Four expert speakers attended an event organized by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on 15 July, at the House of Commons, to address an audience curious about geo-engineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises. Introduced by Dr Brian Iddon MP, Dr Alan Gadian from the University of Leeds opened the seminar with a description of cloud albedo modification, explaining...

SAN JUAN, Puerto Rico, June 23 /PRNewswire/ -- Caribbean Sunlife Specialties Corp. (CSSC), a Puerto Rico-based industrial roofing contractor announced today that the U.S. Patent for its "Non-Invasive Metal Roof Deck Securement Enhancement System" has been issued. This non-invasive retrofit method to strengthen existing roof structures is highly cost effective and has minimal impact on the operations of the building during retrofit. The retrofit roof securement system has been installed on...

Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life, report the authors of a new study in the journal Geophysical Research Letters*. The culprit is atmospheric carbon dioxide, which even in a cooler globe will continue to be absorbed by seawater,...

Roofing Contractor Meets Strict Time Constraints Set by Wineries' Crush Season CONCORD, Calif., April 16 /PRNewswire/ -- D. C. Taylor Co. announced its role as roofing contractor for the solar energy project hosted at four of the Foster's Wine Estates. Due to strict time constraints set by the wineries' annual crush (harvest) season, the 400,000 square-foot roofing project began in August 2008 and finished in October 2008. D. C. Taylor Co. employed nine separate crews totaling 55 workers...

President Barack Obama's science and technology director told the Associated Press on Wednesday that the controversial use of geoengineering needs to be considered an option for combating global climate change. "It's got to be looked at," said Holdren in his first interview since being confirmed. "We don't have the luxury of taking any approach off the table." Geoengineering involves manipulation of the environment on a large scale using methods such as fertilizing the Earth's oceans with...

Scientists in Germany and India said an experiment to determine whether depositing hundreds of tons of dissolved iron in the Southern Ocean can diminish global warming has produced disappointing results. In conducting the research, scientists "fertilized" a 115 square mile area of ocean by placing six tons of dissolved iron inside the core of an eddy -- a large, rotating column of water. The researchers hoped the iron would stimulate the growth of tiny planktonic algae known as phytoplankton,...

British scientists say they are looking for ways to reduce global temperatures and curb greenhouse emissions through geo-engineering. Researchers are looking into the feasibility of using artificial trees to absorb carbon dioxide or reflect sunlight away from Earth, the Times of London reported Sunday. The Royal Society, Britain's national academy of science, is preparing a report on the subject, the newspaper said. Our study aims to separate the science from the science fiction and offer...

A team of scientists led by the University of Minnesota has discovered that iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor. The study, published in the journal Nature Geoscience, connects life at the surface to events occurring at extreme depths and pressures"”two worlds long assumed to have little interaction. Brandy Toner, an assistant professor in...

Certain geoengineering schemes could be complementary to proposed cuts in greenhouse gas emissions aimed at fighting global climate change, researchers reported on Tuesday. A team of researchers from Britain's University of East Anglia conducted the first study to determine the climate cooling potential of various geoengineering schemes Geoengineering involves manipulation of the environment on a large scale using methods such as fertilizing the Earth's oceans with nutrients or using giant...

Researchers say that strategic farming practices might be part of the solution for curbing global warming. According to calculations reported online on 15 January in Current Biology, a Cell Press publication, by planting crop varieties that better reflect sunlight back out to space, summertime temperatures could be reduced by more than one degree Celsius throughout much of central North America and mid-latitude Eurasia. That reduction is equivalent to seasonally offsetting about 20 percent of...

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...
