Scientists map speed of climate change for different ecosystems

ScienceDaily (2009-12-24) -- From beetles to barnacles, pikas to pine warblers, many species are already on the move in response to shifting climate regimes. But how fast will they -- and their habitats -- have to move to keep pace with global climate change over the next century? Scientists have calculated that on average, ecosystems will need to shift about 0.42 kilometers per year to keep pace with changing temperatures across the globe.
