NOAA: 2012 Hottest Year On Record for U.S.
2012年：有记录以来最热的一年

Last year saw the warmest average temperatures on record—at least for the contiguous United States, according to a report released last week by the National Oceanic and Atmospheric Administration (NOAA). The average temperature was 13°C, compared with a 20th century average of 11.2°C. (The previous record-holder, 1998, saw average temperatures of 12.4°C). The year consisted of “a record warm spring, the second warmest summer, the fourth warmest winter, and a warmer than average autumn,” said climate scientist Jake Crouch, of NOAA’s National Climatic Data Center, in a press conference on 8 January. The data do not address global temperatures, however.

国家海洋和大气管理局（NOAA）上周发布的一份报告显示，去年是有记录以来平均气温最高的一年----至少在美国大陆地区是这样。平均气温13°C，相比而言整个20世纪的平均气温只有11.2°C（之前最高平均温是1998年的12.4°C）。在1月8号的一次新闻发布会上，NOAA数据中心的科学家Jake Crouch说，“有记录以来最暖和的春天，第二炎热的夏天，第四暖和的秋天和高于平均气温的冬天”组成了去年的四个季节。

Meanwhile, a draft of another climate related report—the U.S. Global Change Research Program’s National Climate Assessment on the impact of global warming in the United States, released every 4 years— was published on 11 January.It points to stronger evidence that the climate is changing rapidly, and primarily as a result of human activities, including the burning of fossil fuels—and notes that there will be increasing impacts on crops and fresh water supplies. The report, written by a group of 240 scientists, will now undergo a 3-month period of public comment and review.

与此同时，另外一份与气候变化有关的草案于本月11号发布，该草案每4年发布一次，来自于美国全球变化研究计划中，致力于研究气候变暖对美国影响的国家气候评估项目。草案指出越来越强的证据显示气候正在快速变化，而且主要是因为人类活动引起，包括燃烧化石燃料。草案同时也告诉人们要注意气候变化对于农作物和淡水供应的影响越来越大。这份草案由240位科学家编写而成，然后会公示3个月征集评论和意见。
