| 摘 要： | 2008年可能是自1850年开始有器测记录以来全球第10个最暖的年份，全球海面和陆面综合气温比1961-1990年的年平均高0.31℃，150 a来最热的10个年份都集中在最近12 a里，全球气候变暖的趋势仍在持续。北极的海冰面积在融化期降至自1979年卫星测量以来的第2个最低点；同时，2008年极端天气气候事件频发，世界许多地方出现了洪灾、持续性严重干旱、冰雪风暴、热浪和寒潮等；拉尼娜现象在2月份呈峰值状态，以后逐渐减弱至近中性状态；南极臭氧洞进一步增大。

| Abstract: | The year 2008 is likely to rank as the 10th warmest year on record since the beginning of the instrumental climate records in 1850. The global combined sea-surface and land-surface air temperature for 2008 is currently estimated at 0.31℃ above the 1961-1990 annual average of 14.00℃. Ten of the warmest years were all among the recent 12 years, indicating a continuous trend of global warming. Arctic sea ice extent during the 2008 melt season dropped to its second-lowest level since satellite measurements began in 1979. Climate extremes, including devastating floods, severe and persistent droughts, snow storms, heatwaves and cold waves, were recorded in many parts of the world. La Nina conditions gradually weakened from their peak strength in February, and near-neutral conditions prevailed during the later half of 2008. Antarctic ozone hole in 2008 is larger than that in 2007. |
