It's not news that Hong Kong, which brags one of the world's most stunning skylines, has been gradually losing it behind a curtain of smog.
But the Chinese territory's latest solution is new: To placate camera-clicking tourists unable to get those iconic shots of the skyscraper-studded waterfront, Hong Kong has set up a panoramic backdrop with clear, blue skies.
The Chinese website Netease published a series of pictures of tourists posing in front of the backdrop.
A study in the journal Nature could help explain why the Earth's average temperature hasn't increased during the past 15 years — despite a long-term trend of global warming.
The Earth's average temperature has risen by more than 1 degree Fahrenheit since the beginning of the Industrial Revolution. But the temperature rise has not been moving in lock step with the rise of carbon dioxide in the atmosphere. Carbon dioxide — mainly from burning fossil fuels — traps heat in the air.

A week without water can easily kill the average person.
But a garden that goes unwatered for months may produce sweeter, more flavorful fruits than anything available in most mainstream supermarkets — even in the scorching heat of a California summer. Commercial growers call it "dry farming," and throughout the state, this unconventional technique seems to be catching on among small producers of tomatoes, apples, grapes, melons and potatoes.
Across the High Plains, many farmers depend on underground stores of water, and they worry about wells going dry. A new scientific study of western Kansas lays out a predicted timeline for those fears to become reality. But it also shows an alternative path for farming in Kansas: The moment of reckoning can be delayed, and the impact softened, if farmers start conserving water now.
Blue turquoise waves lap at white sand on the Spanish island of Formentera in the Mediterranean Sea. Sweaty tourists from all over Europe cram the beach. But on this particular afternoon, no one dares take a cool dip in the water.
The reason? It's what Spaniards call "medusas" — named after the monster from Greek mythology, with a woman's face and venomous snakes for hair. In English, they're called jellyfish.
Gabrielle Amand's son was a recent victim of one. He's wrapped in a towel, sitting under an umbrella on the shore.
This is WEEKEND EDITION from NPR News. I'm Scott Simon. East Coast seabirds have had a tough year. They've been battered by storms and disruptions in the food chain. Among them, the sturdy little Atlantic puffin. Now, here in the United States, their numbers dwindle to just a single nesting pair by 1901. Since then, thanks to the Audubon Society's Project Puffin, they've made a comeback. But as WBUR's Fred Bever reports, the puffins are now facing some new threats.
Draft report from the intergovernmental panel on climate change was leaked to the media this week. The scientists will report to the U.N. that it is nearly certain that human activity has caused most of the earth's climate change over the last 50 years. Now, this leak is certain to rekindle debates about how best to contend with events like increasing temperatures and rising sea levels, and it might make some people take a new look at what's called geoengineering.
Next month, a scientific committee sponsored by the United Nations will put out its latest assessment of climate change. The report is expected to underscore yet again that climate change is a serious problem and human beings are largely responsible.
Imagine a robotic lab that can sample ocean organisms on its own and perform DNA analysis of what it finds. William Ussler, of the Monterey Bay Aquarium Research Institute, describes how a prototypical robotic explorer is helping study the life around undersea thermal vents.
Reporting in the Proceedings of the National Academy of Sciences, researchers write of a possible link between copper in drinking water and Alzheimer's disease in mice. Lead author Rashid Deane discusses the potential mechanism.

Updated at 12:35 a.m. Saturday: Emergency For San Francisco
Calif. Gov. Jerry Brown declared a state of emergency for San Francisco because of the wildfire's threat to public utilities there.
The fire is 150 miles from the city, but Brown said the fire jeopardizes San Francisco's power lines and stations in the fire area. The city has already had to shut down two of its three hydroelectric power stations, the AP reports.
Further damage could have an impact on San Francisco's power supply.
The Fukushima-Daiichi nuclear power plant is back in the news more than two years after an earthquake and tsunami triggered a series of meltdowns. New leaks found this week prompted regulators to consider raising the alert level there in Japan. NPR's science correspondent Geoff Brumfiel joined us to explain. Geoff, good morning.
While the Obama administration presses forward with plans to deal with climate change, Congress remains steadfast against taking action. It's not easy to find a scientist who will agree with that point of view. But Republicans have found an ally in a climate scientist by the name of Judith Curry.

This week's innovation pick is a shower head that reminds you you're taking too long. The Uji shower head gradually turns from green to red as users linger in the shower.
"It encourages [people] to take shorter and more energy efficient showers," said one of the co-inventors, Brett Andler. "By letting people become aware of how long they're in the shower, we've actually been able to cut shower time by 12 percent."

What's thick-skinned and leathery, about the size of an egg, essential for guacamole and sold eight for a dollar?
No, not limes. Hass avocados. This year, anyway. These pear-sized fruits usually weigh half a pound or more. In the summer of 2013, though, hundreds of thousands of trees in Southern California are sagging with the tiniest Hass avocados in local memory — some just the size of a golf ball.
Dolphins are washing ashore in alarming numbers in the Mid-Atlantic states this summer. More than 160 deaths of dolphins have been reported since early July and that's the worst fate in 26 years. Response teams from New York to Virginia are trying to determine just what's killing all these dolphins. Charlie Potter is working with one of those teams at the Virginia Aquarium and Marine Science Center.
Across the Southwest, cities are banning water-thirsty front lawns. Cado Daily of the University of Arizona's Water Wise Program views that as an opportunity to plant a "rainscape" — a yard with drought-friendly native plants that she says can look as lush as a lawn, and lure wildlife back, too.
Congress has gone home for its annual August recess, so Tell Me More takes a look at headlines in places across the country. Guest host Celeste Headlee talks with Mike Leary from the San Antonio Express-News and Dana Coffield of The Denver Post.
Relentless drought will force the government to cut back on water releases between Glen Canyon and Lake Mead. It's the first time that's happened since dams were built on the Colorado River. Reduction starts next year, and the announcement gives the 40 million water users in the Southwest time to plan.
For auto companies, that Environmental Protection Agency-approved MPG sticker on a new car is a high stakes and expensive process. These days it can be damaging to a company's image if customers can't achieve that great fuel economy in their own commutes.
Smart windows change how much sunlight they let through on a hot day. Such windows could reduce the demand for energy by reducing the need for air conditioning. This quest has been going on for years but it's got years to go before the project becomes a reality.

A federal appeals court ruled Tuesday that the Obama administration is breaking the law by delaying its review of a plan to store nuclear waste in Nevada. The court ruled that the Nuclear Regulatory Commission must complete its licensing process — that is, approve or reject — the Energy Department's plan for the waste site in Nevada.
NPR's Geoff Brumfiel filed this report for our Newscast unit:
"The Nuclear Regulatory Commission's original job was to issue or deny a license to build a nuclear waste dump inside Yucca Mountain, Nevada.

Two British scientists are dumping cold water on campaigns to promote urban beekeeping. They say that trying to "help the bees" by setting out more hives is naive and misguided if the bees can't find enough flowers nearby to feed on. You'll just end up with sick and starving bees.
