California Still in Widespread
Drought, Despite Heavy Precipitation
The heavy rains and snow that fell across much of California in the first half of December did little to recharge the state's
California precipitation deficits
dry reservoirs or ease long-term drought conditions, an analysis
by the National Oceanic and Atmospheric Administration (NOAA) confirms. By the middle of December, 98 percent of the state remained under drought conditions, which is the same portion as before the storms, according to the U.S. Drought Monitor. Dry conditions over the last three years have left the Sierra Nevada mountain range with a 30- to 50-inch precipitation deficit, NOAA reports, and the agriculture-heavy San Joaquin Valley has fared even worse. To bring the state's four-year precipitation total out of the bottom 20 percent historically — a benchmark used to declare drought conditions — every part of the state would need to exceed its average rainfall between now and September.

'Nuisance Flooding' Will Affect
Most of U.S. Coastline by 2050, Report Finds
By 2050, most U.S. coastal areas are likely to be threatened by 30 or more days of flooding each year due sea level
Nuisance flooding projections for U.S. cities
rise, according to
a new report the National Oceanic and Atmospheric Administration (NOAA). The researchers looked at the frequency of so-called "nuisance flooding," which occurs when the water level reaches one to two feet above local high tide, and found that several cities along the East Coast are already seeing more than 30 days of nuisance flooding each year. Additional major cities — including Baltimore, Atlantic City, Philadelphia, and San Francisco — will reach or exceed that benchmark by 2030, the report says. Although nuisance flooding is not typically catastrophic or dangerous, it is often costly. The report drives home the point, researchers say, that such floods will become commonplace far earlier than 2100, which is generally cited as the date when sea level rise is likely to become damaging.

Clearing Rainforests Distorts
Global Rainfall and Agriculture, Study Says
Clearing forests not only releases carbon into the atmosphere, it also triggers worldwide shifts in rainfall and temperatures
Global effects of forest loss
that are just as potent as those caused by current carbon pollution and that pose great risk to future agricultural productivity, researchers report
. Deforestation in South America, Southeast Asia, and Africa may alter growing conditions in agricultural areas as far away as the U.S. Midwest, Europe, and China, the study in Nature Climate Change
finds. The researchers calculate that complete tropical deforestation could trigger atmospheric changes leading to an increase of 0.7 degrees Celsius in global temperatures, in addition to warming caused by greenhouse gases released from the deforestation itself. That would double the observed global warming since 1850, the researchers note. They say their findings indicate that many of the predicted changes associated with widespread deforestation are already occurring — from Thailand, which is receiving less rainfall at the beginning of the dry season, to parts of the Amazon, where once-predictable rainfall has shifted notably.

of the most productive fishing grounds in the nation, from future oil and gas development. The president's action is expected to benefit commercial fishermen and Native Alaskans and boost conservation efforts in the region, which is roughly the size of Florida. Noting that Bristol Bay is the world's largest sockeye salmon fishery and the source of 40 percent of U.S. wild-caught seafood — a catch worth $2 billion annually — Obama vowed to ensure long-term safeguards for the bay. The region has been under protection intermittently since 1989, when the Exxon Valdez spill prompted a federal moratorium on offshore drilling. "It is a natural wonder, and it’s something that’s just too precious to be putting out to the highest bidder," Obama said in a video message
. The federal government is still considering whether to allow development of what would be North America's largest open-pit mine
in the bay's watershed.

China’s Lake Ebinur Has Been
Shrinking Dramatically, NASA Image Shows
As this NASA satellite image shows
, Lake Ebinur, located in northwestern China near the border of
Kazakhstan, has shrunk by 50 percent since 1955 as a result of development, agriculture, and natural fluctuations in precipitation. The lake’s saline water is light blue, and the dried lake bed appears white due to salts and other minerals that have been left behind as the water evaporates. The lake’s size fluctuates from year to year due to natural variations in snowmelt and rainfall, and human activity also plays a key role, Chinese researchers say. The nearby city of Bole, with a population of 425,000, consumes significant amounts of water, and farmers irrigate their crops — especially cotton — with water that would otherwise flow into the lake, researchers say. Frequent saline dust storms contribute to desertification, damage soils, harm wetlands, and may be hastening the melting of snow and glaciers downwind, researchers say.

