Trump Administration Finalizes Coal Plant Pollution Rollback

8/31/2020

 
The Trump administration finalized its weakening of a rule aimed at reducing polluted wastewater from coal-burning power plants that has contaminated streams, lakes and underground aquifers. The change will allow utilities to use cheaper technologies and take longer to comply with pollution reduction guidelines that are less stringent than what the agency originally adopted in 2015. It's the latest in a string of regulatory rollbacks for coal power under Trump — actions that have failed to turn around the industry's decline amid competition from cheap natural gas and renewable energy. - ABC News

Cliff Collapse Reveals 313-million-year-old Fossil Footprints in Grand Canyon

8/29/2020

 
Paleontological research has confirmed a series of recently discovered fossils tracks are the oldest recorded tracks of their kind to date within Grand Canyon National Park. In 2016, Norwegian geology professor, Allan Krill, was hiking with his students when he made a surprising discovery. Lying next to the trail, in plain view of the many hikers, was a boulder containing conspicuous fossil footprints. Krill was intrigued, and he sent a photo to his colleague, Stephen Rowland, a paleontologist at the University of Nevada Las Vegas. - National Park Service

Mauritius: Anger and Questions as 17 Dead Dolphins Wash Ashore

8/29/2020

 
At least 17 dead dolphins have been found on the coast of Mauritius, prompting debates about whether a recent oil spill was to blame. Environmental campaigners say the deaths were either caused by the oil spill from a Japanese-owned ship or by authorities sinking part of the vessel. But the fisheries minister said "at first glance" the deaths appeared to be unconnected to the spill. He said at least two of the dolphins had shark bites.

Exxon Mobil Dropped from the Dow After Nearly a Century

8/25/2020

 
Energy giant Exxon Mobil joined the Dow 92 years ago as Standard Oil of New Jersey, and it's the oldest member of the index.  Exxon's market value has sunk to $175 billion. The company has been plagued in part by claims that it deliberately concealed the damage that the oil it has long extracted and refined into gasoline was doing to the planet. - CBS News

Here's How Much the US could Save if 25% of Vehicles were Electric

8/21/2020

 
A chemistry-climate computer model used data from tailpipe emissions to see how they influence atmospheric chemistry, and then combined this data with another set from the EPA showing how air quality affects health. When the computers ran the calculations, the result was staggering: The US would save $17 billion a year. That's not a one-time savings, but an annual figure. - CNET

Stroke Deaths Rise, Life Expectancy Falls with Polluted Air

8/21/2020

 
Regions with a high level of fine-grained air pollutants have shorter life expectancies and an increased rate of death from a stroke, according to new research. The study, which surveyed counties across the United States, also found a link between poor air quality and higher levels of poverty and reduced access to affordable healthcare. - EOS

Farmers Can Fight Climate Change, Make Agriculture More Sustainable

8/18/2020

 
Climate change is forcing farmers to make adjustments to ensure their crops can withstand evolving weather conditions. At the same time, many aspects of agriculture from tilling to raising livestock contribute to increased levels of carbon in the atmosphere, which exacerbates global warming.  But there's a movement afoot that not only could improve the business of farming but also help fields pull more carbon out of the atmosphere. It's called regenerative farming, and it emphasizes taking steps to cultivate stronger, healthier soil. - CBC

Trump Administration Completes Climate Dismantling with Methane Rollback

8/18/2020

 
EPA Administrator Andrew Wheeler announced the final rollback of Obama-era methane rules, marking the culmination of a 3 ½-year struggle by the Trump administration to undo emissions rules established at the end of President Obama's second term. That removal came despite their being supported by a significant segment of the oil and gas industry. - Scientific American

US Coal Power Generation Plummets 30% in 2020, EIA Says

8/18/2020

 
U.S. coal power generation plunged by 30% in the 1st half of 2020 off an already-depressed base, shoved out by natural gas and renewables amid low energy prices linked to the COVID-19 pandemic, according to new figures from the EIA.  Since peaking in '07, U.S. coal consumption has been on the decline, but the decline has been getting steeper and 2020 looks set to be an unprecedentedly terrible year for the sector. - GTM

Trump's Methane Rollback That Big Oil Doesn't Want

8/13/2020

 
Despite opposition from the oil and gas industry it aims to help, the Trump administration is rolling back an Obama-era rule designed to reduce climate-warming methane emissions.  Methane, the main ingredient in natural gas, when released before it burns, say from a leaky valve at a drilling site, is far more potent than carbon dioxide.  The oil and gas industry is the largest source of methane emissions in the United States. - NPR Link

If cost trends for renewables continue, 62% of China’s electricity could come from non-fossil sources by 2030 at a cost that is 11% lower than achieved through a business-as-usual approach. Further, China’s power sector could cut half of its 2015 carbon emissions at a cost about 6% lower compared to business-as-usual conditions. - Nature Communications Link
