Hidden Brain host Shankar Vedantam takes you on vacation with him to Alaska. You'll hike on top of a glacier, drink from a cool stream, and talk with fellow tourists from around the world. But the trip comes with an upsetting observation: Glaciers in Alaska are retreating. The Mendenhall glacier, visited by tens of thousands of tourists each year, has receded more than a mile and a half in the last half century.

"It's sort of just collapsed in on itself," says John Neary, director of the Mendenhall Glacier Visitor Center.

Dozens of brew masters, water policy experts and engineers are gathering in Milwaukee this week to talk about the role water plays in beer making.

The 7th annual Great Lakes Water Conservation Conference kicks off Tuesday at Discovery World. Completely organized by volunteers, the two-day event moves from city to city around the Great Lakes Basin each year to keep the discussion going.

WUWM's Susan Bence caught up with a few of the volunteers to hear their perspectives on the role of the conference:

Outside Reno, in Nevada's high desert, Tesla is building what it says is the world's largest battery factory. The Gigafactory, as it's called, will churn out batteries for the company's electric cars. But it's also making something new — a battery for the home.

Tucked away in a dusty valley near Sparks, Nev., the Gigafactory is kind of like Willy Wonka's chocolate factory: It's mysterious, it's big and few people have been inside.

Actually, "big" may not do it justice.

Yellowstone National Park, a wilderness recreation area stretching for nearly 3,500 square miles atop a volcanic hot spot in Wyoming and parts of Montana and Idaho, may be in trouble.

Each year, Yellowstone attracts millions of visitors and provides a home to countless animal species, including the once-threatened grizzly bear and bison. But finding the right balance between tourism and preservation can be tricky.

Environmental activist Luis Jorge Rivera Herrera has worked to protect a pristine section of Puerto Rico's coastline. Now he's being honored with the Goldman Environmental Prize.

Twenty-four states are suing to block the Obama administration from implementing its new clean power regulations — the cornerstone of a promise that the United States will reduce greenhouse gas emissions to limit global warming. Those rules come out of the Paris Climate Accord, which Secretary of State John Kerry plans to sign on Friday.

Millions of years of Florida's history are lying on a table in Paulette McFadden's office at the University of Florida in Gainesville. It's in long metal tubes containing several feet of sediment from Horseshoe Beach, a community on Florida's Gulf coast.

"This core," McFadden says, "actually spans about 30 million years."

A solar-powered plane called the Solar Impulse 2 is preparing to resume its flight around the world after nine months on the ground for repairs.

The team's goal: to be the first plane to circumnavigate the globe using only solar power.

NPR's Geoff Brumfiel tells our Newscast unit that the plane is getting ready for liftoff in Hawaii. Here's more from Geoff:

Chicago's North Broadway Street is always bustling, but in the past few weeks, it has been noisier than ever. There is water flowing from an open fire hydrant, and as traffic inches by, a cement truck backs up and pours concrete down into a big hole in the street.

"Well, we always say there's two seasons: either winter and construction," says Maureen Martino, the executive director of the Lakeview East Chamber of Commerce. This water main upgrade is only the beginning; Martino says the city has plenty more scheduled for the area this year.

How Do We Get Our Drinking Water In The U.S.?

Apr 14, 2016

Before you take a gulp of water, try to mentally trace where that water that just gushed out of your taps has been: How did it go from that weird-tasting raindrop to the clear, odorless water that is sitting in your glass now?

Safe drinking water is a privilege Americans often take for granted — until a health crisis like the one in Flint, Mich., happens that makes us think about where it comes from and how we get it.

Springtime is usually beautiful in Mexico City. As the weather warms, the purple jacaranda trees that line boulevards and dot neighborhoods are in full bloom. Everything is prettier, says Fernando Padilla, a driver taking a break in a park.

"It's my favorite time of the year," he says.

But this spring, his eyes are watering, his throat hurts and one day a week he's not allowed to use his car on the road, which means he's poorer too.

Coastal cities across the globe are looking for ways to protect themselves from sea level rise and extreme weather. In the U.S., there is no set funding stream to help — leaving each city to figure out solutions for itself.

New Orleans and Philadelphia are two cities that face very similar challenges of flooding from rising tides. But they've chosen to pay for the solutions in very different ways.
