As for politics, having a Climate-Denying Party in charge would only exacerbate the problems facing us.
The L.A. Basin...and nearly the entire Southwest (i.e. Colorado River states)...has experienced decreasing rainfall since the start of the 20th century. More recently, L.A. has seen short bursts of high rainfall that caused rapid growth of chaparral in the hills, followed by this past year's drought (only 16% of normal rainfall) accompanied by higher than normal Santa Ana winds...a recipe for this disaster...and nothing to do with Liberal vs Conservative Social Politics.
Note that Southern California depends on the Colorado River for 60% of its water...and as mentioned, that source is under GREAT stress...just ask the residents of Arizona and Las Vegas.
The issue is Climate Change...let's all get together on this 'Common Ground' problem.
