Katie Couric's Notebook: Going Green

Hi, everyone.

According to scientists, 2007 could well be the hottest year ever measured --caused, in part, by record amounts of greenhouse gas pollution.

Britain's Meteorological Office says that this is more evidence that global warming is happening, and that countries need to take action. But what about individuals?

Here are some easy ways that all of us can go green, with some help from climatecrisis.org.

Replace your incandescent bulbs with flourescents, which use 60% less energy.

Lower your thermostat 2 degrees in winter, and raise it 2 degrees in summer, eliminating 2000 pounds of greenhouse gas a year.

Cleaning filters on your air conditioner could save 350 pounds of the CO2 that causes global warming.

It's easy to think we can't make a difference. But all of us can -- even if it's just a matter of degrees.

That's a page from my notebook.
