The British Trust for Ornithology has prepared a report on apparent impacts of climate change on migratory species. Includes birds that are wintering in Britain, or parts of Britain, in higher numbers – rather than moving south/west to warmer places; also variations in ranges of some marine animals inc cetaceans. Notes that, "Although it is thought that no species has yet become extinct solely because of climate change (Golden Toad is a possible exception), many extinctions (of both migratory and non-migratory species) are predicted in the near future." summary:
