OPINION: Did Jerry Brown Do Enough On Climate Change?

/in , /by /Los Angeles Timesby Jacques Leslie

Jerry Brown, in the last term of his two-part, 16-year governorship, came close to redeeming his environmental faults. Brown deserves a salute for striving to get out the message that climate change is indeed, in his words, a global “existential crisis” and that we are living in the “new abnormal.” He has been doing what a U.S. president ought to do, finding allies among nations, regions and cities for a crucial struggle — in contrast to President Trump , who abdicated the job.

Paper Outlines How L.A. County Can Adapt Its Water Supply For Climate Change

/in , /by /PHYS.orgby David Colgan

The climate is changing, Earth’s population is growing and more people are living in cities. That means urban areas—particularly those in arid or semiarid regions—need to update their water supply systems. The world was reminded of this earlier in the year with the water crisis in Cape Town, South Africa, which has a climate almost identical to that of Los Angeles. At the peak of the crisis, residents were required to limit daily water consumption to 50 liters (about 13 gallons), taking two-minute showers and letting their lawns and gardens dry up.

City’s Big Lead Revelation Doesn’t Seem To Be Impacting Schools

/in , /by /Voice of San Diegoby Ry Rivard

When schools officials began to find lead in drinking water at several San Diego schools in 2016, parents from across the region scrambled to understand the danger posed to their children by the toxic metal. At the time, we thought the lead was coming from inside schools because the city of San Diego sounded certain that its pipes were no longer made of lead. But it turns out, as we reported last week along with NBC San Diego, the city does not know what 192,000 of its water pipes are made of. Nor does it know what 16,000 pipe fittings are made of.

What Caused Nearly 20,000 Quakes At Oroville Dam? Scientists Weigh In On Mystery

/in , /by /San Francisco Chronicleby Kurtis Alexander

The earthquakes hit just days after last year’s near-catastrophe at Oroville Dam, when the spillway cracked amid heavy rains and 188,000 people fled in fear of flooding. The timing of the two small tremors about 75 miles north of Sacramento was curious, and frightening. Were the quakes part of a seismic hot spot that caused the giant concrete spillway to tear? Was the weight of the water behind the dam triggering the quakes? Could all of Lake Oroville be prone to slipping?

OPINION: Arizona Has No Choice But To Act On The Drought Contingency Plan

/in , /by /The Arizona Republic (Phoenix)

U.S. Bureau of Reclamation Commissioner Brenda Burman has issued an edict to Arizona and the two other lower Colorado basin states: Come up with a drought contingency plan by Jan. 31 or she will step in and do it for us. Burman is right to throw down the gauntlet. The Colorado River is in trouble. A nearly two-decade drought and the ravages of climate change have reduced water levels in Lake Mead, the lower basin reservoir, to record lows. Hydrologists predict water levels in Lake Mead will likely drop below levels that, under the existing multistate agreement, trigger the first tier of mandatory cutbacks in Colorado River water deliveries to lower-basin states.

40 Million Americans Depend On The Colorado River. It’s Drying Up.

/in , /by /Mother Jones (San Francisco)by Eric Holthaus

Prompted by years of drought and mismanagement, a series of urgent multi-state meetings are currently underway in Las Vegas to renegotiate the use of the Colorado River. Seven states and the federal government are close to a deal, with a powerful group of farmers in Arizona being the lone holdouts. The stakes are almost impossibly high: The Colorado River provides water to 1 in 8 Americans, and irrigates 15 percent of the country’s agricultural products. The nearly 40 million people who depend on it live in cities from Los Angeles to Denver.

High-Surf Warnings Issued As Pacific Swell Brings Big Waves To California Coast

/in , /by /Los Angeles Timesby Alejandra Reyes-Velarde and Alene Tchekmedyian

Powerful and potentially destructive waves are expected to hit California’s coast through Tuesday, bringing dangerous conditions that have prompted forecasters to urge surfers and swimmers to stay out of the ocean. A deep low-pressure center in the Gulf of Alaska and storm-forced winds are generating the Pacific swell, creating the potential for spectacularly large — and potentially dangerous — waves, said Tom Fisher, a meteorologist with the National Weather Service.

International Water Investigators To Meet Over Tijuana River Valley Sewage Spill

/in , /by /NBC 7 San Diegoby Megan Tevrizian

International water investigators will meet with Mexican counterparts Monday to discuss clean-up and repair efforts after a huge sewage spill in the Tijuana River Valley. The meeting is expected to last most of the day and will mainly cover funding for continued repair of Mexico’s sewage infrastructure. “It’s reached its life cycle,” explained Lori Kuczmanski, the Public Affairs Officer for the IBWC. “The pipes are 50 to 60 years old. They’re outdated and just old and ruptured.”

Water Shortages Ahead? Sierra Nevada Snow Pack On Track To Shrink 79 Percent, New Study Finds

/in , /by /The Mercury News (San Jose)by Paul Rogers

Every year, like a giant frozen reservoir, snow that falls across the Sierra Nevada mountain range slowly melts in spring and summer months, providing roughly one-third of the water supply for California’s cities and farms, from the Bay Area to Los Angeles. But at the current rate at which the climate is warming, the amount of runoff from Sierra snow into California’s largest reservoirs is heading for a dramatic decline — a 54 percent drop in the next 20 to 40 years and 79 percent in the next 60 to 80 years, according to a new study from scientists at Lawrence Berkeley National Laboratory.

OPINION: Gov. Brown Working To Save His Tunnels

/in , /by /San Francisco Chronicle

In the world of water politics, where change occurs at a glacial pace, the past few weeks have seen enormous swings in how our state’s most precious resource is managed and delivered. The discussions behind these changes are not easily known and even less easy to understand what they ultimately will mean for cities, farms and, yes, fish in California as climate change accelerates. What is apparent however is that Gov. Jerry Brown is working hard to put his delta tunnels project on the glide path to the finish line before he leaves office in January.
