The Icelandic volcano eruption can cause severe damage to jet engines and slight warming in the atmosphere, said a Swedish climate expert.

Fred Goldberg, who used to teach in Swedish Royal Technology University(KTH), said severe damage may occur to jet engines when flying through volcanic ash.

"Because the eruption takes place through the ice, there is a very strong cloud of water vapour coming up. The cooling effect of the ice also solidifies small particles forming sharp glass-like particles which can cause severe damage to jet engines,' he said.

The current Icelandic eruption is not so strong and the ashes are therefore not thrown into the stratosphere but remaining in the troposphere at 5,000-10,000 meters, he explained.

The incoming sunlight will warm these ash particles, which in turn will warm the surrounding air and therefore it may cause a slight warming of the atmosphere, Goldberg predicted.
