Global Warming Trend Without the Contributions

Question: Descrbe about the Global Warming Trend Without the Contributions? Answer: Using of Meteorological Data of Arctic Region It has been observed that there is a noteworthy seasonality in the climate of the Arctic region like some of the great rivers of Russia and North America almost stops its flow in the winter season. Besides, in the May, it can be seen that the frozen ice in the rivers starts to break gradually and in the month of June hurried downpour of fresh water can be observed (Banerjee, 2012). This is sometimes followed by the fall in flow and this process continues up to November as in November it stars to freeze. Figure 1.1: Yearly Cycle of Arctic Region Recording the Temparature of Arctic Region Name and General Location Date Temparature EUMETNET Arctic Ocean 3rd February, 2015 -24.0 C NPEO Station 5th February, 2015 -28.0 C IABP Station 7th February, 2015 -21.0 C UpTempO Station 9th February, 2015 -23.0 C Table 2.1 Arctic Temparature Data, February, 2015 It has been observed that the temparatre of Arctic Region has been recorded in the month of February, 2015 from the for different geostations. 3rd February, the tremparatre of this region was recorded as -24.0 C while from NPEO Station te temparatre was noted as -28.0 C. From IABP station, the temparatre was -21.0 C on 7th Febraary and on 9th Febrar te temparatre was recorded as -23.0 C. Terefore, it ca be said that the minimum teprature was recored on 5th Febrary from NPEO Station while maximum temparatre was noted on 7th Febrary from IABP station (Mahlstein and Knutti, 2012). Elaboration of Data received from the Stations Here the temparatre has been recorded in the month of February. In this time, Sun is in the southern part of the world and thus in northern part it is winter solistice. In this time peroid, the Arctic region faces 24 hours of night. Chilling weather accompanied by thunder storm can be observed and this is the most common scenarion of this time period (Nagato and Tanaka, 2012). At this point of time, the Sun sheds its maximum heat in the south region and this affects the weather of Arctic in such a way that most of the time heavy thunder storm make the situation worst. As we all know the Equinoxes are on 22nd September and 20th March, therefore, the temparature statrs to rise in the month of February comparaed to the other winter months of the year. In the first part of February, the temparature tends to be low but at the end of this month, the temparature starts to rise gradually as the Equinox comes close that is in March (Perry and Andersen, 2012). Comparing the Temparature of Arctic Region in normal time and in the specified year In this report, the reseracher has selected the month of February, 2015 and has compared this data with data received from 2010, February (Showstack, 2012). Here the weather data of February, 2010 has been given for the better evaluation of the data. Name and General Location Date Temparature Eumetnet Arctic Ocean 3rd February, 2010 -24.0 C NPEO Station 5th February, 2010 -30.0 C IABP Station 7th February, 2010 -22.0 C UpTempO Station 9th February, 2010 -19.0 C Table 4.1: Arctic Temparature Data, February, 2010 It can be seen from the above table that the temparature of these stations in the year 2010 was recorded and this has differed from the temparature recorded in the month of February of 2015. the lowest temparature has been recorded as -30.0 C in NPEO station on 5th February and the highest temparature was recorded -19.0 C on 9th February, 2015 in UpTempO Station. Therefore, from the noted data it can be said that for the last 5 years the trend of temparature has changed and this is perhaps due to the global warming (Roberts, 2012). Comparing the Observed data Arctic Climate Impact Assessment focuses on the four regions of Arctic regions and this is considered as the first comprehensive as well as integrated assessment of the climatic change along with the ultra violet radiation throughout the whole arctic region (Showstack, 2012). It has been noted that middling sea ice extent for August 2015 was recorded as 5.61 million square kilometers. The rapid change of weather has been notoced here as many geographers argue that Antartic and Arctic are two vulnarable places of the world. It can be said that there is a large rate of daily ice loss since late July of 2015 and this has slowed down in August (Roberts, 2012). The ice is presently tracking poorer than the two standard deviations underneath the 1981 to 2010 long term standard. References Banerjee, S. (2012). Arctic voices. New York: Seven Stories Press.
