You'd think that crossing the Arctic would be less dangerous in the summer. But in fact, thin ice and a warming climate make it far more treacherous.

On 13 May, explorers Lonnie Dupre and Eric Larsen will leave on a four-month unsupported expedition across the Arctic Ocean. Enduring shifting sea ice, these explorers will attempt one of the toughest feats in history. This journey however, is more than a story about heroism and adventure. Using skis and canoes, the team will cross the ice from Cape Arctichesky, Siberia, through the North Pole and onto Ellesmere Island, Canada, to document the impacts of global warming and highlight the threat it presents -- not only to the region, but to our entire planet.

While you may not be able to join Lonnie and Eric, you can still do your part to stop global warming. Watch for global action alerts at Greenpeace USA's website covering the expedition.

You can also tell us your personal story on things you have done to fight global warming.
