Volcanic ash disrupts flights over UK

The surprising news that volcanic ash is causing chaos at airports across much of the UK is dominating headlines today.

It is reported that the rock, glass and sand in the ash could clog up plane engines and potentially bring down flights. The eruption in the Eyjafjallajoekull area is the second to occur in a month and is unusual because it has thrown ash much higher into the atmosphere. the ash has since drifted over the UK and is heading south.

This eruption will obviously cause lots of disruption, but volcanoes have been causing problems particularly for the Earth’s climate for millions of years. For example when the volcano Tambora erupted in 1815 the world experienced a ‘year without a summer’ because the ash reflected much of the Sun’s rays back out into space.

Massive volcanic eruption are associated with the end Permian mass extinction 250 million years ago and the Cretaceous/Tertiary mass extinction 65 million years ago when the dinosaurs and many other plants and animals became extinct.

  2. It’ll be worth keeping an eye on the sunset tonight. This type of material in the atmosphere can create some impressive “red sky”.
