Mountain glaciers and snow cover have decreased in both the Northern and Southern hemispheres.18 The ice sheetscovering Antarctica and Greenland appear to be melting faster than predicted.19 Since 1993, global average sea level has risen at an annual average rate of 3.1 mm.20 Along most of the U.S. coast theEnvironmental Protection Agency reports that sea level rose 10 to 12 inches over the past century.21 Areas across the world experiencing serious drought more than doubled from the 1970s to the early2000s, and VS. government scientists pointed to rising global temperatures as a major factor.22 Researchers also reported that hurricanes became more destructive over the past 30 years.
