渔业的发展机遇将需要极大的生态改革。
Arctic Frontiers, a conference organised at the University of Tromso in January, looked athow warming will change the ecology, to estimate whether it will bring one about.
今年一月,由特罗姆瑟大学主办的北极前沿会议上,讨论了全球变暖将会对北极生态产生的变化,以预测是否有利于渔业的发展。
The consensus was that it won tnot because the Arctic will change too little, but because itwill change too much.
达成的共识是不,不是因为北极几乎没什么变化,而是因为北极的变化太大。
Change and decay
改革和衰退
At first sight, this is counterintuitive.
乍看之下,这简直违背常理。
As the ice melts, more light can reach the water, and that means more photosynthesis bymarine algae.
当冰块融化时,水中将会有更多的光线,那就意味着海藻可能进行更多的光合作用。
In the past, algae began to grow under the ice sheet in May and continued to do so until lateSeptember.
过去,当五月来临时,冰下的海藻开始生长,整个生长期会持续到九月末。
Now, such growth starts in mid-March and continues until October.
