May I have the ability to reduce the uncertainties I can, the willingness to work with the uncertainties I cannot, and the scientific knowledge to know the difference.

I am using this blog to post some of the information that I come across relevant to adaptation to rapid planetary climate change. Postings will also touch upon other aspects of sustainability in a rapidly changing world.

Key Climate Change Definitions
IPCC definitions
Mitigation (of climate change)
A human intervention to reduce the sources or enhance the sinks of greenhouse gases.
Adaptation
In human systems, the process of adjustment to actual or expected climate and its effects, in order to moderate harm or exploit beneficial opportunities. In natural systems, the process of adjustment to actual
climate and its effects; human intervention may facilitate adjustment to expected climate.
Resilience
The ability of a system and its component parts to anticipate, absorb, accommodate, or recover from the effects of a hazardous event in a timely and efficient manner, including through ensuring the preservation,
restoration, or improvement of its essential basic structures and functions.

The same thing is happening all over Canada. The warmer winters and 2nd and 3rd grown forests are part of the issue. If the winter temps are below -20F for 2 weeks it will kill most of the beetle larva. With the warmer winters they are thriving through the winter. In replanted forests, the trees are too close together so the beetles can jump from tree to tree very easily.
One test area in central OR where the trees were replanted in 2-3M spacing with different species and at different planting seasons led to less beetle impact. The thinking is that the trees are farther apart and of different heights so the beetles have a harder time jumping from tree to tree.
