Small Towns Grow Desperate for Water in California

/in , , /by /The New York Timesby Thomas Fuller

As a measure of both the nation’s creaking infrastructure and the severity of the drought gripping California there is the $5 shower.

That’s how much Ian Roth, the owner of the Seagull Inn, a bed-and-breakfast in this tourist town three hours north of San Francisco, spends on water every time a guest washes for five minutes under the shower nozzle.

Water is so scarce in Mendocino, an Instagram-ready collection of pastel Victorian homes on the edge of the Pacific, that restaurants have closed their restrooms to guests, pointing them instead to portable toilets on the sidewalk.

Wildfires Are Threatening Municipal Water Supplies

/in , , /by /EOSby Alex Tat-Shing Chow, Tanju Karanfil, and Randy A. Dahlgren

In recent decades, wildfire conflagrations have increased in number, size, and intensity in many parts of the world, from the Amazon to Siberia and Australia to the western United States. The aftereffects of these fires provide windows into a future where wildfires have unprecedented deleterious effects on ecosystems and the organisms, including humans, that depend upon them—not the least of which is the potential for serious damage to municipal water supplies.

In 2013, the Rim Fire—at the time, the third-largest wildfire in California’s history—burned a large swath of Stanislaus National Forest near Hetch Hetchy Reservoir, raising concerns about the safety of drinking water provided from the reservoir to San Francisco.

Why Can’t We Build a Desalination Facility Off the Coast of California Near Drought-ridden Cities?

/in , /by /ABC10by Walt Gray

Today’s Why Guy question comes from Todd, who asks, “Why can’t we build just one solar/hydro-powered desalination plant off the coast of California nearest the most drought-ridden city/cities?”

Todd, as we sit squarely in the middle of another drought, adding more seawater desalination facilities has become a louder discussion. Right now, California has 12 desalination facilities in operation, but there are calls for more.

Can Water Megaprojects Save The US Desert West? (Part 2)

/in , /by /CleanTechnicaby Jennifer Sensiba

In part one of this article, I covered the American West’s water problems, as well as some of the ways they have been solved with big engineering projects so far. Now, with climate change and growth both pushing the limits of water supplies, people are asking for even bigger projects, like a pipeline from the Mississippi River to somewhere in the Colorado River’s basin. Let’s talk about those ideas, even bigger ones, and why none of them might be a good idea.

Arizona state legislators asked Congress to consider a pipeline that dumps Mississippi water into the Green River, but there are alternate possibilities.

Trees: Landscaping MVP (Most Valuable Plant)

/in , /by

New waterwise landscaping represents a significant investment in time and cost. Trees stand out as the most valuable players in your landscape design. No other landscape plant offers greater benefits to your landscape and the environment as a whole.

Trees save energy and clean the air.  They counteract the urban heat island effect and fight climate change. Trees provide property protection and improve property values. Neighbors with more trees even have lower crime rates.

Investing in tree maintenance is vital to keep them healthy. Tree pruning should only be done for a specific reason. First, for corrective or preventative measures.  Second, to remove dead, crowded, or poorly angled branches or to reduce potential hazards. Third, to increase light and air penetration for healthy growth.

Tips from pros on pruning and thinning trees

Routine thinning does not always improve the health of a tree. Removing large amounts of foliage all at once can put stress on a tree’s stored energy reserves, resulting in stunted growth.

Pruning should be performed in the best season for the tree to avoid potential disease and to avoid pruning just after the spring growth flush.

There should be a purpose for each cut, as each cut into a tree can change the growth of the tree for many years to come. Improper or careless pruning can cause damage over the life of the tree. It is important to know where and how to make cuts before beginning the process.

When a tree branch is cut, it compartmentalizes the wound to protect itself. A small cut does less damage than a large cut. Waiting to prune a tree until it is mature can create the need for large cuts, which can threaten the life of the entire tree. Ongoing and regular maintenance is a must.

Call on a certified arborist to maintain your trees in optimal health. Arborists are specialists trained in the art and science of planting, caring for, and maintaining individual trees. They can identify and treat diseases before they spread to other trees. Find qualified professionals at the International Society of Aboriculture and the American Society of Consulting Arborists.

As the Climate Warms, Electricity Demand Shows a Regional Shift

/in , /by /pv magazineby Ryan Kennedy

Even though American spent more time at home in 2020 during the Covid-19 pandemic lockdown, retail residential sales of electricity per capita rose by only 1% per person, year-on-year from 2019 to 2020, said the Energy Department’s Energy Information Administration. The agency said that warmer weather in 2020, especially a particularly mild winter, increased electricity usage from air conditioning, but cut U.S. electricity usage for space heating during colder months.

EIA reported that from 1960 to 2010, per capita U.S. electricity use posted a 3% average annual increase. That trend slowed over the past decade due to warmer weather and energy efficiency upgrades. Since 2010, per capita residential electricity use has fallen 5% in the U.S.. That means 2020 represented an uptick in demand relative to the broader trend.

‘Code Red’: UN Scientists Warn of Worsening Global Warming

/in , , /by /AP Newsby Seth Borenstein

Earth is getting so hot that temperatures in about a decade will probably blow past a level of warming that world leaders have sought to prevent, according to a report released Monday that the United Nations called a “code red for humanity.”

“It’s just guaranteed that it’s going to get worse,” said report co-author Linda Mearns, a senior climate scientist at the U.S. National Center for Atmospheric Research. “Nowhere to run, nowhere to hide.”

Water Cutbacks Coming to Arizona

/in , , /by /Arizona Public Mediaby Christopher Conover

The “bathtub ring” at Lake Mead has become a familiar sight. The water level in the lake is the lowest it has been since the Hoover Dam, which created the lake, was built in the 1930s. Those low levels have been decades in the making.

“Back in around 2000, Lake Mead was pretty close to being full, but over the last 20 years-plus now we’ve just not had good hydrologic conditions. It will take years to recover from that, years of good conditions and unfortunately the climate models and projections don’t predict us getting cooler and they don’t predict us, let’s say, getting wetter,” said Dr. Sharon Megdal, University of Arizona professor and former board member for the Central Arizona Project.

Study Reveals Effects of Extreme Heat on Tens of Millions of Americans

/in , , /by

The summer of 2020 brought fear of Covid-19, social distancing – and heat-related health problems that affects tens of millions of Americans.

During those months, more than a quarter of the US population suffered from the effects of extreme heat, according to a study released this week. People reported health symptoms like nausea and cramps, as well as a decreased ability to focus, and the effects hit low-income households the hardest.

The study focuses on last summer but given the brutal heatwaves that have hit the US in 2021, especially in western states, it raises the prospect that the impact of extreme heat is highly likely to be worse this year.
