Oct. 29, 2008 -- Paleontologists are sifting through the soil of an excavated lot in search of ancient plants, the only ones from the early Jurassic period found so far in western North America.
The flora fossils date back 198 million years, Utah's state paleontologist Jim Kirkland said Tuesday. "Every plant they've identified has been new," he said.

Tropical Cyclones Wash Away Carbon
Oct. 21, 2008 -- Hurricanes and typhoons, normally seen as looming threats from global warming, are actually helping to remove carbon dioxide from the atmosphere.
Each year humans emit approximately 7.2 billion tons of the greenhouse gas, trapping vast amounts of heat in the air and oceans. Tropical cyclones derive their energy from warm seas, and some scientists believe global warming will spawn more frequent and more intense storms unless drastic effort is undertaken to cut emissions.

Rock Shows Earth Got Off to Hot Start
Oct. 20, 2008 -- A geological controversy over how a 2,700-million-year-old rock was formed has been solved using synchrotron technology, an international team reports.
A rare form of magmatic rock known as komatiite was formed in the Earth's mantle at temperatures around 1700 degrees Celcius in the Archaean age, more than 2,700 million years ago, according to report in the latest Nature journal.
Australian co-author Leonid Danyushevsky, at the Australian Research Council Center of Excellence in Ore Deposits at the University of Tasmania, said the finding settles a long-disputed controversy over the volcanic rock's origin.

Ozone Pollution to Worsen Under Climate Change
Surface-level ozone, a poisonous gas that claims tens of thousands of lives annually, could get much worse thanks to the effects of climate change, according to new research.
While international treaties like the Kyoto Protocol attempt to curb greenhouse gas emissions and limit the effects of global warming, researchers say ozone is a silent killer that has stayed below the radar.
"It's the third most important greenhouse gas after carbon dioxide and methane," David Fowler of the National Environmental Research Council in the United Kingdom said. "But it's not the biggest one, and it's not the biggest threat to human health -- particulates in the atmosphere are worse. So it's a sort of Cinderella gas that has been mostly ignored."

Crumbling Glacier Quakes as It Breaks
On the west coast of Greenland, a glacier's crumbling edge is producing seismic groans.
As the Arctic warms, scientists are keeping a close eye the Jakobshavn glacier. Already one of the world's fastest moving ice streams, over the last decade scientists watched alarmed as it sped up further, sometimes sliding dozens of feet per day toward the Ilulissat Fjord.

'Dramatic evidence' of Arctic melt, experts warn
Federal report cites signals from Greenland ice sheet to reindeer herds
WASHINGTON - Autumn temperatures in the Arctic are at record highs, the Arctic Ocean is getting warmer and less salty as sea ice melts, and reindeer herds appear to be declining, researchers reported Thursday.
"Obviously, the planet is interconnected, so what happens in the Arctic does matter" to the rest of the world, Jackie Richter-Menge of the Cold Regions Research and Engineering Laboratory in Hanover, N.H., said in releasing the third annual Arctic Report Card for the federal National Oceanic and Atmospheric Administration.
"There continues to be widespread and, in some cases, dramatic evidence of an overall warming of the Arctic system," the experts stated in their report.

Whale autopsy: Trash clogged its intestine
Plastic bag, rope and bottle cap appear to have killed 3-ton female
KUALA LUMPUR, Malaysia - A beached whale has died in Malaysia after swallowing a plastic bag, a rope and a bottle cap, a marine researcher said Wednesday.
The 30-foot-long Bryde's whale got stranded in eastern Pahang state Monday and died a day later despite villagers' efforts to save it, said Mohamad Lazim Mohamad Saif, a researcher with the Turtle and Marine Ecosystem Center, who was at the scene.
Mohamad Lazim said the preliminary findings of an autopsy showed the female had swallowed a black plastic bag, a rope and a bottle cap, which clogged its intestine.

