The levels of carbon dioxide (CO2) in the atmosphere reached a historical peak in 2014, which contributes to the climate change and puts in danger the life of future generations on the planet, warned the World Meteorological Organization (WMO).
CO2, one of the main gas greenhouse (of which contribute to increase of temperature of the atmosphere), it reached the level of 400 parts per million (ppm) at the beginning of 2015 in the northern hemisphere, while its average was 397.7 ppm in 2014. These levels reach a new record each year since he took reliable records in 1984.
“It means the highs, extreme weather events, such as heat waves, flooding, melting of ice, rise in sea level and the acidity of the oceans,” explained Michel Jarraud, secretary-general of the WMO. “Soon 400 ppm will be a permanent reality,” he warned.
Concentrations of carbon dioxide are being amplified by higher levels of water vapor, which in turn have increased due to emissions of CO2. At the same time, the other two major gas greenhouse of human origin, methane and nitrous oxide, arrived in 2014 to thousand 833 parts per billion (ppb) and 327.1 has ppb, respectively.
Gas is odorless, colorless and toxic, CO2 to be sucked quickly combines with the hemoglobin in the blood and reduces the capacity of transport of oxygen to the lungs and cells of the body.
effects of CO2 in the health are breathing problems, headache, heart rate abnormal, low blood pressure, fainting, convulsions, and death in severe cases of poisoning by carbon dioxide. While the effects of higher temperatures include aggravation of cardiovascular diseases, respiratory, and those transmitted by vectors (such as malaria in mosquitoes).
Jarraud called to reduce the greenhouse gas emissions, which mainly come from burning fuels, agriculture, cement production and deforestation.
it Is expected that these issues be addressed at the end of this month in France during the negotiations of the United Nations Organization (UN) for a new climate agreement, in which will participate more than 150 countries (led by the largest producers of greenhouse gases: China and the united States).
