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. 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...

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. Climate Change Science Program on Friday.

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...

UCLA scientist sees many geoengineering plans as 'preposterous' 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. But Richard Turco, a professor in the UCLA Department of Atmospheric and Oceanic Sciences and a member and founding director of UCLA's Institute of the...

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. But many scientists believe the concept of using nature to mop up mankind's excess CO2 to fight global warming is fraught with risk and uncertainty. An Australian research body suggests more research is needed before commercial ventures are allowed to fertilize oceans on a large scale and over many years to...

Scientists are expanding the search for extraterrestrial life -- and they've set their sights on some very unearthly planets. Cold "Super-Earths" -- giant, "snowball" planets that astronomers have spied on the outskirts of faraway solar systems -- could potentially support some kind of life, they have found. Such planets are plentiful; experts estimate that one-third of all solar systems contain super-Earths. "We know there are a lot of super-Earths out there, and the next generation of...

The UK's Royal Society is conducting an investigation to determine if ambitious engineering schemes could reduce the impact of global warming. "Geo-engineering" experiments, such as putting mirrors into space and iron filings in oceans, are being proposed and the society says they must be properly assessed - however fantastical. Climate scientists and engineers' groups will study a variety of these ideas and produce a report by the middle of next year. However, environmental groups are...

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...
