Global Warming?

Today I want to share my views on the issue of global warming. Now, its all well and good to think that we are so special and powerful that we can destroy the world with our chemicals and emissions, but lets get real here.

Once upon a time ago this planet was tropical and lush, and dinosaurs were at the top of the food chain, not humans. Then something happened to cause that tropical climate to change into an ice age, with large glaciers all over the place. Okay so now for comparison, imagine a pound of hamburger is the world. I stick that pound of hamburger in the freezer and it comes out a ball of ice. Leaving the ball of ice on the counter results in what? The gradual thawing of the hamburger. It happens slowly at first, but as more and more of it thaws, it speads up.

Given this comparison, does it not stand to reason that eventually our planet would thaw out?? I know this isn't exactly scientific jargon, but it seems like common sense to me that our planet would not support all that ice as it naturally returns to its former warmer state.

Anyway ... that is my deep thought for the day.
