The content of CO2 in the atmosphere reached a critical level

Содержание CO2 в атмосфере достигло критического уровня

The critical level of CO2 was recorded at the station of Mauna Loa in Hawaii

Since 1850 the average temperature on the planet has risen by almost 1 degree.

The level of carbon dioxide in the atmosphere of our planet in 2015 for the first time during the observation period has reached a critical level of 400 parts per million, said the world meteorological organization (WMO). According to experts of the WMO, it is possible that the concentration of CO2 in the atmosphere now will not fall below this bar “over many generations”.

The critical level of carbon dioxide was recorded at the station of air sampling, located in Mauna Loa in Hawaii. In a statement released by the world meteorological organization report on greenhouse gases (Greenhouse Gas Bulletin) also noted a significant increase in atmospheric methane and nitrogen oxides.

Associated with anthropogenic factors of greenhouse gases in the atmosphere, according to WMO statistics, 2014-2015 remained at a relatively stable level. At the same time, a significant impact on the increase in the concentration of carbon dioxide in the atmosphere has had a climatic phenomenon El niño, scientists say.

Occurs in the Pacific ocean temperature anomaly known as El niño causes droughts and floods in different parts of the world. In particular, the most recent El niño resulted, as expected, to weaken monsoon rains in Southeast Asia, droughts in South Australia, the Philippines and in Ecuador, snow in USA, heat waves in Brazil and floods in Mexico.

Because of El niño has decreased the ability of tropical forests absorb from the atmosphere the carbon dioxide. The drought became the reason of occurrence of forest fires, which also affected the increase in the concentration of greenhouse gases.

As experts assume, the content of carbon dioxide in the atmosphere will not fall below 400 ppm (ppm) throughout 2016. According to meteorologists, the last time the level of CO2 in the Earth’s atmosphere regularly rise above 400 ppm in the period from three to five million years ago.

Since 1850 the average temperature on the planet has risen by almost 1 degree. Since the industrial revolution the level of carbon dioxide in the atmosphere has increased by 30%.

If the average temperature of the Earth’s atmosphere will rise by about 2 degrees compared to pre-industrial levels, as scientists say, this can lead to dangerous and unpredictable climate change.
