Frackers are burning millions of dollars worth of natural gas — releasing hazardous chemicals and greenhouse gases into the air, worsening climate change and creating health risks. A new study by researchers at the University of South California and San Francisco State University found that oil and gas operators in South Texas burned almost 160 billion cubic feet of natural gas — enough to power 2.5 million homes for a year — from 2012 to 2016. The study, published earlier this month in the journal Environmental Science and Technology, looked at 49 rural Texas counties that are part of or adjacent to the Eagle Ford Shale and identified almost 44,000 oil and gas flares, combustion stacks that
The largest organizations in the world, including corporations with global supply chains, financial institutions, and governments are increasingly cooperating with each other on climate change. The 2015 Paris Agreement was signed by 196 countries that shared the goal of keeping the increase in global average temperature well below 2 °C and limiting the increase to 1.5 °C, mitigating some of the worst risks of climate change. While much progress has been made on electricity generation—and last week oil company BP's CEO said that renewables will be the world's main source of energy by 2040—soon enough the largest contributors to greenhouse gas (GHG) emissions will be sectors like manufacturing, transportation, and agriculture.
Clean Energy Fuels Corp. announced an increased demand for renewable natural gas (RNG) from the refuse sector, particularly in California, where refuse trucks are fueled by the very solid waste they haul. The city of Fresno signed a two-year agreement with Clean Energy for renewable liquified natural gas (RLNG) to power approximately 140 refuse trucks with its Redeem brand RNG for an anticipated annual total of 1.6 million LNG gallons, the equivalent of just over 1 million GGEs. Redeem is the first commercially available RNG vehicle fuel. It is derived from capturing biogenic methane that is naturally sourced by the decomposition of dairy and landfill waste. Redeem enables at least 70 percent
"Getting an accurate picture of the environmental risks of pharmaceuticals around the world depends on the availability of data, which is limited," says Rik Oldenkamp, lead author of the article. "It's true that there are models, such as the ePiE model, which can give detailed predictions of pharmaceutical concentrations in the environment, but these are often only applicable to places where we already have a lot of information, such as rivers in Europe." The new model developed by the researchers, which builds on an existing model with a lower resolution, makes it possible to come up with worldwide predictions for individual ecoregions. For the two pharmaceuticals investigated in the study -- carbamazepine, an anti-epileptic drug, and ciprofloxacin, an antibiotic -- the environmental risks were found to be 10 to 20 times higher in 2015 than in 1995. The increased human use of ciprofloxacin was found to have a particularly high impact globally.
Florida's coastal waters appear free from a devastating red tide bloom that began in October 2017. A Florida Fish and Wildlife Conservation Commission report released Wednesday says the toxic algae were no longer present in water samples collected anywhere in the state. The bloom caused respiratory irritations in people and killed vast numbers of sea turtles, manatees, dolphins and fish. Red tide is caused by an organism called Karenia brevis, which occurs naturally in the waters off Florida. NBC 6's Erika Glover looks into a hurricane's impact on red tide. In a Herald-Tribune report, University of South Florida red tide expert Robert Weisberg said currents that swept the organisms up from deep
MURPHY, TX -- The North Texas Municipal Water District's annual maintenance of the water distribution system will begin March 4 and run through April 1. The maintenance includes a temporary change in the way water is disinfected, the city said in a news release. Disinfection keeps drinking water free of harmful microorganisms, like parasites and viruses. "Normally, two chemicals are used in the disinfection process, chlorine and ammonia. During the month-long change, the water supplier uses only free chlorine to keep water disinfected as it travels through pipes. This is a common practice for as many as 40 percent of water providers which use the two-chemical process," the city added. The absence
WALLINGFORD, Vt. — The federal government says people have until April 1 to file any objections to a 15-year plan to increase the amount of young forest in the Green Mountain National Forest. The plan involves harvesting 15,000 acres of timber so that 5 to 10 per cent of the forest growth is up to nine years old. The project is intended to improve habitat for neo-tropical migrant songbirds and other wildlife species that thrive in young forests. U.S. Forest Service planner Jay Strand tells The Rutland Herald the plan was adjusted to decrease the amount of logging roads needed after the public comment period ended last year. He says people had concerns about soil and water quality. The timber
There's plenty of electricity out there to accommodate heavy-duty trucks and there's more political pressure than ever to move toward renewable energy. "We've been experimenting with natural gas, where you have to install compression stations costing hundreds of thousands of dollars," Susan Alt, vice president of public affairs for Volvo North America, told FreightWaves during the annual conference of NATSO, the truck stop owners' association, in Orlando earlier this month. It invested in Momentum Dynamics, a Philadelphia-based wireless charging company for commercial electric vehicles.
