Latest Planetary engineering Stories
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.
According to a report in Fridayâ€™s edition of the journal Science, skies all over the world are dimming due to increases in airborne pollution over the past 30 years.
Scientists in North America and Britain are working on a massive sun shade they say could be used to stop global warming. Roger Angel, an astronomer with the University of Arizona, has received funding from NASA to develop a canon that would fire trillions of mirrors into space to deflect the rays of the sun, Britain's Telegraph newspaper reported Friday. British inventor Tod Todeschini has been contracted to build a scaled-down version of the canon. Angel said he expects to be ready to...
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.
Certain geoengineering schemes could be complementary to proposed cuts in greenhouse gas emissions aimed at fighting global climate change, researchers reported on Tuesday.
WASHINGTON, Jan. 16 /PRNewswire-USNewswire/ -- Scientists need a more detailed understanding of how human-produced atmospheric particles, called aerosols, affect climate in order to produce better predictions of Earth's future climate, according to a NASA-led report issued by the U.S.

Researchers say that strategic farming practices might be part of the solution for curbing global warming.
Global warming, some have argued, can be reversed with a large-scale "geoengineering" fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide.
The icy seas between Australia and Antarctica could become a money generator by engineering nature to soak up carbon dioxide and then selling carbon credits worth millions of dollars.
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...
