...fascinated by their psychologizing, the sort that usually characterizes soap-opera-fan chat rooms and sports blogs: "I know what I read in the papers, but what are they really like?" Actually, the personality differences between Democrats and Republicans are minimal, even if their opinions are sometimes polar opposites. They are all subspecies of "nerd." If pressed, I can only mumble about who seems to smoke more (Republicans) and who gives more tepid parties (Democrats). Of course, these are differences of style, not substance...
...concern that Atlantic cod will encroach in the east and compete with the smaller Arctic cod, which have thrived in frigid climates with their special proteins that prevent freezing of the blood. Meanwhile, the retracting ice makes it harder for ringed seals to find breeding grounds and for polar bears to hunt...
...That means food isn't always there even when the Inuit can travel. Wildlife may well be less adaptable to extreme changes than humans are. When polar bears can't find prey, there are few alternatives; the bears burn their own fat, releasing into their systems the contaminants stored there--pesticides and other industrial chemicals that accumulate in cool Arctic waters and build up in the food chain. Other animals are also in trouble. In February, in what should have been midwinter in the far north, Nunavut's capital city, Iqaluit, was a balmy 5*noneC and rainy. When...
...risk as melting permafrost pours mud into rivers, burying the gravel the fish need for spawning. Small animals such as bushy-tailed wood rats, alpine chipmunks and piņon mice are being chased upslope by rising temperatures, following the path of the fleeing trees. And with sea ice vanishing, polar bears--prodigious swimmers but not inexhaustible ones--are starting to turn up drowned. "There will be no polar ice by 2060," says Larry Schweiger, president of the National Wildlife Federation. "Somewhere along that path, the polar bear drops...
