Data from many sources and at several scales suggest that recent climate change is already affecting terrestrial Arctic ecosystems. Comparisons of historical and contemporary aerial photographs provide evidence that Arctic vegetation has already undergone significant shifts in recent decades, foreshadowing changes that are likely to come. In a repeated measurement study conducted on Ellesmere Island, Nunavut, Canada, over a period of 13 years, the plant community became more productive over time, suggesting that the ecosystem is in transition.
