Researchers: Expect more wildfires
By BRETT FRENCH
Of The Gazette Staff

JACKSON – Now might be a good time to get into the firefighting business.

If science and history are a guide, the world and
particularly the Rocky Mountain West are poised
on the cusp of a dangerous increase in the size
and frequency of large fires, caused by a warming
climate.

“By the end of this century we’re expecting the
area in Canada that burns to double,” said Mike
Flannigan, a research scientist with the Canadian
Forest Service. “Others say it will be a change
of three to five times. It looks pretty gloomy.”

Forests and the Atmosphere: New NCAR Experiment

————————————————————————-
“Forests help control the atmosphere, and there’s a big difference
between the impacts of a living forest and a dead forest,” says NCAR
scientist Alex Guenther, a principal investigator on the project. “With
a dead forest, we may get different rainfall patterns, for example.”

Pine Bark Beetles Affecting More than Forests
September 24, 2008

Pine bark beetles appear to be doing more than killing large swaths
of forests in the Rocky Mountains. Scientists suspect they are also
altering local weather patterns and air quality.

A new international field project, led by scientists at the National
Center for Atmospheric Research (NCAR) in Boulder, Colo., is
exploring how trees and other vegetation influence rainfall,
temperatures, smog and other aspects of the atmosphere.

Plants take in and emit chemicals that affect the air, and they also
absorb varying amounts of incoming heat from the sun. When portions
of a forest die, the local atmosphere can change in subtle ways.

Unfortunate Milestone: Autumn Equinox, 2008

Unfortunate Milestone: Autumn Equinox, 2008

http://www.footprintnetwork.org/gfn_sub.php?content=overshoot

September 23 this year marks an unfortunate
milestone: the day humanity will have used all
the resources nature will generate this year,
according to Global Footprint Network data. Earth
Overshoot Day marks the day when humanity begins
living beyond its ecological means. Beyond that
day, we move into the ecological equivalent of
deficit spending, utilizing resources at a rate
faster than what the planet can regenerate in a
calendar year.

Globally, we now now require the equivalent of
1.4 planets to support our lifestyles. But of
course, we only have one Earth. The result is
that our supply of natural resources — like
trees and fish — continues to shrink, while our
waste, primarily carbon dioxide, accumulates.
