Greenhouse gas emissions are accelerating — The rise in atmospheric levels of carbon dioxide has gone from one part per million each year in the 1960s, to 1.5ppm in the 1980s, to 2ppm in 2000. Now emissions appear to have picked up even more sharply, with the latest numbers from the National Oceanic and Atmospheric Administration showing an increase of 2.4ppm last year. Overall levels are rapidly approaching 400ppm; an atmospheric concentration of 450ppm is widely held as a point of serious danger.

Russia looking into Internet censorship — While the Russian media is kept under tight control, Internet access in the country has so far remained unfettered. That may be set to change, as Ars Technica reports.

CNET and Yahoo to ink editorial / ad deal — Yahoo has agreed to run much of CNET’s content on its site, as well as selling remnant advertising from the company, according to Kara Swisher.

Another Twitter engineer flitters away — Lee Mighdoll, a VP of engineering and operations added to the Twitter team back in January, has left the company. That follows the departure of chief architect Blaine Cook, for reasons still not entirely clear. Twitter has come under a lot of criticism this past year for its downtime issues, perhaps having some heads roll will help shore things up. The company also may also be preparing to raise a new Series C round, according to Silicon Alley Insider.

Ooma lowers prices in bid to compete — Ooma, as you’ll recall, is a startup selling $400 units that allow people to make free calls, for life, over a broadband internet connection. Following a rumor from Valleywag that the company is struggling, it has rolled out a new scheme to sell units for $249, with an optional monthly service plan for “enhanced telephony services”.

Google’s $70M restaurant bill — Even for Google’s famous free lunch, somebody pays: The company itself. The bill comes to $70 million, according to the Silicon Alley Insider. My question: Who gets the tip?
