24 Oct 2014: New Mapping Tool Shows U.S. Geothermal Plants and Heat Potential

A new mapping tool from the U.S. Department of Energy lets users see how geothermal power plants

Geothermal power plants and heat flow potential
across the country are taking advantage of the heat stored within the earth’s crust. Most of the nation’s 154 operational and planned geothermal plants are clustered in western states, where geothermal heat potential is especially high (red areas). Notably, the map identifies two areas that appear ripe for new geothermal development: one in the Great Plains and another at the border of Virginia and West Virginia. The bulk of the facilities are conventional geothermal plants, which generate power using fluid found naturally deep below earth's surface. Steam captured at the surface spins a turbine, which then powers an electric generator. A newer type of technology, called enhanced geothermal, forces cold water from the surface down into the hot crust. Both types are generally considered clean sources of energy.

17 Oct 2014: Pesticide Linked to Bee Deaths

Soybeans (left) and corn coated with pesticides
banned in the European Union does not increase soybean yields compared to using no pesticides at all, according to an extensive review by the the U.S. Environmental Protection Agency (EPA). Seed treatment provides at most $6 in benefits per acre (an increase in revenue of less than 2 percent), and most likely no financial benefit at all, the EPA analysis concluded. The insecticides, known as neonicotinoids, are only effective for the first few weeks after planting, studies have found, when soybean pests are not typically active. Neonicotinoid seed treatments could theoretically help fend off sporadic and unpredictable pests, the report notes, but that benefit would be small and unlikely to be noticed outside of the southern U.S.

14 Oct 2014: Researchers Explain Puzzling
Stability of Some Himalayan Glaciers

Unlike nearly all other high-altitude glaciers across the globe, glaciers in the Karakoram mountain chain, part

of the Himalayas, are not melting and are even expanding in some areas. This so-called “Karakoram anomaly” has puzzled scientists for years, but now a team of researchers has offered an explanation: While rain from warm summer monsoons tends to melt mountain glaciers in other parts of the Himalayas and the nearby Tibetan Plateau, the location and height of mountains in the Karakoram chain, which runs along the borders of China, India, and Pakistan, protect the area from this seasonal precipitation. Instead, the mountain chain receives most of its precipitation in the form of winter snowfall, according to findings published in Nature Geoscience. The study suggests that the Karakoram glaciers are likely to persist until 2100, but not long after, if global warming continues at its current pace.

methane emissions, according to an analysis by researchers at the University of Michigan and Caltech. The area is centered in New Mexico's San Juan Basin near the shared borders of Colorado, Utah, and Arizona — the site of the largest and most active coalbed natural gas production operation in the U.S. Natural gas from the basin is more than 95 percent methane, a significantly more potent heat-trapping gas than carbon dioxide. Satellite measurements collected over seven years showed natural gas production operations in the area released roughly 650,000 tons of methane to the atmosphere each year. The methane emissions are not associated with hydraulic fracturing operations in the region, which began after the measurements were collected.

09 Oct 2014: Investment in Energy Efficiency
Outpaces the Renewable Energy Sector

Global investments in energy-efficiency measures have reached $310 billion annually — nearly $100 billion more than investments in renewable energy last year, according to a new report from the International Energy Agency. Efficiency measures saved the equivalent of 2 billion tons of oil between 2001 and 2011 in the 18 countries evaluated in the report, which is more than the annual energy demand of the U.S. and Germany combined. The residential sector saw the largest improvement in efficiency, with energy demand falling 5 percent from 2001 levels, according to the report. Homes and businesses are commonly turning to efficiency measures such as low-energy lighting, smart thermostats, and improved insulation to lower energy costs. To limit global temperature increases to no more than 2 degrees Celsius, the largest share of emissions reductions — 40 percent — will need to come from improvements in energy efficiency, the agency said.

