The effects of global warming have intensively observed in Mongolia in recent years as the average air temperature was increased by 2.2C over the last 70 years according to the weather observation data since 1940. 

The driest period was recorded between 1997 and 2001 due to very low amounts of precipitation and many hot days in summer where temperatures often exceed 30C. As a result, humidity went down rapidly to minus and the country has seen the driest period over the 70 years. 

In recent years, an average of 30 atmospheric incidents were observed each year from 1990 and 2000, whereas the number had doubled between 2001 and 2016. For instance, the number of days with dust storms went up to 47 in 2015 from 37 in 2014.

Although Mongolia’s total carbon dioxide emission is lower than the global average, 6.08 metric tons of COemission per capita indicates a number that is quite higher than the global average.

Climate change, pastoral degradation, and improper mining activities have speeded up the drying process of surface waters – springs, rivers, ponds and lakes. According to results of 2016 centralized census of surface water, a total of 774 springs, 263 small and large rivers and 346 lakes have dried out.

According to the climate change impacts assessment of environmental, social and economic sectors, the negative impact on the animal husbandry, agriculture, and forestry is likely to increase.
