Latest Planetary engineering Stories
New research led by astronomers and astrophysicists from the University of Warwick has found evidence in asteroid debris explaining how water reached Earth, and their research indicates that our planet is not alone in the amount of H2O it contains.
Harvard scientists say aspects of solar geoengineering can — and should — be tested without need for full-scale deployment.
Of all the factors that influence Earth's changing climate, the effect that tiny particles in Earth's atmosphere called aerosols have on clouds is the least well understood.
Tinkering with climate change through climate engineering isn't going to help us get around what we have to do says a new report authored by researchers at six universities, including Simon Fraser University.
In a region of the Southern Ocean, iron fertilization caused plankton to thrive during the last ice age, according to a new study from Princeton University and the Swiss Federal Institute of Technology in Zurich.
Researchers at Lawrence Livermore National Laboratory report they have found that volcanic eruptions in the early part of the 21st century have cooled the planet.
A proposed mitigation technique which involves spewing sulfur particles into the atmosphere could help combat climate change – but if stopped after being implemented, it could worsen the problem, University of Washington researchers warn.
As a range of climate change mitigation scenarios are discussed, University of Washington researchers have found that the injection of sulfate particles into the atmosphere to reflect sunlight and curb the effects of global warming could pose a severe threat if not maintained indefinitely and supported by strict reductions in greenhouse gas (GHG) emissions.
A special issue of the journal Climate Change, titled “Geoengineering Research and its Limitations,” addresses these technologies, as well as barriers, ethics and regulations.
Geoengineering the climate has been suggested as a way to be able to help lessen the impact of climate change, but new research published in Earth System Dynamics says this approach would not likely succeed.
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...
