According to the UN experts, the concentration of greenhouse gases in the Earth’s atmosphere has reached a new maximum level, breaking the previous records at year-end 2014, reports citing the World Meteorological Organization (WMO) in Geneva, with reference to DW.

According to experts, the amount of such gases as carbon dioxide, methane and nitrogen monoxide has increased by 36% from 1990 to 2014.

It is noted that industry and agriculture are among other sources of hazardous gases emissions in atmosphere. The concentration of carbon dioxide exceeded 400 parts per million in the spring of 2015, according to experts.

The representatives of the WMO are expected to demand a substantial reduce of greenhouse gas emissions of anthropogenic origin at the Paris Climate Conference to be held from November 30 to December 11, 2015.
