Understanding forces of abrupt climate change Posted: 18 Feb 2015 04:16 PM PST Research of Africa's Lake Bosumtwi sediments provides insights into abrupt climate change, scientists say. The lake samples were obtained by drilling 1,000 feet to the lake's bottom and another 1,000 feet into the meteor impact structure. The sediments span 1-million years but the paper focused on the past 20,000 years.
