<\/p>\n

World meteorological organization<\/a> released its annual Greenhouse Gas Bulletin<\/a> this\u00a0week, presenting the state of greenhouse gases in the atmosphere in 2015.\u00a0It shows that the concentrations of\u00a0\u00a0CO2 \u00a0<\/sub>are above 400 parts per million on average across the globe.<\/p>\n

One of the things that pushed the greenhouse gas release over the edge is El Nino, the natural climatic event that occurs every 2-7 years and alters climatic cycles on the planet. But even though El Nino is over, the effects of it will linger on, because the anthropogenic release is not decreasing.\u00a0\u00a0Concentrations of CO2\u00a0<\/sub>will probably not fall below that 400 ppm mark for generations, according to MIT Technology Review<\/a>.<\/p>\n

Similar increase\u00a0is reported for methane release. Methane release has been increasing steadily since 2007, and reached a new high in 2015 (some 1845 parts per billion). Studies indicate that increased methane emissions from the wetlands in the tropics and anthropogenic sources at mid-latitudes of the northern hemisphere are likely causes for the increase. 40 percent of global methane release is believed to come from natural sources such as wetlands. The rest comes from human activities, such as agriculture and industry.<\/p>\n

Norwegian measurements may be higher<\/h2>\n

Cathrine Lund Myhre is a senior scientists at Norwegian Institute\u00a0for Air Research (NILU), \u00a0and project manager\u00a0for MOCA project i<\/a>n which\u00a0\u00a0CAGE is a partner. She is worried about the development reported by WMO. NILU collects atmospheric measurements of greenhouse gases from, among others,\u00a0its Zeppelin observatory\u00a0<\/a>on the Arctic archipelago Svalbard. Zeppelin has been collecting greenhouse gas measurements \u00a0since 2001, and its remote location far away from contaminants, makes the station unique for surveillance of global trends. New measurements\u00a0from NILU observatories are being sent to the Norwegian Environment Agency\u00a0 next week, and according to Lund Myhre may be higher than those reported by WMO.<\/p>\n

“It will be interesting to see the results of our measurements compared to those published by WMO” she says\u00a0in a press release from NILU<\/a>. “Normally our measurements are slightly higher than the global average values, \u200b\u200bsince the anthropogenic sources of release mainly are found in the Northern hemisphere”\u00a0<\/span><\/p>\n
