Temperature of Arctic
Although global warming is affecting the whole earth in recent decades, but only looking at the Arctic, it seems that the Arctic has to pay a huge price for its decadence. According to the records recorded by the Danish Meteorological Institute, at several places in the Arctic, the temperature has been found to be asymmetrical upto 20 degrees Celsius. In the review of the records, the average temperature of Arctic on November 19, 2013 has been found to be around 7.3 degrees Celsius more than the temperature of 1979-2000. Statistics also show that in October 2016, Arctic ice expansion was 28.5 percent below the average, which is by far the lowest.
Powerful winds in the Arctic region are considered partly responsible for the decreasing snow expansion in November-2013. In the Arctic region, on November 17, 2016, there were strong winds at speeds up to 90 kilometers per hour. In the month of December 2015, the cyclonic storms in the Arctic brought a lot of heat and humidity by bringing dryness to the atmosphere, due to which the Arctic ice shrank instead of being thick and strong. The impact of shrinkage in snowflake was seen from Florida to the Barents and Kara seas till January 2017. A similar cyclonic storm hit again once again on November 14, 2016 in the Central Arctic, with effect from November 2016 on the entire Arctic.
Hot water in the arctic ocean
Apart from this, it is also believed to be the reason that warm water is reaching the Arctic Ocean. In fact, during the northern summers of 2016, offshore warm waters of North America were pushed by the Coriolis force to the Arctic Ocean. Although this hot water took several months to run alongside the Gulf Stream via the North Atlantic, but possibly this hot water is now absorbed in the Arctic Ocean. According to the report, this hot water reached Svalbard in the Arctic Ocean for the first time on October 31, 2016, and the temperature went up to 17 degree Celsius, which was much higher than the average of 13.9 degrees Celsius for the thirty years between 1981 and 2011.
Snow free arctic
According to the NSIDC, ice in the Arctic area of approximately 11.11 million square kilometers was melting rapidly since the year 2016. Ice melting speed was the highest in the year 2016, due to which the snow melted from approximately 12.7 lakh square kilometers.
An approximate graph has been prepared based on the statistics obtained by Tortine Vidal in the Arctic Sea Ice Collapse blog, which states that if Arctic ice melts with this rapidness, then by the year 2024, the free-form Arctic will start. According to different test estimates, most of the Arctic ice will be completely destroyed, or most of its volume will be destroyed from September 2040 to some time after 2100.
The clouds of the unforeseen consequences of global warming on the Arctic
During the ‘Polar Night‘ in the North Pole in the last December-January, when there was a complete night time, the Arctic had to be very cold and should have covered the thick coat of sea ice. But that has not happened. Arctic scientists have warned that due to melting of Arctic icebergs, frightening results can be seen on 19 snow peaks across the globe.
In the climate change conference in Morocco in November 2013, the United Nations World Meteorological Institute (WMO) has released its report saying that the data of five years from 2011 to 2015 has made it clear that 2016 was the warmest year And the example of record heat in Russia is also given in this report with special mention. Similarly, Arctic Council’s Arctic Resilience Report has warned against the impact of Arctic heating in the near future on the Indian Ocean, and due to the change in the natural nature of this region, it is extremely difficult to control climate change globally. Will be done.
Due to global warming in the Arctic Council report, the main effects of the arctic area’s creatures, planters, fishes, marine mammals, birds, hotspots, vegetation and humans have also been mentioned in detail, which is definitely worrisome. is. The deep-colored vegetation of the Arctic tundra region, which is becoming snowless, is absorbing more heat after the increase in temperature, while on the other hand due to changes in ice distribution the oceans are also warming and the effects of change in climate trends Are affecting the monsoon till Asia. Similarly, with the decline in important Arctic fisheries, sea ecosystems around the world have also been subject to odd effects.
If the rise of temperature reaches its peak, then the Antarctic ice will also melt along with the Arctic and the sea level will rise. This will eliminate many species. It is estimated that 20 million out of one million species will end forever. According to the biological history of the Earth, in the last 50 million years it has happened five times on earth that most organisms of the Earth have become extinct. Due to global warming, perhaps the sixth time the life threatening life from Earth is beginning to threaten extinction.
