The Arctic is heating up faster than anyplace on Earth. And as it heats, the ice is growing thinner and melting faster. Scientists say that sometime this century, the Arctic Ocean could be free of ice during the summers. And that transition is likely to be chaotic.
Arctic sea ice has always seen dramatic swings. Every winter, the ocean is completely covered with ice. It starts to melt in the late spring, and by September about half that ice has melted away.
NCAA President Mark Emmert says he's willing to back up his tough talk on punishing rule-breakers — even using the "death penalty" as a deterrent.
With salacious allegations swirling around Miami's football program, and one week after Emmert joined with university presidents to discuss toughening sanctions against cheating schools, the NCAA's leader said he believed the infractions committee should make the harshest penalty an option.
President Obama's bus tour across the Midwest this week could probably be summed up this way: jobs vs. deficits. Americans are clamoring for action on both, but action on jobs might mean more spending, which is a toxic word in Washington, as well as for many small-business owners.
A Small-Business Owner's Struggle
Terry Frank and her husband own a shop that sells everything from sandwiches to desserts on the Oak Ridge Turnpike in Oak Ridge, Tenn.
More than 300,000 children in the Horn of Africa are severely malnourished "and in imminent risk of dying" because of drought and famine, the head of the U.N. children's agency said Friday.
The United Nations says that tens of thousands of people have died in Somalia, Kenya, Ethiopia and Djibouti — and the organization warns that the famine hasn't peaked. More than 12 million people in the region need food aid, according to the U.N.
"The crisis in the Horn of Africa is a human disaster becoming a human catastrophe," UNICEF Executive Director Anthony Lake told reporters.
Fire officials have elevated the fire danger rating to "high" for both Bridger-Teton National Forest and Grand Teton National Park.
Jackie Scaggs is a spokeswoman for Grand Teton National Park. She says one of the biggest factors for the rating comes from a drier-than-normal season.
"We definitely had a wet spring, and we had an wet, early summer through June, but July actually had less moisture, less precipitation than we normally do and we have continued that trend into August. So the heavy fuels in the forest are drier than normal for this time of year."
The Libyan rebels have been on the move this week.
In Gheryan, an important city south of the capital Tripoli, it seemed everyone was celebrating Friday. Women, children, young men, older men and even white-haired grandfathers.
They jumped into trucks and cars and flashed the victory sign to each other in an impromptu parade. The city, which straddles the main road south from Tripoli, was a garrison for Moammar Gadhafi's forces for the past six months. From Gheryan, the military would resupply forces for the frequent battles in the country's Western Mountains.
Libyan rebels say a close Moammar Gadhafi associate who was once the No. 2 top regime official has defected in another blow to the increasingly isolated Libyan leader.
Abdel Salam Jalloud helped Gadhafi stage the 1969 coup that propelled him to power and transformed Libya from a monarchy to a republic. He was Gadhafi's most trusted deputy for two decades but began to clash with the leader starting in the 1990s.
Over the past five months, the Syrian military has repeatedly used tanks and heavy weaponry on cities and towns that are centers of protest.
As has been the case most every Friday since March, demonstrators turned out in huge numbers after the midday prayers, and there was more violence. Activists said that Syrian security forces fired at protesters across the country, reportedly killing at least 20.
Assessing whether this Syrian strategy is working depends on who you ask — and what version of the military crackdown in Syria you accept.