Scientists Find Seafloor Fallout Plume of Oil from Deepwater Horizon Spill
Researchers say they have found a large fallout plume of oil on the seafloor from the 2010 Deepwater Horizon
Deepwater Horizon oil at the surface of the ocean
disaster in the Gulf of Mexico. According to a report in the Proceedings of the National Academy of Sciences
, a portion of the 2 million barrels of oil thought to be trapped in the deep sea after the spill appears to have settled across a 1,250-square-mile patch of the seafloor centered around the Macondo Well, which discharged an estimated 5 million barrels of oil in the nearly three months between its blowout in April and eventual capping in July. The oil is concentrated in the top half-inch of the seafloor, and mostly distributed in patchy deposits to the southwest of the well, the study found. These deposits account for between 4 and 31 percent of the Macondo oil sequestered in the deep ocean, researchers estimate. The rest has likely been deposited outside this area, they say, but has evaded detection so far because of its patchiness.

Forests Protect Waterways
From Nitrogen Pollution, Researchers Find
Forest top soils capture and stabilize nitrogen pollution very quickly but release it slowly, according to new research published in the journal Ecology
. The findings indicate that mature forests may be providing an under-appreciated service by storing excess nitrogen, which can lead to algal blooms and oxygen-depleted dead zones if too much is released into lakes and waterways. Older forests store nitrogen more efficiently than young forests recovering from clear-cuts, the researchers found
, because they have accumulated more top soil and organic matter within the forest floor. Previously, it had been unclear how mature forests continued to capture and store nutrients such as nitrogen after they stopped adding tree biomass. The new research indicates it’s likely due to the delay between nitrogen uptake, which happens within days, and nitrogen release, which unfolds over years and decades.

Desert and Mediterranean Plants
More Resistant to Drought than Expected
Desert and Mediterranean ecosystems may be more resistant to climate change, particularly long-term
Plants in a Mediterranean ecosystem in Chile.
drought, than previously thought, a new study published in Nature Communications
shows. Over the course of a nine-year experiment, researchers subjected plants in four different climatic zones to rainfall conditions predicted under future climate change scenarios. The ecosystems typically received 3.5 to 30.7 inches of precipitation annually, and researchers cut that total by roughly 30-percent to simulate drought conditions. Surprisingly, the researchers found no measurable changes in plant biomass, density, or species composition and richness in any of the four ecosystems over the course of nine generations of plants. The ecosystems already receive highly variable amounts of rainfall and the 30-percent drop likely falls within the plants’ natural "comfort zone," the researchers say, which could explain the unexpected resilience to drought.

Aral Sea Basin Dry for First
Time in Modern History, Images Show
For the first time in modern history, the eastern basin of the South Aral Sea has gone completely dry, as this
NASA satellite image
captured in late August shows. The Aral Sea is an inland body of water lying between Kazakhstan and Uzbekistan in central Asia. It was once one of the four largest lakes in the world, but it has been shrinking markedly and dividing into smaller lobes since the 1960s, after the government of the former Soviet Union diverted the region's two major rivers to irrigate farmland. One Aral Sea researcher suggested that it has likely been at least 600 years since the eastern basin entirely disappeared. Decreasing precipitation and snowpack in its watershed led to the drying this year, and huge withdrawals for irrigation exacerbated the problem. Water levels are expected to continue to show major year-to-year variations depending on precipitation and snowpack levels, the researcher said.

Food Security Issues Often
Neglected After Extreme Weather Events
Extreme weather events — the sort likely to arise with increasing frequency as the planet warms — took a heavy toll on Russia and East Africa in 2010 and 2011, in large part because governments and authorities were ill-equipped to address resulting food shortages and other fallout, according to researchers at the University of Oxford. Russia experienced a heat wave that led to food hoarding and price-fixing of staple crops by speculators, according to the report, which was commissioned by Oxfam
. A drought in East Africa in 2010 through 2011 was tied to an uptick in armed conflicts in the region, which interrupted international and domestic aid for six months. Crop prices reached record levels in several markets, including wheat in Ethiopia, maize in Kenya, and red sorghum grain in Somalia, the report notes. Investing in additional health facilities, establishing pre-positioned food supplies, and other tactics aimed at mitigating the effects of future heat waves, droughts, and floods, could help to blunt the effects of climate change on the poorest and most vulnerable populations, the researchers say.

