Melting glaciers could produce extensive new Pacific salmon habltat by 2100, study finds

摘要

A study led by Simon Fraser University researchers has found that the retreat of glaciers in the Pacific mountains of western North America could produce more than 6,000 kilometers of potential new Pacific salmon habitat by the year 2100.The researchers modeled glacier retreat under different climate change scenarios - essentially "peeling back the ice" from 46,000 glaciers between southern British Columbia and Southcentral Alaska - to look at how much potential salmon habitat would be created when the underlying bedrock is exposed and new streams flow over the landscape.
