By MATTHEW BROWN (AP)17 August 2010 WYODAK, Wyo. — Utilities across the country are building dozens of old-style coal plants that will cement the industry’s standing as the largest industrial source of climate-changing gases for years to come. An Associated Press examination of U.S. Department of Energy records and information provided by utilities and trade […]
By Steve Cole, NASA Headquarters, WashingtonAug. 19, 2010 WASHINGTON — Global plant productivity that once was on the rise with warming temperatures and a lengthened growing season is now on the decline because of regional drought according to a new study of NASA satellite data. Plant productivity is a measure of the rate of the […]
By Kelsey Abbott and Justin Ries 8/8/10 07:42 pm The Gulf of Maine is and always has been an essential part of the coastal New England economy. Throughout history, the bounty of the Gulf of Maine has fluctuated due to fishing pressures, technology and species’ popularity. As these changes have affected some parts of the […]
(Rice University) A new study by geochemists at Rice University finds that damming and other human activity has completely obscured the natural carbon dioxide cycling process in Texas’ longest river, the Brazos. “The natural factors that influence carbon dioxide cycling in the Brazos are fairly obvious, and we expected the radiocarbon signature of the river […]
By Staff WritersHelsinki, Finland (SPX) Jul 27, 2010 The terrestrial biosphere regulates atmospheric composition, and hence climate. Projections of future climate changes already account for “carbon-climate feedbacks”, which means that more CO2 is released from soils in a warming climate than is taken up by plants due to photosynthesis. Climate changes will also lead to […]
This figure shows changes in ocean carbon dioxide levels (measured as a partial pressure) and acidity (measured as pH). The data come from two observation stations in the North Atlantic Ocean (Canary Islands and Bermuda) and one in the Pacific (Hawaii). Dots represent individual measurements, while the lines represent smoothed trends. Measurements made over the […]
By JOHN VIDALAugust 10, 2010 Giant hydroelectric dams being built or planned in remote areas of Brazil, Ethiopia, Malaysia, Peru and Guyana will devastate tribal settlements by forcing people off their land or destroying hunting and fishing grounds, according to a report by Survival International. The first global assessment of its kind suggests 300,000 indigenous […]
By Alister Doyle, Environment Correspondent Wed Aug 11, 2010 12:04pm EDT OSLO (Reuters) – Some of Russia’s smog-causing peatland fires are likely to burn for months, part of a global problem of drained marshes that emit climate-warming greenhouse gases, experts said on Wednesday. Novel carbon markets could offer a long-term fix for peat bogs, from […]
By Richard Galpin6 August 2010 The thick blanket of smog that has shrouded Moscow as peat fires continue to burn just outside the city has worsened. The smog has disrupted air traffic at two international airports in Moscow – Domodedovo and Vnukovo. Many Russians are wearing masks as the temperature rises close to 40C (104F). […]
Provided by American Physiological SocietyAugust 5, 2010 Human impact is causing lower oxygen and higher carbon dioxide levels in coastal water bodies. Increased levels of carbon dioxide cause the water to become more acidic, having dramatic effects on the lifestyles of the wildlife that call these regions home. The problems are expected to worsen if […]
