Alaska: As predicted, rising temps invited spruce beetle farther north

Exposing the Big Game's avatarThe Extinction Chronicles

=========================
Prediction is a key test of science. Scientists prove their theories when they make specific predictions that are verified by events.
========================================================================
Excerpts : A new outbreak of spruce bark beetles is killing trees across Southcentral Alaska, as far north as the Alaska Range, fulfilling a prediction by a pioneering Alaska climate change biologist.
 
A survey completed by state and federal forest officials shows dead spruce trees over nearly 450,000 acres of the region, 30 times more than 2014, and extending 200 miles north of previous outbreaks.
 
Detailed field research by Ed Berg, then a biologist with the Kenai National Wildlife Refuge, documented the climate change fingerprints of the 1990s outbreak. His evidence became news of the first major biological event driven by climate change worldwide.
 
Berg found the beetles exploded when a series of at least three summers attained a trigger air temperature. The warming…

Maybe assholes like Don Young , the rep from Alaska, won’t have the execuse to legalize killing of animals in their sleep in a remote wildlife refuge for the sake of a couple of hundred “rural Alaskans” because they have to kill for subsistence. I am still waiting for the big pandemic to do the cleansing.
