The Mendenhall Glacier is visible from the visitor center parking lot. But it's still pretty far and if you traveled all the way to Juneau, Alaska, you probably want to get up close to the blue tinted ice.

Touching the face of the glacier can be tricky. You're separated by cold, silty water, and a hike over the ridge could take hours.

Visitor center staff know that. And inside, they use it to prove a point.

There was a time when Sandra Gologergen's freezer never ran out. Packed with traditional Inuit foods like whale, walrus, seal and fish, her freezer has been an essential lifeline, ensuring her husband, three kids and grandson make it through the long harsh winters of Savoonga, Alaska.

"Then that changed," she says.

Mesa Verde National Park in southwest Colorado is known for its iconic cliff dwellings, but archaeological artifacts left by the Ancestral Pueblo are all over. Rocky remnants of homes and farming sites are scattered throughout the dense pinyon juniper forest.

The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s.

Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops got higher.

A city in India has recorded the highest temperature in the country's history — 51 degrees Celsius, or 123.8 degrees Fahrenheit.

Murari Lal Thanvi told the BBC it was so hot in the city of Phalodi on Friday that his cellphone stopped working. "I was able to switch my mobile phone on after putting a wet cloth on it for about 20-25 minutes."

Scientists have long warned about the potential for the West Antarctic Ice Sheet to dump an incomprehensible amount of ice into the sea as global temperatures rise.

But their warnings were generally about a future hundreds of years away.

Now, a new report suggests that future could be much closer.  

An Upside To Climate Change? Better French Wine

Mar 21, 2016

While climate change threatens coastal cities and generates extreme weather, the effects of global warming could bring good news to some of France's most esteemed vineyards.

Here, the conditions needed to produce early-ripening fruit, which is historically associated with highly rated wines, have become more frequent, according to research published online Monday in the journal Nature Climate Change.

Canada and the U.S. have announced a cooperative plan to tackle climate change by cutting methane emissions from the oil and gas industry, investing in clean energy research and reducing future hydrofluorocarbon use.

At a joint press conference in the White House Rose Garden, Canadian Prime Minister Justin Trudeau and President Obama praised the strong ties between Canada and the U.S. They also announced plans to further facilitate trade between the two countries and expressed a shared commitment to protect the environment.

The National Oceanic and Atmospheric Administration says last month was the warmest January on record. That sets off alarm bells for climate scientists, but for the average person living in a northern climate, it might not sound so bad.

That's what many people are saying these days in Russia, where the expected icy winter has failed to materialize this year – to widespread joy. Of course, any climate scientist will tell you that an unusually warm month — or even a whole warm winter — doesn't mean much. It's the long-term trend that counts.

Many middle and high school science teachers are getting climate change wrong.

That's according to the results of a new, national teacher survey backed by the National Center for Science Education and published in the journal Science.

Before we get to those results, a quick, climate science refresher is in order.

NPR science correspondent Christopher Joyce says the world's major scientific organizations are now clear on global warming:
