Are Glaciers Melting?

Are glaciers melting?  Yes.  They do every year during warmer seasons.  They also grow back during colder seasons.  From the data, it does suggest most are are melting more than they grow.  That said, not all do--and a significant portion do not, including many in Greenland, and especially in Antarctica recently where growth dwarfs the area of most other northern glaciers combined.

Oscillations in the Antarctic and Arctic are below.  Notice the enormous fluctuations are in millions of square kilometers.  Notice also the time scale only goes back to 1979.  There is often an increase in the Southern Hemisphere when there is a decrease in the Northern Hemisphere.

The most recent growth in Antarctica is so massive it is actually contributing to a lowering of sea level rise.

Earth has had five ice ages that scientists can determine.  The most recent ice age ended about 11,000 years ago.  A look at the Earth's temperatures over the millennia shows this relatively recent warming trend is not the largest ever threat to mankind.

From a geologic standpoint the Earth is in a warming phase--not man made, but natural--so many glaciers should naturally be melting away, otherwise much of Northern US would be under ice.  I'm sure the people of Michigan, Wyoming, and Montana are glad it's warmed up.  Perhaps the people of Canada, Alaska, Scandinavia, and Siberia will be, too.
