The Sierra Club has compiled an archive of all the journalism they've done in Sierra magazine on the Bush administration's environmental record. Shocking reading, certainly, but also deeply informative if you want anchor yourself in the political realities of the moment.
Great compilation of info. BushGreenwatch, http://www.bushgreenwatch.org, also puts out daily updates on Bush administration environmental policy. Disclaimer: I write for BGW. But I'm still knocked out anew every week at how much there is to write about.
