Read the following abstract and data figure from a research paper.
1. What hypothesis are the researchers testing with these data?
2. Describe the results presented in the figure—what do you conclude from interpreting these data?
Do you think the researchers’ hypothesis was correct?
3. Explain how anthropogenic climate change will have (or has had) direct negative effects on you
personally, and describe the ultimate causes of anthropogenic climate change.
4. Describe specific actions you can take (or have taken) to lessen your contribution to anthropogenic
climate change.

Chen, et al. (2011) Rapid range shifts of species associated with high levels of climate warming.

Abstract
The distributions of many terrestrial organisms are currently shifting in latitude or elevation in
response to changing climate. Using a meta-analysis, we estimated that the distributions of species
have recently shifted to higher elevations at a median rate of 11.0 meters per decade, and to higher
latitudes at a median rate of 16.9 kilometers per decade. These rates are approximately two and
three times faster than previously reported. The distances moved by species are greatest in studies
showing the highest levels of warming, with average latitudinal shifts being generally sufficient to
track temperature changes. However, individual species vary greatly in their rates of change,
suggesting that the range shift of each species depends on multiple internal species traits and
external drivers of change. Rapid average shifts derive from a wide diversity of responses by
individual species.
