Global Warming: The Blog Epic

Thursday, January 22nd, 2009

What the heck does all the new data on global warming mean? For some perspective, take a look at one scientist’s very readable primer on climate change. Greg Laden, a biological anthropologist, provides not only good background but also cool facts. Here’s Laden on the major greenhouse gas:

Carbon Dioxide is a deadly poison. It is about 50% heavier than air, so where it occurs in density, in mines or certain natural vents associated with volcanics, it can accumulate in low spots. There are places in the Western Rift Valley where puddles of Carbon Dioxide form overnight while the air is still. These gas puddles can occur over puddles of water. When animals (such as antelopes) put their head down to the water to drink, they take a few whiffs of the gas and die. 

So far there are seven installments. You can find links to them here.
