A Wrenching Choice for Alaska Towns in the Path of Climate Change

http://www.nytimes.com/interactive/2016/11/29/science/alaska-global-warming.html Source:   Text by ERICA GOOD, Photographs and video by JOSH HANER, The New York Times For Investigation:   10.3 Excerpt: ...Laid out on a narrow spit of sand between the Tagoomenik River and the Bering Sea, [Shaktoolik] the village of 250 or so people is facing an imminent threat from increased flooding and erosion, signs of a changing climate. With its proximity to the Arctic, Alaska is warming about twice as fast as the rest of the United States and the state is heading for the warmest year on record. The government has identified at least 31 Alaskan towns and cities at imminent risk of destruction, with Shaktoolik ranking among the top four. Some villages, climate change experts predict, will be uninhabitable by 2050, their residents joining a flow of climate refugees around the globe, in Bolivia, China, Niger and other countries....

Great Barrier Reef suffered worst bleaching on record in 2016, report finds

  http://www.bbc.com/news/world-australia-38127320 Source:   By Hywel Griffith, BBC News, Sydney For Investigation:   10.3 For GSS Losing Biodiversity chapter 7. Excerpt: Higher water temperatures in 2016 caused the worst destruction of corals ever recorded on Australia's Great Barrier Reef, a study has found. Some 67% of corals died in the reef's worst-hit northern section, the ARC Centre of Excellence for Coral Reef Studies report said. The situation was better in the central section, where 6% perished, while the southern reef is in good health. ...This year's mass bleaching was the worst-ever recorded on the Great Barrier Reef, following two previous events in 1998 and 2002. Professor Hughes is certain that the increased water temperature is the result of carbon emissions, and warns that climate change could bring annual bleaching within 20 years. "Most of the losses in 2016 have occurred in the northern, most pristine part of the Great Barrier Reef," he s

Perils of Climate Change Could Swamp Coastal Real Estate

URL Source:   By Ian Urbina, The New York Times For Investigation:   10.3 Excerpt: MIAMI — Real estate agents looking to sell coastal properties usually focus on one thing: how close the home is to the water’s edge. But buyers are increasingly asking instead how far back it is from the waterline. How many feet above sea level? Is it fortified against storm surges? ...Rising sea levels are changing the way people think about waterfront real estate. Though demand remains strong and developers continue to build near the water in many coastal cities, homeowners across the nation are slowly growing wary of buying property in areas most vulnerable to the effects of climate change. A warming planet has already forced a number of industries — coal, oil, agriculture and utilities among them — to account for potential future costs of a changed climate. The real estate industry, particularly along the vulnerable coastlines, is slowly awakening to the need to factor in the risks of catastrop

Largest Ever U.S. Shale Oil Deposit Identified in Texas

https://eos.org/articles/largest-ever-u-s-shale-oil-deposit-identified-in-texas Source:   By Aaron Sidder, Earth & Space News (EoS), AGU For Investigation:   10.3 Excerpt: As global oil prices remain mired in their worst downturn in decades, news from western Texas suggests that petroleum fortunes continue to smile on the region. In its first assessment in nearly a decade of the Permian Basin, a large sedimentary basin underlying parts of Texas and New Mexico, the U.S. Geological Survey (USGS) has determined that a vast deposit of shale there, known as the Wolfcamp shale, contains much more oil than previously estimated. ...the region contains what is estimated to be the largest amount of continuous oil—meaning oil accessible only by means of hydraulic fracturing, or fracking—ever assessed in the United States. The agency estimated the Wolfcamp shale contains 20 billion barrels (3.2 billion cubic meters) of oil that can be recovered using today’s technology. That’s nearly 3 ti

They may save us yet: Scientists found a way to turn our carbon emissions into rock

https://www.washingtonpost.com/news/energy-environment/wp/2016/11/18/they-may-save-us-yet-scientists-found-a-way-to-turn-our-carbon-emissions-into-rock/ Source:   By Chris Mooney, The New York Times For Investigation:   10.3 Excerpt: Earlier this year, a project in Iceland reported an apparent breakthrough in the safe underground storage of the principal greenhouse gas, carbon dioxide — an option likely to be necessary if we’re to solve our global warming problem. The Carbfix project, run by a leading Icelandic producer of geothermal power, Reykjavik Energy, announced that it had successfully injected 250 tons of carbon dioxide, dissolved in water, into an underground repository of volcanic rocks called basalts — and that the carbon carbon dioxide ...had apparently become one with the basalt, undergoing a fast chemical reaction and forming a type of rock called a carbonate in two years’ time. ...And now, a group of American researchers has taken the science even farther....

The average U.S. family destroys a football field's worth of Arctic sea ice every 30 years

http://www.sciencemag.org/news/2016/11/average-us-family-destroys-football-fields-worth-arctic-sea-ice-every-30-years Source:   By By Warren Cornwall, Science For Investigation:   Excerpt: The jet fuel you burned on that flight from New York City to London? Say goodbye to 1 square meter of Arctic sea ice. Since at least the 1960s, the shrinkage of the ice cap over the Arctic Ocean has advanced in lockstep with the amount of greenhouse gases humans have sent into the atmosphere, according to a study published this week in Science. Every additional metric ton of carbon dioxide (CO2) puffed into the atmosphere appears to cost the Arctic another 3 square meters of summer sea ice—a simple and direct observational link that has been sitting in data beneath scientists' noses. "It's really basic," says co-author Dirk Notz, a sea ice expert at the Max Planck Institute for Meteorology in Hamburg, Germany. "In retrospect, it sounds like something someone should have d

Batteries That Make Use of Solar Power, Even in the Dark

http://www.nytimes.com/2016/11/03/business/energy-environment/batteries-that-make-use-of-solar-power-even-in-the-dark.html Source:   By Stanley Reed, The New York Times For Investigation:   10.3 Excerpt: HARTWELL, ENGLAND — A new cash crop has sprung up on Nicholas Beatty’s enchanting farm near here. Rows of gray solar panels range over about 25 acres, turning sunlight into electricity, as dog-size muntjac deer hop by. The panels themselves, trouble-free money earners that feed into the electric grid, are no longer unusual on farms in Britain or other countries. What’s new in Mr. Beatty’s field is a hulking 40-foot-long shipping container. Stacked inside, in what look like drawers, are about 200 lithium-ion cells that make up a battery large enough to store a substantial portion of the electricity the solar farm puts out. ...Power prices in Britain and elsewhere rise and fall, sometimes strikingly, during the day and over the year, depending on the supply and demand.
