That helps form clouds and reflects sunlight, cooling the surface of the planet.

The basic concept is the same as that underpinning the "white roads" idea -- the development of a technology that can reflect a proportion of the sun's radiation away from the earth's surface and back out into space, thereby cooling the atmosphere and slowing, or even reversing the damaging effects of global climate change.

Finally, three major available global surface temperature record sources report a steady-to-cooling trend since 2001.

However, that conclusion appears to significantly overestimate the volcano signal because the models predicted deep and large cooling spikes associated with eruptions which are observed to be much smaller in global surface temperature records.

The firm said the construction phase would create hundreds of new jobs while the surface mine site could be tapped for geothermal energy to provide heating and cooling for the homes.

In 2003, Stanford University spin-out company Cooligy showed off its Active Micro-Channel Cooling (AMC) technology which allowed fluids to circulate through hundreds of tiny channels on the upper surface of a chip.
