中文注释:水位的下降使大湖区的圣克莱尔河上暴露出一个狭长的沙岛。五大湖区,包括与之相连的河流、水道和较小的湖泊,占据了全球地表五分之一的淡水。但因为低于平均值的降水量,高温引起的高蒸发量,以及不断上升的用水量,导致这里的水位达到最低纪录。 文字来源于《几近干涸:急剧缩小的五大湖》(国家地理杂志,2002年9月),照片为该文所摄但未刊发。 作者: Jay Dickman
圣克莱尔河 密歇根 安大略 图片故事:高清壁纸:英文注释:St. Clair River, Michigan or Ontario, 2002Falling water levels expose a sandbar in the Great Lakes' St. Clair River. The five Great Lakes, and the rivers, channels, and lesser lakes that connect to them, hold a fifth of the world's surface fresh water. But below-average precipitation, increased evaporation due to above-average temperatures, and mounting water consumption is driving water levels here to record lows.
