In vitro fertilization may save coral reefs

http://www.sfgate.com/bayarea/article/In-vitro-fertilization-may-save-coral-reefs-8326086.php Source:   By David Perlman, San Francisco Chronicle For Investigation:   10.3 Excerpt: Marine biologists at the California Academy of Sciences have joined a new international effort to rescue endangered coral reefs from the consequences of widespread human destruction and a warming climate. Teams of research divers from the academy will set off this summer on expeditions to the Caribbean and Mexico, where they will seed two of the region’s major reefs with millions of coral larvae born from the organisms’ sperm and egg cells. ...corals are actually colonies of tiny animals that build their limestone homes from the sea, and derive their colors from the algae that live inside them. Their lives are increasingly threatened by global plagues like expanding human development, ocean pollution, and the twin signals of global climate change: rising temperatures and increasing ocean acidification.

As Wind Power Lifts Wyoming’s Fortunes, Coal Miners Are Left in the Dust

http://www.nytimes.com/2016/06/20/us/as-wind-power-lifts-wyomings-fortunes-coal-miners-are-left-in-the-dust.html Source:   By Coral Davenport, The New York Times For Investigation:   10.3 Excerpt: ...In Wyoming, the country’s biggest coal-producing state, the energy landscape is transforming along with the nation’s, but in a state of 584,000 people, that change is happening at hyperspeed. ...The new positions and financial opportunities offered by wind and other new-energy industries are not replacing all the jobs going up in coal smoke. ...The thousands of coal workers who will probably lose their jobs do not necessarily have the technical skills to operate wind farms. In any case, new wind jobs will number in the hundreds, not the thousands. ...Today, about 66 percent of the electricity in the United States is produced by coal and natural gas, and just 7 percent is produced by renewable sources such as wind and solar. But market forces and government regulations are rapidly chan

Australian Rodent Is First Mammal Made Extinct by Human-Driven Climate Change, Scientists Say

http://www.nytimes.com/2016/06/15/world/australia/climate-change-bramble-cay-rodent.html Source:   By Michelle Innis, The New York Times For Investigation:   Excerpt: SYDNEY, Australia — Australian researchers say rising sea levels have wiped out a rodent that lived on a tiny outcrop in the Great Barrier Reef, in what they say is the first documented extinction of a mammal species due to human-caused climate change. ...The long-tailed, whiskered creature, called the Bramble Cay melomys, was considered the only mammal endemic to the Great Barrier Reef. “The key factor responsible for the death of the Bramble Cay melomys is almost certainly high tides and surging seawater, which has traveled inland across the island,” Luke Leung, a scientist from the University of Queensland who was an author of a report on the species’ apparent disappearance, said by telephone. “The seawater has destroyed the animal’s habitat and food source. This is the first documented extinction of a mammal bec

Underground injections turn carbon dioxide to stone

http://www.sciencemag.org/news/2016/06/underground-injections-turn-carbon-dioxide-stone Source:   By Eli Kintisch, Science For Investigation:   10.3 Excerpt: Researchers working in Iceland say they have discovered a new way to trap the greenhouse gas carbon dioxide (CO2) deep underground: by changing it into rock. Results published this week in Science show that injecting CO2 into volcanic rocks triggers a reaction that rapidly forms new carbonate minerals—potentially locking up the gas forever. The technique has to clear some high hurdles to become commercially viable. ...unlike sandstone, the basalt contains metals that react with CO2, forming carbonate minerals such as calcite—a process known as carbonation. But they thought the process might take many years. To find out, they launched the CarbFix experiment 25 kilometers east of Reykjavik, intending to dose Iceland’s abundant underground basalt with CO2 that bubbles from cooling magma underground and is collected at a nearby g

Climate change could trigger tropical evacuations, researchers advise

http://news.berkeley.edu/2016/06/09/climate-change-could-trigger-tropical-evacuations-researchers-advise/ Source:   By  Kathleen Maclay, UC Berkeley News For Investigation:   10.3 Excerpt: Global warming by just 2 degrees Celsius is likely to force some tropical plant, animal and human populations to relocate hundreds of miles from their current homes this century, according to research published today in the journal Scientific Reports [http://dx.doi.org/10.1038/srep25697]. Solomon Hsiang, Chancellor’s Associate Professor of Public Policy at the University of California, Berkeley, and Adam Sobel, a professor of applied physics and math at Columbia University, foresee dramatic population declines in Mexico, Central America, Africa, India and other tropical locales if ecosystems or humans move due to climate change. In their analysis, the pair used a model to demonstrate how climate dynamics in the tropics can dramatically magnify the consequences of climate change as it is experien
