The eventual plan is for a helium balloon the size of Wembley Stadium to be tethered 14 miles above the Earth by a giant hose, which will pump out tonnes of chemical particles into the stratosphere.
It is hoped that the droplets of sulphates and aerosol particles will reflect the sun's energy back into space, preventing it from heating the earth.
The concept is based on the similar cooling effect of volcano eruptions on the atmosphere.
Before embarking on the full project known as 'Spice' - Stratospheric particle injection for climate engineering - the team will conduct feasibility tests with a miniature version of the technology.
Backed by a Â£1.6million government grant and with the support of the Royal Society, the team hopes to follow up on the initial tests with full-scale radiation experiments on the equipment, which will operate at twice the altitude of commercial planes.
The tests, scheduled for October, are not expected to have any environmental impact but environment groups in Britain and the U.S. said the eventual deployment of such a system could be dangerous, with the potential to affect rainfall and harm food supplies.
Geo-engineering is seen as a 'plan B' against climate change, to come into effect if the global agreements on reducing greenhouse gasses fails.
But this proposed solution, known as solar radiation management (SRM), is just one strand of geo-engineering.
'There are two types of geo-engineering, one is this type of solar radiation management, and the other is carbon removal - taking carbon out of the atmosphere and storing it somewhere, perhaps underground.
'We are in a position now where we have to seriously look at the carbon removal option, but we don't support solar radiation management because we just don't know enough about the risks.'

Carbon removal? Excuse me? As a carbon base life form I strongly object
