I blog about environmental and social justice issues because I am very concerned about the health of the interdependent web of life of which we are a part.

Wildfires 2010

I cannot see past the house across the street - no trees - no mountains - no river - just a wall of grey smoke.   Even the dog sneezes when she spends time outdoors as the air quality is very poor.   I think I'll take another anti-histamine while I consider the fact that most of our summers may be like this one - hot , smoky, and miserable. 

An article in Scientific American states
fires are not just a result of a changing climate, they're also contributing to the overall warming trend much more than imagined, the authors report. As vegetation burns, it releases stored-up carbon into the atmosphere, speeding global warming and thereby exacerbating conditions that may generate a greater incidence of wildfires in the coming years. But across the globe, fires have been getting larger and stronger. "We are witnessing an increasing instance of these megafires," says Thomas Swetnam, director of the Laboratory of Tree-Ring Research at the University of Arizona.
In other words, wildfires are partly a result of climate change - and accelerate climate change at the same time.   BC is particlarly vulnerable to this feedback loop due to all the pine beetle killed trees.   A wonderful prospect......
