Sunscreen, the human mechanism to fight the sun's scorching heat maybe experimented on the atmosphere too.
Harvard researches have suggested that "stratospheric aerosol injection" or solar engineering would be a possible way to counter rising global warming.
“Solar geoengineering – injecting aerosol particles into the stratosphere to reflect away a little inbound sunlight – is being discussed as a way to cool the planet, fast,” explain leading scientists.
Basically, the suggestion is to create a gaseous sunshade for the earth to protect it from rising global temperatures.
While scientists have claimed solar geoengineering to be outlandish and unsettling as it involves technologies used in science-fiction, they have said that such approaches could be realised technically and politically.
"The technique is controversial, and rightly so. It is too early to know what its effects would be: it could be very helpful or very harmful. Developing countries have the most to gain or lose. In our view, they must maintain their climate leadership and play a central part in research and discussions around solar geoengineering," said scientists to Nature magazine.
The process would involve jets lacing the stratosphere with sunlight-blocking particles, and fleets of ships spraying seawater into low-lying clouds to make them whiter and brighter to reflect sunlight, which does paint a future sci-fi adventure major movie houses may foray into.
People have taken to Twitter to either panic over sun shading earth or to promote the sci-fi vision.
