Climate Change Moving Too Quickly for Some Species

Article excerpt

Climate change moving too quickly for some species: Species that inhabit flooded grasslands and savannahs will have to migrate at a speed of more than a kilometre a year if they are to keep pace with climate change over the next century, according to a US study published in Nature.

Researchers from several institutions, including the California Academy of Sciences and the Carnegie Institution for Science, combined data on current global temperatures with climate projections for the next 100 years in order to calculate the velocity of climate change in several different habitats and found that, on average, ecosystems will have to shift towards the poles by about 0.42 kilometres a year as temperatures change.

They found that the slowest-moving ecosystems would be tropical and subtropical coniferous forests (0.08 kilometres per year). Montane habitats will also be able to move slowly because a small change in elevation can result in a large change in temperature. …
