The U.S. Geological Survey released a report Wednesday predicting that there could be dire consequences if a major earthquake hits the second-largest fault in Northern California.

The USGS simulated a 7.0 magnitude earthquake on the Hayward Fault, which runs up and down the East Bay Area through Berkeley, Oakland, Hayward, Fremont and Milpitas. The results show that an earthquake of that scale could kill up to 800 people and cause more than $100 billion in total damage.

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.

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.

Lawmakers in the United Kingdom are debating a new tax on disposable cups in an effort to cut down on waste.

While the so-called "latte levy" is controversial, the goal is to replicate the success of Britain's tax on plastic bags; their use has declined by 80 percent since the tax was introduced in 2015. Proponents of the tax say it would encourage people to carry around their own reusable cups rather than use disposable ones, which in their current form are difficult to recycle.

Search and rescue efforts continue in Santa Barbara County, Calif., after deadly mudslides killed at least 17 people and destroyed dozens of homes.

Over 26 hours and across 39 time zones, the world is celebrating the end of 2017.

New Year's celebrations kicked off in Samoa, Christmas Island and New Zealand as those countries were the first where the clock struck midnight. Here in the U.S., many events are set to occur under heightened security, including in Las Vegas, which is still reeling from the deadliest mass shooting in the nation's modern history three months ago.

Author Peter Zheutlin never wanted a dog, let alone a rescue. He had always believed, as a lot of people do, that rescue dogs are damaged goods.

Now Zheutlin can't imagine life without a dog, and he's become so driven by the issue of stray dogs that he's written two books about it. He tells Here & Now's Lisa Mullins the number of stray dogs has "cascaded out of control" in some parts of the U.S.

In his more than four decades in the fashion industry, Alaia gained a reputation for going rogue; he refused to follow the calendar of international fashion weeks and released his collections only when he was ready. He rose to fame for his body-hugging designs that celebrated the female form.

The Palestinians threatened on Saturday to cease communication with the United States if the White House closes its diplomatic mission in Washington, D.C., lodging a potential thorn in President Trump's plans for Mideast peace.

The State Department says the office of the Palestine Liberation Organization must close under a little-known provision in U.S. law that forbids it from requesting Israelis be prosecuted for crimes against Palestinians. Trump may reverse the closure within 90 days if the Palestinians prove they are engaging in peace negotiations with the Israelis.

Tens of thousands of euphoric Zimbabweans marched through the country's capital on Saturday to celebrate what may be the near end of President Robert Mugabe's reign.
