Example
In 1850, estimates put the number of glaciers
within what is now Glacier National Park at more
than 150. Today there are only 50 that have not
melted away. Tree ring studies indicate that glacial
retreat began around 1850.
Because these glaciers are found at relatively
low elevations, and because they are located in
the middle of the North American continent, they
are considered to be highly sensitive to global
climate change.
