As Oceans Warm, Marine Life Faces Extinction Levels That Rival Dinosaurs' End

5/1/2022

 
By 2100, we could be heading towards a loss of life in our oceans that rivals some of the largest extinction events in Earth's history if we don't continue to tackle the climate catastrophe, new modeling warns. But "it is not too late to enact the reductions in greenhouse gas emissions needed to avoid a major extinction event," Princeton geoscientists Justin Penn and Curtis Deutsch explain in their paper. Using modeling calibrated against ancient fossil records, they predict the consequences of runaway climate change on marine animals and provide a plausible explanation for an enduring ocean mystery in the process. - Science Alert

A Quiet Revolution: Southwest Cities Learn to Thrive Amid Drought

4/29/2022

 
In the rolling hills around San Diego and its suburbs, the rumble of bulldozers and the whine of power saws fill the air as a slew of new homes and apartments rise up. The region is booming, its population growing at a rate of about 1 percent a year. This, in spite of the fact that Southern California, along with much of the West, is in the midst of what experts call a megadrought that some believe may not be a temporary, one-off occurrence, but a recurring event or even a climate change-driven permanent “aridification” of the West. The drought is so bad that last year federal officials ordered cuts to water provided to the region by the Colorado River for the first time in history. Water officials in San Diego, though, say they are not worried. “We have sufficient supplies now and in the future,” said Sandra Kerl, general manager of the San Diego Water Authority. “We recently did a stress test, and we are good until 2045” and even beyond. - Yale Environment350

Powell’s looming power problem

4/12/2022

 
Over the last two decades, climate change-induced drought and increasing water demand have depleted Lake Powell substantially: It is now less than one-fourth full. As water levels drop, so, too, does the potential energy of the falling water. That, in turn, lowers the turbines’ generating capacity and power output. In the 1990s, the dam produced as much as 7,000 gigawatt hours per year, enough to power nearly 600,000 homes. Last year, it was down to just 3,000 gigawatt hours. - HCN

The future cost of climate inaction? $2 trillion a year, says the government

4/7/2022

 
With time running out to head off the worst damage from climate change, the United States government is starting to quantify the cost of inaction – for taxpayers. The White House Office of Management and Budget (OMB) released the first ever accounting of how unchecked global warming would impact the federal budget, looking at its potential to dampen the economy as a whole, and balloon the costs of climate-related programs over time. "The fiscal risk of climate change is immense," wrote Candace Vahlsing, Associate Director for Climate, Energy, Environment, and Science at OMB, and Danny Yagan, Chief Economist at OMB, in a blog post discussing the analysis. -NPR

SRP’s baffling, costly natural gas expansion (Op-Ed)

4/7/2022

 
The U.S. power generation market has changed dramatically over the past five years. Natural gas has been bleeding market share to cheaper sources of electricity, which include solar, wind, and even nuclear. At roughly $5 per MMbtu, the price of natural gas today is more than double what it was just two years ago. Even at half of that price, natural gas has been unable to compete with solar in the Southwest. - AZ Capitol Times

The Oldest Mummies in the World Are Rotting and Sprouting Mold

4/1/2022

 
Climate change is bringing rain and humidity to usually dry and arid Northern Chile, causing ancient mummies to decompose as they are exposed to increased moisture and the elements. The phenomenon puts some of the world’s oldest known mummies at risk of deteriorating after thousands of years of artificial and natural preservation. The mummies were created by the people of the Chinchorro culture, a fishing community who lived in what is now Chile and Southern Peru from 5,000 BC to 500 BC. They carefully prepared their dead by removing skin and organs and filling out the bodies with animal skins or clay and reeds. Some even had their original skin put back onto reshaped bodies, as if they were reupholstered for the afterlife. - Gizmodo

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

​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

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

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

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

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

Fossil Fuel Industry Emitting 70% More Methane Than Official Numbers Show

2/25/2022

 
The fossil fuel industry has a big methane problem, and we’re only just beginning to realize how serious it is. The IEA released a new analysis finding that methane emissions from energy production are being severely undercounted and are up to 70% higher than official estimates provided by countries around the world. While methane stays in the atmosphere for a much shorter time than carbon dioxide, it packs a real punch while it’s up there - about 80X more potent over a 20-year period. Reducing methane emissions as soon as possible is key to warding off the worst impacts of climate change. The oil and gas industry is responsible for a big chunk of methane emissions, from processes during production including venting and flaring—releasing excess gas into the atmosphere—as well as leaks (that can be substantial) along the supply chain.- Gizmodo

Fossil Fuel ‘Flares’ Excess Natural Gas - Burning Money & Bad for the Environment

2/25/2022

 
When fossil fuel companies flare fossil gas, they do more than burn natural gas. They burn money. Every year, U.S. oil and gas companies set fire to billions of cubic feet of natural gas and directly vent an additional unknown amount. These processes, known as flaring and venting, don’t just waste resources; they also pollute the atmosphere with hazardous, global-warming gases, such as methane. Companies argue that they flare and vent for safety and maintenance and because selling or reusing the gas is not financially feasible. The industry and its regulators even refer to this gas as “waste.” But experts say a valuable resource is being squandered because of weak regulations, ineffective tracking of flaring and venting, and a lack of economic incentives to capture and sell the gas.  - Inside Climate News

