Arizona faces a reckoning over water

3/25/2022

 
The question now, as it has been since 1911 when the first big reservoir was completed to supply Phoenix with water, is one of longevity. Can this desert bounty be sustained for another 100 years, or even another 50? That question is more urgent and more relevant than ever. Climate change is disrupting the rules of the development game. Drought and extreme heat are emptying rivers and reservoirs, fallowing tens of thousands of acres of farmland, forcing thousands of homeowners to secure water from trucks and not their dead wells, and pushing Arizona ever closer to the precipice of peril.- HCN

As Lake Powell Hits Landmark Low, AZ Looks to a $1 Billion Investment and Mexican Seawater to Slake its Thirst

3/20/2022

 
During his last year in office, Gov. Doug Ducey is trying to create a legacy of water security in drought-stricken Arizona. But his most ambitious effort in that quest could end up being in Mexico. In his last state of the state speech in January, he proposed an investment of $1.16 billion over the next three years to make the state “more resilient to drought, secure a sustainable water future and allow for continued growth.” The goal, he said, is to “secure Arizona’s water future for the next 100 years.”- Inside Climate News

It’s 70° warmer than normal in eastern Antarctica. Scientists are flabbergasted.

3/18/2022

 
The coldest location on Earth has experienced an episode of warm weather this week unlike any ever observed, with temperatures over the eastern Antarctic ice sheet soaring 50 to 90° above normal. The warmth has smashed records and shocked scientists. “This event is completely unprecedented and upended our expectations about the Antarctic climate system,” said Jonathan Wille, a researcher studying polar meteorology at Université Grenoble Alpes in France, in an email. - Washington Post

Radical Plan to Make Earth's Deepest Hole Could Unleash Limitless Energy

3/16/2022

 
Since its launch in 2020, a pioneering energy company called Quaise has attracted some serious attention for its audacious goal of diving further into Earth's crust than anybody has dug before. Following the closure of first round venture capital funding, the MIT spin-off has now raised a total of US$63 million: a respectable start that could potentially make geothermal power accessible to more populations around the world. The company's vision for getting closer to the center of the Earth is to combine conventional drilling methods with a megawatt-power flashlight inspired by the kind of technology that could one day make nuclear fusion energy possible here to edit. - Science Alert

Microsoft heads up $34M investment in software platform to cut cargo ship emissions

3/16/2022

 
Hundreds of cargo ships already use Nautilus’ software system to monitor and optimize their voyages, according to the company. That includes vessels owned or operated by the French oil and gas giant TotalEnergies, Eastern Pacific Shipping and Emirates Shipping Line. So far, Nautilus clients have saved up to 12 percent on fuel costs per voyage, with the overall savings potential expected to reach as high as 30 percent. - Canary Media

No Breathing Easy for City Dwellers: Particulates

3/15/2022

 
Air pollution is the fourth leading risk factor for death around the world. But one type of pollutant is particularly harmful: fine particulate matter (PM2.5). These small, inhalable particles (less than 2.5 micrometers in diameter) result from direct emissions into the air, as well as interactions among other pollutants. PM2.5 is the leading cause of death among air pollutants, contributing to cardiovascular and respiratory disease and millions of premature deaths worldwide each year.  - NASA

The population debate: Are there too many people on the planet?

3/13/2022

 
In the once-seedy district of Soho, about 10 minutes’ walk from New Scientist‘s London offices, a pump, a plaque and a pub commemorate one of the greatest ever breakthroughs in human history: a decisive step made almost 200 years ago towards conquering infectious disease. Our current global health crisis is a reminder of how little we want to return to the days when deadly infections carried away most of us. Yet also in some way, advances back then were a first step on a path towards planetary perdition. The success against infectious disease, alongside other major developments, dramatically improved our survival and set humanity’s numbers soaring, from little more than 1.25 billion people back then to 7.7 billion now. Now, climate change, biodiversity loss, the degradation of the biosphere and, yes, coronavirus are forcing us to consider the legacy of that success. The pandemic is becoming the latest focus for an old, uniquely contentious question: are there just too many of us on the planet? - New Scientist

Earthworms have the potential to replace use of synthetic fertilisers

3/13/2022

 
Earthworms could have the potential to replace some high-cost mineral/synthetic fertilizers, new research suggests. Researchers at University College Dublin have unearth fresh insight into the soil dweller's importance for crops taking up nutrients. The findings suggest a shortcut in the soil nitrogen cycle not previously recognized in which earthworms, when they are active, rapidly enrich soil and plants through nitrogen excreted in their mucus. The role of soil animals such as earthworms in nutrient cycling is traditionally seen as beneficial but indirect, slow and cumulative.- Phys.org

