Recycled water revives a flourishing ecosystem on the Santa Cruz River in Tucson

3/29/2022

 
For much of the past century, the Santa Cruz River flowed through Tucson only when rainstorms sent muddy runoff coursing down the riverbed. Most of the time, the Santa Cruz sat parched in its channel, looking like a big dry ditch beneath the overpasses. Then on a hot summer day in 2019, the water came. Released from a pipe, the treated wastewater poured onto the sand and flowed downstream. A transformation began. Ecologist Michael Bogan hadn’t planned to study the resurgence of the Santa Cruz when he pedaled his bike down to the riverbed that day to watch the water roll down the dry channel. But as he snapped photos, Bogan was astonished to see dragonflies and damselflies soaring past and laying eggs in the water.
“This is crazy,” he said he thought to himself. “This is the first day of this ecosystem and they’re already moving in.” - AZ Central

Gas Prices May Be Rising But You’re Still Not Paying for the True Cost of Driving

3/26/2022

 
But nonetheless, as politicians try to bring down the cost of gas, I want to take a moment to reflect on the true cost of driving. That cost includes not just the price of a vehicle and filling up the tank but also the costs that operating it impose on society, including pollution that drives climate change. Calculating the damage done by pollution and other factors such as traffic and accidents—what economists call externalities—is a fraught process, and economists don’t necessarily agree about all the variables. But one thing is true under any reasoned consideration: driving costs society much more than you’re paying to do it. - Yahoo / Time

Why geothermal energy is being viewed as a viable alternative to fossil fuels

3/26/2022

 
President Biden and the European Union on Friday announced new plans to enable Europe to become less dependent on Russian oil and gas. But for now, the Russian invasion has opened up much larger questions over our dependence on fossil fuels and the need to develop cleaner renewable energy. Science correspondent Miles O'Brien reports on how and why geothermal energy is attracting new interest. - PBS

Dr. Katharine Hayhoe - How to Talk to People Who Don’t Believe in Climate Change

3/25/2022

 
Note: This different GeoNews seems worth including.  Dr. Hayhoe has been a featured speaker at AGU, the yearly conference of ~25,000 geoscientists in San Francisco. 

​Climate Scientist Dr. Hayhoe talks about living in Texas, how the issue of climate change became Republican vs Democrat, which groups of Americans we need to target to make change, fossil fuel companies paying to spread disinformation, how to communicate with someone who doesn’t believe in climate change, and her new book "Saving Us: A Climate Scientist’s Case for Hope and Healing In A Divided World." - YouTube

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

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

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

Which Came First, the Eruption or the Landslide?

3/1/2022

 
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
