Snow doesn’t melt in Himalaya
Himalaya is the world’s largest mountain range and includes the highest mountains in the world also. Scientists believed that in Himalaya, like north and south poles, the snow melts more and more and this quantity calculated around 50 billion tones of water per year. But a study came to surprise their results because it shows that mountains in Himalaya kept their level of ice for the last 10 years.
The new study worked with the elements that two satellites gave, called Grace, which analyze small changes in the Earth’s gravitational pull. When ice melts, the gravitational pull becomes weaker and is examined by the satellites that turned around earth. Grace began in 2002 and continues to examine the planet, but its mechanical system is close to an end. A new trip has been announced by USA and German space agencies and maybe will start in 2016.
The study checked all the areas in the world with the largest icecaps and glaciers and achieved due to the analysis of satellite data. The scientists found that in Himalaya and in north and south poles the process of melting ice is much limited than believed before.
Himalayas had the least levels of ice loss together with the other high mountains of Asia. The reason that this study shown these results and all the current and previous studies shown different ones, is because of the subjectivity in which both studies were campaigned. All studies till now analyzed the glaciers at lower latitudes and not those at higher ones. Glaciers at lower latitudes melt much more than glaciers at higher latitudes anyway and as result seemed that glaciers number become less and less in higher rhythms. Those glaciers at lower latitudes are much more appropriate for scientists to have access to them and as result more times analyzed, but because of the highest temperature at lower latitudes those glaciers lost more ice.
