Oops: Climate Change Has Nothing To Do With Altering Forest Tree Compisition

Another Warmist talking point down the drain. What’s funny is this comes from Penn State, home of Michael “Hockey Schtick” Mann

(PSU News) Change in disturbance regimes — rather than a change in climate — is largely responsible for altering the composition of Eastern forests, according to a researcher in Penn State’s College of Agricultural Sciences.

Forests in the Eastern United States remain in a state of “disequilibrium” stemming from the clear-cutting and large-scale burning that occurred in the late 1800s and early 1900s, contends Marc Abrams, professor of forest ecology and physiology.

Moreover, Abrams noted, since about 1930 — during the Smokey Bear era — aggressive forest-fire suppression has had a far greater influence on shifts in dominant tree species than minor differences in temperature.

“Looking at the historical development of Eastern forests, the results of the change in types of disturbances — both natural and man-caused — are much more significant than any change in climate,” said Abrams, who is the Steimer Professor of Agriculture in the Department of Ecosystem Science and Management.

“Over the last 50 years, most environmental science has focused on the impact of climate change. In some systems, however, climate change impacts have not been as profound as in others. This includes the forest composition of the eastern U.S.”

The very fact is, changes in climate will have some effects. And, the Earth is in a constant state of flux. During the Holocene, for one, there have been swings between warm and cool, with pauses, as well as short term cooling/warming during the cool/warm periods. The debate is not about climatic changes, which occur, but causation. Warmists hyperventilate that the current changes are mostly/solely caused by Mankind. Skeptics say it is mostly/solely caused be nature. Interestingly, the Warmists are so concerned that they mostly refuse to take even token measures in their own lives to reduce their “carbon footprints”.

Also, interestingly, what Professor Abrams is partly referring to is land use, which can have a profound affect on more localized climate (micro-climate), which creates false readings for global aspects.

    Teach typed, risibly: “Warmists hyperventilate that the current changes are mostly/solely caused by Mankind. Skeptics say it is mostly/solely caused be (sic) nature.”

    Here is the corrected version: “Climate scientists have demonstrated that the current century long bout of global warming largely results from increased CO2 from humans burning fossil fuels, while Deniers hyperventilate, without evidence, that some unidentified “natural” force is causing the warming.”

    You’re welcome.

    The scientists did not conclude that “Climate Change Has Nothing To Do With Altering Forest Tree Compisition (sic)” as you falsely claim. This is a common ploy of dishonest conservabloggers – false headlines not supported by the body of the post. And misspelled words. One of the authors said: “Many ecological phenomena combine to direct vegetation trends over time, with climate and disturbance playing prominent roles,” said Nowacki…” and “In most cases, however, European disturbance overrode regional climate change,” Abrams said.

    And at no time do the authors suggest that global warming is a hoax or is not happening. Professor Mann was not mentioned except by you.

    You see, real scientists work this way – following evidence wherever it leads. This latest paper concluded that in the Eastern US “European disturbance overrode regional climate change”. I suspect that if the data are reliable Professor Mann will be quite pleased. That’s the way real science works.

    That climate change is not the primary driver of maples replacing conifers in the Eastern US does not change the facts of global warming. That too is how real science works.

    Looks to me like a all time hottest year Teach , if do will you pause on the pause ?

    You are wrong. There is no evidence or logic to support your claims.

    You’ve become trite in your blanket dismissals of all things you don’t understand or that you don’t wish to address.

    Select one claim that I made and refute it. Thanks.
