Deutsche Bank put up a billboard in Madison Square Garden that allegedly displays almost real-time data on the amount of greenhouse gases in the atmosphere. And I, for one, can't read that number.

Kevin Parker, global head of Deutsche Bank's Asset Management division, said of the counter at its unveiling: "It will be a huge task to bring global emissions under control and my hope is that putting this data in public view will spur both governments and markets to move us more quickly to a low-carbon economy."

The counter increases at around 800 tons a second, which, if you are good at the maths, you know translates into, um, a lot per day. At least half of which is my roommate. Seriously, dude's so gassy the walls in his bedroom are turning brown.
