carbon dioxide accumulates as seas and forests struggle to absorb  -  carbon dioxide absorbent
Since its own records, carbon dioxide has accumulated fastest in the atmosphere, and as scientists warn, oceans and forests may have absorbed so much carbon dioxide, so much so that their key functions as "carbon sinks" are now seriously threatened.
The increase in atmospheric carbon dioxide is partly due to an increase in the world's burning carbon emissions
According to the latest report of the World Meteorological Organization, more fossil fuels have found that the concentration of carbon has increased by nearly three parts per million (ppm)
By 396ppm last year.
But it is vital that preliminary data in the report indicate that, this jump can also be attributed to "The reduction in the absorption of carbon dioxide by the Earth's biosphere"-this is the first time that the effectiveness of the world's largest carbon sink has been scientifically proven to be questioned
Scientists say they are confused and extremely worried about the prospect of reduced absorption of the world's oceans and plants, and they cannot explain this, which may accelerate constructionup of heat-
If this trend continues, greenhouse gases will be emitted into the atmosphere.
Professor Dave Reay of the University of Edinburgh said: "The continued surge in CO2 concentration last year is a source of concern . ".
"It is particularly worrying that carbon reserves in the world's forests and oceans may be weakening.
"So far, these" carbon sinks "have locked in almost half of the carbon dioxide we emit," added Professor Reay . ".
"If they start to fail with further warming, then our chances of avoiding dangerous climate change will become very slim.
"Plants and oceans absorb about human carbon dioxide emissions every year, and the other half enters the atmosphere, which can remain in the atmosphere for hundreds of years.
The last decline in the biosphere's ability to absorb carbon was in 1998, during which a large number of forest fires and dry weather killed many plants and hit the world's carbon sinks.
But Dr. Oksana Tarasova, head of the World Meteorological Organization's atmospheric research department, said this time it was even more worrying because there was no significant impact on the biosphere this year.
"The problem is very serious.
It may be that the biosphere has reached its limit, or it may be close to its limit.
Or, it just becomes less effective in absorbing carbon.
"But it's still very worrying," Dr. Tarasova said . ". The worst-
In the event that the carbon sink is completely operational, the rate at which carbon dioxide emissions accumulate in the atmosphere will double, significantly increasing the impact of climate change, such as storms, Dr Tarasova said, drought and rising temperatures.
According to the latest survey by the World Meteorological Organization, the ocean is currently becoming acidic at an unprecedented rate in the past 0. 3 billion years.
The report says this is because they absorb about 4 kg of carbon dioxide for everyone on Earth.
The findings of the World Meteorological Organization strengthen the call for cooperation
Global coordinated action to limit global warming to 2C will have increasingly serious consequences.
"We don't have much time.
Past, Present and future carbon dioxide emissions will have a cumulative impact on global warming and ocean acidification.
Law of physics-
The secretary of the World Meteorological Organization said
General Michelle Jarrod
He added that there is an urgent need for a decline in fossil fuels and other emissions, rather than an increase.
"We have the knowledge, we have the tools to act, to try to keep the temperature rise within 2C, to give our planet a chance to give our children and grandchildren a future.
"Pleading ignorance is no longer an excuse for not taking action," he said . ".
Total concentration of heat-
When methane and nitrous nitrogen were included in 2013, greenhouse gas catches jumped to a record 479ppm.
Anything that removes carbon dioxide is a carbon-absorbing device. CO2)
Stored from the atmosphere, in a process called carbon storage.
There are two major carbon sinks in the world-plants and oceans-which historically absorb about human carbon dioxide emissions from the atmosphere and store them.
The leaves absorb carbon dioxide during photosynthesis, and the energy of the sun is used to separate oxygen released back into the atmosphere and stored carbon.
Half of the trees are made of carbon.
The ocean absorbs carbon dioxide in the diffusion, which is basically to balance with the atmosphere.
Marine organisms then extract carbon and oxygen from the water and combine them with calcium to produce calcium carbonate.
