Organic carbon (OC) concentrations in the Zuoqiupu ice core for the monsoon (June–September) and nonmonsoon (October–May) seasons, and for the annual mean. Fig. 3 shows the Zuoqiupu data broken down by monsoonal and nonmonsoonal periods. The monsoonal period has lower BC and OC concentrations because of the high precipitation rate, but the source is unambiguously […]
On the Tibetan Plateau, temperatures are rising and glaciers are melting faster than climate scientists would expect based on global warming alone. A recent study of ice cores from five Tibetan glaciers by NASA and Chinese scientists confirmed the likely culprit: rapid increases in black soot concentrations since the 1990s, mostly from air pollution sources […]
(NASA/Goddard Space Flight Center) Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world’s largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. Temperatures […]
For decades, ‘development’ has meant allowing industrial parks to discharge untreated wastewater directly into millions of local residents’ water supplies. The Dong Nai River supplies water to some 15 million people in southern Vietnam, but that has not stopped callous companies from dumping so much toxic sludge in the river that scientists say it will […]
By Deepa Babington ROME (Reuters) – At least five whales have died after nine beached themselves off Italy’s southern coast, in what experts called a highly unusual event in Mediterranean waters. The whales, measuring up to 10 meters long and weighing several tones each, were found stranded off the coast of Puglia on Thursday, the […]
By Tim BradnerAlaska Journal of Commerce Coastal erosion isn’t the only climate-related problem confronting rural communities. Health officials now are concerned about food and water safety in northern villages as warming temperatures thaw ice cellars and melting permafrost increases the organic content in rivers, creating problems in village water treatment plants. As for erosion, it […]
By John Platt As if it weren’t bad enough that 99.9 percent of Asian vultures have been killed off in the past 20 years, now comes news that yet another potential man-made disaster waits in the wings. Millions of Asian vultures, particularly those in India, have died off over the last two decades after being […]
By Holli Riebeek In the ranking of the world’s proven oil reserves, Canada stands behind only Saudi Arabia. Canada possesses an estimated 178.6 billion barrels of crude oil accessible using current technology. Of this reserve, 174 billion barrels are in Alberta’s oil sand fields, which cover 140,200 square kilometers (54,132 square miles) of the province. […]
By Mark Schleifstein, The Times-PicayuneDecember 07, 2009, 3:13AM Frequent accidents at 10 of the state’s biggest refineries resulted in the release of millions of pounds of toxic chemicals into the air and millions of gallons of polluted water into state water courses between 2005 and 2008, according to a report to be released this morning […]
By Jeremy Hance, www.mongabay.comDecember 07, 2009 Canada’s tar sands have been internationally criticized as one of the world’s largest industrial sources of greenhouse gases, but the energy-intensive extraction of oil also has a less-noted impact on the local environment. A new study shows that the Alberta’s oil sands are likely releasing more PACs (polycyclic aromatic […]
