Mention greenhouse gas emissions and most people think carbon dioxide. But methane emissions are the second largest contributor to climate change. New data from satellite observations link strong methane emissions to coal bed methane extraction in the area of the US known as the Four Corners.
Reducing carbon intensity sounds like a good idea — until you do the math. In China, the math doesn't add up. Despite a pledge to reduce its carbon intensity, emissions in China continue to rise, and they will keep rising unless the government rejects it business-as-usual practices.
It's the season when kids are planning costumes and parents are stocking up on bags of candy. But in a northern Canadian town, there won't be trick-or-treating in the streets this Halloween because of the danger of roaming polar bears.
Heavy snowfall hit Nepal this week, trapping hikers on the popular Annapurna trail. Avalanches killed more than 25 trekkers and climbers, and hundreds more had to be rescued by helicopter. Scientists warn these storms may become more commonplace.
If you support urgent action on climate change, you might be forgiven for feeling cynical about the recent UN Climate Summit in New York. For years, governments have pledged to take strong measures, but 2013 was a record year for greenhouse gas emissions across the globe. But at least one climate activist is feeling hopeful.
New York is often seen as a proving ground for traits like perseverance and determination — "If I can make it there, I'll make it anywhere," as the song goes. It turns out the same thing is true for the city's trees.
As humanity's population has roughly doubled since 1970s, the earth has lost roughly half of its non-human animals over the past four decades. That's the sobering conclusion of a new report from the World Wildlife Fund, which pins the blame for that decline squarely on humans.
The differences between developed countries like the US and rising powers — and polluters — like China and India are well-known. But there's also a major gulf between Americans and Europeans on climate policy that is hurting efforts to reach a large-scale climate agreement.
You may have noticed that more and more wine bottles — even expensive ones — are increasingly coming with screw tops and synthetic stoppers. You might not think much about the stopper when you make a purchase, but cork producers want you to start. They're mounting a campaign to show that real cork is better for the planet.
Scientists say a massive ice sheet in Antarctica is starting to collapse. It's not going to slide into the ocean over night, but rather over centuries. Still, it will fall, scientists say. It's gotten to the point it can't be stopped — and that means rising sea levels.
A year ago, confronting the threats presented by climate change was front and center in President Obama's State of the Union address. But The World's environment editor Peter Thomson expects it to be a lot less prominent this year. That's politics. And that's the nature of climate change.
Half of North America's 650 bird species may be forced to change their current habitats because of climate change or perish — including the bald eagle and the common loon. A new Audubon Society study produced maps to show people which of their local birds are at risk.
The discovery of two giant holes in the ground in far northern Russia is raising all kinds of speculation about their origin. No one yet knows for sure how they were formed, but a leading scientist is pointing to an ever-more usual suspect—climate change.
Hurricane Katrina was bad, but the future could be considerably worse, a new report says. "One of the greatest environmental and economic disasters in the nation's history is rushing toward a catastrophic conclusion, so far unabated and largely unnoticed."
Millions of tons of methane are stored in the earth's crust, frozen beneath a layer of Arctic permafrost. But as that permafrost melts, that methane is being released into the atmosphere, adding to climate change.
The Midwest United States is buried under a mountain of cold air, dropping temperatures to levels not seen in decades. A weather reporter says it has to do with the jet stream, which may be weakening due to ... global warming?
Palau and other Pacific island nations aren't represented at the United Nations by their own citizens. They're represented by American lawyers and law students. The Americans are pushing the UN to act quickly on climate change.
The BBC's Keith Adams reports on a solar-powered oven that's made out of cardboard and tinfoil. It could help combat climate change by offering an alternative for people who rely on firewood to cook their food. On PRI's The World.
The answer to today's Geo Quiz is the Maldives Islands, Anchor Marco Werman speaks with Charles Ehrhart, co-author of a study that attempts to chart how climate change will directly affect human populations.
The Sahel region of West Africa is being hit hard by climate change. But from the country of Burkina Faso, Mark Hertsgaard spotlights a small green miracle that's helping farmers fight the warming trend. The secret, he says, is trees. On PRI's The World.
