A better indicator of climate change is studying glacier mass, which has reduced significantly over the 20th and 21st centuries. If glaciers lose more ice than they can accumulate through new snowfall, they ultimately add more water to the oceans, leading to a rise in sea level (see the Sea Level indicator).
