27/7/2015, The Vane, El Niño Probably Won’t Solve California’s Dire Drought: If anyone is eagerly following news of the strengthening El Niño in the Pacific, it’s California. Strong El Niño events have a history of bringing drenching rain to the West Coast during the winter months, and we could see that play out this year. However, don’t get too wrapped-up in the hype—it’s going to take more than one rainy stretch to ease the damage done by the lasting drought. In order to understand what El Niño may or may not do for California, we need to understand El Niño itself, and shockingly (!!!) the national media doesn’t do a great job explaining things that could get them a lot of ratings if they spin it just right (see: polar vortex)….
….The latest update of the drought monitor doesn’t paint a pretty picture across the western United States. Believe it or not, the drought has improved by a hair since September 30—California started the water year with 58% of the state in an exceptional drought, which is the worst of the five categories. As of last Tuesday, only (“only”) 46% of the state is in an exceptional drought. Any progress is progress, I guess.The intensity and duration of this drought is unprecedented in the modern era, and it’s going to take more than a month or two of rain to fix what’s gone so horribly wrong over the past couple of years. The problem with the potential of seeing big bursts of heavy rain is that much of the rain will run off, helping reservoirs and bodies of water no doubt, but causing floods, mud and landslides in the process, not to mention the water being unable to seep into and rejuvenate the soil. This doesn’t even begin to cover the fact that (currently non-existent) snowpack is a huge water resource in the state.Read More here
