California Records Driest Year in a Century

In a year of both extreme heat and extreme drought, California has reported its driest water year in terms of precipitation in a century, and experts fear the coming 12 months could be even worse.

The Western Regional Climate Center added average precipitation that had been reported at each of its stations and calculated that a total of 11.87 inches of rain and snow fell in California in the 2021 water year. That’s half of what experts deem average during a water year in California: about 23.58 inches.

Much-needed Rain Finally Falling in the Bay Area; Snow in the Sierra

Light rain started falling Sunday evening in the Bay Area, as a week of much-needed precipitation was forecast for the parched Northern California landscape.

One to 2 inches of rain is expected to fall across the Bay Area over the next week, and even more could fall across the North Bay as a series of storms dives in from the northwest, said Rick Canepa, meteorologist with the National Weather Service. To the east, parts of the Sierra Nevada could see more than a half-foot of snow by Monday morning.

Scientists See a La Niña Coming. What Does That Mean for the Dry American Southwest?

The wet winter the American south-west has hoped for as it battles extreme drought and heat is increasingly unlikely to materialize as scientists now predict that a phenomenon known as La Niña will develop for the second year in a row.

The weather system could intensify the worst effects of the drought that much of the region already finds itself in, including higher wildfire risks and water shortages through 2022.

Opinion: Madera County’s Groundwater Situation Is Dire. New Efforts Are Underway to Address It

The Sustainable Groundwater Management Act (SGMA) made the County of Madera responsible for groundwater management for the more than 200,000 acres that are not part of an irrigation or water district (the “white areas”) in Madera County. Like many regions in the Central Valley, Madera County is heavily groundwater dependent. The average annual shortage in the Madera subbasin alone is approximately 165,000 acre-feet per year, a number calculated over a 50-year period to account for both wet and dry periods.

 

Vice President Kamala Harris to Visit Lake Mead Monday, Address Climate Change

Vice President Kamala Harris will visit Southern Nevada on Monday and is scheduled to talk about climate change and investing in climate resilience.

White House communications report the vice president is planning to be at Lake Mead at around noon. Harris is scheduled to participate in a tour, receive a briefing, and deliver remarks making the case for the largest investment in climate resilience in U.S. history through passing the Build Back Better Agenda and the Bipartisan Infrastructure Deal.

Q&A: La Niña’s Back and It’s Not Good for Parts of Dry West

For the second straight year, the world heads into a new La Niña weather event. This would tend to dry out parts of an already parched and fiery American West and boost an already busy Atlantic hurricane season.

Just five months after the end of a La Niña that started in September 2020, the U.S. National Oceanic and Atmospheric Administration announced a new cooling of the Pacific is underway.

 

The Drought in California This Summer Was the Worst on Record

The West’s historic, multi-year drought is threatening water supply, food production and electricity generation. It has drained reservoirs at incredible rates and fueled one of the most extreme wildfire seasons the region has ever experienced.

In California, drought conditions this summer were the most extreme in the entire 126-year record — a clear sign of the role climate change plays in the perilous decline of the state’s water resources. Data from the National Oceanic and Atmospheric Administration shows that drought months are becoming the new normal, with rainy months becoming fewer and farther between.

Water Budgets and Drought Fees Coming to 1 Million Residents in San Jose and Neighboring Communities

In the latest fallout from the worsening drought, residents of San Jose — which received the lowest rainfall in its recorded history last year — and surrounding communities are about to be given tougher water conservation rules than any major city in California.

The San Jose Water Company, a private firm that provides drinking water to 1 million people in San Jose, Cupertino, Campbell, Los Gatos, Saratoga and Monte Sereno, has begun sending notices to residents informing them it is moving forward with mandatory rules to set monthly residential water budgets with financial penalties for homeowners who exceed them.

Agencies Warn of Cyber Threats to Water, Wastewater Systems

A coalition of federal agencies on Thursday warned that hackers are targeting the water and wastewater treatment sectors, strongly recommending that organizations take steps to protect themselves.

In a joint advisory, the FBI, the Cybersecurity and Infrastructure Security Agency (CISA), the Environmental Protection Agency (EPA) and the National Security Agency (NSA) warned of “ongoing malicious cyber activity—by both known and unknown actors—targeting the information technology (IT) and operational technology (OT) networks, systems, and devices of U.S. Water and Wastewater Systems (WWS) Sector facilities.”

“This activity — which includes attempts to compromise system integrity via unauthorized access — threatens the ability of WWS facilities to provide clean, potable water to, and effectively manage the wastewater of, their communities,” the agencies wrote in the advisory.

La Niña Arrives, Threatening to Stoke Droughts and Roil Markets

A weather-roiling La Niña appears to have emerged across the equatorial Pacific, setting the stage for worsening droughts in California and South America, frigid winters in parts of the U.S. and Japan and greater risks for the world’s already strained energy and food supplies.

The phenomenon—which begins when the atmosphere reacts to a cooler patch of water over the Pacific Ocean—will likely last through at least February, the U.S. Climate Prediction Center said Thursday. There is a 57% chance it be a moderate event, like the one that started last year, the center said.
