For years, national leaders have failed to create sustainable climate change solutions, and poorer nations and communities have borne the brunt of inaction. Now human rights issues are getting much more attention.
For years, the coal industry has enjoyed tax benefits and exemptions from strict environmental regulations. But those days might be over: President Barack Obama is using EPA authority under the Clean Air Act to try to curb coal power plant emissions, including CO2 and mercury. But coal interests are fighting back in the courts.
Seals spend a lot of time in the water — which makes them nearly ideal vehicles for gathering data on ocean currents and changes in ocean conditions. But doing that requires a little bit of cooperation from the seals.
Helsinki, the capital of Finland, is growing fast. The public transit system is already overcrowded, and there is little money for investing in new roads and highways. City planners say they need a better way for people to get around.
Copenhagen is the greenest city in the world, and its carefully planned green rooftops are helping it reach that spot. The rooftop oases help trap carbon and water, support biodiversity and help the city prepare for the warmer future that's coming thanks to climate change.
A deal signed by the US and China last month was not only the first major climate agreement that China has signed: It's also setting an example as the world prepares to hash out a new climate deal in 2015, giving much-needed momentum to talks currently taking place in Peru.
Texas is the biggest climate polluter in the U.S. It’s also is also extremely vulnerable to some of the impacts of climate change. But the state’s most prominent politicians say they don't believe that climate change is real. It all adds up to a big problem for Texas and the rest of us.
In his new book, Urban Acupuncture, Jaimer Lerner, the mayor who revolutionized the public transit system of Curitiba, Brazil, and cleaned up its waste, documents ways various cities create pleasant and sustainable atmospheres.
Scientists are warning West African villagers to stop hunting bush meat and to stay away from fruit bats as they circle in a possible animal source for the latest Ebola outbreak. The Ebola virus lives in fruit bats, scientists believe, and is threatening communities who are already facing the deadliest Ebola outbreak in history.
You may have noticed that more and more wine bottles — even expensive ones — are increasingly coming with screw tops and synthetic stoppers.

Italy is a fiercely anti-GMOs. It's one of a handful of countries to ban them outright. But European law is trumping them, and it has opened a window for one Italian farmer who is growing GMO corn anyway.
Sweden's successful waste-to-energy program converts household waste into energy for heating and electricity. But they've run into an unusual problem: they simply aren't generating enough trash to power the incinerators, so they've begun importing waste from European neighbors.
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.
While the US is using less coal than we have in the past, we plan to export more coal to Asia. That means transporting it by trains, as we’ve done for decades. But there’s very little research on the effects coal has on the environment when it escapes from coal hoppers bumping along the rails.
Rare earth elements are critical to modern technology, including in technology useful in national defense. Most rare elements come from China, but a new mine in Alaska could shift the balance. But there are risks, including to the environment, from the proposed mine.
The Arctic region may be cold, but its politics are heating up as the changing climate melts more of the polar ice and for longer periods of time. Iceland's president wants his country and the US to be players in plans for the Arctic
For the past eight years, an international ban has protected Brazil's forests from being cleared to grow soybeans. But that ban expires in December, and some people in Brazil fear that soy farmers are coming soon for their forests.
Peru is a dry country, dependent on glaciers for virtually all of its water supply. But as the climate changes, the glaciers are drying up and vanishing. But two Peruvian entrepreneurs have conceived homemade solutions to try and reverse the disappearance of Peru's lifeline.
New images and reports have surfaced of wholesale torture and starvation on the part of the Syrian regime, just as peace talks to end the war are set to start on Wednesday. On the US west coast, scientists dispel fears that Pacific Ocean fish are contaminated with Fukushima radiation. And side-by-side men's toilets at an Olympic venue have become a social media joke. That and more, in today's Global Scan.
For our Geo Quiz today we were looking for a Central American country that's a popular stopover for migrating hawks. Panama is the answer, and reporter Murray Carpenter takes us to a hawk watch in Panama City.