Mobile Phone Networks Can
Help Monitor Global Rainfall, Study Says
New research shows
that mobile phone networks, which cover 90 percent of the world's population, can help track rainfall events — a task that has proven difficult for both advanced satellite systems
and ground-level observation networks. By compiling data on signal disruptions from mobile phone networks in Burkina Faso in West Africa, a team of researchers was able to calculate with 95 percent accuracy both the location and volume of rain that fell, even during short-lived storms, according to a report in Geophysical Research Letters
. Mobile phone companies maintain detailed records on signal disruptions, which can occur when water droplets block and deflect signals between antennae, to determine whether their networks are functioning properly. By tapping into those records, researchers could distill data on rainfall events at extremely fine spatial and temporal scales. As mobile phone networks expand across the globe, such data could be used to create highly accurate rainfall maps, researchers say, although gaining access to records could prove difficult.

Six Strategies Could End
Global Water Stress by 2050, Scientists Say
Global water stress could be alleviated by the year 2050 if countries work to implement six key strategies
ranging from building more reservoirs to controlling population growth, according to
research from Canada and the Netherlands. Water stress is defined as occurring when more than 40 percent of the water from a region's rivers is unavailable because it is already being used — a situation that currently affects roughly one-third of the global population. Writing in Nature Geoscience
, the scientists propose six steps they believe can help reduce water stress: planting crops that use water and nutrients more efficiently; using more efficient irrigation methods; improving the efficiency of water use in homes, industry, and municipalities; limiting the rate of population growth so global population stays below 8.5 billion by 2050; increasing reservoir water storage capacity; and intensifying water desalination operations

New Database Tracks Ecological
Health Impacts of Dams on World's Rivers
A newly launched online database
illustrates the impacts of nearly 6,000 dams on the world's 50 major
river basins, ranking their ecological health according to indicators of river fragmentation, water quality, and biodiversity. The "State of the World's Rivers" project was developed by the advocacy organization International Rivers
and created using Google Earth. Users can compare the health of individual river basins, see the locations of existing and planned dams, and explore 10 of the most significant river basins in more depth. The 6,000 dams represented in the database are a small percentage of the more than 50,000 large dams that impact the world's rivers, the organization notes.

Meat Production, Especially
Beef, Strains Land and Water, Study Says
Global meat production has expanded more than four-fold over the last 50 years — and 25-fold since
Beef cattle graze in Colombia
1800 — due to growing purchasing power, urbanization, and changing diets, according to a new report from the Worldwatch Institute
. Consumers in industrial countries still eat much larger quantities of meat (75.9 kilograms per person) than those in developing nations (33.7 kilograms), though that gap is beginning to close, the report says. Nearly 70 percent of the planet's agricultural land and freshwater is used for livestock, with additional land and water used to grow grains for livestock feed. Beef production alone uses about three-fifths of global farmland and yields less than 5 percent of the world's protein, according to the report. Sustainable agricultural practices
such as feeding livestock with grasses instead of grains and using natural fertilizers could reduce these impacts, the report notes, but alternative dietary choices hold the most immediate promise for reducing the environmental footprint of meat production.

Drought in Western U.S.
Has Caused Land to Rise, Researchers Say
The western U.S. has lost so much water during the ongoing severe drought that the land has sprung up by
GPS station in California's Inyo Mountains
as much as 15 millimeters (0.6 inches), according to a study in the journal Science
. Water at the surface of the earth typically weighs down the land, but the region has lost enough water that the tectonic plate underlying the western U.S. has undergone rapid uplift, much like an uncoiling spring, researchers explain. California's water deficit over the past 18 months has caused some of its mountain ranges to rise by more than half an inch, and the West overall has risen by 0.15 inches, according to the study. Using ground positioning data from GPS stations throughout the region, researchers from the University of California, San Diego, estimate the water loss to be 240 gigatons (63 trillion gallons) — equivalent to a nearly four-inch layer of water spread out over the entire western U.S.

