Plants Migrate Up the Alps
Plant species are migrating to higher
elevations in the Swiss and Austrian Alps, where temperatures have climbed
1.25° F this century. University of Vienna scientists collected data on
vascular plant species at high elevations in the middle Alps and compared the
modern data with detailed historical records from early in the century. They
concluded that "there is no doubt that even moderate warming induces
migration processes, and that this process is under way ... global warming is
already having a significant impact on plant ecology."
