Top Pro & Con Arguments
Glaciers are melting at unprecedented rates due to global warming, causing additional climate changes.
About a quarter of the globe’s glacial loss from 1851-2010, and approximately two thirds of glacial loss between 1991-2010, is attributable directly to global warming caused by human-produced greenhouse gases.  According to the National Snow and Ice Data Center, global warming from human-produced greenhouse gases is a primary cause of the “unprecedented” retreat of glaciers around the world since the early 20th century. 
Since 1980, glaciers worldwide have lost nearly 40 feet (12 meters) in average thickness.  According to an IPCC report, “glaciers have continued to shrink almost worldwide” over the prior two decades, and there is “high confidence” (about an 8 out of 10 chance) that Northern Hemisphere spring snow continues to decrease.  If the glaciers forming the Greenland ice sheet were to melt entirely, global sea levels could increase by up to 20 feet. Read More
