Now that every scientist who isn't part of the lunatic fringe agrees that human greenhouse gas emissions significantly alter the world's climate, the debate on Capitol Hill has shifted from science to policy. And that debate has proved even more complex than Congressional fights over the stimulus package, car company bailouts, and the decision to invade Iraq.

On Friday, the House of Representatives passed HR 2454, the American Clean Energy and Security Act of 2009, by a margin of 219 to 212, with three abstentions. The bill is the first legislative attempt to regulate carbon emissions, and the first bill to directly finger humans as the cause of climate change.

This Thursday marks twenty years since China's military ended the 1989 Tiananmen Square pro-democratic demonstrations by killing off hundreds of students, workers, and ordinary civilians. It's fitting, then, that in celebration of the anniversary, the government is once again curbing free speech. Censors have been at it for weeks, but now they've even begun cutting citizens off from Twitter, Flickr, Hotmail, and Microsoft's live.com.

After a year of alarm and hype, cybersecurity has finally made it to the top of the Obama administration's to-do list. President Obama, introducing a new report on U.S. cybersecurity in a speech on Friday, said cybersecurity represents "one of the most serious economic and national security challenges we face as a nation."

With their shapeless black robes and lined faces, the justices of the Supreme Court do not project a particularly cutting-edge image. And for the most part, that's not a problem. The judges concentrate primarily on cases related to either hot-button issues like torture and abortion, or cases dealing with the legal minutiae of how courts should properly function.

It's time to call your bookie, because the line on global warming is in. A new paper from MIT breaks down the odds of different outcomes from global warming, based on whether governments take action now or later. And if you're taking that action, bet on "government getting involved" to beat the spread, as last week an important climate change bill made it out committee in the House of Representatives.

"Absolutely." That's what Barack Obama told Barbara Walters last November when asked if he would make the White House more environmentally friendly. Of course, he wouldn't be the first.

While most of the science news media was focused on a certain bacon-flavored illness, Obama quietly unveiled his Council of Advisors on Science and Technology. And while this team has doesn't have the pure nerd power of Vice-President Gore's Action Rangers, it is still a pretty impressive line-up.

In his inaugural address, President Obama said: “We will restore science to its rightful place and wield technology's wonders to raise health care's quality and lower its costs. We will harness the sun and the winds and the soil to fuel our cars and run our factories. And we will transform our schools and colleges and universities to meet the demands of a new age.”
