The End of Climate Change, by Jeffrey Sachs

Is the earth's future in our hands? Jeffrey Sachs says so in Time magazine (found via Globalisation and the Environment). But don't put much faith in his ideas.

He believes that there can be such thing as "safe levels" of CO2 in the atmosphere.

And he is unfair:

Now as China's CO2 output threatens more intense hurricanes and droughts in the U.S., the tables are turned, and we will certainly want China to control emissions.

And he is wrong:

A few degrees above normal can mean the difference between life and death, species survival and extinction. And a few actions on our part could make the difference between a healthy planet and one that falls into an environmental tailspin.
