In general, I have been critical of media coverage of global warming. So I am pleased to announce that two of the best environmental journalists working have launched blogs:

• A new environmental blog from Mark Hertsgaard, the terrific environment correspondent for The Nation (and author of a lot of great books).

• A new sustainability blog from The New York Times, dotearth, led by their first-rate climate reporter, Andrew Revkin. Revkin notes the limits of the traditional media on these issues:

I’ve decided to focus Dot Earth on the broad-brush theme of sustainability for a few reasons. One is that “slow drip” issues are hard to capture and convey through traditional media tools, which are mostly (and appropriately) focused on dramatic events happening now, not eventually momentous trends that hide in plain sight.

Another is that some of the underlying problems related to humanity’s impact on the environment are largely irreversible. The greenhouse effect appears a lot easier to amplify than to reduce. Extinction is forever (at least for now). Such issues deserve sustained attention.
