conservation news and environmental science news.Unchecked global warming will cost trillions says report (10/14/2006) A new Friends of the Earth-backed report by economists at Tufts University's Global Development and Environment Institute says that global warming could cost trillions of dollars should temperature increases exceed two degrees centigrade (3.6 degrees Fahrenheit) Phytoplankton generate about five times as much energy as humans finds study (10/14/2006) A new study estimates that oceanic phytoplankton generate about five times the annual total energy consumption of humans. NAND PCs may have environmental benefits over standard hard disk PCs
(10/13/2006) Fujitsu announced it will start shipping PCs that use NAND-flash drives instead of standard hard drives. While the new format will be substantially more expensive -- on the order of $670 to replace a 20GB hard drive with a 16GB worth of flash memory -- it will make the laptops lighter and more shock-resistant, extend battery life by 30 minutes and improve system performance on start-up. The shift may have ancillary benefits as well: less energy usage and reduction of components that use metals. The following originally appeared on October 28, 2006 on mongabay.com.
Shell estimates cost of fighting climate change at 0.3% GDP (10/13/2006) A new report by Shell Oil estimates that the cost of fighting climate change in the Britain by 2010 would be equivalent to just 0.3 percent of GDP. The report also says that the effort to address climate change could be worth £30bn ($56 billion) to businesses in the UK. Insurance industry needs to do more to fight global warming (10/13/2006) The insurance industry needs to do more to address the growing impact of climate-change induced damaged according to a report issued this week by insurance giant Allianz and environmental group WWF. Methane from peat bogs may worsen global warming (10/13/2006) New research says that methane released from peat bogs at the end of the past ice age worsen global warming. The study warns that a similar event could worsen climate change by causing a rapid shift in atmospheric greenhouse gas concentrations. Solar Energy Powers Mainland China's Richest Man (10/12/2006) The largest private fortune in mainland China may belong to Shi Zhengrong, the founder of the China's largest producer of photovoltaic equipment used to convert sunlight into eletricity, according to an article in today's edition of The Wall Street Journal. Warming climate causing Alaska lakes to dry up (10/12/2006) More than 10,000 Alaskan lakes "shrunk in size or completely dried up" between 1950 and 2002 according to a study published in the Journal of Geophysical Research--Biogeosciences. The study says that during this period, "Alaska has experienced a warming climate with longer growing seasons, increased thawing of permafrost, and greater water loss due to evaporation from open water and transpiration from vegetation; yet there has been no substantial change in precipitation." Extinction may be linked to Earth's tilt and orbital variations (10/12/2006) A new study suggests that variations in Earth's orbit and tilt may be linked to extinctions of mammal species. Examining the fossilized teeth of rodents over a 22 million year period, researchers lead by Jan van Dam of Utrecht University in the Netherlands found that the disappearance of mammal species -- which survive an average of 2.5 million years before going exinct -- cluster around specific cycles at one million and 2.4 million years. The one million year cycle correponds to wobbles in Earth's orbit, while the 970,000-year cycle is tied to shifts of the Earth on its axis. The cycles are assocation with lower temperatures and changes in precipitation. Bering Strait land bridge may have flooded earlier than thought (10/11/2006) Researchers have found evidence suggesting that the Bering Strait land bridge believed to be the major route for human migration from Asia to the Americas may have flooded about 1,000 years earlier than widely thought. The findings may help scientists develop ocean and climate histories for the region to better understand human migration. The study is published in the October issue of Geology magazine by researchers at the Woods Hole Oceanographic Institution, the Scripps Institution of Oceanography, and the University of Massachusetts, Amherst. Global warming and pollution could doom oysters (10/11/2006) Oysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, according to a new study presented at The American Physiological Society conference, Comparative Physiology 2006. Higher oxygen levels could produce monster insects (10/11/2006) Higher concentrations of oxygen could produce giant insects according to a paper presented at the Comparative Physiology conference currently meeting in Virginia Beach, Virginia. The paper, 'No giants today: tracheal oxygen supply to the legs limits beetle size,' based on research by a team of American researchers, offers evidence that Paleozoic insects were substantially larger because they had a richer oxygen supply. During the late Paleozoic period, about 300 million years ago, the air's oxygen content was around 35 percent, compared to 21 percent today. As a result some dragonflies had two-and-a-half-foot wing spans, while giant spiders roamed the ancient forests. Photo of new bird species discovered in Colombia (10/10/2006) A bird species new to science has been discovered on a remote mountain range in northern Colombia according to conservation International.

Pearson, a research professor at the School of Life Sciences at Arizona State University (ASU) in Tempe, Arizona, focuses on a different approach: education.
Massive coral bleaching in Madagascar (10/06/2006) A new survey of reefs along Madagascar's southwestern coast found massive damage from coral bleaching, including some reefs that lost up to 99 percent of their coral cover. But the survey team, led by the conservation groups Blue Ventures and the Wildlife conservation Society (WCS) and funded by conservation International (CI), also found some signs of hope. Scientists discovered several small reefs with corals that appeared to be resilient to rising sea temperatures and could ultimately be used to reseed damaged reefs. These resilient reefs may also provide valuable information about how to protect corals from future damage. Global warming threatens western U.S. (10/06/2006) Global warming will cause drastic changes -- including reduction in snowpack, worsening droughts, increases in wildfire and invasive species, and loss of regional biodiversity -- in the American West if greenhouse gas emissions are not curtailed according to a new report from the National Wildlife Federation.

The results of the research have been published in the Proceedings of the National Academy of Sciences of The United States of America. Poison frogs less toxic when habitat degraded (10/02/2006) A new study suggests habitat degradation may put some frogs at greater risk of predation by reducing their toxicity. Studying Mantella poison frogs on the island of Madagascar, a team of researchers led by Valerie C. Clark, a chemistry PhD student at Cornell University who earlier this year published a paper describing the origin of frog toxins as being the insects upon which they feed, found that frogs collected from intact forests "consistently have a greater diversity of insect-derived toxins accumulated in their skin than do frogs from disturbed and fragmented forests." Ozone loss hits record in 2006 (10/02/2006) The European Space Agency (ESA) said that ozone loss in Antarctica hit a record in 2006. ESA reports that ozone measurements made by the Envisat satellite showed the ozone loss of 40 million tons of ozone, a level exceeding the previous record ozone loss of about 39 million tonnes for 2000.
