Groups Seek Reinstatement of Protections for Sierra Bellwether Species

Bighorn sheep, California condor, and Northern goshawk habitat all threatened

San Francisco, CA — A coalition of conservation groups is taking the Bush administration to court because of weak management plans that threaten wildlife in 10 Sierra Nevada national forests.

The groups are striving to restore safeguards for a variety of Sierra wildlife, including bighorn sheep, the endangered California condor, and the Northern goshawk, following the removal of their protections by the Bush administration.

In December 2007, the Bush administration removed specific monitoring requirements for indicator species, plants and animals that must be studied before the U.S. Forest Service can approve logging, road building and other forest-related projects that could destroy sensitive habitat for threatened or endangered species.

“The Bush administration eliminated an important safety net for Sierra forests and wildlife,” said Craig Thomas of Sierra Forest Legacy. “We want the court to reinstate these vital protections that have been a critical component of forest management plans for decades.”

Indicator species are studied because their well-being reflects the overall health of a forest. If the Forest Service finds that logging, road building and other forest projects could harm these bellwether species, it must take action to ensure that such species and their habitat are protected before revving up the chainsaws or bulldozing new roads into the forest.

Under the new provisions, the Forest Service is only required to collect monitoring data for a fraction of the species previously covered by the plans. The Forest Service cut the number of management indicator species from approximately 60 to just 13.

“By eliminating these common sense monitoring requirements for imperiled species, the Bush Administration continues its assault on our national forests,” said Marc Fink, attorney with the Center for Biological Diversity. “We are hopeful the courts will once again find that the Forest Service has violated the law through its weakening of long-standing environmental protections.”

“The National Environmental Policy Act and the Endangered Species Act require the public to be informed of projects that may have significant impacts on Sierra Nevada wildlife and their habitats,” said Erin Tobin of Earthjustice. “Federal agencies are supposed to look before they leap, not dismiss the tools needed to protect species on the brink of extinction.”

Forest management plans govern most activities that occur in our national forests. Provisions to monitor the health of important wildlife and its forest habitat are the cornerstone of such plans because the monitoring information improves forest planning and decision making that otherwise could jeopardize species and habitat. Forest plans managing that habitat must comply with the National Forest Management Act and the Endangered Species Act, which require the Forest Service to protect the diversity of fish and wildlife in our national forests.

The Forest Service adopted forest plans for the 10 national forests in the Sierra Nevada in the 1980s and early 1990s. These forest plans established clear forest-wide monitoring requirements for certain management indicator species to ensure well-distributed and healthy populations of all plant and animal communities within each forest and throughout the entire Sierra Nevada. Additionally, in 2001, the Forest Service adopted a comprehensive Sierra-wide monitoring plan to improve its ability to protect these and other at-risk species.

Global Warming: Warmer Seas Linked To Strengthening Hurricanes, According to New Research

ScienceDaily (Sep. 4, 2008) — The theory that global warming may be contributing to stronger hurricanes in the Atlantic over the past 30 years is bolstered by a new study led by a Florida State University researcher. The study will be published in the Sept. 4 edition of the journal Nature.

Using global satellite data, FSU geography Professor James B. Elsner, University of Wisconsin-Madison Professor James P. Kossin and FSU postdoctoral researcher Thomas H. Jagger found that the strongest tropical cyclones are, in fact, getting stronger — and that ocean temperatures play a role in driving this trend. This is consistent with the “heat-engine” theory of cyclone intensity.

“As seas warm, the ocean has more energy that can be converted to tropical cyclone wind,” Elsner said. “Our results do not prove the heat-engine theory. We just show that the data are quite consistent with it.”

Kerry Emanuel of the Massachusetts Institute of Technology first suggested the possible connection between global warming and increases in tropical cyclone intensity in a 2005 paper. He linked the increased intensity of storms to the heating of the oceans, which has been attributed to global warming.  Keep Reading

Role Of Aerosols In Climate Change Examined

ScienceDaily (Sep. 8, 2008) — A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models. Their work appears in the 5 September issue of Science magazine.

The increase in atmospheric concentrations of man-made aerosols—tiny particles suspended in the air—from such sources as transportation, industry, agriculture, and urban land use not only poses serious problems to human health, but also has an effect on weather and climate.

Recent studies suggest that increased aerosol loading may have changed the energy balance in the atmosphere and at the Earth’s surface, and altered the global water cycle in ways that make the climate system more prone to precipitation extremes.

It appears that aerosol effects on clouds can induce large changes in precipitation patterns, which in turn may change not only regional water resources, but also may change the regional and global circulation systems that constitute the Earth’s climate. Keep reading

Bad Sign For Global Warming: Thawing Permafrost Holds Vast Carbon Pool

ScienceDaily (Sep. 7, 2008) — Permafrost blanketing the northern hemisphere contains more than twice the amount of carbon in the atmosphere, making it a potentially mammoth contributor to global climate change depending on how quickly it thaws.