Lead from gasoline blunted the IQ of about half the U.S. population, study says

3/8/2022

 
Exposure to leaded gasoline lowered the IQ of about half the population of the United States, a new study estimates. The peer-reviewed study, published Monday in the journal Proceedings of the National Academy of Sciences, focuses on people born before 1996 — the year the U.S. banned gas containing lead. Overall, the researchers from Florida State University and Duke University found, childhood lead exposure cost America an estimated 824 million points, or 2.6 points per person on average. Certain cohorts were more affected than others. For people born in the 1960s and the 1970s, when leaded gas consumption was skyrocketing, the IQ loss was estimated to be up to 6 points and for some, more than 7 points. Exposure to it came primarily from inhaling auto exhaust. - NBC News

Lake Powell is about to drop below a critical level never reached before: drought

3/6/2022

 
For the first time since it was filled more than 50 years ago, Lake Powell, the second-largest reservoir in the country, is projected to dip past a critical threshold, threatening water supplies and putting a key source of hydropower generation at heightened risk of being forced offline, as climate change-fueled drought continues to grip the Western US. The US Bureau of Reclamation told CNN it is currently anticipating water levels in Lake Powell to reach a significant elevation of 3,525 feet above sea level sometime between March 10 and 16. - CNN

Renewables make up nearly all of Texas’ new generating capacity.

3/6/2022

 
Texas' love affair with renewable energy is undeniable. But even after another banner year for clean energy in the state, a market redesign, fueled by political rhetoric from state leaders, could thwart future deployment, experts say. Wind and solar accounted for nearly all new generating capacity added to the Texas grid in 2021, according to newly released market data. S&P Global Market Intelligence notes that power plant operators added 8,139 MW of new generating capacity to the ERCOT market last year -- 42% came from wind and 40% from solar. Natural gas-fired additions made up 13% of the new capacity. Nationally, wind and solar made up a slightly smaller share of new generating capacity -- 41% and 36%, respectively -- of the 27,959 MW of capacity added. - Renewable Energy World

A Century of Oil & Gas Development Has Devastated the Ponca City Region of Northern Oklahoma

3/5/2022

 
When Earl “Trey” Howe III returned home here after four years of military service, the first thing he noticed was the smell. Howe grew up in and around Ponca City, the site of the Phillips 66 refinery, one of the oldest and largest crude oil refineries and tank farms in the country. The smell from the plant—a sulfur-rich odor somewhere between rotten eggs and freshly paved asphalt—was so constant, he’d never even noticed it. But now, it seemed to follow him everywhere. "Depending on which way the wind is blowing, I’ll get a stronger whiff on some days than others,” Howe, 51, the former chairman of the Ponca Tribe of Oklahoma, said. “It’s overpowering sometimes.” - Inside Climate News

SoCalGas faces $10-million fine for fighting climate action

3/3/2022

 
Shareholders of the nation’s largest natural gas utility could be forced to pay nearly $10 million after using customer money to fight public policies that could slow the climate crisis. California officials are poised to levy the fine on Southern California Gas Co., which sells natural gas to millions of homes and businesses for heating and cooking, and to power plant operators for electricity generation. The fossil fuel is a major source of the heat-trapping carbon emissions that have caused worsening heat waves, wildfires, droughts and floods, and that are driving many species to extinction. SoCalGas has engaged in a sweeping campaign to block clean energy measures that threaten its business model, including local bans on gas hookups in new housing and statewide efforts to encourage construction of all-electric homes. - LA Times

Satellites have located the world’s methane ‘ultra-emitters’

3/1/2022

 
A small number of “ultra-emitters” of methane from oil and gas production contribute as much as 12 percent of methane emissions from oil and gas production every year to the atmosphere every year — and now scientists know where many of these leaks are. Analyses of satellite images from 2019 and 2020 reveal that a majority of the 1,800 biggest methane sources in the study come from six major oil- and gas-producing countries: Turkmenistan led the pack, followed by Russia, the United States, Iran, Kazakhstan and Algeria. Plugging those leaks would not only be a boon to the planet, but also could save those countries billions in U.S. dollars, climate scientist Thomas Lauvaux of the University of Paris-Saclay and colleagues report in the Feb. 4 Science. - Science News

eos.org/articles/which-came-first-the-eruption-or-the-landslideOn 22 December 2018, an eruption rocked Indonesia. Anak Krakatau, a volcano that sits in the Sunda Strait between the islands of Java and Sumatra, let loose. The eruption was accompanied by a massive landslide that triggered a tsunami and inundated nearby coastlines. A rock concert was interrupted when a wave crashed through the tent and swept the band off the stage. All told, more than 400 people died, around 14,000 were injured, and 33,000 were displaced. - EOS

