Fires Consuming Nearly Twice as Much Forest as They Did 20 Years Ago

9/1/2022

 
Wildfires are destroying nearly twice as much tree cover globally as they did in 2001, burning through an additional 7.4 million acres of forest annually, an area roughly the size of Belgium, a new analysis shows. Researchers at the World Resources Institute (WRI) found that fires account for a growing share of forest loss. While wildfires were responsible for around a fifth of global tree cover loss in 2001, they accounted for more than a third in 2021. Researchers say that climate change is driving more intense and widespread wildfires by fueling more extreme heat and deepening drought, which dries out forests. The analysis was based on a recent study, which found a “near-uniform” growth in fire-related tree loss across the globe, from the Amazon to Australia to Siberia. - Yale360

Reintroducing bison results in long-running and resilient increases in grassland diversity

9/1/2022

 
Large animals (megafauna) have cascading effects on populations, communities, and ecosystems. The magnitude of these effects is often unknown because native megafauna are missing from most ecosystems. We found that reintroducing bison—a formerly dominant megafauna and the national mammal of the United States—doubles plant diversity in a tallgrass prairie. These plant communities have few nonnative species and were resilient to an extreme drought. Domesticated megafauna (cattle), which have replaced native herbivores in many grasslands, produced less than half of this increase in plant species richness. Our results suggest that many grasslands in the Central Great Plains have substantially lower plant biodiversity than before widespread bison extirpation. Returning or “rewilding” native megafauna could help to restore grassland biodiversity. - PNAS

In 'aggressive' step toward clean energy, Hawaii is closing its only coal power plant

9/1/2022

 
Hawaii is getting ready to say goodbye to its only coal power plant on Sept. 1 as part of its "aggressive push to renewable energy," according to the state's top energy official. The state received its final shipment of coal last week to the AES Hawaii power plant, located on the western side of Oahu, and  s looking toward new solar and battery storage energy projects. "It's the first large fossil fuel power plant that we're retiring," said Scott Glenn, chief energy officer at Hawaii State Energy Office. "The rest of the country is also grappling with this and we don't have the tools that the rest of the country does. ... (As an island chain) we can't reach out to others for help. It's an important step for Hawaii, and I also think it's going to be something that other states look to."- USA Today

Lake Powell Still Shrinking

9/1/2022

 
The second-largest reservoir in the United States now stands at its lowest level since it was filled in the mid-1960s. The view from above is sobering. Lake Powell, a key component of the western U.S. water system, is currently filled to just 26 percent of capacity, its lowest point since 1967. On August 22, 2022, the water elevation of the lake surface was 3,533.3 feet, more than 166 feet below “full pool” (elevation 3,700 feet).- NASA Earth Observatory

California just ran on 100% renewable energy, but fossil fuels aren't fading away yet

9/1/2022

 
On a mild Sunday afternoon, California set a historic milestone in the quest for clean energy. The sun was shining, the wind was blowing and on May 8th, the state produced enough renewable electricity to meet 103% of consumer demand. That broke a record set a week earlier of 99.9%. Energy experts say the falling records are a sign of the remarkable progress that renewable energy has made. But that doesn't mean fossil fuels were out of the picture. Even as the record was broken, natural gas power plants were still running in California. - NPR

Misinformation is derailing renewable energy projects across the United States

9/1/2022

 
On a winter night in early 2016, Jeremy Kitson gathered in his buddy's large shed with some neighbors to plan their fight against a proposed wind farm in rural Van Wert County, Ohio. The project would be about a mile from his home. From the beginning, Kitson — who teaches physics and chemistry at the local high school — knew he didn't want the turbines anywhere near him. He had heard from folks who lived near another wind project about 10 miles away that the turbines were noisy and that they couldn't sleep. "There were so many people saying that it's horrible, you do not want to live under these things,'" Kitson says. - NPR

Mississippi’s Capital Loses Water as a Troubled System Faces a Fresh Crisis

9/1/2022

 
More than 150,000 people in Mississippi’s capital were without access to safe drinking water on Tuesday, forcing officials to tackle what they described as the “massively complicated task” of distributing bottled water and devising a plan to restore service without a firm sense of how long that would take. The water system in Jackson, the state’s largest city, has been in crisis for years, hobbled by aging and inadequate infrastructure and, many in the city argue, a failure to devote sufficient resources to fix it. Residents have long contended with disruptions in service and frequent boil-water notices, including one that had already been in effect for more than a month because of cloudiness in water samples. - NYTimes

