Climate change doubles tundra plant life, boosting shrubs, grasses

The Canadian Press (Bob Weber) – Climate change is already having a dramatic effect on plants in the High Arctic, turning the once rocky tundra a deep shade of green and creating what could be another mechanism speeding up global warming. In a new study to be published in the November issue of the journal Ecology, University of British Columbia geographer Greg Henry has, for the first time, confirmed that rapidly rising temperatures in the Arctic are creating major changes in the plants that live there … Henry says the total amount of plant material above the ground has doubled. In wetlands, that mass is at least three times what it was in the early 1980s. Plants that barely reached researchers’ ankles now tickle their shins.
