Computer models show how skyborne seawater particles change cloud brightness, temperature, rain patterns Ships blowing off steam are helping researchers understand how manmade particles might be useful against global warming. New results from modeling clouds like those seen in shipping lanes reveal the complex interplay between aerosols, the prevailing weather and even the time of day the aerosol particles hit the air, according to research presented Saturday morning at the American...

Pumping nutrient-rich water up from the deep ocean to boost algal growth in sunlit surface waters and draw carbon dioxide down from the atmosphere has been touted as a way of ameliorating global warming. However, a new study led by Professor Andreas Oschlies of the Leibniz Institute of Marine Sciences (IFM-GEOMAR) in Kiel, Germany, pours cold water on the idea. "Computer simulations show that climatic benefits of the proposed geo-engineering scheme would be modest, with the potential to...

Climate change experts argue for international geoengineering effort Internationally coordinated research and field-testing on 'geoengineering' the planet's atmosphere to limit risk of climate change should begin soon along with building international governance of the technology, say scientists from the University of Calgary and the United States. Collaborative and government-supported studies on solar-radiation management, a form of geo-engineering, would reduce the risk of nations'...

Ecologists outline necessary actions for mitigating and adapting to a changing climate Global warming may impair the ability of ecosystems to perform vital services -- such as providing food, clean water and carbon sequestration -- says the nation's largest organization of ecological scientists. In a statement released today, the Ecological Society of America (ESA) outlines strategies that focus on restoring and maintaining natural ecosystem functions to mitigate and adapt to climate change....

While governments around the world continue to explore strategies for reducing greenhouse gas emissions, a new study suggests policymakers should focus on what needs to be achieved in the next 40 years in order to keep long-term options viable for avoiding dangerous levels of warming. The study is the first of its kind to use a detailed energy system model to analyze the relationship between mid-century targets and the likelihood of achieving long-term outcomes. "Setting mid-century targets...

Climate experts say geo-engineers are exploring radical new ways to combat Earth's climate crisis, including fertilizing the seas with iron, scattering particles in the stratosphere to reflect sunlight or building a sunshade in space, AFP reported. However, many of these ideas are contested as risky for the environment and laden with unknowns about cost, practicality and legality. But mainstream scientists who once dismissed these projects are now starting to consider their possibilities....

A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. Research has made little or no progress on this issue. Two scientists from the Max Planck Institute for Meteorology in Hamburg (MPI-M) and the American National Oceanic and Atmospheric Administration (NOAA) report in the journal...

NEW YORK, Sept. 24 /PRNewswire/ -- Reportlinker.com announces that a new market research report is available in its catalogue. Roofing Materials in the U.S., 2nd Edition http://www.reportlinker.com/p0109231/Roofing-Materials-in-the-US-2nd-Edition.html This new SBI report reveals astonishingly that roofing product manufacturing managed to grow modestly from $10.6 billion in 2007 to $10.9 billion in 2008, a gain of three percent. This is credited to increased asphalt pricing in 2008 and a...

The future of the Earth could rest on potentially dangerous and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, a new study has found.The report (published September 1, by the Royal Society, the UK's national academy of science) found that unless future efforts to reduce greenhouse gas emissions are much more successful than they have been so far, additional action in the form of geoengineering will be necessary to cool the planet. However, the...

Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering "“ deliberate interventions in the climate system to counteract man-made global warming "“ more seriously.Of increased importance, as policy makers and politicians prepare to negotiate binding carbon emission targets at December's United Nation's Convention on Climate Change in Copenhagen...

Terraforming -- Terraforming (literally, "Earth-shaping") is the process of modifying a planet, moon or other body to a more habitable atmosphere, temperature or ecology. The term was first used in a science fiction novel, 'Seetee Shock' (1940?) by Jack Williamson, but the actual concept is older than that. An example in fiction is 'First and Last Men' by Olaf Stapledon in which Venus is modified, after a long and destructive war with the original inhabitants, who naturally object to the...