Some Chemicals in Fracking
Fluids Raise Red Flags, Researchers Say
Of the more than 200 compounds used in hydraulic fracturing fluids, eight are toxic to mammals and the
A Marcellus Shale fracking operation
health risks of roughly one-third are unknown, according to
researchers at Lawrence Berkeley National Lab. Hydraulic fracturing, also known as fracking, is a drilling technique that releases natural gas and oil by injecting fluids with chemical additives deep into rock formations. The research team tracked down substances commonly used as fracking additives and found they include gelling agents to thicken the fluids, biocides to inhibit microbial growth, and compounds to prevent pipe corrosion. The industry claims the additives are non-toxic and food-grade, and while that is true in some cases, the researchers note, most fracking compounds require treatment before they can be safely released into the environment. Moreover, a number of chemicals that could pose health risks, such as corrosion inhibitors and biocides, are used in reasonably high concentrations in fracking fluids, the researchers note.

Western U.S. In Its Quietest
Fire Season In A Decade, Officials Report
The western U.S. is in the midst of its quietest wildfire season
in a decade, according to data from the National
Interagency Fire Center (NIFC). With 1.7 million acres burned through August 4, the 2014 fire season has destroyed well below the average of 4.4 million acres for the previous nine years through the same date. Fire season still has a few months left, however, and the year's good fortune may not last: Above normal fire potential is expected to continue
over most of California, Nevada, Oregon, Washington, and Idaho, according to the NIFC. Average temperatures have been 2 to 4 degrees above normal for most of the West; portions of the western Great Basin, northern California, and Pacific Northwest were 6 to 8 degrees warmer than normal; and exceptional drought conditions continue in California, western Nevada, and the Texas Panhandle, the center says.

California Takes Steps to
Curb Lawn Watering During Severe Drought
In the midst of a severe, long-term drought, California is taking unprecedented steps to discourage watering of

residential lawns, with some areas offering residents substantial cash incentives for installing water-saving landscaping, AFP reports
. The "Cash in Your Lawn" program in Los Angeles offers residents up to $6,000 ($3 per square foot) for replacing their lawns with drought-tolerant plants, rocks, and pebbles. Throughout the state, Governor Jerry Brown recently prohibited lawn watering more than two times per week and banned fines for brown lawns, which homeowner associations sometimes impose with the intent of improving a neighborhood's appearance. The drought, currently in its third year, threatens the water supply of California's 38 million residents. Agricultural regions
have already seen severe water reductions, placing extra pressure on the state's groundwater reserves.

Southwestern U.S. Aquifers
Are Extremely Low, NASA Data Show
Groundwater reserves in the U.S. Southwest are severely low and prospects for their long-term viability are bleak as persistent drought continues to parch the
land and prevent recharging, according to an assessment from NASA
. As shown in this map, many underground aquifers in the Southwest are extremely dry compared to average conditions over the past 60 years. Deep red areas on the map, such as in southern California and Nevada, depict aquifers that are so dry there's less than a 2 percent chance they could have experienced such levels of drought-related depletion since 1948. Although the Pacific Northwest is experiencing drought-related wildfires, its aquifers appear to be well-stocked, according to the map. The discrepancy is likely due to the long lag between dry conditions at the surface and depletion of groundwater reserves, researchers say.

California Agriculture Relying
Too Heavily on Groundwater in Drought
California's agriculture industry is relying too heavily on groundwater to irrigate drought-stricken farmlands — a trend that will not be sustainable long-term, according
Central Valley orchard
to a study
by the University of California, Davis. The drought, which is the third most severe on record, is responsible for the greatest water loss ever seen in California agriculture, with river water for Central Valley farms reduced by roughly one-third, the study found. Groundwater pumping will likely replace most river water losses, and some areas have more than doubled their pumping rate over the previous year. If the drought continues for two more years, the report says, groundwater reserves will continue to be depleted to replace surface water losses and pumping ability will slowly decrease, which could affect crop production. So far in the current drought, 428,000 acres of cropland — roughly 5 percent — has been made fallow across the Central Valley, Central Coast, and Southern California.

