Another interesting perspective on "climate change" can come from Antarctica's history and plate tectonics.

Antarctica was once covered by 1,000s of square miles of dense hardwood forest. When it became isolated from it's separation from south America, a dominant circumpolar current formed around it. The current prevented warm air and water from flowing pole-ward (think of a force field). As a result, Antarctica began to cool and ice started to form. This promoted a positive feedback loop (run away effect) in which the more ice that formed, the more light (IR) was reflected back to space, causing it to cool further. Now that sea ice is melting, there is less surface area to reflect light and more ocean surface to absorb heat. So now, we have a positive feedback in the opposite direction. This is why polar regions are warming fast than other regions on Earth.

Now think about how "climate" would have "changed" when the Atlantic ocean didn't exist (Pangaea- Think Gulf Stream) or when India was not apart of the Eurasian continent. The rain shadow north of the Himalaya's has caused vast desert-land on what is known as the Tibet Plateau.
