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.
With hundreds of years of experience behind them, the Netherlands are still pioneering ways to protect its communities from flooding. And as climate change makes flooding more of a global concern, other countries are paying attention to Dutch innovations.
Leaders from all over the world have gathered in New York to attend the UN Climate Summit. The first thing they heard was an impassioned poem from a mother and activist from the Marshall Islands, a tiny nation in the Pacific that may no longer exists if climate change isn't halted.
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.
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."
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.
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?
Leaf rust is eating away at coffee trees in Central and South America. Hundreds of thousands of people are out of work because of it. Now, an unlikely coalition of American coffee chains, coffee shops and bankers are coming to the rescue.
The answer to today's Geo Quiz is Ellesmere Island. An international dog sled expedition led by explorer Will Steger is currently crossing the island in an effort to document the effects of climate change.
Like Franklin Delano Roosevelt, President elect Obama is facing tough economic times, and an industrial challenge. While Roosevelt mobilized industry to fight a war, Obama pledges to mobilize to battle climate change. The World's Jason Margolis has more.
Droughts and floods can cause food crises. But so can politics and economics. Reporter David Hecht examines the roots of the 2005 food crisis in the West African nation of Niger and why so many children starved to death despite an adequate harvest.
President Obama and his Chinese counterpart Hu Jintao have agreed to work together to tackle some of the world's most pressing problems. The World's Mary Kay Magistad is covering the summit in Beijing.
