Dinosaurs survived rapid climate change
(09/23/2006) New research suggests the existence of periods of dramatic climate change during the Mesozoic Era, a time when dinosaurs ruled the Earth. The research, published in the September issue of Geology, presents evidence that ocean surface temperatures varied as much as 6 degrees Celsius (about 11 degrees Fahrenheit) during the Aptian Epoch of the Cretaceous Period 120 million years ago according to scientists from Indiana University Bloomington and the Royal Netherlands Institute for Sea Research who examined ancient rocks from the bottom of the Pacific Ocean. The results challenge the idea that the period was characterized by a stable, hot and humid climate.

Amazon rainforest has its first wireless city under poverty alleviation initiative by Intel
(09/20/2006) Intel unveiled what it is calling the "World's Most Remote Digital City" in the heart of the Amazon rainforest. The wireless, high-speed Internet network installation in Parintins, a town on an island in the Amazon River, is part of the tech firm's initiative to treat the world's poor as a market. Some economists have argued that addressing the world's poor in such a manner could bring benefits that they have not seen through historical aid efforts.
Tree rings could settle global warming hurricane debate
(09/20/2006) Scientists have shown that ancient tree rings could help settle the debate as to whether hurricanes are strengthening in intensity due to global warming. By measuring different isotopes of oxygen present in the rings, Professors Claudia Mora and Henri Grissino-Mayer of the University of Tennessee have identified periods when hurricanes hit areas of the Southeastern United States up to 500 years ago. The research could help create a record of hurricanes that would help researchers understand hurricane frequency and intensity. Currently reliable history for hurricanes only dates back a generation or so. Prior to that, the official hurricane records kept by the National Oceanic and Atmospheric Administration's Atlantic basin hurricane database (HURDAT) are controversial at best since storm data from more than 20 years ago is not nearly as accurate as current hurricane data due to improvements in tracking technology. The lack of a credible baseline makes it nearly impossible to accurately compare storm frequency and strength over the period.
Extent of Mercury Pollution More Widespread, Report Shows
(09/20/2006) Mercury pollution is making its way into nearly every habitat in the U.S., exposing countless species of wildlife to potentially harmful levels of mercury, a new report from the National Wildlife Federation shows.
Arctic ice hole larger than Britain forms, shocks scientists
(09/20/2006) European Space Agency satellite images acquired from 23 to 25 August 2006 have shown for the first time dramatic openings larger than the size of the British Isles in the Arctic's perennial sea ice pack north of Svalbard, and extending into the Russian Arctic all the way to the North Pole. The agency says the findings are shocking to scientists. 'If this anomaly trend continues, the North-East Passage or 'Northern Sea Route' between Europe and Asia will be open over longer intervals of time, and it is conceivable we might see attempts at sailing around the world directly across the summer Arctic Ocean within the next 10-20 years,' said Mark Drinkwater, a scientist with ESA.

(09/19/2006) Unless you're a space buff, you probably missed the latest news from Mars. The Rover mission has now determined that a promontory scientists call "McCool Hill" is 85 feet taller than nearby "Husband Hill." Stop the presses! Exploring new frontiers in the quest for knowledge has inspired humans for centuries, and today's extraterrestrial search for alien life forms and clues to our origin, captures the public's imagination like few others.
China makes environmental moves as problems mount
(09/19/2006) China, the world's most populous country and fastest growing economy, faces a host of environmental problems. Energy and water shortages, water and air pollution, cropland and biodiversity losses, and escalating emissions of greenhouses gases are all concerns as the country moves towards world superpower status. While these issues could threaten to destablilize the country and derail economic growth, it appears that it is taking steps to address some of these challenges.
Expansion of agriculture in the Amazon may impact climate
(09/19/2006) A new study from NASA scientists shows that forest clearing for large-scale agriculture has recently become a significant cause of deforestation in the Brazilian Amazon. The researchers warn that this change in land use may affect the region' climate and the Amazon's ability to absorb carbon dioxide, a potent greenhouse gas.
War-torn Congo Announces Two New Parks
(09/18/2006) The Minister of forestry Economy of the Republic of Congo announced today plans to create two new protected areas that together could be larger than Yellowstone National Park, spanning nearly one million hectares (3,800 square miles). Instead of bison and elk, these new protected areas contain elephants, chimpanzees, hippos, crocodiles, and some of the highest densities of gorillas on earth. The announcement was made by Minister Henri Djombo and officials from the Bronx Zoo-based Wildlife conservation Society (WCS) at the United Nations.
