"America cannot resist this transition [to sustainable energy sources]; we must lead it."

Standing, applauding. Thank you, President Obama!

We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires, and crippling drought, and more powerful storms. The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition; we must lead it. We cannot cede to other nations the technology that will power new jobs and new industries - we must claim its promise. That is how we will maintain our economic vitality and our national treasure - our forests and waterways; our croplands and snowcapped peaks. That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.

Key to water management adaptation? Mostly good management.

Check out an excellent blog post "Climate change and California water – past, present and future" (Jan. 13, 2013) by Professor Jay Lund from UC Davis' Center for Watershed Sciences.

He makes a few excellent points, with the bottom line that good management for climate change is mostly just good management. He points out the fact that climate change isn't the only signal that managers will have to monitor: "In the past 100 years, California water management has changed tremendously, driven by changes in population, economic structure, technology, and social and environmental objectives."

He also points out that we don't necessarily need any more reservoirs here in California: "with some changes in reservoir management, existing large reservoirs on most of California’s rivers can largely accommodate seasonal shifts in runoff." And, an important detail for those wringing their hands over California's warming climate: precipitation and other unknowns are probably more important to monitor than temperature.

Change in total precipitation is more important than warming alone. The physical, economic and ecological instability of the Sacramento-San Joaquin Delta probably poses more risk to California’s water supply than climate warming.

Next weekend I expect to be heading up to the California Water Law Symposium at UC Davis, where I'm sure I'll hear more wisdom from Professor Lund's corner.
