I'm not a fan of the design myself, and I'm surprised how effective a good design is.
I think you can do better.
I'd also hope that you could offer more than just links to the articles.
Maybe take a note from HackerNews, I'm sure there is tons of discussion that goes on regarding the topics and articles as the issues are extraordinarily complex.
I think that would be a solid value add.
What I think you have failed to do (or failed to tell us) is why people would visit your site over say TreeHugger.com, or others (I'm sure they exist, but I'm not super enviro-guy, so I don't know them all).
I'm under the impression that drudge focuses on slightly out of mainstream news coverage, but I could be wrong.
No doubt there is a huge market for what you are linking too, but from what I see, you are not yet offering me enough reason to come to you as a source.
Just my 2 cents.
