Many scientists regard receding glaciers as a symptom of global climate change.
While certain types of glaciers—such as surge glaciers and tidewater glaciers— are actually expanding, there are many
areas where scientists report glaciers are wasting away and that climate change is the culprit.
For instance, 150 years ago
there were 147 glaciers in Glacier
National Park. Today, only 37 glaciers remain, and scientists say they will likely completely melt by the year 2030.
Similarly, glaciers all across the Alps are retreating and disappearing every year.
What causes any given glacier to grow or shrink over time? Scientists at the United States Geological Survey (USGS), in concert with NASA and the National
Snow and Ice Data Center (NSIDC), are developing a global inventory of all the world’s glaciers to help researchers trackeach glacier’s history.
The inventory combines current information on size and movement with historical data, maps, and photos of each glacier.
The purpose is to better enable scientists to correlate changes in each glacier with any shifts in local climate, such as temperature or precipitation changes.
(For more information, read the featurearticle entitled Sizing Up the Earth’s Glaciers. )
But it is not feasible to visit and measure every major glacier on Earth. There are almost 160,000 glaciers in Earth’s polar
regions and high mountain
environments. Therefore, researchers are increasingly using satellite remote sensors to routinely survey our world’s
glaciers in a fraction of the time and cost it would otherwise take.
The false-color image above shows the Gangotri Glacier, situated in the
Uttarkashi District of Garhwal Himalaya.
Currently 30.2 km long and between 0.5 and 2.5 km wide, Gangotri glacier is one of the largest in the Himalaya.
Gangotri has been receding since 1780, although studies show its retreat quickened after 1971. (Please note that the blue contour
lines drawn here to show the recession of the glacier’s terminus over time are approximate.) Over the last 25 years, Gangotri glacier has retreated more than
850 meters, with a recession of 76
meters from 1996 to 1999 alone.
