Island Press Field Notes

What comes to mind when you hear the words "natural resources?" Oil. Water. Nature. Nature? In fact, yes, nature is one of the big ones. Ecologists and economists have a name for the natural resources that nature provides: "ecosystem services." They've calculated that globally the dollar-value of those services could be $54 trillion annually in 1997 dollars--for comparison the Gross World Product for 2008 was around $62 trillion.

I admit it. In my heart of hearts, I'm hoping for the best. Those scenarios of climate change we see splashed across the newspapers and magazines include a wide range of possibilities, and I keep my fingers crossed that we'll end up closer to the best case. But just three weeks ago the best case got a lot worse. A group of climate scientists meeting in Copenhagen announced that sea level very likely is going to rise almost twice as much as we thought.

When you’re in the middle of a forest fire, trees exploding all around you, smoke burning your lungs, and fireballs dropping from the sky, it’s hard to think about much except getting out of there alive.  That’s kind of where we are with thinking about global warming nowadays—the direct impacts on people.  How many lose their homes when sea level rises?  What new diseases are going to make their way out of the tropics?  How many dollars will it take to cut carbon emissions?
