A recent study reveals: the arctic has warmed a couple of degrees already causing extreme weather phenomena and the reindeer die

a New study sheds light on how the earth's polar regions are warming to the consequences of climate change and what that means. International multidisciplinary research was attended by 15 people from around the world, including the university of Lapland's Arctic centre.

according to the Study, the earth's northern polar region has warmed considerably faster than other regions on earth. Only in this decade, the Arctic's average temperature has risen by 0.75 degrees, when the size of the earth has had roughly the same amount of warming over 130 years.

the International climate change debate, often considered as a major limit on it, if the earth's average temperature will rise two degrees above pre-industrial levels. In the arctic regions of two degrees rise can be discussed already now, says university of California professor Eric's Post the research group bulletin.

– in the Arctic region, the two degree rise is already a reality in a few months a year. Throughout the year the average can reach the two-degree limit was already 25 years before the rest of the world.

Throughout the globe the two degree limit is expected to be broken in 40 years, but the schedule involves a lot of changing factors and uncertainties. Professor post's forecast, according to the two degree limit would be reached in the northern polar regions, respectively, in 2035.

Particularly strong warming of the displayed air temperature. The graph compares 70. the latitude of the north side of the two-meter height to measure the temperature in average over the whole measurement period of the average value. The 1960s was approximately one degree celsius of the measurement period below the average, in recent years, there have been a couple of degrees above average. Warming is already affecting the north

global warming have a large impact on the arctic and the Antarctic nature, traditional livelihoods, tundra vegetation and methane emissions, say university of Lapland Arctic centre's research professor Bruce Forbes release.

– Change is already visible in the arctic region. For example, extreme fluctuations in winter weather are caused enormous porokuolemia in Russia, when a frozen blanket of snow has prevented the reindeer from dietary intake. The reindeer die is caused in addition to the permafrost liberated anthrax.

the Study's authors say that global warming also affects the polar regions on the outside. Transcontinental jääpeitteiden melting to raise the sea level. In addition, extreme weather related risks, such as killing heat waves and forest fires are on the increase especially in the northern hemisphere.

It, what happens in the Arctic, also affects the rest of the world. The arctic strong warming and the melting of the ice affect the atmospheric jet stream in ways that pose long-lasting and more damaging extreme weather phenomena, said Pennsylvania state university professor Michael Mann the research group bulletin.

the study results were published Wednesday in Science Advances science publication.
