"Plants are flowering faster than scientists predicted in response to climate change, research in the United States showed on Wednesday, which could have devastating knock-on effects for food chains and ecosystems. Global warming is having a significant impact on hundreds of plant and animal species around the world, changing some breeding, migration and feeding patterns, scientists say."
