Latest Planetary engineering Stories
Giant â€œsynthetic treesâ€ that reflect heat back into the sky may become a common sight within the next 20 years, as the Institution of Mechanical Engineers sets out to combat the worldâ€™s climate change with cutting edge technology.
Climate experts say a fleet of wind-powered ships could be one of the more feasible solutions of climate engineering to reduce global warming.
Geoengineering techniques aim to slow global warming through the use of human-made changes to the Earth's land, seas or atmosphere. But new research shows that the use of geoengineering to do environmental good may cause other environmental harm.
Geoengineering - deliberately manipulating physical, chemical, or biological aspects of the Earth system to confront climate change â€“ could contribute to a comprehensive risk management strategy to slow climate change but could also create considerable new risks, according to a policy statement released by the American Meteorological Society (AMS) today.
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.
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
Plants absorbed carbon dioxide more efficiently under the polluted skies of recent decades than they would have done in a cleaner atmosphere, according to new findings published this week in Nature.
President Barack Obamaâ€™s science and technology director said on Wednesday that the controversial use of geoengineering needs to be considered an option for combating global climate change.
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.
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.
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...
