Boulder CO (SPX) Jul 21, 2009 – All reservoirs along the Colorado River might dry up by mid-century as the West warms, a new study finds. The probability of such a severe shortage by then runs as high as one-in-two, unless current water-management practices change, the researchers report. The study’s coauthors looked at the effects […]
Growing Deserts, Growing Dust Storms Carbon dioxide emitted in China raises carbon dioxide levels everywhere. Dust and particulate pollution tends to have its greatest impacts locally, but it can cast a wide net too. New research on a massive 2007 dust storm that began in the Taklimakan desert of Xinjiang, reveals a cloud of dust […]

San Joaquin Valley farms are laying off workers and letting fields lie fallow as their water ration falls. By Alana Semuels Reporting from Mendota, Calif. — Water built the semi-arid San Joaquin Valley into an agricultural powerhouse. Drought and irrigation battles now threaten to turn huge swaths of it into a dust bowl. Farmers have […]
Shangri-La is in trouble. According to an article by Stephen Faris in Foreign Policy and the IPCC, the Himalayan glacier in the Kashmir province that provides 90 percent of Pakistan’s water for agricultural irrigation will disappear by 2035 as a consequence of climate change. Appropriately titled “The Last Straw,” the article reviews water conflicts exacerbated […]
By Slim Allagui – Thu Jul 9, 2:13 am ET NUUK (AFP) – From his trawler that motors along the Nuuk fjord, fisherman Johannes Heilmann has watched helplessly in recent years as climate change takes its toll on Greenland. Global warming is occurring twice as fast in the Arctic as in the rest of the […]
Climate change is rapidly expanding the size of the world’s tropical zone, threatening to bring disease and drought to heavily populated areas, an Australian study has found. Researchers at James Cook University concluded the tropics had widened by up to 500 kilometres (310 miles) in the past 25 years after examining 70 peer-reviewed scientific articles. […]
By Michael Perry SYDNEY (Reuters) – Mounting loss of seagrass in the world’s oceans, vital for the survival of endangered marine life, commercial fisheries and the fight against climate change, reveals a major crisis in coastal ecosystems, a report says. A global study of seagrass, which can absorb large amounts of planet-warming carbon dioxide, found […]
By David Fogarty, Climate Change Correspondent, Asia SINGAPORE (Reuters) – Staples such as cassava on which millions of people depend become more toxic and produce much smaller yields in a world with higher carbon dioxide levels and more drought, Australian scientists say. The findings, presented on Monday at a conference in Glasgow, Scotland, underscored […]
Increased melting of the large polar ice sheets contributes to the observed increase in sea level. Observations of the area of the Greenland ice sheet that has been at the melting point temperature at least one day during the summer period shows a 50% increase during the period 1979 to 20086 (see figure). The Greenland […]
