Climate Change, Melting Ice…Earthquakes?

  By

Alaska researchers cited some evidence that loss of hugely heavy ice
masses on mountains will be releasing earthquakes that are currently
restrained under great pressure from above.

So earthquakes become not quite off-topic for a climate list.

This map of the world shows seismic stations that detected more than
twice the normal number of small, nearby earthquakes after the
passage of what are known as “surface waves” from major quakes that
were centered hundreds to thousands of miles away and occurred from
1992 through 2006. A new study co-authored by University of Utah
seismologist Kris Pankow found that at least 12 of the 15 major
earthquakes (greater than magnitude-7) during 1992-2006 triggered
small quakes in distant parts of the world. Scientists once believed
big quakes could not trigger distant tremors.

USDA on global warming
Climate report adds more gloom
Review out today offers clearer picture of how warming will affect
scenery familiar to Utahns
By Judy Fahys

      A landscape plagued with dust storms and drought, rangeland that
won’t support cattle, streams too hot for trout, forests felled by
beetles and fire – it’s all part of the scenario painted in a new
report on climate change by the U.S. Department of Agriculture.

     The projections are not exactly new.

     Many of them have been reported by scientists and the media in
the past five years.

Climate and High-Latitude Herbivores

“…  the plants on which they depend already have reached their peak
productivity and have begun to decline in nutritional value….”

“… leading to fewer births and to more deaths among caribou calves.”

“”Variation in the landscape provides an insurance policy for
animals, like caribou, that count on being able to climb to the top
of the next hill or go across the next valley to find plants that are
still newly emergent and highly nutritious. Climate change is
reducing the value of that insurance policy,” said Post.
