Global warming is disrupting wildlife and the environment on every continent, according to an unprecedented study that reveals the extent to which climate change is already affecting the world's ecosystems.

Scientists examined published reports dating back to 1970 and found that at least 90% of environmental damage and disruption around the world could be explained by rising temperatures driven by human activity.


Big falls in Antarctic penguin populations, fewer fish in African lakes, shifts in American river flows and earlier flowering and bird migrations in Europe are all likely to be driven by global warming, the study found.
