"Perched between brooding mountains and surrounded by vineyards, the Portuguese town of Vila Real may seem a world away from the chaos of central London."
First noted on BldgBlog, a recent article in the Guardian looked at London in the year 2071 from a climate change point of view, and estimated that it's climate then would resemble that of Portugal now.
They warn that average temperatures across Britain will reach 3C higher than today, peaking at 5C higher in the south-east. Night will offer little respite.
Each 1C of warming takes an extra hour to dissipate, so the south could feel as warm at midnight on summer evenings as it does at 7pm today. Summer rain on the south coast could be down to just half current levels, well over 40% down across the rest of England and about 30% down in Scotland. Winter rainfall in scattered eastern parts could peak at more than 30% above current levels, and is likely to fall in heavy bursts.
With this reduced rainfall levels, England would have to pipe water in, perhaps down from Scotland.
A map by scientists from the International Centre for Research on the Environment and Development in Nogent-sur-Marne, France, and the University of Bremen, created a map, replotting the position of 12 European capitals based on their projected climate futures. Whilst Oslo and Stockholm are both predicted to have Spanish climates, the prediction for Helsinki is more that of a mid-European city like Prague.
As BldgBlog points out, the architecture of northern cities like Helsinki will have to change gradually as it acclimatises to the new temperature and rainfall patterns.
