See The World’s New, To-The-Second, Green House Gas Tracker
In New York City there is a large digital display that tracks the national debt to the second. Building on that idea Deutche Bank has recently erected a similar display that tracks how many metric tons of green house gas are piling up in the atmosphere with each passing second. Over 3.6 trillion!
The display is on a big screen in NYC but it is also on-line for you to check out — but be ready — it is pretty startling. See the tracker here.
