Even though the oceans tend to warm slower than the land, researchers report in the Nov. 4 issue of the journal Science that similar movement rates are needed for organisms to stay ahead of climate change on land and in the oceans. After analyzing 50 years of global temperature and climate data, Michael Burrows of the Scottish Marine Institute in Argyll and his colleagues found that the speed and direction of climate change, along with the arrival time of various seasons, is happening just as fast in the oceans as on land. The research team says that this climate change velocity and seasonal shifts can be used to predict shifts in habitat ranges and life cycle changes in a warming world.
