a profit making scheme.
