It's a chilly February day as we set out from the Arkansas side of the Mississippi River. We're in a 24-foot cypress canoe, paddling south, with John Ruskey guiding in the stern.

The first stretch of journey, just south of Helena, Ark., is far from wild. We paddle past lots of industry lining the riverbanks: Along the shore, we see grain being pumped from a giant grain elevator into barges on the river. We pass coal and petrochemical docks, too, supplying or offloading the barges that ply this river up to Minnesota, and down to the Gulf of Mexico.

When it comes to climate change, we often think of the cars we drive and the energy we use in our homes and offices. They are after all, some of the biggest contributors to greenhouse gas emissions. But what about the toast you ate for breakfast this morning?

A new study published Monday in Nature Plants breaks down the environmental cost of producing a loaf of bread, from wheat field to bakery. It finds that the bulk of the associated greenhouse gas emissions come from just one of the many steps that go into making that loaf: farming.

Mahershala Ali won the Academy Award for best supporting actor for his role in Moonlight. NPR's Kelly McEvers spoke to Ali in October about his experience working on the film, which won the Oscar for best picture. This story originally aired on Oct. 21, 2016 on All Things Considered.

Trump said getting rid of the rule, which required oil, gas and mining companies to disclose overseas royalties and other payments, would bring back jobs and save extraction companies many hours of paperwork and, potentially, hundreds of millions of dollars.

A 19-year-old white man accused of kicking a coat hanger up the rectum of a mentally disabled black teammate received no jail time at his sentencing on Friday.

Former high school football player John R. K. Howard entered a so-called "Alford plea," meaning he maintains his innocence while admitting a judge or jury would likely find him guilty. He was sentenced to probation and community service, and his conviction might be entirely dismissed at a later date.

The Department of Justice is reversing the federal government's position in an important voting rights case, involving a Texas voter ID law. The switch was not unexpected following the election of Donald Trump and confirmation of Jeff Sessions as Attorney General.

In 1939, Nazi Germany started World War II and Adolf Hitler’s highly mechanized army began gobbling up territory across Europe.

As Hitler set his eyes on sacking Great Britain, Prime Minister Winston Churchill knew there was no chance of defeating him by conventional means. So Churchill created a top-secret organization devoted to sabotage and guerrilla warfare.
