I have been studying California climate history for years to understand global warming issues in the state. Most recent I was reading The West Without Water, which catalogs the states long drought history. Histories driven by our location next to the Pacific Ocean, the lagest body of water on the planet. When the Pacific Decadal Oscillation (PDO) is negative California is dry for decades. It has been that way for millions of years, according to the paleoclimatology record. What is it that Governor Brown does not understand about California’s climate history?
Portraying California as the front line of climate change, Gov. Jerry Brown said Monday that the effects of man-made global warming were devastating the state, drawing a direct link between climate change and both the record-setting drought that has left the state parched and the early-season wildfires that broke out across California last week. He declared that people must find a way “to live with nature, not collide with it.”
If California has a long history of droughts, especially during negative PDO which we are currently experiencing, how are humans responsible? Some droughts lasted for decades. If the state has a long history of droughts long before humans had SUVs and power plants, how can humans be responsible man-made global warming now, which Gov. Brown is blamed for the current drought? It has happend for millions of years before humans were burning fossil fuels. So, why are humans now responsible for the drought?
Maybe readers can help me understand this new connection. How have humans been able to negated climate history and inserted their own influence? Are we powerful enough to challenge Mother Nature?
