2012年美国天气记录被打破超过3500次

交互式地图显示极端气温、降雨、降雪、洪水、野火和干旱

加入我们的科学爱好者社区!

过去两周的新闻报道指出,2012年是美国有记录以来最温暖的年份。今天我们了解到,根据自然资源保护委员会 (NRDC) 的数据,2012年打破了3527项月度天气记录。这个数字超过了2011年创下的3251项记录,之前的最高纪录。NRDC刚刚发布了一个交互式地图,该地图配备了一个滑块,可以从一月移动到十二月,以显示在任何给定日期发生创纪录的温度、降雨、降雪、洪水、干旱和野火的地点。

地图网站上的表格还列出了具体的日期、地点和天气记录。Kim Knowlton,NRDC的资深科学家,在一份准备好的声明中指出,极端天气的发生率上升“已经唤醒了全国各地的社区,使其意识到准备和保护的必要性。”

田纳西州和威斯康星州在记录到新高温记录的报告站比例最高的州中领先,分别为 36% 和 31%。2012年3月是有记录以来美国本土最热的3月,7月是有记录以来最热的单月。去年夏天还在美国中部地区造成了50年来最严重的干旱;29个州的1300个县宣布为干旱灾区。全国范围内的野火燃烧面积超过 370 万公顷;平均火灾面积为 65 公顷,远远超过 2001-2010 年的平均水平 35 公顷。

NRDC表示,极端天气记录的上升应促使州和国家层面努力遏制二氧化碳排放(气候变化的驱动因素)并提高能源效率,并应促使州和地方政府制定全面的应急管理计划。
