400ppm CO2: Man blames El Niño ...
The impact of the phenomenon, translated into the severe droughts that hit large tropical areas, reduced the capacity of the forests to absorb CO2, which is why they point to El Niño as the culprit of maintaining these high rates.
We have entered the index of 400 parts per million (ppm) of CO2 in the air, which is the main gas that catapults the so-called greenhouse effect, which means the highest figure in the history of mankind.
CO2 is the main responsible for global warming, which in turn is responsible for the irreversible climate change that we are witnessing. The serious thing is that once this gas is released, it will take thousands of years to lower these concentration indexes.
The experts set their sights on the weather phenomenon of El Niño as the cause of maintaining such high rates, because of its impact on climate changes that affect the rainforest.
By way of illustration and in comparative terms, at the beginning of the Industrial Revolution there was 278ppm of CO2 in the air. It was a concentration that represented a natural balance between the atmosphere, the oceans and the biosphere, but the development of human production in an industrial way, based on the energy achieved by burning fossil fuels, first coal and now oil, altered that balance .
It was the US agency National Oceanic and Atmospheric Administration NOAA, with the instruments it has in the Hawaiian observatory of Mauna Loa, who captured in 2013 for the first time this unprecedented concentration of carbon dioxide in the air.
The registry, however, was punctual and cataloged as very localized and temporary, and in the following observations that were developed this figure fell, remaining at high indexes, but under the 400ppm. At 2015, according to the World Meteorological Organization, OMM, the 400ppm brand of CO2 became a widespread and global reality.
For professionals of NOAA, the straw that has filled the glass has been the climatic phenomenon of El Niño, which had its maximum intensity in the middle of the 2015. They explain that the impact of the phenomenon, translated into the severe droughts that hit large tropical areas, reduced the capacity of the forests to absorb CO2, so they point to El Niño as the culprit of maintaining these high rates, although El Niño It has already passed and the number of 400ppm remains unchanged, showing that the high accumulation of CO2 in the air is the responsibility of the action of man and not of El Niño.
In conversation with El País of Spain, the Secretary General of the WMO, Petteri Taalas, declares that "the 2015 year marked the beginning of a new era of optimism and climate action with the Paris agreement on climate change. But it will also make history by marking a new era of global warming with the reality of this record in the concentration of greenhouse gases“, he laments, and questions whether the objectives of COP21, which set out to prevent the temperature from rising more than two degrees by the end of the century, can be met with such a high concentration of CO2. “The real problem is carbon dioxide, which remains in the atmosphere for millennia and even more in the oceans. If we do not stop the CO2 emissions, we can not fight against Climate Change or keep the rise in temperature below two degrees compared to the pre-industrial era“, he maintains in the interview.
