New Yorkers now need only crane their necks for a reminder of the need for new energy practices in America.

Deutsche Bank recently unveiled a seven-story 'carbon clock' in Manhattan to keep a ton-by-ton tally of the amount of carbon dioxide being pumped into the atmosphere.

The counter, devised by MIT scientists, reflects the growing need for emission reform: the spinning numbers show that carbon is being added to the atmosphere at a rate of about 800 tons per second.