Study finds washing effectively removes lead from vegetables grown in urban soil

9/1/2022

 
Urban gardens offer many benefits for individual health, communities, and ecosystems. They promote sustainable agriculture, reduce food transportation costs, and reduce water runoff. However, urban gardeners also face several challenges, one of which is dealing with contaminants like lead. Lead is a neurotoxin that can damage multiple organ systems. "It is incredibly important to know if urban gardeners are being exposed to lead when they consume their produce," says Sara Perl Egendorf, a researcher at Cornell University. - Phys.Org

Shorter showers or rip up your lawn?: Conserving water is mostly an outdoors job

9/1/2022

 
The Southwest’s megadrought has put the spotlight on water conservation, and experts agree it’s a crucial part of the solution. But what does conservation mean to the average Arizonan? Shorter showers? No more grass lawns? What really matters might surprise you. Let’s say you’re standing at the kitchen sink with an empty peanut butter jar. You want to put it in the recycling bin, but you need to rinse it out first. Is it worth the water? In our daily lives, there are many ways to save water, such as turning off the faucet when we brush our teeth or taking shorter showers. These are nice gestures, but to really save water, said Sarah Porter of the Kyl Center for Water Policy at Arizona State University’s Morrison Institute, we need to think bigger - Cronkite News

Arizona AG, governor candidates call for Saudi Arabian water leases investigation

9/1/2022

 
Democratic attorney general candidate Kris Mayes is calling to investigate and potentially cancel the leases the State Land Department signed with a Saudi Arabian company that is pumping from Phoenix's backup water supply in western Arizona.  Mayes is also calling for the Saudi Arabian company to pay the state approximately $38 million for using the water in La Paz County, which sits in a basin that could be tapped as a future water source for the Phoenix area.  Mayes says the lease should be put on hold while they are investigated because they potentially violate the Arizona Constitution in two ways: They could violate the gift clause as well as a clause that requires state land and its products to be appraised and offered at their true value.  - AZ Central

Driving Cleaner

9/1/2022

 
To reduce both climate-changing emissions and exposure to air pollution, the United States must greatly reduce tailpipe emissions from cars and trucks. This makes the transition to electric vehicles (EVs) vital to meeting targets for both climate and public health. Using fully electric vehicles in place of conventional gasoline- and diesel-powered vehicles enables the complete elimination of tailpipe emissions. While electric vehicles can eliminate tailpipe emissions, the total emissions from their use include emissions from two other sources: the electricity used to recharge EVs and the processes and materials used to manufacture them. Thus, the value of switching from gasoline and diesel cars and trucks to EVs will increase further as the electricity grid and manufacturing become cleaner. - UCS

Micro hydropower system for building applications, usable with solar

9/1/2022

 
apanese startup Yumes Frontier has developed a micro-hydroelectric power generation system that uses small amounts of water in factories, buildings, and water purification plants. “Our system was conceived to utilize unused water pipes and is aimed at reducing electricity bills in commercial and industrial buildings,” a company spokesperson told pv magazine. “The system can be used in different kinds of commercial and industrial buildings, provided a few conditions are met. For example, a minimum flow rate of 4L/s and a water drop from a height of more than 4 meters. And if these conditions are met, it may even be installed in residential buildings or houses. - PV Magazine

Solar ‘tax’ removed from Diablo Canyon extension proposal, advocates say

9/1/2022

 
Solar advocates said that a so-called "monthly tax" on rooftop solar customers that was included in a proposal to extend the life of a nuclear power plant in California has been removed from the legislation at the urging of industry supporters. The Solar Rights Alliance said that the authors of Senate Bill 846, Gov. Gavin Newsom's push to approve a $1.4 billion loan to keep the Diablo Canyon Power Plant running, clarified that the legislation "will not impose a solar tax on the solar energy produced and consumed" by solar customers. The Environmental Working Group also joined the last-minute push against a potential "nonbypassable solar tax of up to $60 a month" that the group attributed to utility interests.

