Alaska's northern coast eroding with alarming speedSeptember 28th, 2009 WASHINGTON - A new video of time-lapse photographs has shown that the sea is eating away at Alaska's northern coast with alarming speed. According to a report in National Geographic News, scientists say that although the Beaufort Sea coastline has been receding for millennia, a marked increase in the rate of erosion over the last century is a concern.
World's low-lying river deltas sinking due to human activitySeptember 21st, 2009 WASHINGTON - A new study has indicated that most of the world's low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. Researchers at the University of Colorado at Boulder, US, led the study.
Sea levels rose as much as 2 feet this summer along the US East CoastSeptember 12th, 2009 WASHINGTON - Reports indicate that sea levels rose as much as 2 feet (60 centimeters) higher than predicted this summer along the US East Coast, surprising scientists who forecast such periodic fluctuations. According to National Geographic News, though the immediate cause of the unexpected rise has now been solved, the underlying reason remains a mystery.
20 million Bangladeshis at risk from rising sea levels in coming decadesSeptember 8th, 2009 LONDON - A new research has determined that up to 20 million people in low-lying Bangladesh are at risk from rising sea levels in the coming decades. According to a report by BBC News, the predictions come from the Centre for Environmental and Geographic Information Services (Cegis) in Bangladesh.
Carbon monoxide exposure may up heart problem risk for the elderlySeptember 1st, 2009 WASHINGTON - Carbon monoxide exposure has been found to elevate the risk of hospitalisation for the elderly with heart problems in an American study. The nationwide study of 126 urban communities has shown that an increase in carbon monoxide of 1 part per million in the maximum daily one-hour exposure is linked with a 0.96 percent increase in the risk of hospitalisation from cardiovascular disease among people over the age of 65.
Manure major contributor to rising nitrous oxide levels in atmosphereAugust 31st, 2009 SYDNEY - A new study has found manure is the major contributor to rising nitrous oxide levels since the beginning of last century. According to a report by ABC Science, the study was carried out by soil scientist and study author Dr Eric Davidson from the Woods Hole Research Centre in Massachusetts, US.
High sea levels along the East Coast in early summer blamed on wind, current changeAugust 31st, 2009 Wind, current combined to raise E Coast sea levelWASHINGTON — Folks living along the East Coast were in higher water early this summer thanks to a change in the wind and current flow. The National Oceanic and Atmospheric Administration said Monday the higher than normal sea levels were caused by persistent winds from the northeast — pushing water toward shore — and a weakening of the Florida current that feeds water into the Gulf Stream.
Women with high testosterone levels more likely to choose risky careersAugust 25th, 2009 WASHINGTON - Women with high testosterone levels are more likely to make risky career choices, according to a new study. Previous studies have shown that testosterone enhances competitiveness and dominance, reduces fear, and is associated with risky behaviours like gambling and alcohol use.
Identifying archaeological sites most at risk from climate change along England's coastJuly 9th, 2009 LONDON - A new study is going to determine the archaeological sites along the coast of England which are most at risk from the impacts of climate change. The effects of climate change, including rising sea level and coastal erosion, as well as other factors such as coastal development and shoreline management initiatives, constantly threaten archaeological sites along the coast of England.
US to suffer serious effects from climate changeJune 16th, 2009 WASHINGTON - The US is already being struck by the effects of climate change and the threats will only grow if the world does not speed up its efforts to reduce pollutants blamed for rising temperatures, the US government warned Tuesday. In a much-anticipated report that was compiled over years by US agencies and independent scientists, the government painted a broad picture of the threats that the United States faces from climate change.
Caribbean coral reefs 'flattened' over last 40 years, say scientistsJune 10th, 2009 WASHINGTON - A new study by researchers at the University of East Anglia (UEA), UK, has determined that coral reefs throughout the Caribbean have been comprehensively 'flattened' over the last 40 years. The collapse of reef structure has serious implications for biodiversity and coastal defences - a double whammy for fragile coastal communities in the region.
Height of large sea waves changes according to monthMay 30th, 2009 WASHINGTON - Scientists have used a 'non- seasonal' statistical model to determine that the height of large waves in the sea can change according to the month. "Anybody who observes waves can see that they are not the same height in winter and summer, but rather that their height varies over time, and we have applied a 'non- seasonal' statistical model in order to measure extreme events such as these," said Fernando J.
Flooding forces Alaska gov to nix East Coast trip, including White House Correspondents DinnerMay 8th, 2009 Palin to skip White House Correspondents DinnerJUNEAU, Alaska — Flooding in her home state has forced Alaska Gov. Sarah Palin to cancel an appearance at the White House Correspondents Dinner.
Increasing CO2 in oceans will make it harder for deep-sea animals to "breathe"April 18th, 2009 WASHINGTON - A new study has suggested that increasing carbon dioxide (CO2) and decreasing oxygen in the oceans will make it harder for deep-sea animals to "breathe". The study, by marine chemists at Monterey Bay Aquarium Research Institute (MBARI), US, suggests that low-oxygen "dead zones" in the ocean could expand significantly over the next century.
Rising CO2 may benefit world's coastal wetlandsMarch 24th, 2009 WASHINGTON - In a paradoxical finding, scientists have discovered that an increase in carbon dioxide (CO2) may ironically counterbalance some of its negative effects on coastal wetlands, which are the planet's most valuable ecosystems. The team conducted their study for two years (2006 - 2007), during which they focused on the role that organic matter, both growing and decaying, plays on soil elevation in wetlands and the effect CO2 has on this process.
