Airborne volcanic ash can reflect the Sun's rays back into space and thereby contribute to cooling the planet.

Each volcanic event distributed ash with a unique set of properties (shape and color of particles, chemical signature).

PRINCETON When airports across Europe reopened after the closure caused by the eruption of Iceland s Eyjafjallajökull volcano, it was not because the amount of ash in the atmosphere had dropped, but because the risk that the ash posed to airplane safety had been reassessed.

Most of the town still lies under metres of ash, and the capital has been moved to nearby Kokopo.

Volcanic ash is contained in some layers, and can be used to establish the time of the layer's formation.

But the indications can be pretty unreliable, as an alternative version of the rhyme shows If the oak is out before the ash, 'Twill be a summer of wet and splash If the ash is out before the oak,'Twill be a summer of fire and smoke.

But there was no evidence that the more widely dispersed ash blowing over Europe from Iceland would cause similar problems.