Human Activity Has Caused
Long-term Australian Drought, Model Shows
A new high-resolution climate model shows that southwestern Australia's long-term decline in fall and winter rainfall, which began around 1970 and has increased over the last four decades, is caused by
increases in man-made greenhouse gas emissions and ozone depletion, according to
research published in Nature Geoscience
. Simulating both natural and man-made climate effects, scientists showed that the decline in rainfall is primarily driven by human activity. Rises in greenhouse gas emissions and thinning of the ozone hole have led to changes in large-scale atmospheric circulation, including a poleward movement of the westerly winds and increasing atmospheric surface pressure over parts of southern Australia. This has led to decreased rainfall, the study said. The drying is most severe over southwest Australia, where the model forecasts a 40 percent decline in average rainfall by the late 21st century, with significant implications for regional water resources.

U.S. Breweries Cut Water
Use Amid Widespread Drought Conditions
Major breweries in the U.S. are cutting back on the amount of water they use to brew beer as drought threatens their water supplies, the Associated Press
reports. MillerCoors, headquartered in Chicago, has reduced its water use by 9.2 percent since 2012, a company sustainability report said. Earlier this month St. Louis-based Anheuser-Busch, the largest U.S. brewer, reported that it has cut water use by 32 percent in the last five years. Employing strategies such as fueling boilers with wastewater, recycling water used to clean bottles and cans, and installing sensors to fine-tune irrigation in hop and barley fields, MillerCoors has cut water use to 3.48 barrels of water for each barrel of beer, the company says. The company is also giving $700,000 to landowners in the watershed of its Fort Worth brewery who make efforts to curb erosion and runoff by, for example, planting native grasses or rotating cattle grazing lands. Craft breweries typically use twice as much water as major breweries per barrel of beer, the AP notes, because they are smaller in scale and don't have access to the same technology.

Group Will Pay Farmers
To Create Temporary Migratory Bird Habitat
started by The Nature Conservancy aims to enlist California farmers in creating temporary habitats for migrating birds — a partnership that could become
more important as the state's long-term drought continues and the birds' wetland habitats dwindle. Using crowdsourced data, The Nature Conservancy (TNC) tracks the paths of migratory birds on their annual journey from Canada to South America to determine where and when the birds will need suitable wetland habitat for stop-overs in California's Central Valley. Then, in a sort of reverse auction, TNC asks farmers how much they would charge to temporarily flood their land to accommodate the birds, and pays farmers with the lowest bids to do so for a few weeks or months. The Nature Conservancy says the year-old program has been a success, enabling the organization to rent habitat for roughly 0.5 to 1.5 percent of what permanent protection costs. The program's budget is $1 million to $3 million annually. Forty farmers flooded roughly 10,000 acres last year, and sightings of key migratory bird species were 30 times above average, according to TNC.

Trash-scooping Water Wheel
Cleans up Garbage From Baltimore Harbor
A new contraption
in a Baltimore river is helping to clear trash and debris — up to 50,000 pounds of it each day — from the city's Inner Harbor. The 50-foot-long
"water wheel" gathers garbage floating in the Jones Falls River, which runs through the city to the Baltimore Inner Harbor, and deposits it in a large dumpster so the trash can be hauled away. Two large booms funnel debris toward a conveyor belt powered by the wheel, which itself is powered primarily by the flowing river. When the flow isn't strong enough to turn the wheel, water pumps, run by solar panels lining a canopy over the wheel, turn on and push water up to spin the wheel. The water wheel was designed to handle the heavy debris and larger pieces of trash that the river often carries, said its designer, Baltimore-based Clearwater Mills. It began operating earlier this month and cost $750,000, with $500,000 of that contributed by the Maryland Port Administration, Co.Exist reports.

