500-yr-old longest living clam reveals climate change effect
UK-based scientists studying the world's longest-living animal, a 500-year-old quahog clam, claimed to have discovered a 'worrying' effect of climate change on its shells. Growth rings on the 500-year-old animal's shells showed that from 1800, changes to the world's oceans took place at the same time or lagged behind changes to the atmosphere, instead of preceding them.