The digital world’s real-world impact on the environment

2/25/2022

 
Every office email, every social media “like,” every credit card transaction and telecommuter call still has to be processed by physical computers, real machines that use real energy and water and have real environmental impacts. Even cryptocurrency must be “mined” in an energy-intensive way. Thousands of servers, storage units and network devices stacked up in sprawling warehouses across the West - on the fringe of Phoenix, along the Columbia River, and even in Wyoming’s hinterland - suck juice from the grid to process millions of transactions. The electricity becomes equipment-straining heat, which must be shed using water or more electricity. Instead of seeking veins of gold or silver, cryptocurrency miners chase cheap energy — even setting up shop on oil and gas pads to utilize methane that otherwise would be flared — because more power use equals greater computing capacity, which equals higher profits.- HCN

‘Nuclear is just not part of any feasible strategy that could counter climate change.’

2/24/2022

 
The climate is running hot. Evolving knowledge of climate sensitivity and polar ice melt-rate makes clear that sea-level rise is ramping, along with destructive storm, storm surge, severe precipitation and flooding, not forgetting wildfire. With mounting concern and recognition over the speed and pace of the low carbon energy transition that’s needed, nuclear has been reframed as a partial response to the threat of global heating. But at the heart of this are questions about whether nuclear could help with the climate crisis, whether nuclear is economically viable, what are the consequences of nuclear accidents, what to do with the waste, and whether there’s a place for nuclear within the swiftly expanding renewable energy evolution. As key experts who have worked on the front-line of the nuclear issue, we’ve all involved at the highest governmental nuclear regulatory and radiation protection levels in the US, Germany, France and UK. In this context, we consider it our collective responsibility to comment on the main issue: Whether nuclear could play a significant role as a strategy against climate change. The central message, repeated again and again, that a new generation of nuclear will be clean, safe, smart and cheap, is fiction. The reality is nuclear is neither clean, safe or smart; but a very complex technology with the potential to cause significant harm. Nuclear isn’t cheap, but extremely costly. Perhaps most importantly nuclear is just not part of any feasible strategy that could counter climate change. To make a relevant contribution to global power generation, up to more than ten thousand new reactors would be required, depending on reactor design. - Nuclear Consulting Group

Climate data reveals a hotter, drier Arizona, with more extremes possible

John Loleit has kept a watchful eye on the towering saguaros and well-worn trails of the McDowell Sonoran Preserve for 22 years. Loleit, the natural resources coordinator for Scottsdale, takes to the wilds of the 47-square-mile park almost every day in all weather, mending fences, leading hikes and training park employees and volunteers, encouraging visitors to look for clues about what’s happening to the environment around them from year to year. “I tell folks, pick out a saguaro cactus, and that’s your saguaro. Every time you pass by, just take a look at it. Look at the main trunk,” Loleit said. “Over a period of time, are you seeing that it’s thin, and its ribs are shrinking and losing water or then they’re opening up and fat if we’ve got rain?” - Cronkite News

A new tundra, engineered by beavers

2/18/2022

 
Beavers, once seldom seen in northwest Alaska, started appearing more frequently in the ’80s and ’90s. Pastor Lance Kramer (Inupiaq) traps beavers today, mostly for making fur hats. He recently asked an elder about the area’s first sightings. “They saw this thing on the tundra, and it looked like a wolverine, but it was a really long beaver,” Kramer said. “(It) had walked so far on the tundra to get up this way that it wore out the bottom of its tail.”  Now the animals — and their ponds, dams and lodges — are everywhere. Using satellite images of the Kotzebue area, scientists found that the number of beaver dams surged from two in 2002 to 98 in 2019, a 5,000% jump. And it’s not just Kotzebue: Beaver ponds doubled regionally since 2000, with 12,000 in northwestern Alaska now. Beavers, dubbed “ecosystem engineers” because of how they flood their surroundings, are transforming the tundra. - HCN

Study: Accusations of 'greenwashing' by big oil companies are well-founded

2/17/2022

 
Four major oil companies aren't taking concrete steps to live up to their pledges to transition to clean energy, new research has found. The study, published Wednesday in the journal PLOS One, found that Chevron, ExxonMobil, BP and Shell used terms like "climate," "low-carbon" and "transition" more frequently in recent annual reports and devised strategies around decarbonization. But their actions on clean energy were mostly pledges and the companies remain financially reliant on fossil fuels. "We thus conclude that the transition to clean energy business models is not occurring, since the magnitude of investments and actions does not match discourse," the researchers at Tohoku University and Kyoto University in Japan said. The four major oil companies the study focuses on account for more than 10% of global carbon emissions since 1965, the researchers said. - NPR
