Imported from Asia: OZONE
January 21, 2010 06:59 AM - Roger Greenway, ENN

Ever wonder how the western US has high ozone levels when the winds usually blow in off the Pacific Ocean? Did you think it was all from the cars clogging the freeways? Turns out, it is caused in part from emissions of ozone generating air emissions from Asia. A study by the National Oceanic and Atmospheric Administration (NOAA) shows that Springtime ozone levels above western North America are rising, primarily due to air flowing eastward from the Pacific Ocean, a trend that is most significant when the air originates in Asia.

Sinking Islands and Their Consequences

The recent devastation caused by the earthquake in Haiti is not the only environmental disaster the world face. A more long term one is the pending sea level rise that could obliterate the world's small island states, triggering fears of mass migration. However, a mass migration is not immediately likely and some of these small island nations are fighting back.

Himalayan glacier meltdown warning being reconsidered
January 20, 2010 06:28 AM - Jonathan Leake and Chris Hastings, The Sunday Times

A warning that climate change will melt most of the Himalayan glaciers by 2035 is likely to be retracted after a series of scientific blunders by the United Nations body that issued it. Two years ago the Intergovernmental Panel on Climate Change (IPCC) issued a benchmark report that was claimed to incorporate the latest and most detailed research into the impact of global warming. A central claim was the world's glaciers were melting so fast that those in the Himalayas could vanish by 2035.

Shipworms threaten archaeological treasures

The University of Gothenburg Department of Marine Ecology has found that shipworms are becoming a bigger threat to shipwrecks in the Baltic Sea. In a paper published by Christin Appelqvist and Jon Havenhand the research finds that the dreaded shipworm is moving into the Baltic Sea, threatening artifacts of the area's cultural heritage. Researchers at the University of Gothenburg suspect that the unfortunate spread is due to climate change, and are currently involved in an EU project to determine which archaeological remains are at risk.

Ski property faces meltdown as global warming chills the market
January 17, 2010 11:04 AM - Graham Norwood, Guardian UK, Environmental Health News

There may be a global freeze on at the moment but Britons who own and let flats and chalets at ski resorts could face a threat to their investments – thanks to a long-term shortage of snow. Recent weeks have seen huge snowfalls in the UK, on mainland Europe and across North America, but research by Unesco's environment programme suggests long-term global warming will push the snowline up worldwide in years to come.

Amazonian Biochar

Scientists are reporting that biochar, which is a material that the Amazonian Indians used to enhance soil fertility centuries ago, has the potential in the modern world to help slow global climate change. Mass production of biochar could capture carbon that otherwise would wind up in the atmosphere as carbon dioxide, the main greenhouse gas. Their report appears in ACS’ Environmental Science & Technology, a bi-weekly journal.

Is Antarctica melting, or not?
January 14, 2010 06:46 AM - Roger Greenway, ENN

NASA reports on a new analysis of the Antarctic ice sheet and its apparent response to global warming. NASA notes that one new paper states there has been less surface melting recently than in past years, and has been cited as “proof” that there’s no global warming. Other evidence that the amount of sea ice around Antarctica seems to be increasing slightly is being used in the same way. But both of these data points are misleading.

Icy Seas Continue in Antarctica

Sea water under an East Antarctic ice shelf showed no sign of higher temperatures despite fears of a thaw linked to global warming that could bring higher world ocean levels, first tests showed on Monday. Sensors lowered through three holes drilled in the Fimbul Ice Shelf showed the sea water is still around freezing and not at higher temperatures widely blamed for the break-up of 10 shelves on the Antarctic Peninsula, the most northerly part of the frozen continent.

Largest U.S. farm group rallies against climate bill
January 11, 2010 06:42 AM - Charles Abbott, Reuters

The largest U.S. farm group will oppose aggressively "misguided" climate legislation pending in Congress and fight animal rights activists, said American Farm Bureau Federation president Bob Stallman on Sunday. In a speech opening the four-day AFBF convention, Stallman said American farmers and ranchers "must aggressively respond to extremists" and "misguided, activist-driven regulation ... The days of their elitist power grabs are over."

Feedback Accelerates Arctic Ice Melt – Canada, Alaska Most Pronounced
January 10, 2010 10:30 AM - Thomas Schueneman, Global Warming is Real

Scientists at NASA and the National Snow and Ice Data Center published research last week in the Journal of Geophysical Research based on satellite microwave data of seasonal Arctic ice thaw from 1970 to 2009. The study indicates the seasonal Arctic sea ice melt melt season is now about 20 days longer than it was 30 years ago. The growing season of thaw is most pronounced in Arctic waters off the coasts of Alaska and Canada, including the Chukchi and Beaufort seas, where the season is 30 days longer now than in 1979. East Greenland and the Hudson Bay also share nearly a month longer of seasonal melt. The Hudson Bay exhibits one of the fastest increases in seasonal melt on the globe.
