A surprising surge in C dioxide stage has propelled greenhouse gases to newfangled high in 2013 , according to the annualGreenhouse Gas Bulletinreleased this week by the World Meteorological Organization , which accumulate data from over a hundred monitoring stations around the world .
“ Far from precipitate , the concentration of atomic number 6 dioxide in the atmospheric state actually increased last year at the fastest charge per unit for nearly 30 age , ” WMO ’s Michel Jarraud say in anews button . At this charge per unit , the global annual average CO2concentration is set to sweep thesymbolic 400 parts per million thresholdby the next year or two .
Between 1990 and 2013 , there was a 34 percent increase in the warming effect on our mood due to long - survive greenhouse gas like CO2(which report for 80 percent of the increase ) , methane , and nitrous oxide . About 40 percent of methane and 60 pct of the nitrous oxide emissions occur from natural source like wetland and termites .
The amount of CO2 in the atmosphere in 2013 was 396.0 part per million – that ’s 142 percentage of preindustrial ( around 1750 ) grade . Methane also get through new highs with 1824 portion per billion , up 253 percentage . nitric oxide was 121 percentage of 18th - century levels with 325.9 parts per billion .
Levels of CO2increased more between 2012 and 2013 than any other year since 1984 . The jump of 2.9 parts per million was twice as large as the average increment in late ten . “ We are learn the growth rate rise up exponentially , ” WMO ’s Oksana Tarasovatells Washington Post . And according to preliminary information , that ’s because the steady increasing levels were made even worse by the rock-bottom CO2uptake by the Earth ’s biosphere , like our helpful plants and dirt .
The annual story focuses on atmospheric concentrations , not emissions : emission are released into the atmosphere , and concentrations tell you what stay on after all the interactions between the atmosphere , biosphere , and oceans have taken place . About a one-quarter of our total anthropogenic emission are taken up by the ocean , and another tail is hire up by the biosphere . This reduces the amount of CO2 in the ambiance , but that ’s also acidifying our oceans at an unprecedented rate : ocean take up about 4 kg of CO2per mean solar day per person .
“ atomic number 6 dioxide persist in the atmosphere for many hundreds of years and in the sea for even longer . Past , present and future CO2emissions will have a cumulative wallop on both global warming and ocean acidification,”Jarraud sum . “ The laws of natural philosophy are non - negotiable . ” Here are some sum-up graphs for CO2 , methane ( CH4 ) , and nitrous oxide ( N2O ):
