A letter from a reader: Calculus and climate change

November 12, 2007:

While studying the Calculus at Princeton, I was introduced to the concept of a curved line approaching a vertical line asymptotically, that is, the approaching line gets ever closer to being vertical itself. An example of this is the world population curve, drawn over time. This was shown in the Al Gore film An Inconvenient Truth very briefly, unfortunately. It is my not-so-humble opinion that approaching the climate-change problem without considering this phenomenon is similar to rearranging the deck chairs on the Titanic.
