infectious diseases, an international team of researchers writes in the journal Trends in Parasitology
. Land use alterations, such as deforestation or agricultural changes, can affect the movement and distribution of people, animals, and insects that carry disease, the authors explain. One drone project, for example, tracked changes in mosquito and monkey habitats in Malaysia and the Philippines. By combining land-use information collected by drones with public health data, researchers there are hoping to better understand how changes in the environment affect the frequency of contact between people and disease vectors like mosquitoes and macaques, both of which can harbor the malaria parasite.

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
Baltoro Glacier in the Karakoram range
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.

Number of Megacities Has
Nearly Tripled Since 1990, UN Report Says
The number of urban areas with more than 10 million inhabitants — sometimes called "megacities" — has
nearly tripled in the last 24 years, jumping from 10 in 1990 to 28 in 2014, according to the latest UN report on world urbanization
. The total number of people living in megacities has grown from 153 million to 453 million during that period, the report says, and such areas now account for 15 percent of global GDP. Although densely populated urban areas can be environmental blights, innovations in efficient transportation have arisen from some major cities in Asia and Lagos, Nigeria, because those cities have invested heavily in public transit infrastructure, researchers say
E360 Video: Indonesian Villagers
Use Drones to Protect Their Forest
The villagers of Setulang in Indonesian Borneo have enlisted a new ally in their fight against the illegal clearing of their forests for oil palm plantations: aerial drones. The indigenous Dayaks manage the surrounding forest conservation area, and they are hoping the drones can help them ward off illegal oil palm operations and protect their land. “Dayaks and Drones
,” a video produced by Handcrafted Films, chronicles how the villagers teamed up with an Indonesian nonprofit to learn how to program and operate drones. Equipped with GPS technology, the small drones photograph the forest and monitor the area for illegal activities.

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.

World's Largest Coal Company
Plans Billion-Dollar Solar Project in India
Continuing its push to increase investment in renewable energy, India’s energy ministry is working with the
Gevra mine, operated by Coal India Limited
state-controlled coal mining company Coal India Limited — the largest coal mining operation in the world — to install solar power projects worth $1.2 billion. The company is in the process of selecting sites for solar plants, which are expected to have a combined total energy-generating capacity of 1,000 megawatts, the Times of India reports
. India currently has roughly 2,200 megawatts of grid-connected solar power capacity, so Coal India Limited's contribution would be a substantial increase
. When prime minister Narendra Modi took office earlier this year, he pledged to bring electricity to the homes of the nation's entire population of 1.2 billion — 400 million of whom lack any access to electricity — within the next five years, largely through solar projects.

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.

Smog in India Damaged
Enough Crops to Feed 94 Million, Study Says
Ground-level ozone, the main component of smog, damaged 6.7 million tons of Indian crops worth an
Smog in Delhi, India
estimated $1.3 billion in a single year, according to
a new study published in Geophysical Research Letters
. That's enough wheat, rice and other staple crops to feed 94 million people — roughly one-third of the country's impoverished population. Arising from a combination of vehicle emissions, cooking stoves, and industrial sources, plant-damaging ozone has left many of India's fast-developing cities among the most polluted in the world, according to the country's Air Monitoring Center. The number of vehicles there has nearly tripled in the past 10 years, rising from 50 million in 2003 to 130 million in 2013, and the country currently has no air quality standards to protect crops from ozone pollution. The researchers say the findings should be used to guide new ozone emission standards for the country.

Exporting Coal to Korea Could
Slash Emissions by 21 Percent, Analysis Says
Exporting U.S. coal to South Korean power plants could cut greenhouse gas emissions by 21 percent compared to burning it at less efficient U.S. plants, according to
researchers at Duke University
. The strategy could also generate more than $25 billion in economic activity in the U.S. and cut emissions of sulfur dioxide, nitrogen oxide, and particulate matter, the researchers say. For those benefits to occur, however, U.S. plants would need to replace the exported coal with natural gas, and South Korea must use the imported coal to replace dirtier sources of coal. South Korea's coal-fired power plants are newer and significantly more efficient than those in the U.S. — efficient enough to offset emissions associated with shipping the coal across the globe, the researchers say. However, they also caution that further studies are needed to assess the scenario's full environmental impacts, including water use, land use, and the degradation of vital habitats.

continent of Australia — China's National Energy Administration reports
. The country now has 23 gigawatts of solar power installed, which is nearly twice that of the United States. China, the world's largest carbon emitter, has set a goal of 35 gigawatts of installed solar power by the end of next year. The nation's push toward solar energy will include distributed solar, such as rooftop and ground-mounted installations near homes and municipal buildings, Chinese officials say, and the government could announce distributed solar incentive programs later this month, Bloomberg News reports. Renewable energy, especially solar, has become a high priority for the Chinese government as major cities and industrial areas have experienced choking air pollution. Earlier this week, officials announced that Beijing would ban coal use by 2020.

