Clarity in muddy debate over mud
December 13, 2007 03:20 PM - Indiana University Bloomington Newswire
BLOOMINGTON, Ind. -- Geologists have long thought muds will only settle when waters are quiet, but new research by Indiana University Bloomington and Massachusetts Institute of Technology geologists shows muds will accumulate even when currents move swiftly. Their findings appear in this week's Science.
This may seem a trifling matter at first, but understanding the deposition of mud could significantly impact a number of public and private endeavors, from harbor and canal engineering to oil reservoir management and fossil fuel prospecting.
Acid seas huge threat to coral reefs: study
December 13, 2007 02:15 PM - By Jim Loney, Reuters
MIAMI (Reuters) - In less than 50 years, oceans may be too acidic for coral reefs to grow because of carbon emissions from the burning of fossil fuels by humans, according to research released on Thursday.
Without insulating ice, Arctic waters warm 5 C

Seattle, Washington - Record-breaking amounts of ice-free water have deprived the Arctic of more of its natural "sunscreen" than ever in recent summers. The effect is so pronounced that sea surface temperatures rose to 5 C above average in one place this year, a high never before observed, says the oceanographer who has compiled the first-ever look at average sea surface temperatures for the region.
Asian desert dust found over western United States
December 13, 2007 01:14 PM - Vince Stricherz, University of Washington Newswire
Seattle, Washington - It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America.
Now a UW researcher is finding that dust from the Gobi and Taklimakan deserts in China and Mongolia is routinely present in the air over the western United States during spring months. "We are interested in Asian dust that comes across the Pacific because particles can have an impact on health, as well as on visibility," said Emily Fischer, a UW doctoral student in atmospheric sciences.

AMSTERDAM (Reuters) - Dutch company BioX Group and environment body Wetlands International launched a fund at a U.N climate meeting in Bali this week that aims to cut greenhouse gas emissions by investing in restoration of peatlands.
Namibia's poor 'will be hit hard' by climate change
December 13, 2007 12:50 PM - Carol Campbell, SciDevNet
Namibia, Africa - Climate change is expected to dramatically alter the lifestyles of poor people in Namibia, say the authors of a study. Their findings were published by the UK-based International Institute for Environment and Development (IIED) this month (December).
Namibia is economically dependent on natural resources. Up to 30 per cent of its gross domestic product (GDP) is estimated to be reliant on the environment. Climate change could increase temperatures by 2–6 degrees Celsius by 2100, and rainfall is expected to be lower and more variable.

Al Gore lays blame for Bali stalemate on U.S.
December 13, 2007 09:50 AM - Reuters
NUSA DUA, Indonesia (Reuters) - Former U.S. Vice President Al Gore drew cheers at 190-nation talks by saying the United States was the main block to launching negotiations in Bali on a new global climate treaty.
Efforts to start two-year negotiations on a pact to succeed the Kyoto Protocol flagged on Thursday, the penultimate day of the December 3-14 talks, after the European Union accused the United States of lacking ambition.
Indigenous people fear double climate hit
December 13, 2007 09:12 AM - Reuters
NUSA DUA, Indonesia (Reuters) - Indigenous people already struggling to cope with a warming world risk losing their homes under rich-world schemes to tackle climate change by using forests as carbon sinks, activists said on Thursday.
Groups that have been custodians of forests for generations fear projects will undermine their ownership of traditional areas, enforce land-grabs by corrupt regimes, encourage more theft, undermine biodiversity and exclude them from management.
