近日，世界气象组织（WMO）发布的最新一期《温室气体公报》（以下简称《公报》）指出，2021年，大气中二氧化碳、一氧化二氮和甲烷浓度均创新高，并在2022年继续上升，其中甲烷浓度增幅最大。WMO自2006年起每年发布一份《公报》。
WMO的研究人员在全球100多个监测点测量了大气中主要温室气体的浓度。他们发现，自1750年以来，二氧化碳对全球变暖的贡献率约为66%，其浓度在2021年平均增加了2.5ppm，达415.5ppm。一氧化二氮对全球变暖的贡献率约为7%，增加了1.3ppb，达334.5ppb。这些增幅都略高于前10年的年均增幅。

Recently, the latest issue of the Greenhouse Gas Bulletin (hereinafter referred to as the Bulletin) issued by the World Meteorological Organization (WMO) pointed out that in 2021, the concentration of carbon dioxide, Nitrous oxide and methane in the atmosphere reached a new high, and continued to rise in 2022, with the largest increase in methane concentration. Since 2006, WMO has issued an annual "Gazette".
WMO researchers have measured the concentrations of major greenhouse gases in the atmosphere at over 100 monitoring points worldwide. They found that since 1750, the contribution rate of carbon dioxide to global warming has been about 66%, and its concentration has increased by an average of 2.5 ppm in 2021, reaching 415.5 ppm. The contribution rate of Nitrous oxide to global warming is about 7%, increasing by 1.3 ppb to 334.5 ppb. These increases are slightly higher than the average annual growth rate of the previous 10 years.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced a valve switching system for gas chromatography, which can separate the content of three greenhouse gases: methane, carbon dioxide, and nitrous oxide in one injection. The separation is good, and the analysis time is short. EPC gas path or fully automatic injection system can be selected according to customer requirements.