India Doubles Coal Tax to
Fund Ambitious Clean Energy Initiatives
India's finance minister has doubled the tax on coal imported to or mined in the country, raising the tariff from $0.83 to $1.67 per metric ton, with plans to use the revenue to fund a host of renewable energy projects over the next decade, Clean Technica
reports. The revenue will be added to the National Clean Energy Fund, which was established to provide low-cost financing for renewable energy projects. The fund's scope will be expanded to include environmental projects as well as clean energy research and development, including a national wind energy program, four major solar power projects, and an initiative that aims to establish transmission corridors for distributing electricity from renewable energy sources. The revenue will also be used to fund a new, separate ministry focused on cleaning the heavily polluted Ganges River. The tax could raise as much as $1.2 billion in the first year, according to estimates.

limits. The app, developed by the Beijing-based Institute of Public and Environmental Affairs (IPE), uses data from some 15,000 factories throughout China that are now required to report emissions to local officials and the Environment Ministry on an hourly basis. The government made all the data public at the beginning of this year, but now, for the first time, those data are available in one place through IPE's app and website. The app allows users to check air quality data for 190 cities and share air emissions data from polluters in those areas. Factories producing excessive emissions are shown in red. "If the air quality is bad you can switch (to the factory map) and see who is in your neighborhood," IPE's senior project manager explained.

India's New Prime Minister
Plans To Make A Major Push on Solar Energy
India's new government plans to bring electricity to the homes of its entire population of 1.2 billion within the next five years, largely through solar panel installations,
Bloomberg News reports
. Although nearly 400 million Indians do not have access to electricity, newly elected prime minister Narendra Modi, who won an overwhelming victory in last week's national vote, has pledged to enable every household to run at least one light bulb by 2019. If all goes well, household solar projects would allow every home to run two light bulbs, a solar cooker, and a television, one of Modi's energy advisers said. The plan follows an unfulfilled pledge from the previous administration to bring electricity to all homes by 2012. Modi, who pioneered India's first incentive program for large-scale solar projects when he was chief minister of Gujarat state, has made expanding solar a top priority because it has the potential to create jobs and supply power to millions of households, many of which are scattered throughout rural areas and not connected to the grid
. "We look upon solar as having the potential to completely transform the way we look at the energy space," said the energy adviser.

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.

Five Kamchatka Volcanoes
Erupt Simultaneously, NASA Images Show
A NASA satellite passing over Russia's Kamchatka Peninsula this week photographed five simultaneous volcanic eruptions
. The erupting volcanoes, from north
to south, are Shiveluch, Klyuchevskaya, Bezymianny, Kizimen, and Karymsky. Karymsky, a 1,536-meter (5,039-foot) peak that has erupted regularly since 1996, is the most active of the five. The tallest, Klyuchevskaya, is 4,750 meters (15,580 feet) high. Of the planet's roughly 1,550 volcanoes that have erupted in the recent geologic past, 113 are found on the Kamchatka Peninsula, in Russia's far northeast, according to NASA. Forty volcanoes on Kamchatka are active, meaning they are either erupting now or capable of erupting at any time. Kamchatka's fiery landscape is driven by plate tectonics: The Pacific Plate is slowly colliding with and sliding beneath the Okhotsk Plate. As the Pacific Plate melts, magma migrates up toward the surface, causing volcanic eruptions.

Newfound Atmospheric 'Hole'
Threatens Polar Ozone Layer, Scientists Say
Researchers have discovered
a large opening in the Earth's atmosphere that is enabling pollutants to rise
Pacific atmosphere hole an elevator to the stratosphere
into the stratosphere and destroy ozone. The hole, which is in a part of the lower atmosphere called the "OH shield," is several thousand kilometers long and is centered over the tropical west Pacific Ocean. It's relatively close to Southeast Asia, a region with a booming population and rapidly increasing air pollution. The hole is a major concern because the OH shield usually scrubs air of chemical compounds emitted near the ground before they can reach the stratosphere, where those compounds can persist for long periods of time, reacting with and destroying ozone, say researchers at Germany's Alfred Wegener Institute who identified the hole. The newly discovered phenomenon acts as a sort of elevator, researchers say, drawing chlorofluorocarbons, sulfur dioxide, and other contaminants straight up to the stratosphere and bypassing the OH shield scrub.