Climate change: IPCC report warns of ‘irreversible’ impacts of global warming

2/28/2022

 
Many of the impacts of global warming are now simply "irreversible" according to the UN's latest assessment. But the authors of a new report say that there is still a brief window of time to avoid the very worst. The Intergovernmental Panel on Climate Change says that humans and nature are being pushed beyond their abilities to adapt. Over 40% of the world's population are "highly vulnerable" to climate, the sombre study finds. But there's hope that if the rise in temperatures is kept below 1.5C, it would reduce projected losses. - BBC

Hawaii relies on Russian oil — but clean energy could change that

2/28/2022

 
Russia invaded Ukraine, global oil prices spiked, and one U.S. state in particular will feel the crunch. Hawaii imports all of its oil, much of it from Russia itself. As the U.S. Energy Information Administration succinctly notes, ​“Isolated by the Pacific Ocean, Hawaii is the most petroleum-dependent U.S. state.” And while gasoline prices are rising everywhere, Hawaii is unique among the states in how much it depends on oil for electricity. The geopolitical strife in Eastern Europe catches Hawaii at an awkward moment of transition from fossil-fueled electricity to clean energy. - Canary Media

Small Earthquake Swarm Detected Near Roosevelt, Arizona: Feb. 25, 2022

2/28/2022

 
​Beginning February 12 of this year, a small swarm of earthquakes rattled the southern side of Theodore Roosevelt Lake. Although earthquakes are rare in southern Arizona, the area surrounding Roosevelt, AZ has experienced many historical earthquakes. Beginning in 2008, the Arizona Geological Survey began a statewide effort to monitor earthquakes using 8 broadband seismometers.  In 2017, 6 new stations were installed, including one near Roosevelt, Arizona, and two additional stations were added to the seismic network in 2018. With increasing station coverage, more of Arizona’s smaller earthquakes are being detected and better located. The latest swarm detected near Roosevelt Lake included 3 events (summary table below) with M 2.5 or greater and 10s of M1.0-1.5s that were too small to be located accurately. - AZ Geologic Survey

Road salt triggering 'massive' harm to US lakes, contaminating drinking water

2/27/2022

 
Five years ago, Hague was part of the problem. Each winter, more than 6 feet of snow fell on the upstate New York town nestled between scenic Lake George and the Pharaoh Lake Wilderness Area. Each year, the highway department dumped as much as 2,200 tons of rock salt onto 110 miles of road – nearly 2 pounds of salt for every square yard of road. And Hague is just one of more than a dozen communities that dot Lake George’s banks. Their combined use of road salt has increased the lake’s salinity nearly threefold over the past several decades, according to research by the nonprofit Fund for Lake George. The lake’s salt levels are now more than 30 times higher than more isolated lakes in the Adirondack Mountains, the group found. - USA Today

A major Atlantic current is at a critical transition point

2/26/2022

 
An analysis published in the journal Nature Climate Change in August found that the larger system that the Gulf Stream is part of, called the Atlantic Meridional Overturning Circulation (AMOC), is approaching a tipping point. Over the last century, this ocean circulation system has “moved closer to a critical threshold, where it may abruptly shift from the current, strong circulation mode to a much weaker one,” says study author Niklas Boers, a climate researcher at the Potsdam Institute for Climate Impact Research in Germany. Should the AMOC weaken substantially, it could bring intense cold and stronger storms to Europe, raise sea levels across the northeast coast of North America, and disrupt the flow of vital nutrients that phytoplankton, marine algae that make up the foundation of the aquatic food web, need to grow in the North Atlantic.- PBS

Duke may offer some EV customers 'all you can charge' for just $19.99/month

2/26/2022

 
Duke Energy has proposed an electric vehicle (EV) charging program that could allow some residential customers in North Carolina to charge a vehicle for a fixed monthly fee as low as $19.99. In exchange, the customer would allow Duke to manage the vehicle's charging, in order to avoid grid stress and higher costs. The utility is trying to provide a "seamless customer experience and an ecosystem of EV products," while also avoiding costly grid upgrades necessary to meet rising peak demand, Duke Vice President of Rate Design and Strategic Solutions Lon Huber said. The proposed pilot is "all you can charge," said Huber, though some limitations apply. - Utility Dive

Tranquil Valley’s Triumph Over Coal Shows Hurdles for Industry

2/25/2022

 
In the Bylong Valley in the verdant hills of southeastern Australia, a community’s victory over a planned coal mine shows the rising opposition that’s stalling new supply of the fuel and pushing prices higher. For campaigners in this pastoral countryside adjacent to a world heritage site, a decision this month by the High Court of Australia was the culmination of a years-long legal battle against a global corporate giant. For the loser, Korea Electric Power Corp., and for the coal industry as a whole, it was just the latest blow as sentiment hardens against the most-polluting fossil fuel. - Apple News (Bloomberg) or Mining Weekly