But David Victor, a professor of international relations at University of California San Diego, argued in a recent controversial commentary in Nature that the 2-degree goal is now unattainable and should be replaced by more meaningful goals. In an interview with Yale Environment 360, Victor explains why he believes the 2-degree threshold has failed to position policy makers to take serious action on climate change and outlines the "basket of indicators" that he and his co-author are suggesting be used instead.

about the formation of continents, researchers say. Among other findings, they identified a ridge in the Gulf of Mexico that had previously been associated with seafloor spreading, a major rift in the South Atlantic Ocean, and thousands of sea mountains — all of which had never before been documented. The maps are based on small ripples and dips in the surface of the ocean, which can be detected by satellites, the researchers explain in the journal Science. Using these ocean surface variations, the scientists were able to infer the shape and contours of the new seafloor features. Previously, the only way to create detailed maps was to collect depth soundings from ships sailing directly over the seafloor, so only about 20 percent of the ocean floor had been accurately mapped, researchers say.

29 Sep 2014: Inexpensive Solar Cell
Makes Hydrogen Fuel from Sunlight

Researchers have developed a device that can store solar energy by inexpensively converting it to hydrogen —

Electrodes split water to hydrogen and oxygen.
an important step toward making solar power available around the clock. The technology, which which was recently described in the journal Science, is a type of "water splitter," a device that can efficiently divide water into its constituent parts: hydrogen and oxygen. The concept is important for solar energy storage because hydrogen gas can be used directly as fuel and is relatively easy to store, the researchers say. The device can convert 12.3 percent of the energy in sunlight to hydrogen, according to the report; conventional solar cells, in comparison, convert roughly 16 percent of energy from sunlight to electricity, but a significant portion of that energy is lost when converting it to a form that is easily stored. The design of this water splitter is an improvement over previous iterations, the researchers say, but the device's longevity and reliability will need to improve before it becomes a practical, large-scale solar energy storage option.

Combined historical and future carbon dioxide emissions must remain below 3.2 trillion metric tons to have a 66-percent chance of keeping that temperature increase below 2 degrees C — the internationally accepted benchmark for restraining global warming. But two-thirds of this allotment has already been emitted, and at the current pace of emissions, the global population will burn through the rest within the next 30 years, the researchers conclude. CO2 emissions rose 2.3 percent in 2013 and are on track to increase by 2.5 percent in 2014, according to the report, which was released ahead of this week's UN climate summit.

Among other findings, the analysis revealed increased emissions in China, India, Europe, and the northern U.S. in 2010, after the peak of the global financial crisis. The researchers say this reflects faster recoveries from the crisis in those regions compared to, for example, the southeastern U.S., where emissions lagged in 2010. The results of the analysis match ground-level measurements, confirming the accuracy of the maps, the researchers say.

04 Sep 2014: Buying Video Games on Disc Is
More Energy Efficient than Downloading

Downloading video games from the Internet creates a larger carbon footprint than driving to the store to purchase the same game on a Blu-ray disc, according to findings published in the

PlayStation game console and Blu-ray disc
Journal of Industrial Ecology. For an 8.8-gigabyte PlayStation video game file — the average size of video games in 2010 — the resources required to produce, distribute, and dispose of Blu-ray discs are far less than the energy required to power servers, routers, and networks involved in downloading the game file, researchers say. The advantages of discs decrease as file sizes shrink, the analysis found, and for game files less than 1.3 gigabytes, downloading has a smaller carbon footprint than purchasing the game on Blu-ray. Between 2010 and 2013, however, game file sizes actually doubled for PlayStation4 and increased by 25 percent for PlayStation3. The analysis illustrates why it is not always true that digital distribution of media will have lower carbon emissions than distribution by physical means, the researchers say.

03 Sep 2014: 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.

22 Aug 2014: Drought in Western U.S.

The western U.S. has lost so much water during the ongoing severe drought that the land has sprung up by

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.

Using data from the European Space Agency's CryoSat 2 satellite from 2011 to 2014, the team created the most detailed maps to date of ice elevations across Antarctica and Greenland, accurate to a few meters in height. The results reveal that Greenland alone is losing ice volume by about 375 cubic kilometers per year, doubling since 2009, the scientists report. Ice loss in the West Antarctic Ice Sheet has increased by a factor of three over the same period. Combined, the two ice sheets are thinning at the highest rate observed since altimetry satellite records began about 20 years ago, the study found. Data show that East Antarctica is gaining ice volume, but at a moderate rate that doesn’t compensate the losses on the continent's other side.

