California plans to get 33 percent of its electricity from wind and solar power by 2020. But that will only work if the state can economically store some of the energy for release on cloudy, windless days.

To forecast sudden global catastrophe — and, perhaps, head it off — we should be spying on the climate at least as closely as we spy on each other, an expert panel warns. Yet the primary global monitoring network has been cut by 30 percent.

The U.S. aims to reduce carbon dioxide emissions by 80 percent by 2050. Wind and solar power can help. But folks doing the math say other pricey, controversial technologies — such as burying carbon gas underground, and expanding nuclear power — are also likely to be part of a low-carbon future.

Renewable energy has become a $220 billion a year industry. But to significantly slow climate change, the power of wind, solar and other renewable sources must vastly expand. Some say the tech breakthroughs needed are on the horizon, though a top economist sees a tougher road ahead.

Scientists say Typhoon Haiyan is one of the strongest ever recorded, though limited measurements may prevent them from declaring it as the record holder. Still, the storm was devastating: "We had a triple whammy of surge, very high winds and strong rainfall," says one climate scientist.

If you commute to work, chances are you travel on roads or rails. A designer in Austin, Texas, wonders, "Why not up in the air?" In a nod to orangutans at the National Zoo who get around on wires 50 feet above the ground, designers see the potential for aerial mass transit.

Diplomats are again meeting to consider setting aside a protected zone in the pristine waters around Antarctica, though their previous negotiations ended in failure. A scaled-back plan on the table this week would still create the largest marine preserve in the world.

This is the 40th anniversary of the Arab Oil Embargo, which triggered a seven-year energy crisis. The results of the energy crisis are still with us — both in the political fault-lines in Washington and in the cars that are on our roads.

"This is the real deal. Voyager 1 has finally reached interstellar space; the first time a spacecraft has been in the space between the stars," says one project scientist. Launched in 1977, the probe has been surveying the solar system.

About 160 years ago, Europe's glaciers began melting, centuries before the temperatures started rising. Now NASA scientists offer a possible explanation for this apparent paradox: Soot from the Industrial Revolution could have heated up the ice. (This piece initially aired Sept. 3 on Morning Edition.)

Scientists looking back on last year's extreme weather events conclude that human-induced climate change didn't cause any of the events, but appears to have made some of them worse. The results are published in the Bulletin of the American Meteorological Society.

About 160 years ago, before Europe began warming up, glaciers in the Alps started rapidly retreating. Now NASA scientists offer a possible explanation for this apparent paradox: Soot from the Industrial Revolution could have heated up the ice.

Greenland is covered in an ice layer that's up to 2 miles thick. But below the ice, there's a vast terrain of bedrock. Now scientists have found a mega-canyon there, twice the size of the one in Arizona. The hidden canyon is drawing oohs and aahs from scientists around the world.

The Earth's average annual temperature has been rising for decades, but not in the last 15 years — colder winters and hotter summers notwithstanding. Now scientists offer evidence that this "pause" in average warming is because a cooler Pacific is temporarily taking up more heat than usual.

Climate skeptics point to 15 years of no warming trend as a reason to doubt global warming. But Kevin Trenberth at the National Center for Atmospheric Research can explain a good bit of that temperature plateau — and he argues the Earth has continued to warm appreciably, even though our thin blanket of atmosphere hasn't.

When Republicans on Capitol Hill want to hear reasons not to take strong action on climate change, sometimes they call on Judith Curry to testify. The climatologist has staked out an unusual position on the subject: She says the climate is changing and people are partly responsible, but we shouldn't bother regulating carbon dioxide.

Sea level has been rising steadily as a result of global warming. But in 2010 and 2011, levels dropped sharply by a quarter of an inch. A new analysis says that's because extraordinarily heavy rainfall got trapped in inland Australia.

Carbon dioxide levels in the atmosphere cycle up and down as plants take it up in the summer and let some of it out in the winter. Over the past 50 years, these "breaths" have gotten larger, as plants in the Arctic are taking up more carbon dioxide during the warmer summers.
Friday, August 02, 2013
Paleontologists have been spending a lot of time studying the Earth of 50 million years ago, which was much hotter than it is today. They're hoping a glimpse into the planet's geologic past will show them how the planet will respond to all the carbon dioxide we're now putting into the air.

Oil developers in the Canadian Tar Sands are trying to understand some odd oil eruptions around several drilling platforms where oil is coming up through the ground rather than through the wells they drilled. The latest of these events tarred about 50 acres of forest.
