The earth has a way of balancing itself...the ecosystem is self-containing within reason. I find it very interesting that back in the 80's when we were depleting the ozone layer via aerosol cfc's, and it was proven, no one doubted that it was caused by 'us' and our use of aerosols. Well, does it not stand to reason that temperatures can rise over a period of time...for any reason?

I mean, the sun is still the distance away as it has always been...and so is the moon along with the other planets.The sun isn't getting any 'hotter' because the sun will burn out after "X" amount of time which means it'll get cooler if anything...just sayin'. However, we're seeing drastic and record changes in weather patterns all over the globe, and, simultaneously at that. Ice has melted in places that there is normally an abundance of it...and it hasn't replenished elsewhere in that same amount. That's worth looking into in my my book.
