Have you ever flown over land and looked out the window? I've flown from Brisbane to Perth here in Australia and theres hardly a single square mile of the land that hasn't been dramatically changed by humans. All of it has been cut into squares and leveled of its native vegetation and filled with things that we either find tasty, useful or both. Australia has a much smaller population than the US (22M v. 308M), but doesn't have dramatically less land (7.6M km^2 v. 9.8M km^2).

Its not *just* about emissions from tailpipes and smoke stacks, thats just part of it.


You can easily fly over nonpopulated areas of Australia, the US, China, Canada, etc. and see nothing forever. Regardless, you can also fly over the oceans (which cover 70% plus of the surface area of the Earth) and find no human existance. You can then also delve into the Earth itself, and find the volume under the surface area which has exponentially greater mass. One major volcanic eruption causes more expulsion to the atmosphere than most of the carbon output of humans over the course of decades.

Having said all of that, I am not a climatologist. But there sure seems to be a lot of snow this year...