Climate Change Threatens Lemurs
(09/18/2006) Tropical rainforests are among the most stable environments on Earth, but they are still no match for global climate change. Dr. Patricia Wright, the widely admired primatologist and Professor of Anthropology at Stony Brook University, finds that climate change could mean the difference between survival and extinction for endangered lemurs.
New species of 'walking' shark discovered
(09/18/2006) Two recent expeditions led by conservation International (CI) to the heart of Asia'Coral Triangle' discovered dozens of new species of marine life including epaulette sharks, 'flasher' wrasse and reef-building coral, confirming the region as the Earthapos;s richest seascape.
Shift from hard drives to flash may have environmental benefits
(08/29/2006) A leading technology research group says flash, or solid state memory drives may soon replace the standard hard drives in laptops. Over the past few years, flash memory technology has been claiming an increasingly sizeable share of the market, particularly in the form of USB drives. According to the Gartner Group, the NAND flash market has grown from 1.56 billion in 200 to 11.42 billion in 2005, with even higher projections for the next two years. This summer, Samsung set a new bar by releasing computers that utilize flash memory storage, negating the need for traditional magnetic disk media. The implications of a shift for laptops are significant for a number of reasons including changing performance demand, market trends and investment opportunities. Unconsidered at this point, but nonetheless compelling, is the possible environmental impact of such a transition.
Acid rain affects one-third of China
(08/28/2006) One-third of China is impacted by acid rain according to officials quotes Sunday by state media. The Associated Press reports that China's factories are sending ever increasing amounts of sulphur dioxide -- the chemical that causes acid rain -- according to Sheng Huaren, deputy chairman of the Standing Committee of parliament. Emissions of sulphur dioxide have risen by 27 percent since 2000.
One year later: Hurricane Katrina in review
(08/28/2006) While hurricane Katrina was the most devastating, causing 1833 fatalities and over $81 billion in damage, it was not the strongest storm of the year -- both Hurricane Rita and Hurricane Wilma were more powerful. Katrina, which at one point in the Gulf of Mexico was a Category 5 hurricane, was only a Category 3 hurricane when it made landfall near New Orleans on August 29, 2005. Nevertheless, the damage was extensive.
Remote island provides clues on population growth, environmental degradation
(08/25/2006) Halfway between South America and New Zealand, in the remote South Pacific, is Rapa. This horseshoe-shaped, 13.5 square-mile island of volcanic origin, located essentially in the middle of nowhere, is 'a microcosm of the world's situation,' says a University of Oregon archaeologist.
Climate change causing early spring
(08/25/2006) Spring is arriving earlier across Europe than it did 30 years ago according to new research published in the journal Global Change Biology. Scientists from 17 nations examined 125,000 studies involving 561 species and found that spring is beginning on average six to eight days earlier than it did 30 years ago. The researchers said that in countries where rapid increases in temperature have occurred, that figure is almost doubled.

(08/25/2006) Climate change 14 million years ago produced catastrophic drainage of subglacial lakes in Antarctica causing dramatic changes in the continent's landscape according to new research.
Why some Himalayan glacies aren't melting due to climate change
(08/25/2006) New research into climate change in the Western Himalaya and the surrounding Karakoram and Hindu Kush mountains could explain why many glaciers there are growing and not melting. The findings suggest this area, known as the Upper Indus Basin, could be reacting differently to global warming, the phenomenon blamed for causing glaciers in the Eastern Himalaya, Nepal and India, to melt and shrink.
Recovery of biodiversity after dinosaurs was chaotic
(08/24/2006) The recovery of biodiversity after the end-Cretaceous mass extinction was much more chaotic than previously thought, according to paleontologists. New fossil evidence shows that at certain times and places, plant and insect diversity were severely out of balance, not linked as they are today. The extinction took place 65.5 million years ago. Labeled the K-T extinction, it marks the beginning of the Cenozoic Era and the Paleocene Epoch.
