In 2018, the average concentrations of carbon dioxide, methane and nitrous oxide have increased and once again broke the previous records. The concentration of carbon dioxide has increased by 0.57 percent to 407,8 ppm volume fraction (ppm), reported in the annual report of the world meteorological organization (WMO).
Human activities in the last century has led to a relatively sharp and sustained increase in the concentration of greenhouse gases, which in turn leads to a rise in average global temperature and global climate change. Recently, scientists have proven anthropogenic contribution to climate change “with the standard five Sigma”. New WMO data collected from dozens of stations worldwide, show that in 2018, the concentration of carbon dioxide, methane and nitrous oxide N2O, a key (for the effect on the heat balance) long-lived greenhouse gases increased again.
