Metric tons-0-meter

Chilling in the freezing wind at the taxi stand outside Penn Station, I noticed a huge electronic billboard I'd never seen before:

CLIMATE CHANGE
3,650, 090, 820, 007 metric trillion
Greenhouse Gases in Our Atmosphere

The bright red numbers were constantly changing.

The billboard was installed last June to alert people to the global warming crisis.

Meanwhile, at 44th and Avenue of the Americas, another glaring electronic sign calculates the national debt.

Very scary!
