12月22日3时22分,中国在酒泉卫星发射中心成功发射全球二氧化碳监测科学实验卫星。相关专家表示,这颗碳卫星将使中国初步形成针对重点地区乃至全球的大气二氧化碳浓度监测能力。联合国政府间气候变化专门委员会在2007年发布第四次评估报告称,由于人类活动影响,主要温室气体二氧化碳和甲烷的浓度已经上升到2500万年以来的最高值,并且呈上升趋势。精确监视全球二氧化碳的排放状况,才能有效开展气候变化研究。碳卫星工程副总指挥、中科院国家空间科学中心副主任龚建村说,此次发射的是中国首颗用 At 22:22 on December 22, China successfully launched the global carbon dioxide monitoring scientific experimental satellite at the Jiuquan Satellite Launch Center. Relevant experts said the carbon satellite will enable China to initially form an atmosphere of carbon dioxide concentration monitoring capabilities for key areas and even the world. In its fourth assessment report released by the United Nations Intergovernmental Panel on Climate Change in 2007, the concentrations of carbon dioxide and methane, the major greenhouse gases, have risen to their highest level in 25 million years due to human activities and are on the rise. Accurately monitor the global carbon dioxide emissions in order to effectively carry out climate change research. Deputy Chief of Carbon and Satellite Engineering, Gong Jiancun, deputy director of the National Space Science Center of the Chinese Academy of Sciences, said that this launch is the first in China
