Understanding the Subtle Complexities of Global Warming


On August 8, 2007 there were 2.23 million square miles of ice in the Arctic.

By September 16th there were only 1.6 million square miles, a decline of 28% in only six weeks. This new level was far below the lowest low previously reached, which was 2.05 million square miles in 2005. How could such a huge change happen so quickly?

While most of us no longer question whether global warming is happening, few of us understand the intricate path it is likely to take as it unfolds. One of the most important and least understood aspects of this path is idea of the “feedback loop.”

This recent Op-ed piece from the New York Times, which Inkslinger posted about last week, does a wonderful job of explaining this idea. It’s something we all need to understand. If you haven’t had a chance to read it, I highly recommend taking a few moments to understand this crucial concept.
