As California water officials confirmed Thursday that the snowpack in the Sierra Nevada remains well above average, pressure was mounting on the state to lift emergency water restrictions that have been in place for two years.

The snowpack across the mountains is now 164 percent of average, a closely watched marker in the nation's most populous state — and biggest economy — where one-third of all the drinking water comes from snow-fed reservoirs.

The astronomer Carl Sagan said that extraordinary claims require extraordinary evidence. Last week, a physician made the extraordinary claim that he had an effective treatment for sepsis, sometimes known as blood poisoning.

Sepsis is a bodywide inflammation, usually triggered by infection, and the leading cause of death in hospitals, taking 300,000 lives a year. So, even a 15 percent improvement in survival would save 40,000 lives — the number of Americans who die on the highway each year, or from breast cancer.

Our southern neighbor is the United States' leading supplier of fresh produce, providing 70 percent of the fresh vegetables we import and more than 40 percent of our fresh fruit imports. That trade has boomed since NAFTA — the North American Free Trade Agreement — was signed in 1994.
