Points, sharp and dull: I did post from an advocacy site so that I could included the heart-warming pictures of harp seals (remember when that was a cause-celebre?). The news was being posted on a variety of sites, including MSNBC. I agree (and included this in my original post) that record keeping and causal analysis are both vital to this issue. Nonetheless, even if we agree that greenhouse gases are on the decline, we don't do enough, your SUV point being most cogent (we only drive eco-friendly Japanese brands that get over 28 mpg). Bring back the station-wagon! This one is particularly sweet (okay, the mileage ain't great, but this is about as extreme as you get - having driven one, I can attest).
