"Plant Study Flags Dangers Of Warming World"

"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."

"Increased carbon dioxide concentration in the atmosphere from burning fossil fuels can affect how plants produce oxygen, while higher temperatures and variable rainfall patterns can change their behavior."
