"Parts of Portugal and Spain are the driest they have been in a thousand years
due to an atmospheric high-pressure system driven by climate change, according
to research published Monday, warning of severe implications for wine and olive
production.
The Azores High, an area of high pressure that rotates clockwise over parts of
the North Atlantic, has a major effect on weather and long-term climate trends
in western Europe.
But in a new modelling study published in the journal Nature Geoscience,
researchers in the United States found this high-pressure system "has changed
dramatically in the past century and that these changes in North Atlantic
climate are unprecedented within the past millennium".
Using climate model simulations over the last 1,200 years, the study found that
this high-pressure system started to grow to cover a greater area around 200
years ago, as human greenhouse gas pollution began to increase.
It expanded even more dramatically in the 20th century in step with global
warming."
