* NASA climatologist James Hansen, recently arrested at an anti-mountaintop-mining demonstration in West Virginia, says we're almost too late to stop climate change. I wonder about that "almost."

* Nate Silver considers the legislative strategy at work in the upcoming Waxman-Markey vote.

* Mapping relationships in the X-Men Universe.

* An early Christmas present for my father? Corzine trails badly in New Jersey.

* Lots of talk lately about Robert Charles Wilson's anti-Singulatarian Julian Comstock: A Story of the 22nd Century. Here's an interview at io9 that takes up that angle, while Cory Doctorow highlights this blurb:

If Jules Verne had read Karl Marx, then sat down to write The Decline and Fall of the Roman Empire, he still wouldn't have matched the invention and exuberance of Robert Charles Wilson's Julian Comstock.

* Dancing plagues and mass hysteria. Via MeFi.

* How complexity leads to social collapse: some intriguing historical exploration from Paul Kedrosky. Also via MeFi.

* Roger Ebert explains how Bill O'Reilly works.

O'Reilly represents a worrisome attention shift in the minds of Americans. More and more of us are not interested in substance. The nation has cut back on reading. Most eighth graders can't read a newspaper. A sizable percentage of the population doesn't watch television news at all. They want entertainment, or "news" that is entertainment. Many of us grew up in the world where most people read a daily paper and watched network and local newscasts. "All news" radio stations and TV channels were undreamed-of. News was a destination, not a generic commodity. Journalists, the good ones anyway, had ethical standards.

In those days, if you quoted The New York Times, you were bringing an authority to the table. Now O'Reilly--O'Reilly!--advises viewers to cancel their subscriptions to a paper most of them may not have ever seen. In those days, if the wire services reported something, it probably happened. Today the wire services remain indispensable, but waste resources in producing celebrity info-nuggets that belong in trash magazines. Advertisers now seek readers they once thought of as shoplifters. If nuclear war breaks out, the average citizen of a Western democracy will be better informed about Brittny Spears than the causes of their death.

Discussion (where else?) at MeFi.

Exactly 20 years after warning America about global warming, a top NASA scientist said the situation has gotten so bad that the world's only hope is drastic action.

Burning fossil fuels like coal is the chief cause of man-made greenhouse gases. Hansen said the Earth's atmosphere has got to get back to a level of 350 parts of carbon dioxide per million. Last month, it was 10% higher: 386.7 parts per million.

Hansen said he'll testify on behalf of British protesters against new coal-fired power plants. Protesters have chained themselves to gates and equipment at sites of several proposed coal plants in England.

"The thing that I think is most important is to block coal-fired power plants," Hansen told the luncheon. "I'm not yet at the point of chaining myself but we somehow have to draw attention to this."

Frank Maisano, a spokesman for many U.S. utilities, including those trying to build new coal plants, said while Hansen has shown foresight as a scientist, his "stop them all approach is very simplistic" and shows that he is beyond his level of expertise.

The year of Hansen's original testimony was the world's hottest year on record. Since then, 14 years have been hotter, according to the National Oceanic and Atmospheric Administration.

Two decades later, Hansen spent his time on the question of whether it's too late to do anything about it. His answer: There's still time to stop the worst, but not much time.

"We see a tipping point occurring right before our eyes," Hansen told the AP before the luncheon. "The Arctic is the first tipping point and it's occurring exactly the way we said it would."

Hansen, echoing work by other scientists, said that in five to 10 years, the Arctic will be free of sea ice in the summer.

In more positive news, Honda is releasing a hydrogen-fuel-cell vehicle, while wind power is outpacing nuclear power 10-to-1, with China leading the pack.
