10 Photos Showing Evidence of Climate Change on Alaskan Glaciers

(ref: US Geological Survey usgs.gov)

Here are some comparative photos from the US Geological Survey showing evidence of climate change on glaciers in Alaska. Most startling are the photos of Bear Glacier showing the change over just a 5 year period from 2002 to 2007.  You can view the USGS report at http://www.usgs.gov/global_change/glaciers

How We Know What We Know About Our Changing Climate (available from Reach and Teach) shows the science behind the headlines – evidence from flowers, butterflies, birds, frogs, trees, glaciers and much more, gathered by scientists from all over the world, sometimes with assistance from young “citizen-scientists.” And here is what young people, and their families and teachers, can do to learn about climate change and take action. Climate change is a critical and timely topic of deep concern, here told in an age-appropriate manner, with clarity and hope.
