Buckle up — climate change could make this a bumpy flight.

That's according to a newly published study by two British scientists who say increased levels of CO2 in the atmosphere will make "clear air turbulence" — which can't be easily spotted by pilots or satellites — more common over the North Atlantic. That means the potential for gut-wrenching flights between the U.S., Europe and points east.

Margaret Thatcher, the iconic former British prime minister, died Monday at age 87 after suffering a stroke. Although she was a towering presence on the world stage in the 1980s, often standing shoulder to shoulder with fellow conservative President Ronald Reagan, some people may have forgotten her contributions.

We decided to highlight five things you ought to know about her:

She helped break the glass ceiling in politics.

As an icon of the American conservative movement in the 1980s, it would have been difficult to find a more unlikely figure than Britain's Margaret Thatcher, who died Monday following a stroke.

Thatcher became prime minister in 1979, a full year and a half before Ronald Reagan became president. She hailed from a country seen as a hopeless bastion of socialism by conservatives, many of whom, like Reagan himself, were strongly invested in the idea of American exceptionalism.

The U.S. military is making no secret about a training flight by a pair of nuclear-capable B-2 stealth bombers from a base in the American Midwest to the Korean Peninsula — what's being described as an "extended deterrence mission."

The flight of the two radar-evading bombers "demonstrates the United States' ability to conduct long range, precision strikes quickly and at will," the United States Forces Korea said in a press release Thursday.

Jared Loughner, the gunman responsible for the 2011 rampage in Tuscon, Ariz., that killed six people and wounded Congresswoman Gabrielle Giffords and twelve others, acted erratically in the days leading to the shooting but was quiet and otherwise polite with officers after his arrest, according to newly released documents.

North Korea cut a hotline with South Korea on on Wednesday and told the United Nations that conditions were ripe for a "simmering nuclear war" on the peninsula.

"Upon authorization of the Foreign Ministry, the DPRK [North Korea] openly informs the U.N. Security Council that the Korean Peninsula now has the conditions for a simmering nuclear war," a statement read. "This is because of [provocative] moves by the U.S. and South Korean puppets."

The latest confrontation is with Vietnam over the mostly uninhabited Paracel Islands in the South China Sea. Hanoi has accused Beijing's forces of firing on a Vietnamese vessel engaged in fishing near the islands, which both sides claim.

Vietnam did not say if anyone was hurt in the incident that occurred last Wednesday, but it described the matter as "very serious."
