on Monday, the UN said that the level of greenhouse gases in the atmosphere, which is the main driving force of climate change, reached a record high last year and called for immediate action to ensure "the future well-being of mankind."
"there are No signs of slowdown, not to mention the decrease in the concentration of greenhouse gases in the atmosphere, despite all the commitments under the Paris agreement on climate change," - said the head of the world Meteorological Organization (WMO) petteri Taalas.
basically an annual WMO Bulletin on greenhouse gases, WMO has been specified concentration of co2 in the atmosphere in 2018 at the level of 407,8 parts per million compared to of 405.5 parts per million (ppm) in 2017.
the increase was slightly above the average annual growth over the last decade.
According to scientists, carbon dioxide CO2 carriedet responsible for about two-thirds of the "heating" atmosphere Lands.
According to WMO, the second most common greenhouse gas in the atmosphere is methane, which is partly secreted from the waste of cattle and fermenting rice paddies, which is the cause of 17 percent of the warming.
the UN Agency reported that nitrous oxide, the third highest heat-generating substance that is a gas emitted mainly agricultural fertilizers, has caused about six percent of the warming on Earth.
According to the UN, atmospheric concentrations of methane and nitrous oxide reached record high last year.
"This ongoing long-term trend means that future generations will be faced with ever more serious consequences of climate change, including increasing temperatures, more extreme weather, water scarcity, and sea-level rise and disturbance of marine and terrestrial ecosystems," - said the WMO.
Emissions are the main factor determining the number of levels of greenhouse gases, but their levels of concentration are a measure of what remains after a series of complex interactions between the atmosphere, biosphere, lithosphere, cryosphere and oceans.
About 25 percent of all emissions currently are absorbed by the oceans and biosphere, which includes all the ecosystems on Earth.
the intergovernmental group of experts on climate change (IPCC) stated that to maintain the temperature below 1.5 degrees Celsius, the net emission of CO2 must be zero, that is, the amount pumped into the atmosphere must equal the amount being removed.
Although Taalas has made it clear that the world will not reach the UN goals, he put forward some reasons for cautious optimism.
"the Visibility of these issues is the most high (what it was) ever" - he told reporters in Geneva, noting that the private sector is increasingly investing in green technology.
Even in the United States, where the administration of President Donald trump this month began the process of formal withdrawal from the Paris agreement, "there are many positive things," said Taalas.
Although Washington may have abandoned its obligations under the Paris agreement, "we have a lot of cities and States that are moving in the right direction," he added.
"Personally, I am more hopeful than it was 10 years ago, but of course, we should speed up the process," said Taalas.