Doubt, anger over dams on Amazon tributary
Many in Brazil question human, environmental costs of projects
PORTO VELHO, Brazil - It is quiet here on the wrong side of progress. Hot wind blows dust across the dry bluffs. The brown river runs wide and placid.
In his painted wooden skiff, Francisco Evangelista de Abreu, a fisherman, motors up-current. Two river dolphins crest and submerge. His mind is elsewhere. The dam is coming.
"I don't know what's going to happen," he said. "I don't have any experience outside of this."

Economic woes could curtail action on warming
Focus shifts from capping greenhouse gases to stabilizing economy
WASHINGTON - The economic free fall gripping the nation may bring down one of the main environmental objectives: capping the greenhouse gases that are blamed for global warming.
Democratic leaders in the House and the Senate, and both presidential candidates, continue to rank tackling global warming as a chief goal next year. But the focus on stabilizing the economy probably will make it more difficult to pass a law to reduce carbon dioxide and other greenhouse gases. At the very least, it will push back when the reductions would have to start.
As one Republican senator put it, the green bubble has burst.

Canada government faces suit over killer whales
Activists want the Pacific Coast mammal protected by law
VANCOUVER, British Columbia - Environmentalists are taking the Canadian government to court, demanding it use the country's Species at Risk Act to protect killer whales off British Columbia.
Ecojustice, on behalf of eight environmental organizations, filed notice Wednesday in Federal Court of a lawsuit to force officials to use the legislation to safeguard the habitat of southern and northern resident killer whales, listed as endangered and threatened, respectively.
The move is in reaction to a notice posted by the Department of Fisheries and Oceans on the Species at Risk Act registry last month contending that orcas, commonly known as killer whales, are already protected by other laws, regulations and guidelines.

Arctic stormier as Earth warms, study finds
Pace of sea ice also quickens, which could help climate by churning ocean
The Arctic has become more stormy in the past 50 years due to the warming climate, which in turn has quickened the pace of drifting sea ice, a new NASA study finds.
Based on model results, climate scientists had long predicted that a warming climate would increase the frequency and intensity of Arctic storms as ocean waters became progressively warmer.
Now, a team of climate scientists has analyzed 56 years on data of the paths that storms took, as well as annual data on general storm activity, which confirmed an accelerating trend in Arctic storm activity 1950 to 2006.

N.J. vows to 'race to the sea' for wind power
Governor leads cause; $1 billion offshore plan may power 125,000 homes
ATLANTIC CITY, N.J. - New Jersey is powering up an ambitious plan to become a world leader in the use of wind-generated energy.
Gov. Jon Corzine wants the Garden State to triple the amount of wind power it plans to use by 2020 to 3,000 megawatts. That would be 13 percent of New Jersey's total energy, enough to power between 800,000 to just under 1 million homes.
"We want to create this generation's race to the moon, but this time, a race to the sea, to harness this potential wind source off of our coasts, and bring economic development, environmental benefits, and new, green jobs to the Garden State," Corzine said Monday.

'Chemical Equator' Keeps Polluted Air in the North
Sept. 26, 2008 -- Wrapping around Earth's equator like a belt, a boundary of air is keeping the polluted atmosphere of the Northern Hemisphere separate from the relatively pristine south.
A team of researchers led by Jacqueline Hamilton of York University in the United Kingdom have dubbed the peculiar wall of air the "chemical equator." And while scientists have known about the feature for decades, Hamilton's team has just discovered an odd new wrinkle in its behavior.

Curb sprawl to help climate? California will try
New law encourages cities to locate homes near job centers
SACRAMENTO, Calif. - Gov. Arnold Schwarzenegger signed legislation Tuesday that attempts to ease greenhouse gas emissions by giving priority to transportation projects that limit commutes and curb urban sprawl.
Supporters said the legislation is needed to help implement a 2006 law that requires California to reduce its greenhouse gas emissions to 1990 levels by 2020.
The bill requires the state Air Resources Board to set regional targets for reducing greenhouse gas emissions from cars and light trucks and directs regional planning agencies to develop land-use strategies to meet those targets.