Droughts hit cattle ranchers hard – and that could make beef more expensive

9/1/2022

 
Supermarket shoppers are seeing something unusual these days: discounts in the meat department. Steak prices have fallen in each of the last three months even as the cost of chicken, pork and most other groceries has gone up. But bargains in the butcher case are likely to be temporary. Severe drought is forcing some cattle ranchers to slaughter livestock early. That's producing a glut of beef in the short term, but it's also likely to lead to higher prices in the future. According to the U.S. Department of Agriculture, 60% of the nation's cattle are affected by drought, including Brady Blackett's herd of angus cattle, which graze in the high desert of south central Utah. - NPR

Foot floating in a Yellowstone hot spring leaves more questions than answers

8/21/2022

 
A foot found floating in a hot spring at Yellowstone National Park has been linked to a July 31 death. On Aug. 16, a park employee found the foot, still encased in a shoe, in Abyss Pool, one of the deepest hot springs in Yellowstone. In a statement today (Aug. 19), authorities said that the foot is linked to an incident involving a single individual on the morning of July 31 and that they do not suspect foul play. They did not elaborate on why they do not suspect foul play, nor did they identify the person who died. An investigation is ongoing. - LiveScience

Climate change’s impact intensifies as U.S. prepares to take action

8/21/2022

 
For residents of the Norwegian archipelago of Svalbard, the United States’ recent success in clinching a major piece of climate change legislation may feel like too little, too late. Over the past 40 years, as the world’s largest historical emitter of greenhouses gases repeatedly failed to take significant action on the climate, the region surrounding Svalbard has warmed at least four times as fast as the global average, according to significant research published Thursday. The study suggests that warming in the Arctic is happening at a much faster rate than many scientists had expected. And while U.S. lawmakers this summer hashed out the details of a massive bill to speed their nation’s shift toward cleaner energy — the culmination of months of deliberations — the new findings were just the latest visceral reminder that the planet’s changing climate isn’t waiting around for human action. - Washington Post

Irreversible declines in freshwater storage projected in parts of Asia by 2060

8/21/2022

 
The Tibetan Plateau, known as the “water tower” of Asia, supplies freshwater for nearly 2 billion people who live downstream. New research led by scientists at Penn State, Tsinghua University and the University of Texas at Austin projects that climate change, under a scenario of weak climate policy, will cause irreversible declines in freshwater storage in the region, constituting a serious threat to the water supply for central Asia, Afghanistan, Northern India, Kashmir and Pakistan by the middle of the century. “The prognosis is not good,” said Michael Mann, distinguished professor of atmospheric science at Penn State. “In a ‘business as usual’ scenario, where we fail to meaningfully curtail fossil fuel burning in the decades ahead, we can expect a substantial — that is, nearly 100% loss — of water availability to downstream regions of the Tibetan Plateau. I was surprised at just how large the predicted decrease is even under a scenario of modest climate policy.” - Penn State

Researchers work to find new uses for red mud - caustic byproduct of aluminum production.

8/21/2022

 
Practical and glamorous, aluminium is prized for making products from kitchen foil and beverage cans to Tesla Roadsters and aircraft. But the silvery metal—abundant, cheap, lightweight, and corrosion resistant—has a dark side: red mud. This brownish red slurry, a caustic mishmash of metal- and silicon-rich oxides, often with a dash of radioactive and rare earth elements, is what's left after aluminum is extracted from ore. And it is piling up. Globally, some 3 billion tons of red mud are now stored in massive waste ponds or dried mounds, making it one of the most abundant industrial wastes on the planet. Aluminum plants generate an additional 150 million tons each year. Red mud has become trouble looking for a place to happen. In 2010, an earthen dam at one waste pond in Hungary gave way, unleashing a 2-meter-high wall of red mud that buried the town of Ajka, killing 10 people and giving 150 severe chemical burns. (See more on the dangers posed by waste dams.) Even when red mud remains contained, its extreme alkalinity can leach out, poison groundwater, and contaminate nearby rivers and ecosystems. - Science.org

