New paper finds 20th century sea level rise was only 4.3 inches in S Hemisphere, 7.9 inches N Hemisphere – Published in Geophysical Research Letters
Study 'challenges the widely accepted value of global sea level rise for the 20th century' and finds sea levels rose in the southern hemisphere at only about half the rate of the northern hemisphere. According to the authors, sea levels rose only 7.9 inches in the northern hemisphere and 4.3 inches over the entire 20th century. This implies relative sea level change is primarily a localized phenomenon related to subsidence or post-glacial rebound [land height changes] rather than melting ice or steric sea level changes [thermal expansion from warming].