Half of U.S. is Experiencing
Some Degree of Drought, Analysis Finds
Half of the United States is in the midst of a drought, a recent analysis
from the U.S. National Drought Monitor found, with nearly 15 percent of the nation in extreme to
exceptional drought. Dry conditions are pushing north rapidly, along with warmer temperatures, and soil moisture and groundwater levels are low far in advance of the agricultural peak demand season, according to the National Drought Mitigation Center. Much of the Southwest and Great Plains regions have been in a persistent drought for several years, and as this map prepared by federal agencies shows, an exceptional drought is currently plaguing parts of those regions. The entire state of California is experiencing some level of drought, much of it extreme to exceptional. Snowpack is at half its typical level in many parts of the West and much of the snow has completely melted before it normally would, researchers say. The map is based on measurements of climate, soil, and water conditions from more than 350 federal, state, and local observers around the country.

. In one case, an earthquake
Fracking injection well in Louisiana
swarm in Oklahoma has been linked to a cluster of fracking injection wells up to 50 kilometers (31 miles) away, Cornell University researchers report. So-called "induced seismicity" — when human activity causes tremors in the earth's crust — is gaining attention as reports of earthquakes within the central and eastern U.S. have increased dramatically over the past few years. The rise coincides with increased hydraulic fracturing for oil and natural gas, and the injection of wastewater in deep disposal wells in many locations, including Colorado, Oklahoma, and Texas. According to the U.S. Geological Survey (USGS), an average rate of 100 earthquakes per year above a magnitude 3.0 occurred in the three years from 2010-2012, compared with an average rate of 21 events per year observed from 1967-2000.

Run-of-River Hydropower Set
For Big Gains, Turbine Maker Predicts
A type of hydroelectric technology known as "run-of-river" hydropower is set to grow 10-fold over the next decade
, potentially becoming a $1.4 billion industry,
Hugh Keenleyside Dam
according to Dutch turbine maker Tocardo International BV. Run-of-river hydropower stations redirect part of a waterway through a diversion to spin turbines and generate electricity. Run-of-river is considered a more benign type of hydropower than large dam projects because it is a smaller-scale technology that doesn't create large upstream reservoirs that flood ecosystems and disrupt a river's natural flow. Some conservation groups are concerned
that problems with migratory fish passage and other environmental issues could outweigh the power-generating potential of run-of-river hydro projects. The company implemented its first project to harness tidal streams at Den Oever, Holland, and it has been operating for five years.

Scale and Extent of Dam Boom
In China Is Detailed in Mapping Project
China is planning to build at least 84 major dams in its southwest region, as shown in a map from the Wilson Center, eventually boosting its hydropower capacity by more than 160 gigawatts. By next year China's capacity
will surpass Europe's, and by 2020 it's projected to be larger than that of the U.S. and Europe combined. An interactive map
shows the scale and number of major dams proposed, under construction, existing, and canceled. The dam rush is part of an ongoing effort by China to increase non-fossil energy sources to 11.4 percent of the country's total energy consumption — a goal that has gained urgency due to severe air pollution in many northern Chinese cities. However, the hydropower push is not without its own major environmental consequences
, the Wilson Center notes. The cascades of planned dams will submerge important corridors connecting tropical rainforests to the Tibetan Plateau that allow wildlife to migrate as temperatures rise.
A Personal Note on Peter Matthiessen,
Who Wrote Eloquently of the Natural World
For an editor, the prospect of working with Peter Matthiessen was intimidating. He was one of our finest writers, and he wrote with such poetic precision and lyrical grace that at first it felt presumptuous to propose
any changes to his writing at all. That feeling was heightened by his strong physical presence — an odd mix of Manhattan patrician, rugged outdoorsman, and Zen priest (all of which he was). And yet when I worked as his editor on several magazine articles in the 1990s, it was an immensely satisfying experience. He listened Zen-like, carefully considering all my editing suggestions (with him, they were suggestions
only), and to my delight, accepted almost all of them. Matthiessen died on April 5 at the age of 86, near the Long Island waters he so loved to fish. Read more of e360 editor Roger Cohn’s appreciation of Matthiessen.
