Using satellite imagery and topographic maps, a team of scientists found that the majority of glaciers on Everest, the world’s tallest mountain, and in the surrounding Sagarmatha National Park are retreating at an accelerating rate. In the last 50 years, the snowline in the Everest region has shifted up by an average of 590 feet (180 meters), said Sudeep Thakuri, a Ph. D. student at the University of Milan and leader of the research team, which presented its findings at a conference in Cancún, Mexico. Because glaciers are melting faster than they are being replenished, researchers say, rock and debris that were previously hidden under snow are now exposed and absorbing heat.

that coincides with the rise of industrial fishing. In tests conducted on petrel bones collected over three decades in the Hawaiian islands, a team of scientists found that the bones from 4,000 to 100 years ago contained higher ratios of nitrogen-15 and nitrogen-14 isotopes than the more recent bones, suggesting that the earlier birds ate bigger prey before changes in the food web composition of the Northeast Pacific. According to the scientists, the nitrogen ratio started to decline in the decades after the early 1950s, when industrial fishing started to extend beyond the continental shelves. “Our bone record is alarming because it suggests that open-ocean food webs are changing on a large scale due to human influence,” said Peggy Ostrom, a zoologist at Michigan State University and co-author of the study, published in the Proceedings of the National Academy of Sciences.

03 May 2013: Seawater Energy Technology
Is Focus of Pilot Project in China

The U.S. defense and aerospace giant, Lockheed Martin, is partnering with a major Chinese company to build a pilot project off the southern Chinese coast that will use temperature differentials between the deep and shallow ocean to generate electricity. The technology, known as ocean thermal energy conversion (OTEC), uses the heat from warm surface waters to boil a fluid with a low boiling point, such as ammonia, producing steam to drive turbines. Colder water is then pumped from 2,500 to 3,000 feet under the sea, which condenses the steam into liquid; the liquid can then be boiled again to produce more steam and power. Lockheed Martin and its Chinese Partner, the Beijing-based Reignwood Group, said their project — the largest OTEC plant ever built — will produce 10 megawatts of power when it opens in 2017, enough to provide electricity for a large, planned resort that Reignwood is building.

02 May 2013: Five Southeast Asian Nations
Have Lost One-Third of Forests in 33 Years

Thailand, Vietnam, Laos, Cambodia, and Vietnam have lost one-third of their forests since 1980 and could be left with only 10 to 20 percent of their original forest cover by 2030, according to a review of satellite data by WWF. The conservation group warned that if present trends continue only 14 percent of the greater Mekong region’s remaining forest cover will consist of contiguous habitat capable of sustaining viable populations of many wildlife species, such as tigers and Asian elephants. The WWF researchers calculated that since 1980, Thailand and Vietnam have lost 43 percent of their forests, Laos and Burma have lost 24 percent, and Cambodia has lost 22 percent. Since 1973, areas of core, undisturbed forest — defined as having at least 3.2 square kilometers of uninterrupted forest — have declined from 70 percent to 20 percent of the region. Peter Cutter, landscape conservation manager with WWF-Greater Mekong, said the region is at a crossroads and that to preserve its remaining forests and biodiversity it must expand protected areas and better safeguard those that already exist.

25 Apr 2013: Metal Demand Could Increase
Nine-Fold as Developing Economies Grow

Global demand for metals could increase nine-fold in the coming years as the world’s developing economies continue to grow, a trend that could have profound negative environmental impacts, a new UN report says. As populations in these countries continue to adopt modern technologies, and nations increasingly construct metal-intensive renewable energy projects, the need for raw metal materials will likely be three to nine times larger than the current global demand, said Achim Steiner, executive director of the United Nations Environment Program (UNEP). While the current demand is typically met by mining for more metals, large-scale mining operations can have adverse environmental consequences, and the supply of some rare earth metals is running low. Saying that there is an urgent need for a more sophisticated approach to recycling the planet's increasingly sophisticated products, the UN suggested that mining companies be enlisted to help sort out valuable metals when the products reach the end of their usefulness.

02 Apr 2013: Air Pollution Linked to
1.2 Million Chinese Deaths in 2010

Air pollution contributed to the premature deaths of more than 1.2 million people in China in 2010, or about 40 percent of early deaths worldwide caused by dirty air, according to a newly released analysis. The findings, based on data from a study on the distribution and causes of death globally, categorized “ambient particulate matter pollution” as the fourth-leading factor in premature deaths in China, behind dietary risks, high blood pressure, and smoking. Worldwide, air pollution was the seventh-leading cause of premature death, contributing to 3.2 million deaths, according to the study. While the study was published in The Lancet, a UK-based medical journal, the summary of China statistics was reported at a forum in Beijing, the New York Times says. The findings come as public outrage grows in China as residents of many cities endure choking air far in excess of safe levels.