North Atlantic Ocean freshening could weaken Gulf Stream
(08/24/2006) A new analysis of 50 years of changes in freshwater inputs to the Arctic Ocean and North Atlantic may help shed light on what's behind the recently observed freshening of the North Atlantic Ocean. In a report, published in the August 25, 2006 issue of the journal, Science, MBL (Marine Biological Laboratory) senior scientist Bruce J. Peterson and his colleagues describe a first-of-its-kind effort to create a big-picture view of hydrologic trends in the Arctic. Their analysis reveals that freshwater increases from Arctic Ocean sources appear to be highly linked to a fresher North Atlantic.
Genetically modified tree could be used for cellulosic ethanol biofuel
(08/24/2006) A tree that can reach 90 feet in six years and be grown as a row crop on fallow farmland could represent a major replacement for fossil fuels. Purdue University researchers are using genetic tools in an effort to design trees that readily and inexpensively can yield the substances needed to produce alternative transportation fuel.
Feathers, human hair used to fight oil spill in Philippines
(08/24/2006) The Philippines has asked for hair clippings from salons and chicken feathers to help fight the country's worst oil spill, according to a report from Reuters. The oil spill occurred August 1 after Solar I, an oil tanker chartered by Petron Corp. sank in rough seas. About 1700 barrels spilled initially, but because the tanker sank in deep water with as much as 15,300 barrels of bunker oil, more is expected to leak into the surrounding environment. According to Greenpeace, about 320 kilometers of coastline -- including a coral reef located in a marine reserve and 27 coastal villages -- have been affected by the spill.
Tropical rain forest insects have diet similar to temperate insects
(08/24/2006) A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected - that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects.
Viruses can jump primate-human species barrier, researchers warn
(08/23/2006) Viruses that jump the species barrier between monkeys and humans can harm both people and animals, and we should take steps to reduce the risk of virus transmission. That's the message running through the September issue of the American Journal of Primatology, a special issue on disease risk analysis edited by a primate expert at the University of Washington.
Americans believe hot weather, hurricanes linked to global warming
(08/23/2006) As first anniversary of Hurricane Katrina nears, a just-released Zogby poll shows that not only are Americans more convinced global warming is happening, they are also linking recent intense weather events like Hurricane Katrina and this summer's heat wave and droughts to global warming.
Gecko feet inspire high-friction micro-fibers
(08/22/2006) Inspired by the remarkable hairs that allow geckos to hang single-toed from sheer walls and scamper along ceilings, a team of researchers led by engineers at the University of California, Berkeley, has created an array of synthetic micro-fibers that uses very high friction to support loads on smooth surfaces.
1 in 3 U.S. National Parks Polluted

Ancient blue whale was a shark killer
(08/22/2006) A 25-million-year-old whale fossil from southeastern Australia suggests a curious origin for baleen whales. Presented at the at the Melbourne Museum last week, the fossil shows that earliest baleen whales were small, toothed and highly predatory creatures with enormous eyes -- virtually the opposite of the baleen whales we know today. These, like the blue whale and the humpback are gentle, toothless giants that feed on krill and other tiny organism.
New potential fuel source carries global warming risk
(08/22/2006) Scientists supported by the Integrated Ocean Drilling Program, an international marine research program that explores sea floor sediments and rocks, announced that they found deposits of methane gas hydrates at considerably less depth than expected. The discovery, published in the August. 15, 2006 edition of EOS may have implications for future energy use as well as climate change.
Hobbits don't exist; ancient human skeleton not a pygmy
(08/21/2006) The skeletal remains found in a cave on the island of Flores, Indonesia, reported in 2004, do not represent a new species as then claimed, but some of the ancestors of modern human pygmies who live on the island today, according to an international scientific team.
Forest fires causing mercury pollution in North America
(08/21/2006) Increasing numbers of wildfires due to climate change could worsen mercury pollution in North America according to a new study from researchers at Michigan State University, the U.S. Geological Survey, the National Center for Atmospheric Research, and the Canadian Forest Service. Wildfires are releasing mercury long ago sequesterd in Northern wetlands.
Global water problem: one in three face water scarcity
(08/21/2006) One in three people is enduring one form or another of water scarcity, according to a new report from the International Water Management Institute (IWMI). The assessment, carried out by 700 experts from around the world over the last five years, was released at World Water Week in Stockholm, a conference exploring the management of global water resources.
