Most people are familiar with automobile air emissions. Perhaps one day there will only be electric cars and no car air emissions. But there are many on other engines in use by commercial and industrial operations that may cause air emissions. In general these are called reciprocating internal combustion engines (RICE). On February 17, 2010,…

Overuse of nitrogen fertilisers in China is leading to rapid soil acidification and is causing lasting damage to ecosystems, according to soil study Nitrogen fertilisers used to increase crop yields in China are having “extreme” environmental consequences, according to a study from leading soil scientists.

The Global Wind Energy Council, a trade association based in Brussels, estimates that wind power capacity grew by 31 percent worldwide in 2009, with 37.5 additional gigawatts installed, bringing global wind power capacity to 157.9 gigawatts. China accounted for a third of the new capacity, and the Chinese market experienced more than 100 percent growth.…

A study by scientists from the U.S.’s National Climatic Data Center refutes claims from climate change skeptics that data from U.S. weather stations was seriously flawed and exaggerated the rate of temperature increases. The study, published in the Journal of Geophysical Research, says that U.S. weather stations may have actually slightly underestimated temperature increases. Anthony…

The Balkans are located in south east Europe. A new data set of high quality homogenized daily maximum and minimum summer air temperature series from 246 stations in the eastern Mediterranean region (including Albania, Bosnia-Herzegovina, Bulgaria, Croatia, Cyprus, Greece, Israel, Romania, Serbia, Slovenia, Turkey) has been developed and used to quantify changes in heat length…

NASA tracks asteroids all the time. They are difficult or impossible for the rest of us to ever glimpse. Now, the most prominent asteroid in the sky can be seen with binoculars — and perhaps even the naked eye, if you are in an area with reasonably dark skies at night. Tonight, Wednesday, Feb. 17,…

Yemeni water trader Mohammed al-Tawwa runs his diesel pumps day and night, but gets less and less from his well in Sanaa, which experts say could become the world’s first capital city to run dry. “My well is now 400 meters (1,300 feet) deep and I don’t think I can drill any deeper here,” said…

What makes an animal large or small? Part of it may be due to climate change. It may be that these are reactions to rapidly rising temperatures due to global climate change according to Professor Yoram Yom-Tov of Tel Aviv University, who has been measuring the evolving body sizes of birds and animals in areas…

Last year’s disappointing climate summit in Copenhagen demonstrated if not proved two important things about “saving the earth”: 1. Sustainability is a very emotional topic for some 2. Sustainability is a financial topic for most Unfortunately, what transpired in Copenhagen is probably the rule, rather than the exception. It was disheartening to realize the events…

Electric cars have many merits: They are quieter and require less maintenance than cars with internal combustion engines. A network of smartly located charging stations covering the entire Harz region in Germany is bound to make electric cars a regional feature. The Harz region is banking on electric cars. Electric cars will soon be rolling…
