Blog Action Day

This year's Blog Action Day is devoted to the theme of Climate Change and an understanding of mathematics is certainly essential for anyone involved in making making decisions about how to respond to this issue (which in a democracy is presumably all of us).

The choice of Math and Climate as the theme of this year's Math Awareness Month emphasized this connection, and Murray Bourne at squareCircleZ  today points to a number of articles in which he has used related topics as a source of examples for teaching mathematics.

A good source of background on the science of CO2 related climate change is this excellent history prepared by Spencer Weart at the American Institute of Physics, as is also the RealClimate site managed by a team of well-reputed climate scientists, and the question of how to compare the effectiveness of different policy choices is addressed in this on-line book by UK physicist David McKay (reviewed by theRegister).

The fact that no amount of restraint or conservation can counterbalance the harmful effects of increasing population is not often noted in the CO2 debate so I was a bit disappointed that Murray did not include his discussion of that topic in his list.
