President Trump's battle with the coronavirus could take him out of action for several weeks, raising concerns that U.S. adversaries such as Iran or China may become emboldened by the perception of an American leadership vacuum.

On Nov. 4, the day after the election, the United States will officially exit the 2015 Paris climate agreement.

The date is a coincidence. Still, the timing underscores a crucial victory for the Trump administration in its efforts to derail federal action on global warming, which the president dismisses as a hoax.

In April 2018, Tianna Spears joined the State Department, looking forward to the promise of a fulfilling career. Then 26, she had spent three years learning Spanish in the Dominican Republic and Spain to help land a position in the Foreign Service.

"I was super-excited to start," she says. "I had dreams of being a diplomat and living in several places in Latin America."

At least once a week, the Port of Los Angeles launches a drone over its expansive facility. It gives port officials a good vantage point to check on the 7,500 acres and 43 miles of waterway that make up the busiest container port in North America.

Earlier this month, the port's executive director, Gene Seroka, displayed photos from a recent drone flight showing stacks of cargo containers on the docks.

Consumer goods are arriving from China and elsewhere, but a lot is not getting to its destination.

A flotilla of Saudi tankers loaded with crude oil has begun arriving on the U.S. Gulf Coast, worrying American shale producers who face uncertainty because of an oversupply of oil.

At least 18 very large crude carriers, each carrying 2 million barrels of oil, are headed to the U.S., according to Michelle Wiese Bockmann, markets editor and oil analyst for Lloyd's List, a shipping news service in London.

The scale of oil market turbulence is on stark display along the California coast. About three dozen massive oil tankers are anchored from Los Angeles and Long Beach up to San Francisco Bay, turning into floating storage for crude oil that is in short demand because of the coronavirus.

Scientists are still trying to determine the origin of the coronavirus, but the predominant theory is that it began in a food market in Wuhan, China.

So-called "wet markets" — usually a jumble of stalls carrying produce, seafood, some farmed meat — are found across China, as well as in many other parts of the world. The problem is that these wet markets sometimes also carry live animals — occasionally including illegal, sometimes exotic, wildlife — bought and slaughtered on the spot, increasing chances for the spread of disease.

Iran is dealing with one of the worst outbreaks of the coronavirus in the world, with a death toll surpassing 2,200 people. But getting help into the country is hindered both by a truculent Iranian leadership and strong U.S. sanctions.

As of Friday, China had reported more than 55,500 confirmed cases of coronavirus and more than 1,300 deaths from the virus. In countries around the world, there are now at least 366 cases, including 15 confirmed in the U.S.

Airlines, cruise ships and high-end hotels worldwide are bracing for a sharp downturn in business because of the fast-spreading strain of coronavirus.

Looking out across a foggy harbor toward a peninsula jutting off the Norwegian coast, Rune Rafaelsen has a bold plan that could raise the profile of his remote Arctic town — with a little help, he hopes, from China.

He is the mayor of Sor-Varanger, a municipality in the far northeast corner of Norway, close to the Russian border. His office is in the small town Kirkenes — population a little over 3,500 — which overlooks the icy gray Barents Sea.

Since 2017, the Trump administration has placed layers of tough sanctions on Iran in an effort to deprive the regime of financial resources and to force it to negotiate a new nuclear deal.

The U.S. killing of senior Iranian military commander Maj. Gen. Qassem Soleimani left many of America's allies in the Middle East confused and nervous. That includes Saudi Arabia, the top regional rival of Iran.

The Saudi-U.S. relationship has become particularly close since President Trump took office. It could prove to be a double-edged sword for the kingdom, analysts say, as Iran contemplates its next moves. Iran and Saudi Arabia have long battled for regional dominance, and the U.S. has supported the Saudi-led war in Yemen against Iran-backed Houthi forces.

The U.S. killing of a top Iranian military leader, Qassem Soleimani, in an airstrike in Baghdad this week has raised thorny legal questions. Experts disagree over whether the U.S. had the legal authority to launch the deadly strike.

President Trump stated that Soleimani was plotting "imminent and sinister attacks on American diplomats and American personnel, but we caught him in the act and terminated him."

On a pitch-perfect autumn afternoon, a remote sheep farm in southern Greenland is quiet. The only movement is from a little girl playing outside her house with a fluffy border collie puppy.

The silence is abruptly broken when dozens of sheep come thundering across the hills overlooking the farm. Shooing them along is the girl's grandfather, Lars Nielsen, and her dad, 37-year-old Kunuk Nielsen.