Consumer Products Giants
Commit to Deforestation-Free Palm Oil
Two major consumer products companies — General Mills and Colgate-Palmolive — have committed
to using palm oil in their products that does not come from lands cleared from tropical forests, adding to the wave
of corporations that have pledged measures to protect southeast Asian rainforests. The consumer giants' new policies go beyond standards set by the industry's main certification body and include provisions to protect wildlife-rich rainforests, carbon-dense peatlands, and the rights of local communities. Environmental groups are welcoming the commitments, though some believe the companies' pledges should go further. The Union of Concerned Scientists questions General Mills' definition of "high carbon stock" forests, while Greenpeace is urging Colgate-Palmolive to move implementation up to 2015 from 2020. Environmental groups are hopeful that new commitments will pressure Proctor & Gamble, the last remaining consumer products giant without a similar pledge, to adopt deforestation-free palm oil policies.

Nine Chinese Cities Outpaced
Beijing in Air Pollution in 2013, Report Says
China's air pollution problems are more severe and widespread than previously thought, with nine cities experiencing more days of extreme air pollution than Beijing in 2013, according to
a new analysis by Greenpeace's Energy Desk. Fine particulate (PM2.5) pollution plagued dozens of cities and millions of people in China — most of them outside of Beijing, although the Chinese capital captured the most air pollution headlines last year. The city of Xingtai, southwest of the capital, fared worst, with 129 days of emergency air pollution — more than doubling Beijing's 60 days. More than half of the cities in the top 10 are in Hebei province south of Beijing, where many steel, cement, and coal-fired power plants are located. "There are now millions of Chinese people living in cities with air pollution above emergency levels for a third of the year, while other urban areas have gone a whole 12-month period with hardly any days of good-quality air," said a member of Greenpeace's East Asia climate and energy campaign. Beijing had only 13 days ranked as "good" on the U.S. air quality scale, along with one day considered "beyond index," or off the pollution scale.

Arsenic Remediation Project
Will Begin Decontaminating Water in India
New technology that removes arsenic from drinking water is set to be deployed on a large scale in India, according to
researchers from Lawrence Berkeley National Laboratory and an India-based water technology company. The device removes arsenic by passing electricity through steel plates submerged in a water reservoir. The electric current causes the plates to rust more quickly than they would under normal conditions, and the rust chemically binds to arsenic in the water and sinks to the bottom of the reservoir. The precipitated sludge can be removed from the tank, rendering the water safe to drink. Notoriously high levels of arsenic, a tasteless and odorless contaminant, naturally occur in groundwater sources in India, Bangladesh, and even California's Central Valley. Long-term exposure can cause cancer and severe damage to organs. A commercial plant is set to begin operations in West Bengal, India, this year and researchers estimate the drinking water can be sold for as little as eight cents per gallon.

Maps Show Tropical Corridors
Important to Wildlife As Climate Changes
A new set of maps
highlights the importance of habitat corridors in helping wildlife deal with the effects of climate change and deforestation. The series of maps shows more than 16,000 habitat corridors
— swaths of
land that connect forests or protected areas and allow animals to move between them — in tropical regions of Africa, Southeast Asia, and South America. High-resolution data on biodiversity, endemism, and vegetation density allowed the researchers, led by Patrick Jantz of the Woods Hole Research Center, to determine which corridors are most important for maintaining biodiversity under changing climate conditions. The maps also highlight which corridors are most important for sequestering carbon and averting carbon emissions associated with deforestation. Researchers hope the findings will help guide wildlife protection plans and serve as a framework prioritizing the conservation of habitat corridors.

China Approves Major
Increase in Huge Coal Mining Projects
In 2013, the Chinese government approved 15 large coal mining projects
that will produce more than 100 million new tons of coal a year. The expansion will lead to a 2 to 3 percent growth in coal production over the next several years, even as the country announced moves to reduce the severe air pollution
choking major cities such as Beijing. Chinese officials will increase coal production while reducing pollution in population centers by closing outdated coal plants and creating huge “coal bases” that will mine and burn coal in remote regions of northwestern China, such as Inner Mongolia. Those bases, which will cost $8.9 billion to build, will generate electricity that will be transferred over an improved electricity grid to cities in China’s central and eastern regions. Deng Ping, an environmental campaigner with Greenpeace, said the scale of the new coal bases is unprecedented for China, adding, “Despite the climate change pressure, water resource scarcity, and other environmental problems, the coal industry is still expanding fast in northwest China.”

