This video GOOD News: Climate Change Changes Climate Change - Video is rather silly in appearance, but the news in it is not. This is a rare example of a negative feedback loop in climate change - melting ice releases minerals which increase photosynthesis in plankton, thus absorbing CO2.

Unfortunately, much more common are examples of positive feedback loops, such as the melting of the permafrost in the tundra releasing vast quantities of methane, an extremely potent greenhouse gas. But my hope is that there are in fact myriad negative feedback loops that we either a) have not discovered yet, or b) have not been publicized.
I will continue to search for examples in advance of Global Blog Action Day (or whatever they call it)!!