So concludes a group of nearly two dozen scientists in a paper appearing this week in the journal Bioscience. The lead author is Ted Schuur, an associate professor of ecology at the University of Florida.

Previous studies by Schuur and his colleagues elsewhere have estimated the carbon contained in permafrost in northeast Siberia. The new research expands that estimate to the rest of the permafrost-covered northern latitudes of Russia, Europe, Greenland and North America. The estimated 1,672 billion metric tons of carbon locked up in the permafrost is more than double the 780 billion tons in the atmosphere today.

“It’s bigger than we thought,” Schuur said.

Permafrost is frozen ground that contains roots and other soil organic matter that decompose extremely slowly. When it thaws, bacteria and fungi break down carbon contained in this organic matter much more quickly, releasing it to the atmosphere as carbon dioxide or methane, both greenhouse gases.

Glaciers In The Pyrenees Will Disappear In Less Than 50 Years, Study Finds

ScienceDaily (Sep. 6, 2008) — Much has been said about the situation of the glaciers in Greenland and Antarctica, but little is known about those in the high mountain areas of the Iberian Peninsular. A Spanish research study has revealed, for the first time, that now only the Pyrenees has active glaciers.

Furthermore, the steady increase in temperature, a total of 0.9°C since 1890, indicates that Pyrenean glaciers will disappear before 2050, according to experts.

Researchers from the University of Cantabria, the Autonomous University of Madrid and Valladolid have produced a summary on the current situation of the Pyrenees, Sierra Nevada and Picos de Europa. Scientists have based their work on how climate change has affected the glaciers since the so-called Little Ice Age (from 1300 to 1860) to conclude that only the Pyrenees has active glaciers left.

“High mountains are particularly sensitive areas to climate and environmental changes, and how glaciers evolve there in response to climate change is one of the most effective indicators of current global warming, in this case evidenced in Iberian mountain ranges”, explained the main study researcher and professor from the University of Cantabria, Juan José González Trueba, to SINC.  Keep Reading

Richmond CA City Council Sued Over Approval of Chevron Refinery Expansion

Expansion endangers public health and environment

September 4, 2008

Richmond, CA — Environmental justice groups, represented by lawyers from Earthjustice and Communities for a Better Environment, filed a lawsuit today challenging the Richmond City Council’s approval of Chevron’s refinery expansion project.

At issue is an environmental review that concealed that the project would result in much higher levels of air pollution and increased risks of catastrophic accidents and oil spills. Communities in Richmond, particularly low-income and communities of color, are severely overburdened with industrial pollution-related health problems, including high rates of asthma and cancer. Chevron’s refinery is the largest industrial polluter in the region.

Biological Invasions Increasing Due To Freshwater Impoundments, Says Study

ScienceDaily (Sep. 3, 2008) — The growing number of dams and other impoundments is increasing the number of invasive species and the speed at which they spread, putting natural lakes at risk, says a study led by the University of Colorado at Boulder.

The research team combined data on water chemistry, the distribution of five “nuisance invaders” and boating activity from the Great Lakes region. The results showed the increasing occurrence of such species in impoundments creates “stepping-stone habitats” for them into natural lakes, ponds and waterways in the region, said CU-Boulder Assistant Professor Pieter Johnson, co-lead author of the study.

The researchers looked at invaders like the Eurasian zebra mussel, the Eurasian water plant known as watermilfoil, the Eurasian spiny water flea, the rusty crayfish and the rainbow smelt. Such freshwater invaders often have direct negative effects on lake ecosystems, including reduced fishing success, changes in water clarity and fouling of fishing gear and water-pumping equipment, Johnson said.

The study appears as the cover story in the September issue of Frontiers in Ecology and the Environment, a publication of the Ecological Society of America. Co-authors on the study include Julian Olden of the University of Washington in Seattle and Jake Vander Zanden of the University of Wisconsin-Madison.Keep reading

Thawing Permafrost Likely To Boost Global Warming, New Assessment Concludes

ScienceDaily (Sep. 2, 2008) — A new assessment more than doubles previous estimates of the amount of carbon stored in permafrost, and indicates that carbon dioxide emissions from microbial decomposition of organic carbon in thawing permafrost could amount to roughly half those resulting from global land-use change during this century.

The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment.

The study, by Edward A. G. Schuur of the University of Florida and an international team of coauthors, more than doubles previous estimates of the amount of carbon stored in the permafrost: the new figure is equivalent to twice the total amount of atmospheric carbon dioxide. The authors conclude that releases of the gas from melting permafrost could amount to roughly half those resulting from global land-use change during this century. Keep Reading