18 Aug 2014: Recent Glacier Losses Are
Mostly Driven by Human Activity, Study Says

Roughly one-quarter of the global glacier mass loss between the years 1851 and 2010 can be attributed to

human activities, and that fraction increased to more than two-thirds between 1991 and 2010, according to research published in the journal Science. The study is the first to document the extent of human contribution to glacier mass loss, which is driven by both naturally caused climate factors, such as fluctuations in solar radiation, and anthropogenic influences. “In the 19th and first half of 20th century we observed that glacier mass loss attributable to human activity is hardly noticeable but since then has steadily increased,” the lead researcher said. The analysis was based on data from the recently established Randolph Glacier Inventory and included all glaciers outside of Antarctica. Changes in glaciers in the Alps and North America were particularly well documented and seem to be definitively influenced by human activities, the researchers said.

The developers hope the data will help authorities enforce existing fishing laws by, for example, developing flight maps for surveillance drones or strategically deploying enforcement authorities.

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.

10 Jul 2014: A Possible Advance in Fight
To Combat a Deadly Amphibian Fungus

Scientists have discovered that a certain kind of toad can acquire immunity to the deadly chytrid fungus, which has caused widespread mortality among amphibians worldwide. Reporting in Nature, the scientists say they have conferred immunity in oak toads to the chytrid fungus after repeatedly exposing them to the organism that causes the disease. The lead author of the study, Jason Rohr of the University of South Florida, said the discovery means it might be possible to confer immunity on entire communities of amphibians in the wild by lacing local water sources with dead versions of the fungus that could be absorbed by the amphibians. But Rohr said many questions remain, including how long immunity lasts, what concentration of released antigen would confer immunity, and whether such releases would harm other organisms. The chytrid fungus, Batrachochytrium dendrobatidis, attacks the skin of amphibians, thickening it and preventing the animals from absorbing water and vital salts.

the International Energy Agency (IEA). In 2013, networked devices consumed around 616 terawatt hours (TWh) of electricity, with most of that used in standby mode. Roughly 400 TWh — equivalent to the combined annual electricity consumption of the United Kingdom and Norway — was wasted because of inefficient technology. The problem will worsen by 2020, the agency projects, with an estimated $120 billion wasted as devices such as refrigerators, washing machines, and thermostats become networked. Much of the problem boils down to inefficient “network standby,” or maintaining a network connection while in standby mode. Most network-enabled devices draw as much power in this mode as when fully active, the report notes. Using today's best technology could cut energy consumption by 65 percent, the IEA said.

configurations, researchers report in Nature Communications. Wind farms lose roughly 10 to 20 percent of the potential energy they could harvest, and complex airflow patterns play the largest role in those energy losses. Studying airflow around large turbines, which can be more than 100 meters tall, is not feasible in lab settings, so scientists typically test smaller turbine models in wind tunnels and use tracer particles to visualize airflow patterns. Researchers from the University of Minnesota realized they could scale up their experiments to real-world conditions by using heavy snowfall during a blizzard to trace airflow patterns, as shown in this video. Their findings show that airflow patterns under real-world conditions differ from smaller-scale laboratory tests in important ways, and those differences should be taken into account when designing turbines and wind farms.

published in the journal Nature Climate Change. In the Mediterranean region, for example, the study shows that a grid-connected CSP network could provide 70 to 80 percent of current electricity demand, at no extra cost compared to natural gas-fired power plants. CSP could also feasibly meet energy demands in parts of southern Africa, according to researchers. CSP systems use mirrors or lenses to concentrate solar rays into a small area. The concentrated energy heats a liquid that produces steam to drive turbines, which means that the collected energy can be stored as heat and converted to electricity when needed — a major advantage over solar panels, which store energy much less efficiently.

The hidden formations more than a mile below the surface stand in stark contrast to the nearly flat, smooth exterior of the ice sheet and may accelerate its flow toward the sea, researchers say. Scientists had previously interpreted the irregular topography at the base of the ice as hills or mountains, but ice-penetrating radar revealed that the structures were made of ice rather than rock. Scientists from Columbia University explained that as meltwater at the bottom refreezes over hundreds or thousands of years, it radiates heat into the surrounding ice sheet, making it pick up its pace as the ice becomes softer and flows more easily. Greenland's glaciers appear to be moving more rapidly toward the sea as climate warms, but it's unclear how the refreezing process will influence this trend, researchers said.
