Images released Tuesday show the extent of surface melt on Greenland's ice sheet on July 8 (left) and July 12 (right). Measurements from three satellites showed that on July 8, about 40 percent of the ice sheet had undergone thawing at or near the surface. By July 12, 97 percent of the ice sheet surface had thawed.
A pair of NASA satellite images taken just four days apart tells a potentially worrying story of melting ice in the polar summer.
The first, snapped from orbit on July 8, shows about 40 percent of the Greenland ice sheet shaded in pink or red to illustrate probable or confirmed surface melting. The second photo, taken on July 12, shows nearly the entire land mass — 97 percent — blotched in a red hue.
On the first day of competition in the 2012 Summer Olympics, the U.S. women's soccer team bounced back from an early deficit to beat France, 4-2. The game was a rematch for the two teams that met in last year's World Cup semifinals.
France jumped out to a 2-0 lead before the match was 15 minutes old, scoring on a breakaway run by Gaetane Thiney; moments later, a short-range shot found the back of the net after several U.S. players failed to clear the ball following a corner kick.
As drought and high temperatures continue to devastate much of the country's corn and soybean crops, the USDA reports that food prices will continue to rise at least into 2013. NPR senior business editor Marilyn Geewax and The Earth Policy Institute's Lester Brown discuss the rising cost of food.
Like many high school students, Thomas Martinez and Tamara Hardy dreamed of leaving for college and finding their futures away from home. But both grew up on a Navajo reservation and were torn, between those aspirations and their strong ties to their poverty-stricken community.
Martinez struggles to balance the needs of his family with plans to run track in college. Hardy wants to earn an engineering degree away from home, yet like many Native parents, her mother and father are reluctant to see her leave.
Last week, the Boy Scouts of America reaffirmed the longtime policy of excluding openly gay Scouts and a ban on openly gay and lesbian adults as leaders. The Supreme Court ruled that this private organization is within its rights to do so. While many praised the group for upholding its values, some who earned the badge of Eagle Scout decided to return those coveted badges in protest. We'd like to hear from Scouts in our audience.
