Until recently, if a chalk cliff collapsed it was blamed on waves eroding its base, or the chalk weakening as it became saturated with water. But in Brighton in 2001 a cliff behind a seawall that protected it from these processes began to collapse, and scientists questioned why. http://phys.org/news285577542.html Space & Earth Fri, 19 Apr 2013 08:05:52 EST news285577542 A new map of the places in Scotland that offer good habitats for one of the most invasive kinds of rhododendron may help control the spread of Sudden Oak Death, a disease that threatens trees and plants like oak, beech, larch and bilberry. http://phys.org/news285486433.html Biology Thu, 18 Apr 2013 06:47:44 EST news285486433 A sudden switch from herring to sardines in the English Channel in the 1930s was due to a long-term ocean cycle called the Atlantic Multidecadal Oscillation (AMO), an international study shows.
