应对全球变暖:为所有国家提供预报
International agencies are coming together to provide climate forecasting to countries without it, particularly because they may be hardest hit. 很多国际机构目前正一起为不能获得气候预报的国家提供这方面的服务,尤其是那些可能受到气候变化严重影响的国家。
Climate Forecasts for All
Global warming could transform large swaths of Africa: shifting rains, spreading malaria and other insect borne diseases, even changing the size of the Sahara Desert.
Yet, the bulk of the world's climate forecasting has been concentrated on those regions that host the supercomputers that can do it: the U.S., Europe and the rest of the developed world.
That's set to change. Meeting for just the third time since 1979, the World Climate Conference established a framework last week for extending science-based climate predictions to all. Think the weather forecast, only larger.
This conference is famous for, among other things, creating the International Panel on Climate Change, whose reports have warned the world of accelerating climate change. The goal of this new framework is to better enable all countries to adapt to that future climate.
To that end, it calls for expanded observations of the global climate, public access to climate data, more climate prediction research and a new Climate Services Information System. This will provide local governments with expected changes to water resources, agriculture, fisheries, forests, even health.
Of course, climate predictions will also guide adaptation to a warmer globe, and even potentially provide early warnings for natural disasters. But they won't be perfect. As Robert Heinlein said, climate is what you expect, weather is what you get.
为所有国家提供气候预报
全球变暖可能会改变非洲的大片土地:使雨带转移,使疟疾和其它由昆虫传染的疾病四处扩散,甚至能改变撒哈拉沙漠的大小。
但是,世界上气候预报的大部分都集中在那些拥有超级计算机的地区(美国、欧洲以及其它发达国家)。气候预报服务就是由这些超级计算机提供的。
这种状况肯定是要改变的。自从1979年以来,世界气候会议(World Climate Conference)才召开了三次,为了让科学的气候预报扩展到所有的国家,世界气候会议上周为此确立了一个框架协议。以后想到天气预报,其预报范围可能要大一些了。
除了其它一些事情外,世界气候会议出名在于创立了国际气候变化委员会(International Panel on Climate Change),这个委员会对全球气候加速提出了警告。这个新框架协议的目标在于让所有国家都能更好地适应未来的气候。
为了达到这个目标,它呼吁扩大对全球气候的观测、让公众能使用气候数据、展开更多的气候预测研究,以及建立一个新的气候服务信息系统(Climate Services Information System)。这将为地方政府提供有关水资源、农业、渔业甚至健康的有关预期变化信息。
当然,气候预测也将就如何适应地球的气温升高提供指导,甚至还有可能提供有关自然灾害的早期预警。但是,这些不会很完美。正如Robert Heinlein所说,你预测的是气候,而你经历的是天气。 |
