The heat is on

The cover story in the Economist magazine this week is global warming. The subhead says it all:

The uncertainty surrounding climate change argues for action, not inaction. America should lead the way.

Global warming, a serious environmental issue (perhaps the environmental issue of our time) is also a really nice way to link together the different subjects and lectures in Bio1B: Evolution; plants and ecology.

From the always entertaining Wikipedia:
In one episode of The Simpsons, Homer is travelling by air in first class and says "Look at me, I'm reading The Economist. Did you know Indonesia is at a crossroads?" Four days later, with its customary dry wit, The Economist alluded to the quote, and published an article about Indonesia referring to the "crossroads".
