Can any one person make a meaningful difference in a crisis as sprawling and complex as global warming? Sure, if they join forces with hundreds of thousands – and soon millions – of others. That's the message of StopGlobalWarming.org, a website that houses the fast-growing virtual march against climate change. It educates marchers daily about the impact of climate change on our communities, and sends a message to Washington that America wants a federal response to this growing threat.

The site now boasts a quarter million marchers, including Leonardo DiCaprio, Arnold Schwarzenegger and Hillary Clinton among them. A quick and meaningful new year's resolution for all of us would be to join this worthy fight, and invite your friends and family to do the same. It takes 5 minutes and could make a world – literally – of difference.

Stopglobalwarming.org also offers helpful daily hints about how changing your habits can lower your planet-warming emissions. A sampling: Buy products made locally – it reduces the amount of energy required to transport the merchandize to your store. Reduce garbage – producing 25 percent less garbage will reduce carbon dioxide emissions by 1,000 pounds per year. Recycle paper, plastics and glass – you can save 2,400 pounds of carbon dioxide per year by recycling half of household generated waste. Recycled paper saves trees, which absorb carbon dioxide.