DOE Finds Record Production and Job Growth in U.S. Wind Power Sector

8/21/2022

 
WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today released three reports showing that wind power remains one of America’s fastest growing energy sources and a generator of high-quality jobs. Wind power accounted for 32% of U.S. energy capacity growth in 2021, employs 120,000 Americans, and now provides enough energy to power 40 million American homes. The 2021 wind market reports show that the domestic expansion of wind power is proving to be an essential source of clean, cheap energy generation that supports President Biden’s goals of reaching 100% clean electricity by 2035 and a net zero economy by 2050. - Energy.gov

Seawater could provide nearly unlimited amounts of critical battery material

8/21/2022

 
Booming electric vehicle sales have spurred a growing demand for lithium. But the light metal, which is essential for making power-packed rechargeable batteries, isn't abundant. Now, researchers report a major step toward tapping a virtually limitless lithium supply: pulling it straight out of seawater. "This represents substantial progress" for the field, says Jang Wook Choi, a chemical engineer at Seoul National University who was not involved with the work. He adds that the approach might also prove useful for reclaiming lithium from used batteries. Lithium is prized for rechargeables because it stores more energy by weight than other battery materials. Manufacturers use more than 160,000 tons of the material every year, a number expected to grow nearly 10-fold over the next decade. But lithium supplies are limited and concentrated in a handful of countries, where the metal is either mined or extracted from briny water.- Science

Wind and Solar Are Saving Texans $20 Million a Day

8/21/2022

 
In a year of record-high prices for fossil fuels, as lawmakers consider new policies that can help fight inflation, renewable energy is already helping to shield Americans from steep jumps in their electricity bills. For example, in Texas, even as some observers have incorrectly blamed renewables for the state’s strained power grid, more than a third of electricity in the first half of 2022 came from wind and solar projects. Wind and solar have both set records already this year. High production from renewables and high fossil fuel prices together mean wind and solar are having an outsized impact on lowering energy costs. Based on benchmark natural gas prices, RMI estimates that, on average, wind and solar projects in Texas have avoided $20 million per day in fuel that otherwise would have been needed for fossil fuel-based power plants to meet electricity demand.- RMI

Swiss mountain pass will lose all glacier ice ‘in a few weeks’ for first time in centuries

8/21/2022

 
The thick layer of ice that has covered a Swiss mountain pass for centuries will have melted away completely within a few weeks, according to a local ski resort. After a dry winter, the summer heatwaves hitting Europe have been catastrophic for the Alpine glaciers, which have been melting at an accelerated rate. The pass between Scex Rouge and Tsanfleuron has been iced over since at least the Roman era. But as both glaciers have retreated, the bare rock of the ridge between the two is beginning to emerge – and will be completely ice-free before the summer is out. - The Guardian

Strip Mining Worsened the Severity of Deadly Kentucky Floods, Say Former Mining Regulators. They Are Calling for an Investigation

8/21/2022

 
Two former state and federal mining regulators say state and federal authorities should investigate the role strip mining played in last week’s devastating and deadly flooding in eastern Kentucky and the condition of the mines after the torrential rainfall. The Kentucky counties, and areas of West Virginia and Virginia, flooded by torrential rains have for decades been heavily logged and strip-mined for coal—land-use practices that dramatically alter the landscape and contribute to flooding. The recent flooding has killed at least 37 people. With strip mining, trees are the first to go. Then, hundreds of feet of rock may be  blasted away from the tops or sides of mountains to get at underground seams of coal. - Inside Climate News

Arctic Warming Is Happening Faster Than Described, Analysis Shows

8/21/2022

 
The rapid warming of the Arctic, a definitive sign of climate change, is occurring even faster than previously described, researchers in Finland said Thursday. Over the past four decades the region has been heating up four times faster than the global average, not the two to three times that has commonly been reported. And some parts of the region, notably the Barents Sea north of Norway and Russia, are warming up to seven times faster, they said. One result of rapid Arctic warming is faster melting of the Greenland ice sheet, which adds to sea-level rise. But the impacts extend far beyond the Arctic, reaching down to influence weather like extreme rainfall and heat waves in North America and elsewhere. By altering the temperature difference between the North Pole and the Equator, the warming Arctic appears to have affected storm tracks and wind speed in North America. - NYTimes
