Sounds like something coming directly from a science fiction movie, but it isn’t, Bill Gates, the Billionaire business mogul who founded Microsoft is saying that his plan to put a ‘shade’ around Earth will be able to save us from the effects of Climate change. Bill Gates is partially funding this project and a team of experts and scientists are advising and taking care of this project.
The inspiration for this idea came to scientists after a natural disaster hit. When the volcano Mount Pinatubo in the Philippines exploded in 1991 it created a massive cloud in the sky which persisted for years and climatologists believe that global temperatures were reduced by 0.5c for around a year and a half from this event only.
Scientists are thinking about starting a small scale experiment first, they are planning to use a high-altitude scientific balloon to raise around 2kg of calcium carbonate dust, which is around the size of a bag of flour, into the atmosphere above the desert of New Mexico and then study the effects on a small area of land.
However not everyone agrees that we should just spray this all around Earth, some experts are saying that such a procedure might trigger a disastrous series of chain reactions, creating climate havoc in the form of serious droughts and hurricanes, and bring death to millions of people around the world.
In the meantime a an advisory panel of independent experts is expected to assess all the possible risks associated with this plan even before the small scale experiment is conducted.
In theory, the airborne chalk or fine dust would create a gigantic sunshade around us, reflecting some of the Sun’s rays and heat back into space and thus dimming the effects of the sun and in so doing protecting the Earth from the worsening ravages of climate warming.
It has been argued that regardless of the economic, scientific and technical aspects, the difficulty of achieving concerted political action on global warming requires other approaches. Those arguing political expediency say the difficulty of achieving meaningful emissions cuts and the effective failure of the Kyoto Protocol demonstrate the practical difficulties of achieving carbon dioxide emissions reduction by the agreement of the international community.
However, others point to support for climate engineering proposals among think tanks with a history of global warming denial and opposition to emissions reductions as evidence that the prospect of climate engineering is itself already politicized and being promoted as part of an argument against the need for (and viability of) emissions reductions; that, rather than climate engineering being a solution to the difficulties of emissions reductions, the prospect of climate engineering is being used as part of an argument to stall emissions reductions in the first place.
