During our recent discussion of climate change, someone linked me to this New York Magazine piece making the case for doomism.

I disagree with it pretty intensely, but most of my complaints are already listed in the sidebar (some scientists also complained, so they had to add a lot of sidebar caveats in) and I don't want to belabor them.

The section I find interesting is the one called Climate Plagues:

There are now, trapped in Arctic ice, diseases that have not circulated in the air for millions of years — in some cases, since before humans were around to encounter them. Which means our immune systems would have no idea how to fight back when those prehistoric plagues emerge from the ice.

The Arctic also stores terrifying bugs from more recent times. In Alaska, already, researchers have discovered remnants of the 1918 flu. They actually extracted it from the cadaver of a frozen woman. that infected as many as 500 million and killed as many as 100 million — about 5 percent of the world's population and almost six times as many as had died in the world war for which the pandemic served as a kind of gruesome capstone. As the BBC reported in May, scientists suspect smallpox and the bubonic plague are trapped in Siberian ice, too — an abridged history of devastating human sickness, left out like egg salad in the Arctic sun.

Experts caution that many of these organisms won't actually survive the thaw and point to the fastidious lab conditions under which they have already reanimated several of them - the 32,000 year old "extremophile" bacteria revived in 2005, an 8 million-year-old bug brought back to life in 2007, the 3.5 million-year-old one that a Russian scientist self-injected just out of curiosity - to suggest that those are necessary conditions for the return of such ancient plagues. But already last year, a boy was killed and 20 others infected by anthrax released when retreating permafrost exposed the frozen carcass of a reindeer killed by the bacteria at least 75 years earlier; 2,000 present-day reindeer were infected too, carrying and spreading the disease beyond the tundra.
