Could dimming the sun help to cool the Earth? Bill Gates wants to spray millions of tonnes of CHALK into the stratosphere to reflect sunlight and slow global warming - but critics fear it could be disastrous
- The project will see a test balloon launch this summer from the town of Kiruna
- It will send 2kg of chalk into the stratosphere 12 miles above the Earth's surface
- Scientists will then monitor who the dust particles interact with the atmosphere
- This will be fed into computer models to predict how a larger plume would work
- The idea is to 'block out' some of the sun's energy to cool down the Earth
Bill Gates wants to spray tonnes of CHALK into the stratosphere
Harvard University experts will send a large balloon 12 miles above the Swedish town of Kiruna and have it drop 2kg of chalk dust into the stratosphere.
