The most recent http://SkepticalScience.com post concerns “Climate Change Impacts on California Water Resources.”
I’m bringing it up because I’m wonder: How is our society going to prepare for these changes that are already, verifiably, underway - When most of our politicians and industrial masters-of-the-universe refuse to remove themselves from their self interest long enough to seriously, honestly learn about what is happening within our climate including its foreseeable impacts.
The problems are complex and no one knows exactly how it is going to play out, but using 5% uncertainty to justify Willful Ignorance sucks.
California’s water resources face significant strain on two fronts - a state population which is expected to grow from 35 to 55 million over the next 40 years, and a declining Sierra snowpack as a result of rising temperatures.
There is uncertainty regarding how total precipitation in California will change as the average planet and state temperatures continue to warm. Different climate models project anywhere from a modest decrease to a modest increase in net precipitation. Where the models agree is that less precipitation will fall as snow, and more as rain. . .
Rainfall Replacing Snow
Sea Level Rise
Overall Water Sustainability
Overall, while there may not be a significant change in overall precipitation falling in California as the average temperature continues to rise due to anthropogenic global warming, the challenge is in coping with the transition as the precipitation falls more as rain than snow. Finding a way to store the rainfall as we lose nature’s storage medium (the Sierra snowpack) will be difficult. . .
