大数据能遏制气候变化吗？

    全球森林观察

    会动的蓝色细线有的打着旋儿、有的像溪流一样流动，它们反映的是全球各地的风向。东南亚地区的橙色斑点反映了当地火灾，中国上空的红色阴影则反映了极差的空气质量。这张由全球森林观察制作的地图是一个追踪森林火灾的利器。自从90年代末以来，全球森林观察一直试图绘制全球森林地图以实时定位毁林开荒行为。但当时要发布这样的报告可能需要三到五年时间。去年二月，全球森林观察推出了一款基于卫星数据追踪森林变化的地图。该地图不仅提供了全球的森林火灾信息，同时还能追踪地球表面的森林总量。目前全球约有50万人在使用该服务，其中包括印度尼西亚政府，以及雀巢和联合利华等大企业。

    Global Forest Watch

    Animated thin blue lines swirl in eddies and rivulets to show which way the wind is blowing around the globe. Orange dots point out fires in Southeast Asia while a thick haze of red boxes highlight poor air over China. This map is a tool designed by Global Forrest Watch to help track down illegal forest fires. Since the late ‘90s Global Forest Watch has been trying to map the world’s forests and provide up-to-date information on where deforestation occurred. However it would take at least three to five years to publish reports. Last February, Global Forest Watch launched a map that uses satellite data to track forest change. Not only does the map provide information on forest fires around the world, it also tracks the total amount of forest cover on earth. So far nearly half a million people all over the world use the service including the Indonesian government and major corporations like Nestle and Unilever.
