  Our understanding of how clouds form may need to be revised, according to new research published in the journal Nature. The study has found that one or more unidentified organic gases have a significant influence on the Earth's cloud cover. The research has implications for certain predictions about climate change because aerosol particles and the clouds they seed have a cooling effect on the Earth by reflecting radiation from the sun. Jasper Kirkby, head of the Cosmics...

Supercomputer simulations by University of Washington researchers outline the potential risks and benefits of geoengineering Scientists believe that our warming world may face catastrophic changes to its natural environment, including droughts, rising oceans and fiercer, more frequent hurricanes. Theoretically, it may be necessary to act globally to mitigate the damage. Initially, those efforts will probably take the form of limits on greenhouse gas emissions or forest preservation. But...

Volcanic ash from small-scale eruptions and soot resulting from the burning of fossil fuels may be responsible by slowing the rate of global warming up by to 20-percent, according to the results of a new National Oceanic and Atmospheric Association (NOAA) study released Thursday. Particles such as these, commonly referred to as "aerosols", can reflect sunlight back into space once they reach the stratosphere, which according to an NOAA press release, "leads to a cooling influence on the...

BEACHWOOD, Ohio, June 16, 2011 /PRNewswire/ -- Just over a year ago, Tremco Incorporated (Tremco) began a foundation-to-roof renovation of its 40-year-old headquarters into a showcase of sustainability that would achieve LEED® (Leadership in Energy and Environmental Design) Gold certification from the US Green Building Council's (USGBC). Tomorrow, Friday, June 17, 2011, the company marks the completion of this project with a formal unveiling and dedication of the newly...

According to new research, whitening clouds by spraying them with seawater could do more harm than good for climate change. Whiter clouds reflect more solar energy back into space, which inevitably cools the Earth. However a study presented at the European Geosciences Union meeting found that using water droplets of the wrong size would lead to warming, not cooling. One scientist said it should be possible to make sure droplets were the correct size. John Latham of the University...

Recent climate modeling has shown that reducing the concentration of carbon dioxide in the atmosphere would give the Earth a wetter climate in the short term. New research from Carnegie Global Ecology scientists Long Cao and Ken Caldeira offers a novel explanation for why climates are wetter when atmospheric carbon dioxide (CO2) concentrations are decreasing. Their findings, published online today by Geophysical Research Letters, show that cutting carbon dioxide concentrations could help...

Geoengineering schemes involving ocean fertilization to affect climate have a low chance of success, according to the first summary for policymakers on the issue. Failure to tackle rising greenhouse gas emissions effectively has led to intensifying debate on geoengineering - deliberate large-scale schemes to slow the rate at which Earth is heating up. The public debate often mixes opinion with fact so scientists have now released the first summary for policymakers on ocean fertilization, one...

Could Dimming the Sun Change Teleconnections in Weather Patterns as we Know Them? Solar radiation management projects, also known as sun dimming, seek to reduce the amount of sunlight hitting the Earth to counteract the effects of climate change. Global dimming can occur as a side-effect of fossil fuels or as a result of volcanic eruptions, but the consequences of deliberate sun dimming as a geoengineering tool are unknown. A new study by Dr Peter Braesicke, from the Centre for Atmospheric...

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...
