Researchers say that springtime snow is melting in the Arctic even faster than Arctic ice. That means less sunlight is reflected off the surface. Bare land absorbs more solar energy, which can contribute to rising temperatures on Earth. Above, a musher races along the Iditarod in the Alaskan tundra in 2007.

This 2005 photo, released by the University of Alaska, Fairbanks, shows how snow-covered Alaskan tundra reflects more light than melted areas. Melting snows means the land can absorb and store more heat and solar energy.
Arctic sea ice is in sharp decline this year: Last week, scientists announced that it hit the lowest point ever measured, shattering the previous record.
But it turns out that's not the most dramatic change in the Arctic. A study by Canadian researchers finds that springtime snow is melting away even faster than Arctic ice. That also has profound implications for the Earth's climate.
Cecilia Bartoli has a passion for musical archaeology: "I am the Indiana Jones of classical," she says jokingly to All Things Considered host Robert Siegel.
Bartoli rummages through music history to uncover forgotten opera composers deserving of her detailed and dramatic performances. Her new album, Mission, introduces her most recent "find," the late-17th-century Italian Agostino Steffani.
Each week, All Things Considered and Lenore Skenazy, author of the book and blog Free-Range Kids, bring you "Another Thing," an on-air puzzle to test your clever skills. We take a trend in the news and challenge you to help us satirize it with a song title, a movie name or something else wacky.
So six weeks to go before Election Day, but in-person early voting has already started in a handful of states. Many others will begin soon, and more and more of us are choosing to vote early. In Colorado, for example, where we just heard from Ari Shapiro, nearly 80 percent of votes were cast early in the 2008 presidential election.
Michael McDonald tracks these trends with the U.S. Elections Project at George Mason University and he joins me now. Welcome to the program.
