A project funded by Microsoft founder Bill Gates is exploring the possibility of halting global warming by releasing dust into the atmosphere to block the sun’s rays. The proposed scheme, known as Stratospheric aerosol injection (SAI), would see more than 800 giant aircraft lift millions of tonnes of chalk dust to a height of 12 miles above the Earth’s surface every single day. Scientists believe that the dust would act like a giant sunshade, reflecting the sun’s rays back into space in order to cool the earth.

If, on the other hand, the world goes on burning fossil fuels under the notorious “business as usual” scenario, then according to new research the people of the planet could demand up to 58% more energy, just to drive the extra air conditioning and refrigeration in ever more frequent and ever more intense extremes of heat.
