Global warming is chasing plants and animals, forcing them to head uphill or north to find suitable habitat. Scientists have considered migration corridors — restored, healthy natural areas that connect current habitats with likely landing spots — as a way to help plants and animals stay a step ahead of climate change. New findings published on … Read More
