Global Warming Shrinks Sheep February 4, 2010

Sheep living on a remote island off the coast of Scotland have been shrinking for 20 years. Now it seems shorter winters caused by climate change are responsible.

Amazingly enough, global warming is blamed even though it’s cooled over the past eight of those 20 years:

So, did the study actually blame global warming for the shrinking? Not really, it blamed naturally occurring climate change (the North Antlantic Oscillation):

Over and above these factors, the modelling revealed that one of the most powerful influences on size was the gradual warming of the climate, driven by changes to the North Atlantic Oscillation ocean current, which has led to shorter winters on the island. As a consequence, the vulnerable smaller sheep were more likely to survive the winter, pushing average size down over successive generations.
