A new billboard set up in NYC at the corner of 33rd street and seventh avenue tracks the number of greenhouse gases in the atmosphere worldwide. It was put up today and started at 3.6 trillion metric tons.
The new 70-foot billboard, which declares “Climate Change Affects Everyone,” borrowed the idea of a counter from the national debt clock as a simple but powerful way to highlight the growing dangers of global warming, said Kevin Parker, who heads one of the divisions of the Deutsche Bank, the sponsor of the sign.
Before the clock was even posted, the number was at an 800,000 year high.