China Crushes Six Tons
Of Ivory to Stem Elephant Poaching
In an effort to stem elephant poaching, Chinese authorities have crushed six tons of confiscated ivory
, the first such effort in the country's history. Coordinated by the State Forestry Administration and the General Administration of Customs, the event was widely publicized and aimed at spreading awareness in China of the scale of the global poaching crisis. Conservation
groups consistently name China as a major driver of elephant poaching, as the country's growing middle class has increasingly sought to buy ivory ornaments and ivory-based medicinal therapies, which have no scientific or medical basis. The six tons of ornaments and tusks that were crushed represent only a fraction of China's ivory stockpile, which is probably more than 45 tons, the Wildlife Conservation Society (WCS) estimates. Still, many conservation groups are applauding China's efforts. "This destruction of ivory by China is a symbol of the government's growing responsiveness to the ivory crisis," the WCS said.

Australian Coal Projects
Threatened by Drop in Demand From China
Major Australian coal projects risk losing value due to falling demand from China, where leaders are increasingly concerned about growing public anger over severe air pollution, a new analysis from Oxford University
has found. Future coal mining projects are vulnerable to being "stranded" by a range of policy changes from the Chinese government, including environmental regulation, carbon pricing, investment in renewable energy, and energy efficiency, the report said. One expert told The Guardian
that global investors are already questioning the prudence of financing new fossil fuel projects
. Backers of a handful of upcoming Australian coal projects "should seek clarity" on the associated costs, the Oxford analysis warns. It also cautions that Australian state governments could suffer if projects are mothballed or abandoned. Of particular concern are two mega-mines supported by Australia's Prime Minister Tony Abbott
slated for development in Queensland. Once running at full capacity, the two projects combined would produce enough coal to emit more than 70 millions tons of CO2 a year.

Final Shipment of Russian
Warhead Uranium Set to Reach U.S. Today
A U.S. nuclear storage facility today will receive the final shipment of decommissioned nuclear warheads from Russia, NPR reports
. Since 1993 the Russian uranium has been generating 10 percent of all electricity consumed in the U.S., part of a deal struck with the former Soviet state when its nuclear industry, crippled by arms reduction agreements, was struggling to make
Russian uranium ready for shipment to U.S.
ends meet. Negotiations began when a U.S. official visited Russia in the early 1990s and found bomb-grade uranium from thousands of decommissioned warheads lying around in crumbling storage facilities. Concerned that the radioactive material was unsecured and vulnerable to theft, the U.S. asked to buy it. Russian officials reluctantly agreed to convert roughly 500 tons of bomb-grade uranium into nuclear fuel and sell it to the U.S. Experts say it was a win-win scenario: Russia made a substantial profit ($17 billion), U.S. power plants could buy the uranium at a good price, and 20,000 bombs' worth of radioactive material was converted into relatively clean electricity. The deal will go down in history as one of the greatest diplomatic achievements ever, one expert told NPR.

Chinese State Media
Criticized for Touting Benefits of Smog
For Chinese citizens worried about smog, which has been blanketing major cities and smashing air pollution records recently, China's state media has some advice: Look on the bright side. State broadcaster CCTV and a Communist Party tabloid, Global Times
, yesterday published editorials
attempting to put a positive spin on China's air pollution crisis. The state-run outlets said smog has military benefits because it can interfere with the guidance systems of foreign missiles, as well as personal benefits such as bolstering Chinese citizens' sense of humor, making them more united, more sober, better informed, and more equal because smog "affected the lungs of both rich and poor," The Telegraph
reports. Internet commenters and other media outlets, including several state-run publications, were outraged. "Is the smog supposed to lift if we laugh about it?" asked the official publication Beijing Business Today
. The pro-smog pieces have both been deleted from the publications' websites.

