Английская Википедия:Climate of the Nordic countries
The climate of the Nordic countries is that of a region in Northern Europe that consists of Denmark, Finland, Iceland, Norway and Sweden and their associated territories, which include the Faroe Islands, Greenland and Åland. Stockholm, Sweden has on average the warmest summer of the Nordic capitals, with an average maximum temperature of Шаблон:Convert in July; Copenhagen, Oslo and Helsinki[1] have an average July maximum temperature of Шаблон:Convert.
Seasonal conditions
Winter
In Denmark, January temperatures average between Шаблон:Convert and Шаблон:Convert.[2] Denmark's coldest month, however, is February, when the mean temperature is Шаблон:Convert.[3] The number of hours of sunlight per day does increase during the month of February for Denmark, where they get seven to eight hours a day.[4] Iceland winters are generally mild considering how high its latitude is. The coastal lowlands of Iceland have average January temperatures of about Шаблон:Convert, while the highlands of central Iceland generally stay below Шаблон:Convert. The lowest winter temperatures in Iceland are usually somewhere between Шаблон:Convert and Шаблон:Convert, although the lowest temperature ever recorded on Iceland was Шаблон:Convert.[5] In Norway, the coastal regions have mild winters, while further inland winter is much colder. During midwinter, southern areas of Norway only get five to six hours of sunlight a day, while the north gets little to none.[6] In January, the average temperature in Norway is somewhere in between Шаблон:Convert and Шаблон:Convert.[2] Like neighboring Norway, Finland averages Шаблон:Convert to Шаблон:Convert in the month of January.[2] Finnish areas north of the Arctic Circle rarely see the sun rise, due to the natural phenomenon of the polar night.[7] In January and February, temperatures in this area can drop to Шаблон:Convert.[2] In February, Northern Finland sees about four to six hours of daylight a day.[4]
Spring
In Iceland, spring brings warmer and milder temperatures. In the month of May, the average temperature is somewhere between Шаблон:Convert and Шаблон:Convert.[8]
Summer
Denmark's warmest month is July, when the mean temperature is Шаблон:Convert.[3] In Iceland, occasionally thunderstorms occur in the south in late summertime, due to warm air being deflected to northern latitudes from warm air masses in other parts of Europe. Also, cold air originating from Canada, warms rapidly over the ocean, forming thunderclouds. Thunderstorms, however, are very rare in Iceland, and there are less than five of them per year.[5] In June, Iceland's average daily temperatures range from Шаблон:Convert to Шаблон:Convert.[9] Summer conditions vary in Norway depending on location. The Norwegian coast has cooler summers than areas further inland. Due to its northern location, there is almost no darkness in June and July in the north, reaching as far south as Trondheim.[6] In summer, the average temperature in the Northern areas are somewhere between Шаблон:Convert and Шаблон:Convert, while further South it is usually Шаблон:Convert to Шаблон:Convert.[9][10] In Finland, summers experience more rainfall than other seasons. Finland areas north of the Arctic Circle rarely see the sun set during the months of June and July, due to the natural phenomenon Midnight sun.[7] Northern parts of Finland have summer temperatures in the Шаблон:Convert to Шаблон:Convert range, while further south, the temperature is closer to Шаблон:Convert and Шаблон:Convert.[9][10] During summer in Greenland, ice sheets breaking up trigger what is known as "glacial motion" or "glacial earthquakes".[11]
Global warming
Effects
Шаблон:Main Greenland is one of the areas in both the Nordic region and the world most affected by climate change. A July 2006 study completed by "The Journal of Climate", determined that the melting of Greenland's ice sheets was the single largest contributor to global sea level rise.[11] The temperatures from the year 2000 to the present have caused several very large glaciers that had long been stable, to begin to melt away. Three glaciers that have been researched: Jakobshavn Isbræ, Helheim and Kangerdlugssuaq Glaciers, jointly drain more than 16% of the Greenland Ice Sheet. Satellite images and aerial photographs from the 1950s and 1970s show that the front of the glacier had remained in the same place for decades. In 2001, the ice sheet began retreating rapidly, retreating Шаблон:Convert between 2001 and 2005. It has also accelerated from Шаблон:Convert to Шаблон:Convert a day.[12] Western Greenland's Jakobshavn Isbræ is generally considered the fastest moving glacier in the world, and has been moving continuously at speeds of over Шаблон:Convert a day with a stable terminus since at least 1950. The glacier's ice tongue began to break apart in 2000, leading to almost complete disintegration in 2003, while the retreat rate doubled to over Шаблон:Convert per day.[13] In the summer of 2005, the island of Uunartoq Qeqertoq was discovered off the eastern central coast of Greenland. Prior to 2005, many people assumed that Uunartoq Qeqertoq was actually a peninsula off Liverpool Land, however, the melting ice shelves revealed that it was only connected to the mainland by glacial ice.[14]
Predicted effects
Scientists estimate that should the current rate of climate change continue, Greenland's ice sheet, which contains Шаблон:Convert of ice, could melt and cause global sea level to rise by Шаблон:Convert. Some climate experts have estimated that Greenland could be losing Шаблон:Convert of ice each year.[11]
The 2008 Environmental Performance Index ranked countries based on the environmental performance of the country's policies. On the list, Norway was ranked 2nd, Sweden was 3rd, 4th was Finland, Iceland was ranked as 11th, and Denmark came in 26th.[15]
