Greenhouse gases suddenly skyrocketed
According to new data, the amount of CO2 in the atmosphere has increased dramatically, with the fastest speed in nearly 30 years.
>>>Greenhouse gas emissions hit new records
According to a study by the World Meteorological Organization (WMO), atmospheric CO 2 concentrations between 2012 and 2013 increased at the fastest rate since 1984. WMO's Annual Greenhouse Gas News shows honey The global average CO 2 level in the air reached 0.0396% in 2013, an increase of nearly 0.0003% over the previous year. The amount of CO2 in the atmosphere is now 142% of that of 1750, before the industrial revolution began.
The WMO newsletter did not measure the emissions from power plant smokestacks, but recorded data about the amount of gas warming the earth remaining in the atmosphere after complex interactions took place between the air, land and sea. According to statistics, about half of all emissions are absorbed by the sea, plants and living organisms.
Michel Jarraud, WMO's secretary general, said: 'The Greenhouse Gas News report shows that, instead of reducing, atmospheric CO 2 concentrations are increasing at the fastest rate in nearly 30 years. "
However, the global average temperature has not increased with this continuous increase in CO 2 , making many people claim that global warming has stopped.
Alaska fishermen call for help in ocean acidification
In response to these comments, Oksana Tarasova, head of atmospheric research at WMO, said: 'The climate system is not as simple as a straight line. It does not necessarily reflect the temperature in the atmosphere, but if we look at the profile of the temperature of the ocean, we will see the heat absorbed into the hearts of the oceans. "
The ability to absorb CO2 in the earth's biosphere decreases
The report also shows that, in 2013, the increase in CO2 was not only due to increased emissions but also due to reduced absorption of CO2 in the Earth's biosphere.
Scientists at WMO are very confused by this trend. The most recent phenomenon of the biosphere's ability to absorb CO2 is in 1998, when the burning of biomass (biomass) took place all over the world, along with the effects of phenomena. El Nino is on the biosphere.
Oksana Tarasova said that in 2013 there was no obvious impact on the biosphere, so this phenomenon was even more worrisome. They do not know whether this is only a temporary phenomenon or will become a permanent state of the biosphere. It is possible that the biosphere has reached the saturation limit, but there is no conclusion yet.
WMO data shows that between 1990 and 2013 there was a 34% increase in climate warming effects, because CO 2 and other gases such as methane and nitrous oxide can last for so long in the election. ozone.
Unmatched ocean acidity rate
For the first time, the newsletter provides data on ocean acidification due to CO 2 . According to WMO, the oceans daily absorb about 4kg of CO2 from every person on earth. They believe that the current acidification rate is unprecedented in the past 300 million years.
The above evidence suggests that an urgent and focused political action is needed to address the problem, such as a global climate treaty.
Under this situation, world political leaders will meet in New York on September 23 during a special summit called by UN Secretary-General Ban Ki-moon, to kick off move for the next negotiations to arrive at a new international agreement on climate change by the end of 2015.
