Asteroid Dust Could Fight Climate Change on Earth


Charles Choi

To combat global warming, scientists in Scotland now suggest an out-of-this-world solution — a giant dust cloud in space, blasted off an asteroid, which would act like a sunshade for Earth.

The world is warming and the climate is changing. Although many want to prevent these shifts by reducing emissions of greenhouse gases that trap heat from the sun, some controversially suggest deliberating manipulating the planet’s climate with large-scale engineering projects, commonly called geoengineering.

Instead of altering the climate by targeting either the oceans or the atmosphere, some researchers have suggested geoengineering projects that would affect the entire planet from space. For instance, projects that reduced the amount of solar radiation Earth receives by 1.7 percent could offset the effects of a global increase in temperature of 3.6 degrees F (2 degrees C). The United Nations’ Intergovernmental Panel on Climate Change (IPCC) has noted climate models suggest average global temperatures will likely rise by 2 to 11.5 degrees F (1.1 to 6.4 degrees C) by the end of this century.

  1. All you people with science degrees who know what is best for this planet please take that degree and shove it where the sun dont shine. Then eat a fucking bullet! I am so sick of all these assholes with a piece of paper that know better then the four billion years of evolution! What happens if these assholes put us into an ice age? What happens if it screws up and does something even worse? We got these pricks smashing genes together that have no business messing with this shit in the first place. Now there seeds are patented and it seems they cause mass cancers on a global scale. I am just starting to learn all the side effects of round up. Turns out this mundane product isn’t so mundane!

    Leave the planet to the man who created it! I was born and have a right to exist along with every other man women and child on this planet. We need to stop messing with nature or trying to improve it!
