* Stephen Colbert to guest-edit Newsweek. That's just weird.

* Yesterday marked the first night in my life where I had any real desire to see The Tonight Show; the Daily Beast has a few highlights. For my part I thought Conan did pretty good, despite some jackass fans who demonstrated that adoration and heckling meet again someplace on the other side.

* Anthony Stewart Head is still teasing a Ripper spinoff.

* 'No Lifeguard on Duty': empty and abandoned motel pools.

* 75% of Americans now convinced terrorists have superpowers. Advantage: idiocracy.

* Production design for Pixar's Up.

* Climate Debate Daily, from the good (if too conservative) folks who bring you Arts & Letters Daily, is the latest addition to the ecology section of my sidebar.

* And from way back in February: the top 50 eco blogs, as ranked by the Guardian.

* More from the the 55-mph wars: Nissan's new ECO pedal "presses back upward when it senses drivers are driving too quickly."

* 'Junk Mail Produces as Much CO2 as 7 States Combined.' Here's how to stop it.

* 'Prepare for global temperature rise of 4°C, warns top scientist.'

* Scientists predict that the disappearance of Arctic sea ice 'will lead to a large-scale transfer of shellfish, snails, and other animals from the Pacific Ocean to the Atlantic.'

* But will algal ethanol save us? Virgin Airlines says yes!
