Altered weather patterns worsened the effects of the eruption by causing ash clouds to stay over Europe for a longer period, according to Christophe Cassou and Eric Guilyardi of the European Centre for Research and Advanced Training in Scientific Computation in Toulouse, France.
The scientists have developed a climate model which shows that western winds common in the area are currently being blocked by a high-pressure weather system. Because of this, more and more ash-laden air is being blown over Europe.
"We predict that the frequency and length of blocking events will increase in a warmer climate," Cassou was quoted as saying by the New Scientist.
The eruption on the Eyjafjallajokull Glacier in Iceland, which began last Wednesday, has paralyzed air traffic throughout central and northern Europe, leaving thousands of travelers stranded and forcing more than 20 European countries to close their airspace.
Of course it must be true because computer models say so and they are never
