New study: Ecosystems are resilient to global warming!

Here comes another huge disappointment for the global warming alarmist community:

Ecosystems are basically unaffected and adapt well to a warmer climate, according to a fresh study, published in the journal BioScience:

An analysis of 35 headwater basins in the United States and Canada found that the impact of warmer air temperatures on streamflow rates was less than expected in many locations, suggesting that some ecosystems may be resilient to certain aspects of climate change.
The study was just published in a special issue of the journal BioScience, in which the Long-Term Ecological Research (LTER) network of 26 sites around the country funded by the National Science Foundation is featured.
Lead author Julia Jones, an Oregon State University geoscientist, said that air temperatures increased significantly at 17 of the 19 sites that had 20- to 60-year climate records, but streamflow changes correlated with temperature changes in only seven of those study sites. In fact, water flow decreased only at sites with winter snow and ice, and there was less impact in warmer, more arid ecosystems.
“It appears that ecosystems may have some capacity for resilience and adapt to changing conditions,” said Jones, a professor in OSU’s College of Earth, Ocean, and Atmospheric Sciences. “Various ecosystem processes may contribute to that resilience. In Pacific Northwest forests, for example, one hypothesis is that trees control the stomatal openings on their leaves and adjust their water use in response to the amount of water in the soil.
“So when presented with warmer and drier conditions, trees in the Pacific Northwest appear to use less water and therefore the impact on streamflow is reduced,” she added. “In other parts of the country, forest regrowth after past logging and hurricanes thus far has a more definitive signal in streamflow reduction than have warming temperatures.”


One can hear the alarm bells ringing in the cathedrals of climate change. The high priests are most certainly already preparing a counter attack in order to silence the heretics, who dare to say that doomsday is not coming.