26 Mar 2013: China’s Utility Giants
Vulnerable to Water Scarcity, Report Says

China’s five largest power utilities, which depend on water-intensive, coal-fired stations to generate electricity, are vulnerable to water supply disruptions because they are centered in the country’s water-scarce northern regions, a new report says. According to Bloomberg New Energy Finance, the five power generators — Huaneng, Datang, Huadian, Guodian, and China Power Investment — operate hundreds of gigawatts of thermal plants in the industrial northeast, where water resources are increasingly strained. Eighty-five percent of China’s power-generating capacity is in water scarce regions, said Maxime Serrano Bardisa, one of the report’s coauthors. The report said that major technical and policy shifts will be required to avert serious disruptions, including the addition of systems that use less water, such as closed-cycle or air-cooled systems. Such improvements could cost the utilities $20 billion in retrofit costs, the report said.

22 Mar 2013: Expansion of Chinese City Poses
Environmental and Safety Risks, Critics Say

An ambitious plan to expand the western Chinese city of Lanzhou into a regional industrial hub is raising concerns over what critics call lax government oversight of the environmental and safety impacts, including worries that it will siphon huge amounts of water from an already parched region and devastate nearby mountains. Lanzhou, the capital of Gansu Province, is a city of 3.6 million and a gateway to Tibet and the Xinjiang region. It is known as one of the most polluted cities in China, and now the government is working to expand the city’s footprint by at least 70 percent, according to Caixin Online. That expansion involves the flattening of mountaintops, and the additional 1 million people and increased industrial activity will draw water from the already polluted and over-stressed Yellow River. Opponents of the plan say buildings will also be constructed on loose soil that will be vulnerable to collapse. “It was a rash decision to begin construction on the new city before receiving environmental approvals or seeking opinions from the Lanzhou public,” said Zhao Zhong, a local activist.

20 Mar 2013: High-Speed Trains Provide
Environmental, Social Benefits, Study Says

Bullet trains fuel real-estate booms, improve quality of life, reduce air pollution and traffic congestion, and provide a “safety valve” for crowded cities, especially in the developing world, according to a study by Chinese and U.S. economists. The study was based on China’s rapidly expanding high-speed rail network, but the researchers said the benefits experienced there would be similar for California’s proposed high-speed rail system. Bullet train systems connecting China’s largest cities to nearby smaller cities have made these “second tier” cities more attractive for workers and alleviated traffic congestion and pollution in megacities, according to the study, carried out by economists at Tsinghua University and the University of California, Los Angeles. The study found that the trains created a new category of exurbs within 60 to 470 miles of urban centers such as Beijing, Shanghai, and Guangzhou, helping keep people from moving to already crowded megacities. The study was published in the online version of the Proceedings of the National Academy of Sciences.

22 Feb 2013: A 1.5 C Temperature Rise Could
Release Greenhouse Gases in Permafrost

A global temperature increase of 1.5 degrees Celsius could unleash more than 1,000 gigatons of carbon and methane currently trapped beneath Siberian permafrost and accelerate global climate change, a new study says. In a study conducted in a frozen cave in Siberia, researchers analyzed stalactites and stalagmites which, since they form only when rainwater and snowmelt drip into the caves, provide a glimpse into 500,000 years of changing permafrost conditions. According to their findings, records of an especially warm period 400,000 years ago suggest that a 1.5-degree increase compared to current temperatures would trigger the thawing of permafrost far north of its existing southern boundary. And since permafrost covers 24 percent of the exposed land surface in the Northern Hemisphere, significant thawing could release huge amounts of methane and carbon dioxide, said Anton Vaks, a scientist at Oxford University and lead researcher on the study, published in Science Express. In addition to the effects the loss of permafrost could have on climate, it could have major regional implications, affecting roads, railways, and natural gas facilities built on the frozen landscape.

