Cool spring is a consequence of climate changes, scientists point out

2013 - 03 - 29

Fresh snow and temperatures below zero. The first spring days in many European countries look like that. The unusually cold beginning of spring is, in fact, one of the consequences of climate changes according to climatologists.

Although global temperatures have been growing for over a long period, weather oscillations can cause, according to scientists, cooling down in some parts of the world. As it has been happening in Europe recently. The cause are the dramatic changes happening in the Arctic in recent years. They were accompanied with a record loss of ice cover at the North Pole last year. There is of 80 per cent less of sea ice there than 30 years ago.

These processes weaken the mechanism which influences the climate in this area. In vast areas of the Arctic, where in the train of sea surface uncovering the glacier is disappearing and there is appearing much darker sea surface which much less reflects sunrays, and so the warming is getting still faster.

According to climatologists, this is what influences significantly the weather in Europe. A slightly warmed up Arctic, actually, ceases pulling warm ocean and atmospheric currents and streams from the equatorial area which warm strongly the climate in Europe.

The weather oscillations caused by climate changes also disrupt strong air flowing in the atmosphere from the west to the east, which, under normal circumstances, separates the mass of cool air in the Arctic from temperate zone areas. Climate changes lead to decay of this wind barrier and cool air penetrates like that into Europe and other areas.

“A cool spring in Europe has reminded that climate changes can have much more complicated consequences than one would expect. In many parts of Europe it is freezing now because the world is getting warmer and the weather is becoming less predictable,“ stated Dalibor Dostal, the director of the European Wildlife conservation organization.
