Somebody called this morning asking me if it was true that 10 trillion gallons of water had fallen on California in the last several days, as reported by several news outlets.
Yes, it’s true a Florida meteorologist ran the numbers, figuring 1 inch of rain per square mile is worth 17,378,742 gallons. So doing the math using the 3 to 5 inches of rain over more than 163,000 square miles in California, you get in the neighborhood of 10 trillion gallons.
If that estimate is even close, it helps you wrap your brain around the idea that three years of drought have really sapped California. Ten trillion gallons barely make a dent in the drought.

Tricolored blackbirds live mostly in California. There were 3 million in the 1930s, but just 145,000 survive now.

Yes, the rest of the country will see an impact from the new ozone standard, but nothing like the San Joaquin Valley and Southern California.
