Climate conditions in much of the Persion Gulf/Arabian Peninsula area will often push past the limits of human adaptability by the end of this century under current greenhouse gas pollution trends, according to a new report in Nature Climate Change. These
It's always been hot in the Persian Gulf region. But a new report finds that without action to limit climate change, the combination of rising temperatures and humidity will often push much of the region beyond the limits of human adaptability.
Ninety five percent of urban Tanzanians use charcoal for cooking fuel, and the trade supports more than a million jobs. But charcoal production is taking a massive toll on the country's forests. After a failed attempt to ban the trade the country is now t
The illegal charcoal trade is a big contributor to deforestation in countries like Tanzania. After trying and failing once to curb the business, the country is now trying a new approach. The World's Sam Eaton has the story.
Toxic foam is a reality of life during the rainy season in parts of Bangalore, in eastern India. The foam froths up when rains churn up lakes laced with millions of gallons of residential and industrial pollutants, including phosphate laundry detergents b
When the rains come to Bangalore, India, residents have to navigate a bizarre urban hazard — a lake that froths up and fills the city with a toxic and sometimes flammable foam.
 Marine biologist Alice Lawrence assesses coral bleaching at Airport Reef in American Samoa.
Coral reefs support a quarter of the life in the sea and the livelihoods of half a billion people. But they're facing a serious threat from rising ocean temperatures.
Can humans replicate this wonder of nature, to help in the battle against climate change? Leaves, and the photosynthesis that powers them, suck CO2 out of the air and turn it into a valuable raw material. Scientists are trying to do the same, and use the
Researchers believe that artificial photosynthesis that sucks excess CO2 out of the air could one day help fight climate change. But capturing the gas is only half the challenge. The other half is what to do with it once you've got it. Lauren Sommer reports on a potentially breakthrough technology that uses artificial photsynthesis to turn CO2 from the air into industrial chemicals and natural gas.
Trees and other green plants are nature's tools for sucking CO2 out of the air, but scientists say there aren't nearly enough trees to remove all the waste gas we've put into the atmosphere. So some are trying to create new devices that work like trees —
Trees are nature's tool for pulling carbon dioxide out of the air, but there aren't enough trees in the world to suck up all the CO2 humans are putting there. That's why researchers are pushing to create artificial leaves to help fight climate change. The World's Ari Daniel visits with two teams of researchers pursuing different approaches to the formidable challenge.
A woman carrying a baby, both wearing masks, make their way down a street and away from the site of explosions, in Tianjin, China.
The current crisis is only the beginning for residents displaced by devastating explosions at the Chinese port of Tianjin. Traces of cyanide and other toxic chemicals have been reported in the air, which have prompted further questions and concerns.

With storms intensifying and sea levels rising, the lessons of Katrina are lessons for all of us.
Fire engines at the site of the explosions the Chinese port city of Tianjin on August 13th. Two huge explosions tore through an industrial area where toxic chemicals and gas were stored, killing scores of people including fire fighters.
Chemical blasts kill scores of people and destroy a section of an important Chinese port. What safety precautions should be in place to prevent this from happening again — in China or elsewhere.
A woman wearing a mask rides her bicycle along a street on a hazy morning in Beijing, February 28, 2013. Beijing's environmental authorities said that day air quality in Beijing and nearby regions hit dangerous levels, Xinhua News Agency reported.
China is one place where leader don't have to grapple with politics to implement such rules.
