An Atlantic Ocean current that helps regulate the global climate has reached an 1,000-year low, according to two new studies in the journal Nature.

While scientists disagree about what's behind the sluggish ocean current, the shift could mean bad news for the climate. The Atlantic Meridional overturning circulation [AMOC] – often called the conveyor belt of the ocean – exchanges warm water from the equator with cold water in the Arctic.

Hundreds of thousands of students, teachers, parents and victims rallied in Washington, D.C., and across the country on Saturday to demand tougher gun control measures, part of a wave of political activism among students and others impacted by school shootings.

A new mega-dam being built by Ethiopia on the Nile River is threatening to spark a war over water and shift political influence in northeastern Africa.

Ethiopia sees the dam as the key to its economic future, but its neighbor to the north, Egypt, fears the dam could spell doom for its water supply, says BBC Africa correspondent Alastair Leithead. The Nile supplies nearly 85 percent of all water in Egypt, according to the Food and Agriculture Organization of the United Nations.

If you've been watching the Winter Games on TV, you may have noticed there's not a lot of snow in Pyeongchang. While the South Korean region is known for its frigid winters, major snowstorms are rare in February.

That's where Snow Making Inc. (SMI), comes in. The Michigan-based company has installed snow-making machines at seven Winter Olympics, including Pyeongchang.

If you've ever tried to catch an Uber on a rainy day during rush hour or after the ball drops on New Year's Eve, you're familiar with dynamic pricing. That's when the price of a ride costs more or less depending on the demand for drivers.

The pricing strategy has long been used by other sectors of the travel industry, such as airlines and hotels, to balance supply and demand, and last month, a luxury restaurant in London rolled out a similar model.

The death of a former major league baseball player in his native Venezuela this week is renewing concerns over the Latin American country's growing health crisis amid ongoing economic and political turmoil.

Coca-Cola introduced four new fruit-flavored versions of Diet Coke this week in an effort to entice former soda drinkers and LaCroix-guzzling seltzer lovers.

The new flavors — Feisty Cherry, Twisted Mango, Ginger Lime and Zesty Blood Orange — are sold in slimmer, redesigned cans. They were launched as part of the beverage company's endeavor to offset slumping Diet Coke sales, which have steadily declined since the height of soft-drink consumption in the mid-2000s.

Cape Town officials are tightening water restrictions amid claims the city could run out of water by April 21. After three years of intensive drought, officials say residents are bracing for "Day Zero," the day water could stop flowing.

South Africa's second-largest city would be the first major city in the developed world to run out of water, if residents do not heed new stricter water measures. The region is experiencing its worst drought in a century, which experts say has been exacerbated by climate change and in Cape Town, rapid population growth.

The Trump administration must decide by next week whether to impose tariffs on the imports of solar panel components.

Some U.S. manufacturers have complained that cheap imports are forcing them out of business, while domestic installers oppose tariffs because cheap, imported solar panels have driven the industry's recent growth.
