Study: Global Warming Effecting North America's Northernmost Arctic Lake
September 29, 2007 05:35 PM - Paul Schaefer, ENN
Quebec, Canada - Analyses conducted by researchers from Université Laval’s Center for Northern Studies reveal that aquatic life in Ward Hunt Lake, the continent’s northernmost lake, is affected by climate change.
Ward Hunt Lake is a body of water located on a small island north of Ellesmere Island in the Canadian Arctic, has undergone major transformations within the last two centuries. The speed and range of these transformations—unprecedented in the lake’s last 8,000 years—suggest that climate change related to human activity could be at the source of this phenomenon.
The researchers’ conclusions are based on the analysis of a sediment core extracted in the center of Ward Hunt Lake in August 2003. This 18 centimeter long sediment core containing algae pigments and diatom remnants was used by the researchers as a biological archive in order to determine the diversity and abundance of aquatic life-forms in the lake over the last 8,450 years.
Researchers Discover Tropical Kelp Forests

Santa Barbara, California - Santa Barbara, California - Researchers have discovered large undersea forests of endangered kelp in areas previously thought to be bare of the plant, in the tropics. Using a computer model, researchers believe they've located nearly 10,000 square miles of areas that could harbor the plant. "The ecosystems that form in these cold, deep pockets beneath warm tropical waters look more like their cousins in California than the tropical reefs just 200 feet above," said co-author Brian Kinlan, a researcher with UC Santa Barbara's Marine Science Institute. "It is very similar to what we see when we climb a high mountain. For example, high alpine country in California looks more like Alaska."
Tropical Storm Melissa Whirls In Atlantic
September 29, 2007 03:35 PM -
MIAMI (Reuters) - Tropical Storm Melissa formed in the Atlantic Ocean on Saturday but posed no immediate threat to land, while Tropical Depression Karen weakened, the National Hurricane Center said.
As of 11 a.m. EDT, Melissa was about 300 miles
west of the Cape Verde Islands, moving northwest at eight miles per hour (13 kilometers per hour) with winds of 40 mph, the hurricane center said.
"Little change in strength is forecast during the next 24 hours," the center's advisory said.
Solar Parking Lot Will Deliver 1-Megawatt To Santa Rosa, California
September 28, 2007 07:20 PM -
SAN JOSE and SANTA CLARA, Calif., - SunPower Corporation, a manufacturer of high-efficiency solar cells, solar panels and solar systems, and Agilent Technologies today announced they'll install a 1-megawatt solar tracking system at Agilent's Santa Rosa, Calif., campus on top of a canopy structure in the campus parking lot, providing both shade in the lot and solar electric power for the facility. A lot of power.
The SunPower Tracker, which follows the sun's movement throughout the day. Using SunPower solar panels, the highest efficiency panels on the market today, the system is expected to generate an estimated 1.8 million kilowatt-hours per year, offsetting more than 33 million pounds of carbon dioxide over the next 30 years. This is equivalent to planting more than 4,700 acres of trees or removing 3,300 cars from California's roadways.
Karen may turn toward U.S. East Coast, depression forms
September 28, 2007 05:35 PM -
NEW YORK (Reuters) - Even as Tropical Storm Karen weakened over the central Atlantic on Friday, weather models showed the storm could turn westward toward Puerto Rico or the East Coast of North America over the next five days.
Elsewhere in the Atlantic, the U.S. National Hurricane Center said Tropical Depression 14 formed about 210 miles southwest of the Cape Verde Islands.
Karen, meanwhile, was about 805 miles east-northeast of the Windward Islands of Dominica, Martinique, Saint Lucia, Saint Vincent, the Grenadines and Grenada at about 11 a.m. EDT, the NHC said in a report.
It was too soon to say where, if at all, either storm would make landfall.
3 Dead, Hurricane Lorenzo Plows Into Mexico

NAUTLA, Mexico (Reuters) - Hurricane Lorenzo crashed into Mexico's Gulf coast on Friday, killing three people in a mudslide and knocking out power to 85,000 homes.
In the coastal fishing town of Nautla, Lorenzo's 80 mph (130 kph) winds ripped off bits of roofs, blew down trees and scattered debris in the streets.
"It hit us hard and there is an incredible amount of rain," said Mayra Castro, 29, a waitress who spent the night mopping up water that leaked into her house through windows and under doors.
UK Power Giants Fail to Show Leadership on Climate Change
September 28, 2007 09:33 AM - WWF
The UK's biggest power companies are failing to show leadership on climate change and to adopt cleaner business models to deliver a sustainable low-carbon UK economy, according to two new reports commissioned by WWF-UK. The reports compare the climate change targets and policies of the six biggest power companies.RWE npower and EDF Energy performed poorly in both reports, showing the least progress in addressing climate change issues.
Climate Change Bill Calls for 50-cent Fuel Tax
September 28, 2007 09:13 AM - Reuters
WASHINGTON - U.S. drivers would pay a 50-cent tax on each gallon of gasoline they pump to encourage less fuel use and cut greenhouse gas emissions, under draft legislation to fight global warming released on Thursday. "In order or reduce greenhouse gas emissions and make the planet safe and healthy for future generations it will take a significant investment from all of us," said Rep. John Dingell, the powerful chairman of the House Energy and Commerce Committee. "A fee on carbon emissions requires a tithe from all citizens and industries, but no one entity will be unfairly leveled with a devastating burden," Dingell said about his climate change proposal.
Arctic Thaw May be at "Tipping Point"
September 28, 2007 08:57 AM - Reuters
OSLO- A record melt of Arctic summer sea ice this month may be a sign that global warming is reaching a critical trigger point that could accelerate the northern thaw, some scientists say. "The reason so much (of the Arctic ice) went suddenly is that it is hitting a tipping point that we have been warning about for the past few years," James Hansen, director of NASA's Goddard Institute for Space Studies, told Reuters. The Arctic summer sea ice shrank by more than 20 percent below the previous 2005 record low in mid-September to 4.13 million sq km (1.6 million sq miles), according to a 30-year satellite record. It has now frozen out to 4.2 million sq km.
Tropical Storm Lorenzo Lashes Mexico's Gulf Coast
September 28, 2007 08:39 AM - Reuters
MEXICO CITY (Reuters) - Lorenzo was downgraded to a tropical storm over Mexico on Friday hours after it swept ashore as a Category 1 hurricane, dumping heavy rain on the already waterlogged state of Veracruz. Lorenzo lost force after it made landfall near the Gulf of Mexico port city of Tuxpan, and its maximum wind speed had dropped to 65 mph (100 kph) by 5 a.m. EDT (0900 GMT), the U.S. National Hurricane Center said. The storm was not seen affecting Mexico's oil production but around 100,000 people living between Tuxpan and the town of Nautla further south were evacuated to storm shelters.
