"NEW YORK -- Deutsche Bank lit a seven-storey-high sign in the middle of Manhattan on Thursday that counts the total amount of greenhouse gases trapped in the Earth's atmosphere.

The bank said it was the world's first sign to show real-time measurement of the gases blamed for global warming and hoped it would spark more public debate on how to reduce emissions.

The giant carbon counter developed by scientists at the Massachusetts Institute of Technology hangs outside Madison Square Garden."
