California's Worst Drought in 1,200 years
It does sound like lunacy, the worst drought in 1,200 years. If you went back in time, it would be 800 A.D., a time of Vikings pillaging Europe and when China invented gunpowder! That is what a study of 278 blue oak trees in Central and Southern California. By examining the tree rings and their width, the rings show how wet each year was because a tree grows more in a wet season. Once the data was gathered, it was compared to tree rings of sequoias and bristlecone pines that go back 1,200 years. The report did say that during the 1,200 year period, the state did go through three year drought periods before, but not as bad as the current that began in 2012. Changed weather patterns caused by global warming is the root cause.
The past three years of drought is misleading. It is not like California did not receive rain, it did, but far less than what is considered to be normal. And, how much water does California need to recover from this epic drought?
According to NASA scientists, the state would need 11 trillion gallons of water! NASA satellites confirm that the state loses 4 trillion gallons of water per year from its rivers and basins. This is more than its citizens use in a year. The snowpack in the Sierras remains the worst since 1977. Meteorologists state at least eight "super" soaker storms are needed to balance things out like the recent past one where up to eight inches of rain fell.
And to think some still do not believe in global warming.OMG.
