OPINION: Effect Of Rising Seas Has A Time Line And Cost

/in , /by /San Francisco Chronicle

California’s fabled beaches are shrinking, with waves and tides eventually expected to slosh over thousands of coastal homes and businesses. That’s the entirely plausible prediction from scientists studying climate change and rising ocean levels linked to hotter temperatures. In less than 30 years, rising waters will flood about 20,000 homes along the state’s shoreline. A warmer ocean is expanding and polar ice sheets are melting, pushing up sea levels here by nearly 2 feet. And it’s coming faster than ever, with lapping water noticeable by 2035 and the serious trouble a decade later.

As Rainy Season Comes To A Close, Officials Call For Conservation

/in , /by /The Hub (Los Angeles)by Hugo Guzman

It was only a few years ago that climatologists like Jet Propulsion Lab’s Bill Patzert were warning Angelenos that rainy days could soon be a distant memory. The period between late 2011 and 2014 was the driest in California history since record-keeping began, according to the Western Regional Climate Cente.

Water Use Across The United States Declines To Levels Not Seen Since 1970

/in , /by /USGS (Reston, Va.)

Water use across the country reached its lowest recorded level in 45 years. According to a new USGS report, 322 billion gallons of water per day (Bgal/d) were withdrawn for use in the United States during 2015. This represents a 9 percent reduction of water use from 2010 when about 354 Bgal/d were withdrawn and the lowest level since before 1970 (370 Bgal/d).

The Two Biggest Challenges To Groundwater Recharge In California

/in , /by /Water Deeply (New York)by Alvar Escriva-Bou

The wet winter of 2017 brought an opportunity to test groundwater recharge – the intentional spreading of water on fields to percolate into the aquifer – as a tool for restoring groundwater levels and helping basins comply with the Sustainable Groundwater Management Act (SGMA). This is especially important in the San Joaquin Valley, which has the biggest imbalance between groundwater pumping and replenishment in the state.

Report Finds Industrial Chemicals In Water Supply More Toxic Than Thought

/in , /by /KQED (San Francisco)

A family of industrial chemicals turning up in public water supplies around the country is even more toxic than previously thought, threatening human health at concentrations seven to 10 times lower than once realized, according to a government report released Wednesday. The chemicals are called perfluoroalkyl and polyfluoroalkyl. They were used in such goods as fire-suppressing foam, nonstick pans, fast-food wrappers, and stain-resistant fabric and carpet, but are no longer used in U.S. manufacturing. Water sampling has found contamination in water around military bases, factories and other sites.

A Deep Dive Into Groundwater, Desalination

/in , /by /Capitol Weekly (Sacramento)by Keith Van Der Maaten

At the height of the recent drought, the legislature passed and Gov. Brown signed legislation, the Sustainable Groundwater Management Act (SGMA), that for the first time required California water agencies to account for groundwater pumping and held them accountable for the development of sustainable plans for the future. Groundwater accounts for approximately 30% of the state’s water supply.

California Limits Daily Personal Water Use to 55 Gallons – Kind Of

/in , /by /Water Deeplyby Matt Weiser

California has always been America’s leader on environmental policy, and water is no exception. So it was hardly surprising when the state made headlines across the nation in early June with a new policy on residential water use: Californians will be limited to 55 gallons per person per day for their indoor water needs.

Intense wildfire seasons now normal in California

While the 2017 fire season was a perfect storm culminating five years of drought, a heavy rain year and a hot summer, the 2018 fire season has already begun. This year, with the relatively light snowpack, CalFire officials are keeping a close eye on elevations above 6,500 feet that have already begun to dry out.

Drought woes? This tech can literally make it rain

/in , /by /CNNby Kaya Yurieff

Don’t call them the weather gods, but this company can actually make it rain. North Dakota-based Weather Modification International uses planes to target clouds and draw out more rain from them. The concept, called cloud seeding, has been around for decades. But there is new urgency due to climate change and a rapidly growing global population, which have disrupted global water supplies.

Warned 30 Years Ago, Global Warming ‘Is In Our Living Room’

/in , /by /Associated Press by Seth Borenstein and Nicky Forster

On June 23, 1988, a sultry day in Washington, James Hansen told Congress and the world that global warming wasn’t approaching — it had already arrived. The testimony of the top NASA scientist, said Rice University historian Douglas Brinkley, was “the opening salvo of the age of climate change.” Thirty years later, it’s clear that Hansen and other doomsayers were right. But the change has been so sweeping that it is easy to lose sight of effects large and small — some obvious, others less conspicuous.