China Doubles Pace
Of Renewable Energy Installation in 2013
Over the past 10 months China has added renewable energy sources to its power grid at double the pace of 2012, according to its National Energy Administration (NEA). The renewable energy push, part of a massive effort to cut air pollution in China's large cities, has added more than 36 gigawatts of clean energy capacity
Shanghai, Dec. 3, 2013
so far this year, Bloomberg News reports
. Hydroelectric power grew by 22.3 gigawatts in the first 10 months of 2013, new nuclear energy installations totaled 2.2 gigawatts, solar 3.6 gigawatts, wind 7.9 gigawatts. China's solar energy capacity could triple from 2012 levels to 10 gigawatts by the end of the year, while wind and nuclear power capacity could increase by 22 and 17 percent, respectively, the NEA said. That should offer some relief from China's choking air pollution. In Shanghai, schoolchildren were ordered indoors today
as air pollution reached extremely hazardous levels, exceeding World Health Organization health guidelines for fine particulate matter by 24 times.

Wide Mangrove Destruction
Is Documented Along Coast of Myanmar
Rapid agricultural expansion destroyed nearly two-thirds of the mangrove forests
in Myanmar’s Ayeyarwady Delta between 1978 and 2011, increasing the region’s vulnerability to cyclones and typhoons, according to a new study. Using remote sensing imagery
and field data, researchers from Myanmar and Singapore said that the dense mangrove cover in the Ayeyarwady Delta declined from 2,623 square kilometers to 1,000 square kilometers in that 33-year period. The main cause was agriculture expansion and the researchers said that if rates of destruction continue at their current pace the delta’s mangroves could be completely deforested by 2026. Reporting in the journal Global Environmental Change
, the scientists said the loss of mangroves in the Ayeyarwady Delta could put the region at greater risk of major storms such as Cyclone Nargis, which killed 138,000 people in Myanmar in 2008. But the researchers said the destruction could be slowed if Myanmar creates coastal protected areas.

China Set to Open
World's Second Largest Carbon Market
China is in the midst of launching seven carbon markets, the largest of which will open next month in Guangdong
, the country's most populous province. The carbon markets are a key element of China's plan to cut carbon emissions by up to 45 percent per unit of GDP by 2020. The Guangdong carbon permitting scheme will cap 2013 emissions at 350 tons for 202 companies in the heavily industrialized province. Twenty-nine million permits will be auctioned in the market this year and next, which will be the world's second largest carbon market after the European Union's, dwarfing carbon markets in Australia and California. In 2015 the number of permits auctioned will more than triple, officials said. Shanghai's carbon market launched yesterday and a similar market, about a quarter of the size of Guangdong's, is set to open in Beijing tomorrow. China's seven carbon markets together will regulate roughly 700 to 800 million tons of CO2 annually, roughly equal to the annual emissions of Germany.

Low-Income Solar Project
Is Recognized at U.N. Climate Talks
An Australia-based solar start-up company was recognized at the U.N. climate change talks in Warsaw for its work replacing highly polluting kerosene lamps with solar lighting in low-income regions of India. The company, Pollinate Energy, trains members of local communities to install household solar-powered lights in India's slums, where families often rely on kerosene for lighting. So far the project has installed solar-powered lighting systems for 10,000 people in 250 of Bangalore’s slum communities, in turn saving 40,000 liters of kerosene and 100,000 kilograms of carbon emissions, RenewEconomy reports
. The solar lighting systems are cheaper to operate than kerosene lamps and are less polluting and dangerous than kerosene, which can cause house fires and severe burns. The nonprofit project started in Bangalore — home to some of India's worst slums — as a way for children to do schoolwork after sunset. Pollinate Energy trains local installers to distribute and install the lighting systems as micro-entrepreneurs, which they call "pollinators."

Groundbreaking Mapping Project
Depicts Forest Change Around the Globe
Scientists from Google, U.S. universities, and federal agencies have for the first time produced a high-resolution global map showing in striking detail the extent of deforestation across the globe.
The project — which relied heavily on expertise from the computing
center Google Earth Engine — documents a loss of 888,000 square miles of forest between 2000 and 2012, along with a gain of 309,000 square miles of new forest. The rate of deforestation is equal to losing 68,000 soccer fields of forest every day for the past 13 years, or 50 soccer fields every minute, says the World Resources Institute
. Brazil, once responsible for a majority of the world's tropical forest loss, is now the global leader in scaling back forest destruction, cutting its deforestation rate in half over the past decade, researchers report in Science
. Over the same period, Indonesia has more than doubled its annual rate of forest loss, despite a supposed 2011 Indonesian government moratorium on new logging licenses.
