Pictures of how global warming is affecting us
These pictures are good examples
of how global warming is affecting us, notice the before and after photos.
The Arctic is thawing very rapidly, documented by new
reports from scientists and arctic natives. The Arctic Climate Impact Assessment was
released in late 2004, and shows changes from the ice at the North Pole to animals and
human settlements. More recent reports from Greenland show outlet glaciers moving meters
per hour and rapidly thinning. The Arctic Ocean ice cap is shrinking in summer to the
smallest it has ever been in modern measurements, and even winter cold has not been
refreezing it as extensively as before. That sea ice is habitat for the polar bear.
Declines in bear nutrition, birth weight and survival have moved the U.S. government
(urged by three environmental groups) to propose the bear be named a species threatened
with extinction.

BEFORE: Take a look at Agassiz Glacier, in this photograph taken in 1913, near Boulder
Pass, Glacier National Park. NEXT IMAGE: Agassiz Glacier (2005) Click to enlarge.

AFTER: Compare it to this 2005 photograph of Agassiz Glacier taken from the same
location (near Boulder Pass, Glacier National Park)
Boulder Glacier (1932)
BEFORE: Shown above is a picture of Boulder Glacier, taken near Boulder Pass, Glacier
National Park, in 1932. The foreground rocks provided an excellent reference point to
re-photograph the historic photo.
Boulder Glacier (2005)
AFTER: Boulder Glacier photographed from nearly 73 years later from the same place as
the 1932 photo. The foreground rocks provided an excellent reference point to
re-photograph the historic photo.
Swiftcurrent Glacier (1900)
BEFORE: Photograph of the Swiftcurrent Glacier, taken in 1900 from the Swiftcurrent
trail, Glacier National Park.
Swiftcurrent Glacier (1998)
