Whales Confused by Warming, UN Says
Whales, birds and other migratory creatures are suffering from global warming that puts them in the wrong place at the wrong time, a U.N. official has told 166-nation climate talks. Many creatures are mistiming their migrations, or failing to bother as changes between seasons become less clear. The shifts make them vulnerable to heatwaves, droughts or cold snaps. Migratory species are particularly vulnerable because they need separate breeding, wintering and stop-over sites. Changes to any one of the habitats can put them at risk. Whales were sometimes in the wrong place to feed on fish and plankton which were thriving closer to the poles because of warmer oceans.
