Climate change is getting worse, and we might not be able to stop it

There's a new scary climate change report out today. The gist: Climate change is getting worse, it's our fault, and some of it is irreversible. The report says that if carbon dioxide and other greenhouse gases continue to be emitted at the current rate, it's likely that by 2100, temperatures could be about 6.7 degrees warmer. Though it wouldn't occur for hundreds of years, the huge sheet of ice over Greenland could melt entirely, leading to as much as a 23-foot rise in world ocean levels, leaving many coastal cities underwater.

Audio recording reveals pause that may be a new clue in Michael Brown's shooting

We're not sure if it's real yet, but an audio recording released Tuesday morning may shed light on Michael Brown's death. The tape, which was given to CNN, allegedly contains audio captured during a Ferguson resident's video chat at the time of the shooting. CNN says the authenticity of the tape hasn't been verified, but what appears to be gunfire can be heard in the background of the call. As many as 10 shot-like sounds can be heard. Several shots are fired in what appears to be fairly quick succession. There is a brief pause, then more shots are fired. An autopsy concluded that Brown, 18, was shot six times, with two fatal shots to the head.

American extremist Douglas McAuthur McCain dies fighting for Islamic State

Douglas McAuthur McCain, 33, of San Diego, was reportedly killed over the weekend fighting for the Islamic State. The State Department said it couldn't confirm the death. CNN, however, reported that McCain's uncle, Ken McCain, said the State Department informed the family Monday of McCain's death. Ken McCain told CNN the family was "devastated" and "just as surprised as the country" to learn of his nephew's participation with IS. Ken McCain said his nephew converted from Christianity to Islam several years ago. There are posters on McCain's Facebook photo page with a Muslim theme, including an "I (heart) Allah." Another is called "Soldiers of Allah" and shows what appear to be desert warriors striding toward the light under the headline, "They are coming back."

Flight diverted after man torments woman with device that won't let her seat recline

It was a full-scale mid-air meltdown over leg room. During a United Airlines flight from Newark to Denver, a man seated in the Economy Plus section, which offers four more inches of leg room than other coach seats, was using a $21.95 gadget called a Knee Defender to stop the woman seated in front of him from reclining her seat. A flight attendant asked the man to remove the device. He refused. Then things got heated. The woman who couldn't recline her seat got so mad that she threw a cup of water at the Knee Defender user. No one was arrested. The Federal Aviation Administration doesn't prohibit the use of the Knee Defender, but United Airlines, like most other major U.S. airlines, doesn't allow devices that prevent seats from reclining. USA TODAY's editorial board weighed in on the fight.

Burger King's merger with Tim Hortons spurs #BoycottBurgerKing

Burger King is ruling a larger fast-food kingdom, and some of its subjects aren't happy. The U.S.-based restaurant chain announced Tuesday that it agreed to merge with the Canada-based Tim Hortons restaurant chain. The $11 billion deal will create the world's third-largest quick-service restaurant company. The new global company will be headquartered in Canada, which could allow Burger King (BKW) to reduce its U.S. tax bill. The merger quickly was lumped into the growing public outcry over tax inversions, which allow U.S. companies to lower their tax bills by reincorporating in a country with lower corporate tax rates through a merger with a foreign firm. Several thousand comments flooded Burger King's Facebook page Tuesday. On Twitter, #TimHortons was a trending topic with #BoycottBurgerKing.

Hadley Malcolm talks with Mike Snider about the details behind Burger King’s merger with Canadian chain Tim Hortons.

Border crossings are reopening as part of Gaza cease-fire

Truce? After a seven-week war that has left more than 2,200 dead, Israel and Hamas accepted an Egyptian-brokered cease-fire Tuesday. This time, there's no time limit. Residents in Gaza celebrated with gunfire and chants. The cease-fire includes an agreement to open border crossings between Gaza and Israel to allow the flow of humanitarian relief, assistance and materials for reconstruction in Gaza. Palestinians will also be allowed to fish in an area up to six miles off the Gaza coast into the Mediterranean, up from three miles. Both sides are going to keep up indirect talks in Egypt to hash out other concerns, like building a seaport and airport in Gaza, and Israel's demand that Hamas disarm.

State Department spokeswoman Jen Psaki said the U.S. "strongly supported" the cease-fire agreement and asked all sides to comply with their terms after other cease-fires had broken down. (Aug. 26) AP
