Global warming supposedly killing trees

______________________________

22 Jan 09 – Excerpts - “Trees in the western United States and Canada are dying twice as quickly as they did just 30 years ago, with rising average temperatures almost certainly to blame,” said an article today by Maggie Fox.

“These thinner and weaker forests will become more vulnerable to wildfires and may soak up less carbon dioxide, in turn speeding up global warming, they (researchers) said.

“Warmer temperatures may be encouraging pine beetles and other organisms that attack trees, the researchers said. That, along with the stress of prolonged droughts, may be accelerating death rates.

“Thomas Veblen of the University of Colorado said new regulations may be needed to help the forests survive.

"We may only be talking about an annual tree mortality rate changing from 1 percent a year to 2 percent a year, an extra tree here and there," said Mark Harmon, a professor of forest ecology at Oregon State University.”

                Did you catch that? They want to saddle us with more regulations in
                order to save “an extra tree here and there” from a threat that may -
                or may not - exist.

                And did you catch all of the qualifying words?
                     - rising average temperatures almost certainly to blame
                     - may soak up less carbon dioxide
                     - may be encouraging pine beetles
                     - new regulations may be needed
                     - may only be talking about an annual
                       tree mortality rate changing

               What about the fact that the Cascades have endured record
                snowpacks – twice - during the past ten years? There’s no
               “maybe” there. Record snowpack twice. In ten years.

                What about the fact that as we’ve headed into previous ice
                ages, the warm-weather tree line moved south?

                I think today’s dying trees could just as easily be blamed on the
                record snows.
