Wondering if El Nino is really coming for all of us in California? Well look no further, because the NOAA National Weather Service Climate Prediction Center has answered your questions.
To sum their Aug 13th report up, “There is a greater than 90% chance that El Niño will continue through Northern Hemisphere winter 2015-16, and around an 85% chance it will last into early spring 2016.”
How can scientists tell that this is really happening? Atmospheric and oceanic conditions have been portraying El Nino features. Some of these features include increases in sea temperatures, specific movement of Kelvin waves, and exact positions of wind movement. These features emulate those of a former El Nino; the 1997 El Nino ocean temperatures were just as high as those today, and scientists say today’s El Nino may even top that of 1997.
So get out your rain jackets, boots, and skis, and prepare for the 2015/2016 El Nino that could help you to have the best shred yet.

L.A. has come up with a new design to save water moving forward during California’s drought. The main reservoir in Los Angeles has been turned into a giant ball pit. How will this help exactly? Well, the “shade balls” that cover the reservoir are made from black polyethylene and coated with an ultraviolet light-resistant material. They are also filled with water so that they don’t get swept away by wind. The 4-inch balls are supposed to last for 25 years without degradation.
Los Angeles Mayor Eric Garcetti helped to disperse some of the 96 million balls across the 175-acre reservoir as a sign that L.A. is working to save water during the drought. The reservoir, which is located in Sylmar, holds about 3.3 billion gallons, which would supply the city with drinking water for up to three weeks if need be.
“The balls cost 36 cents each, for a total of $34.5 million. The utility has been testing the concept since 2008, reporting that shade balls reduce evaporation by 85 to 90 percent. That should equate to saving nearly 300 million gallons a year, enough to provide drinking water for 8,100 people. The balls also inhibit microorganism growth, reducing the treatment the water must undergo through other means, which could save the city $250 million over time. The city says the balls will shade and cool the water, reducing evaporation from the reservoir and making it less susceptible to algae, bacterial growth, and chemical reactions that can produce harmful substances.” (National Geographic)
These shade balls will end up helping Los Angeles to cut its water use by 15 percent over a two-year period.