21 Feb 2013: Chinese Air Pollution Triggers
Steep Rise in Nitrogen Deposition

A spike in Chinese air pollution over the last three decades has caused a 60 percent increase in the levels of nitrogen pollutants that ultimately end up back on the nation’s land and in its water, a new study has found. In an analysis of 270 monitoring sites across the country, researchers found that the annual deposition of nitrogen, as measured in precipitation, had increased from 13.2 kilograms per hectare in 1980 to about 21.1 kilograms per hectare in 2010. Scientists say so-called nitrogen deposition occurs when nitrogen in the atmosphere is washed back to the planet’s surface by rain and snow in the form of pollutants such as nitrates and ammonium. Elevated nitrogen levels can trigger harmful ecological effects, from soil acidification to feeding algae blooms. According to the study, published in Nature, leaves of herbaceous and woody plants absorbed 33 percent more nitrogen in 2010 than in 1980, while rice, wheat, and maize crops on unfertilized fields had a 16 percent increase. The spike in pollution levels has been driven by an increase in industrial emissions, agricultural uses, and transportation.

15 Feb 2013: Meteor Strike in Siberia
Rains Down Debris and Injures 1,000

A 10-ton meteor broke apart 20 to 30 miles above the ground in western Siberia, raining chunks of debris over a large area, causing a powerful boom that damaged buildings across a vast territory, and injuring more than 1,000 people, mostly from shattering glass. The Russian Academy of Sciences said the meteor, known as a bolide, streaked through the earth’s atmosphere near the Ural mountain city of Chelyabinsk, 950 miles east of Moscow, around 9 a.m. local time Friday. It lit up the sky with a fireball that could be seen for hundreds of miles and that was captured on video by scores of observers. Pieces of the disintegrating meteor fell into a lake about 50 miles west of Chelyabinsk, and scientists and local officials said the damage and injuries could have been far worse had chunks of the meteor fallen on Chelyabinsk itself. As it was, the meteor strike shattered windows, TV sets, and dishes across a wide area, which caused most of the injuries. Most meteors that strike Earth disintegrate in the atmosphere, but this meteor was made of exceptionally hard material and did not fully burn up as it approached Siberia, scientists said.

28 Jan 2013: Megacities Alter Weather
Across Long Distances, Study Says

Heat generated in major metropolitan areas is altering the character of the jet stream and other atmospheric systems, at times affecting the weather thousands of miles away, a new study says. Writing in the journal Nature Climate Change, a team of scientists reports that so-called “waste heat” produced from buildings, cars, and other sources is altering weather patterns and increasing winter temperatures across large areas of North America and northern Asia by as much as 1 degree C (1.8 degrees F). In parts of Europe, however, the changes to atmospheric circulation are causing temperatures to fall by as much as 1 degree C., the study found. “Although much of this waste heat is concentrated in large cities, it can change atmospheric patterns in a way that raises or lowers temperatures across considerable distances,” said Aixue Hu, a scientist at the National Center for Atmospheric Research and one of the lead authors of the study. According to the study, this phenomenon is different than the so-called “heat island effect,” in which cities are warmer than surrounding areas as a result of heat collected and re-radiated by pavement, buildings, and other urban features.

Satellite measurements of nitrogen dioxide concentrations are a good indicator of air quality since NO2 is produced by the same fossil fuel-burning processes that also send sulfur dioxide and aerosols into the atmosphere, such as from vehicles, industrial sites, and power plants. The high concentrations of NO2 shown in the NASA map, based on measurements from Jan. 1 to 8, coincided with reports from several cities of hazy skies, unhealthy air quality, and elevated cases of lung ailments.

18 Dec 2012: Coal May Rival Oil As
World’s Top Energy Source by 2017, IEA Says

Coal could rival oil as the world’s largest energy source within five years as consumption continues to climb in most regions of the world, a trend that could have profound effects on the climate, the International Energy Agency (IEA) says. While coal consumption is expected to decline in the U.S., where it increasingly has been displaced by ample supplies of natural gas, that reduction in U.S. coal burning has helped drive down coal costs globally. According to the IEA’s annual Medium-Term Coal Market Report, the world will burn about 1.2 billion more tons of coal annually by 2017 than it does today. The surge in coal consumption will be driven largely by China and India, with China projected to pass the rest of the world in coal demand within five years, and India predicted to pass the U.S. as the world’s second-biggest coal consumer. Without a high carbon tax, the report says, only competition from cleaner natural gas will reduce coal demand.

One panoramic view of a public housing project illustrates the height of the tsunami wave, which ruined everything up to the fourth floor of the building. Another image, of the condemned Ukedo Elementary School, shows the collapsed auditorium floor beneath the banner of a graduation ceremony that was never held. The images were added to Google’s “Memories for the Future” website, which is chronicling the affected areas from before and after the tsunami.
