Hum Posted October 1, 2012 Share Posted October 1, 2012 A a group of scientists in Scotland are publishing a paper in the journal Advances in Space Research that contemplates using asteroid dust to shield the Earth from solar radiation, thus mitigating the effects of global warming. The idea has some problems, however. The plan, according to Space.com, would be to capture an asteroid -- 1036 Ganymed, for preference -- and use a mass driver to throw out material from it to move it to the L1 point, the Earth Moon Lagrange Point that lay directly between the Earth and moon. Then the same mass driver would create a stream of asteroid dust that would surround the Earth and block out enough solar radiation to cancel out the effects of global warming, giving the world enough time to switch from a carbon based energy economy to something else. According to JPL, 1036 Ganymed is the largest known Earth-approaching asteroid, with a diameter of about 32 kilometers. It is an S type asteroid, meaning that it is composed of metallic iron mixed with iron- and magnesium-silicates. Space.com states that the asteroid has a mass of 130 million-billion kg. Using it as a source of a dust shield would create a cloud of 5 million-billion kilograms stretching about 2,600 kilometers wide. According to Space.com, the scientists behind the proposal concede that politically moving such an enormous mass close to Earth would be difficult at best. An accident or a miscalculation could cause 1036 Ganymed to hit the Earth, which would end human civilization :| and likely a considerable amount of the biosphere. more Link to comment Share on other sites More sharing options...

Solid Knight Posted October 1, 2012 Share Posted October 1, 2012 The easiest way to end global warming is to build a super big A/C that vents into space. f0rk_b0mb and crispkreme 2 Share Link to comment Share on other sites More sharing options...
Rippleman Posted October 1, 2012 Share Posted October 1, 2012 global warming is a temporary condition It happens from time to time just like the Ice ages. Once you have this "dust" shield, you would then also have to remove it (or clean it up) once the earth started to cool again. The earth has looked after itself for 4 billion years, i figure it can handle this global warming thing on its own. We, on the other hand, will just have to hang in there and enjoy the ride nature takes us on. This one sadly is beyond our control for now. bguy_1986 and Phouchg 2 Share Link to comment Share on other sites More sharing options...

Im no rocket scientist but i think there might be a tiny chance that pumping 26 gigatonnes of CO2 per year into earths atmosphere might have an effect on our climate :/ Link to comment Share on other sites More sharing options...

Humans causing global warming is like saying ants are killing the US transportation infrastructure. http://news.discovery.com/earth/volcanoes-co2-people-emissions-climate-110627.html Despite statements made by climate change deniers, volcanoes release a tiny fraction of the amount of carbon dioxide emitted by human activities every year.In fact, humans release roughly 135 times more carbon dioxide annually than volcanoes do, on average, according a new analysis. Put another way, humans emit in under three days the amount that volcanoes typically release in a year, according to the best estimates of volcanic emissions.

JaredFrost Posted October 1, 2012 Share Posted October 1, 2012 Im no rocket scientist but i think there might be a tiny chance that pumping 26 gigatonnes of CO2 per year into earths atmosphere might have an effect on our climate :/ While true, that same CO2 was in the atmosphere previously hundreds of millions of years ago, life continued and thrived, whether it's human life is another question. But the planet itself will go on, with or without humans, and with the chance of causing a possible extinction level event, I think we should look for another method. I have no suggestions either.

Humans causing global warming is like saying ants are killing the US transportation infrastructure. Not true! Here is a quote from NewScientist: "Finally, claims that volcanoes emit more CO2 than human activities are simply not true. In the very distant past, there have been volcanic eruptions so massive that they covered vast areas in lava more than a kilometre thick and appear to have released enough CO2 to warm the planet after the initial cooling caused by the dust. But even with such gigantic eruptions, most of subsequent warming may have been due to methane released when lava heated coal deposits, rather than from CO2 from the volcanoes. Measurements of CO2 levels over the past 50 years do not show any significant rises after eruptions. Total emissions from volcanoes on land are estimated to average just 0.3 Gt of CO2 each year - about a hundredth of human emissions." So there you have it - humans produce 99 times more CO2 each year than volcanoes. Fact. Stop spreading anti-science propaganda.

So you believe that the 97% of scientists who agree that climate change is man-made are corrupt, yet somehow the 3% who disagree aren't? :rolleyes: Following that logic, I could simply argue that the 3% who disagree are on the payroll of the fossil fuel industry - in fact there is evidence to support that. Further, is it not more likely that media organisations and politicians are being funded by the fossil fuel industry and therefore have a vested interest in discrediting climate science? Your denial of observable fact and common sense is astounding. Oh well, another one for my ignore list. shakey 1 Share Link to comment Share on other sites More sharing options...
