Pacific Island, Bigger Than Manhattan, Vanishes

You can see it on this Google Map — a little spit of land, sitting between Australia (on the left) and French-governed New Caledonia (on the right).

It's called "Sandy Island." In the Times Atlas of the World it's called "Sable Island." On both maps it's a conspicuous land mass, roughly 15 miles long from north to south, three miles across. Altogether, that's about 45 square miles — about one and a half times the size of Manhattan.

Nelson Kanuk's house is built on a melting tundra. In a year or two, it could be gone.

So the 18-year-old Yup'ik Eskimo is suing the state of Alaska, arguing the state needs to take more action on climate change.

"The river that runs in front of my house is called the Kugkaktlik River, and it means 'the middle one' in the Yup'ik language," Kanuk says.

Past Century's Global Temperature Change Is Fastest On Record

Originally published on Fri March 8, 2013 8:40 pm

Scientists say they have put together a record of global temperatures dating back to the end of the last ice age, about 11,000 years ago. This historical artwork of the last ice age was made by Swiss geologist and naturalist Oswald Heer.

There's plenty of evidence that the climate has warmed up over the past century, and climate scientists know this has happened throughout the history of the planet. But they want to know more about how this warming is different.

Now a research team says it has some new answers. It has put together a record of global temperatures going back to the end of the last ice age — about 11,000 years ago — when mammoths and saber-tooth cats roamed the planet. The study confirms that what we're seeing now is unprecedented.

Study Finds Climate Change To Open Arctic Sea Routes By 2050

Climate change will make commercial shipping possible from North America to Russia or Asia over the North Pole by the middle of the century, a new study says.

Two researchers at the University of California ran seven different climate models simulating two classes of vessels to see if they could make a relatively ice-free passage through the Arctic Ocean. In each case, the sea routes are sufficiently clear after 2049, they say.

Increased Humidity From Climate Change Could Make It Harder To Tolerate Summers

Originally published on Mon February 25, 2013 5:23 pm

AUDIE CORNISH, HOST:

Now, a story about heat, the sweaty, miserable kind. Heat plus humidity. Working outdoors or playing sports on a hot, muggy day can be dangerous, even deadly. And as the climate continues to warm, being outside will become even more challenging. Those are the findings of a new study in the journal Nature Climate Change.

NPR's Richard Harris tells us more.
