Climate Change Notes

Slide 1: There has been a lot of debate about the reality of climate change. The best way to evaluate this is to look at a place where the impact is obvious and ongoing.

Slide 2: Some of the places where the impact of climate change is most obvious are coastal islands in the Arctic, where ice cover typically reduces the erosive impact of winter storms and where small changes in sea level can have significant impact.

Slide 3: The Bering Land Bridge Preserve is one of the most westerly points in North America (only the Aleutian Islands are farther west. The village of Shishmaref is located on a barrier island and is closer to Siberia (Russia) than any other part of North America. Images: www.nps.gov/bela/html/vvcenter.htm

Slide 4: This national park is the only part of the former Bering Land Bridge (which was several hundred miles across) that remains above sea level. With continued climate change this will no longer be the case.

Slide 5: This is not Shismaref, but an Inuit Village in Arctic Canada that is also locked in by sea ice. This shows what relatively normal spring sea ice would look like.

Slide 6: Bearded seals and walrus live on the pack ice year round, moving with it as it ebbs and flows. Moose and birds are hunted during late spring through early fall, when pack ice is well offshore and marine mammals are inaccessible.

Slide 11: In these images you can see the erosion and the effects of a winter storm that normally would just be wind because the Bering Sea would have frozen by October. Source and Images http://www.arctic.noaa.gov/detect/human-shishmaref.shtml
