NYC Will Deploy Temporary Snake-Like Barriers & ‘Tiger Dams’ to prevent flooding
As atmospheric warming gallops forward, and as the waters rise all around us, hurricane season poses an increasingly dire threat to NYC. With calamity looming in the near-to-middle future, the city has long-term plans to fortify Manhattan’s lower half to thwart tides and storm ...

Satellite imagery shows fragile Wilkins Ice Shelf destabilised
Satellite images show that icebergs have begun to calve from the northern front of the Wilkins Ice Shelf – indicating that the huge shelf has become unstable. This follows the collapse three weeks ago of the ice bridge that had previously linked the Antarctic mainland to Charcot Island. The ice bridge, which effectively formed a barrier pinning back the northern ice front of the central Wilkins ...

Himalayan pollution `could impact monsoon cycle`
Researchers have shown that pollution from China, India, Nepal and Pakistan can reach altitudes of over 5,000 metres in the Himalayas, contributing to the warming of the atmosphere and potentially affecting the South-East Asian monsoon cycle. They also found that new aerosol particles — ultrafine particles suspended in the atmosphere — can form at these heights. The ...

HSM organises the 6th partner conference at Lake Constance
HSM, the German office and environmental technology manufacturer announces the 6th international partner conference at Lake Constance. From 30th June to 2nd July 2010 HSM sales partners from all over the world gather to meet the HSM sales team and HSM senior management. Altogether there were roughly 120 participants from 38 countries who contributed to making this partner conference a great ...

Antarctica could raise sea level faster than previously thought
Ice discharge from Antarctica could contribute up to 37 centimeters to the global sea level rise within this century, a new study shows. For the first time, an international team of scientists provide a comprehensive estimate on the full range of Antarctica’s potential contribution to global sea level rise based on physical computer simulations. Led by the Potsdam Institute for Climate ...

The warmer the higher: sea-level rise from Filchner-Ronne ice in Antarctica
The more ice is melted of the Antarctic Filchner-Ronne shelf, the more ice flows into the ocean and the more the region contributes to global sea-level rise. While this might seem obvious, it is no matter of course for the huge ice masses of Antarctica: parts of the ice continent are characterized by instabilities that, once triggered, can lead to persistent ice discharge into the ocean even ...

Arctic sea ice shrinks to record low
Researchers in the US say that Arctic sea ice has reached a record low winter maximum for the second year running. Data from the US National Snow and Ice Data Center (NSIDC) and the US space agency NASA shows that the sea ice peaked on 24 March at 5.607 million square miles, or 14.52 million square kilometers. This is the lowest maximum since satellite measurements began in 1979. ...

RTO cleans methane from coal mining
Using a Regenerative Thermal Oxidizer to convert methane into carbon dioxide may prove a deterrent to Global Warming. Everybody's talking about clean coal. Vanishing are the images of smog-filled towns and blackened valleys of soot that made coal a byword for dirty fuel. In fact, like it or not, coal still produces about half of U.S.-produced electricity and about a quarter of the electricity ...

Asian Brown Clouds Intensify Global Warming
SAN DIEGO, California, August 1, 2007 (ENS) - Brown clouds of pollution over South Asia have multiplied solar heating of the lower atmosphere by 50 percent, finds new research by scientists at Scripps Institution of Oceanography at the University of California-San Diego. The combined heating effect of greenhouse gases and the brown clouds is necessary and sufficient to account for the retreat of ...

Ocean salinities show an intensified water cycle
The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. The study, co-authored by CSIRO scientists Paul Durack and Dr Susan Wijffels, shows the surface ocean beneath rainfall-dominated regions has freshened, whereas ocean regions dominated by evaporation are saltier. The paper also confirms that surface warming of the ...

Climate change brings ill winds for airline industry
Global warming may already be taking its toll of air miles. As jet planes burn fuel and release carbon dioxide, the atmosphere warms and causes head winds to build up. Tail winds do too, but round trip journey times are nevertheless creeping up − and so are fuel costs. A team of US scientists say the cumulative effect of the longer flight times that they think may have resulted from ...

Rising temperatures and acidification in the oceans spell danger for shark populations
Increasing temperatures and rising ocean acidification could reduce the health and survival of young sharks, new research has shown. Bamboo shark embryos incubated under ocean temperatures and acidity predicted for 2100 showed survival rates of 80% compared to 100% survival under present-day conditions. Once hatched, survival measured at 30 days was only 44% for those under predicted climate ...

When times are tight, focus on adaptation
In a commentary article in the journal Nature Climate Change, US, Spanish and Australian researchers submit that biologists should, instead, aim to achieve a balance between understanding climate change impacts and planning for the consequences. “There is little point in focussing on fully identifying the climate impacts while losing species,” says co-author Dr Elvira Poloczanska, an ...

Ocean Absorption of Carbon Dioxide More than Makes Up for Methane Emissions from Seafloor Methane Seeps
The ocean waters near the surface of the Arctic Ocean absorbed 2,000 times more carbon dioxide from the atmosphere than the amount of methane that escaped into the atmosphere from the same waters, according to a study by the USGS Gas Hydrates Project and collaborators in Germany and Norway. The study was conducted near Norway’s Svalbard Islands, above several seafloor methane seeps. ...

Ocean fertilization `fix` for global warming discredited by new research
Research performed at Stanford and Oregon State Universities suggests that ocean fertilization may not be an effective method of reducing carbon dioxide in the atmosphere, a major contributor to global warming. Ocean fertilization, the process of adding iron or other nutrients to the ocean to cause large algal blooms, has been proposed as a possible solution to global warming because the growing ...

Scientists debate the accuracy of Al Gore’s documentary An Inconvenient Truth
There is no question that Al Gore’s 2006 documentary An Inconvenient Truth is a powerful example of how scientific knowledge can be communicated to a lay audience. What is up for debate is whether it accurately presents the scientific argument that global warming is caused by human activities. Climate change experts express their opinions on the scientific validity of the film’s claims in ...

Combating desertification could help tackle other global crises
While global attention is focused on crises ranging from energy to food security to climate change, a senior United Nations environmental expert highlighted the “silent” crisis of desertification or land degradation, which, if tackled properly, can actually help address these other issues. “The land can be… an opportunity to solve most of the ongoing global crises,” Luc Gnacadja, Executive ...

Distinguishing coincidence from causality: connections in the climate system
Detecting how changes in one spot on Earth – in temperature, rain, wind – are linked to changes in another, far away area is key to assessing climate risks. Scientists now developed a new technique of finding out if one change can cause another change or not, and which regions are important gateways for such teleconnections. They use advanced mathematical tools for an unprecedented ...