The Tyrannosaurus rex may have been one of the mightiest beasts to roam the ancient Earth -- though whether he was more of a scavenger than a predator has been the topic of much debate -- but Rex might have never existed at all if not for his much smaller predecessors.A newly discovered species of Tyrannosaur found in Utah is helping scientists to better understand how Tyrannosaurs arrived on the continent and spread across North America. It's an ancestor of the Rex, but unlike its much larger successor this new species, called Moros intrepidus, wasn't the top of its food chain.Researchers from North Carolina State University published a new paper in Communications Biology describing the discovery and the world the new species would have lived in. Intrepidus lived in a time where larger bipedal predators like allosaurs ruled the land.The species was traced to the late Cretaceous period, long before the age of the Rex, and a time when it would have had to contend with much larger predators and prey. Intrepidus would only have been about the size of a modern day deer, between three and four feet tall at its hip, but it was still capable of holding its own."Moros was lightweight and exceptionally fast," Lindsay Zanno, lead author of the work, said in a statement. "These adaptations, together with advanced sensory capabilities, are the mark of a formidable predator. It could easily have run down prey, while avoiding confrontation with the top predators of the day."Gradually, over tens of millions of years, Tyrannosaurs took the top spot, with larger and larger species that grew to dominate the ancient Earth. Exactly when and how that change took place is something that paleontologists around the world are still figuring out, but new discoveries like this one bring us a little bit closer.
The final weekend of February will deliver a wild potpourri of weather as winter and spring do battle across the United States.
Business and city leaders, energy companies, electric utilities, farmers and others are all voicing concerns about proposed legislation in New Mexico that would require sweeping environmental reviews by state agencies for many projects. The bill, known as the Environmental Review Act, stalled in a House committee Friday as some lawmakers sought more information. The bill was initially drafted by an attorney for the conservation organization New Mexico Wilderness Alliance and has undergone numerous changes. Supporters say it would create a state framework similar to what the federal government has for reviewing proposed activities on lands it manages. Opponents say existing laws and permitting
Early Monday morning, neighbor Janice Lawson heard a loud attack like barking. The owners of a nearby llama farm found numerous llamas dead. After six llamas were killed this week at a farm with wounds that “appeared canine in nature,” Louisville Metro Animal Services issued a list of precautions to take to protect your pets and small children. The agency couldn't confirm whether a dog, a coyote or some other large canine was behind the attack, which occurred Monday morning near the Louisville Zoo. Residents in nearby Strathmoor Village said they frequently see coyotes in the area. Here are the tips: Background: Llamas mysteriously killed in a grisly attack near the Louisville Zoo Do not approach
Los Angeles' trees are suffering from neglect. Around 30 percent of trees on city streets and in public parks are in danger of dying within a decade due to disease, pests and more frequent drought conditions. That's according to a ew report from the Los Angeles City Controller's office calling for the city to take a more efficient approach to preserving its urban forest. At a news conference Thursday in Canoga Park, Los Angeles City Councilman Bob Blumenfield and City Controller Ron Galperin unveiled the report, which recommends the city's Urban Forestry Division map out an inventory of public trees and create a digital database to track maintenance. The goal is to better identify trees in need
In 2015, 21 young people sued the U.S. government for promoting the fossil fuel industry even when it was aware of the dangers of climate change. In Juliana v. United States, the youths accused the government of endangering their future well-being thereby violating the government's public trust responsibility and their constitutional rights. The U.S. government has repeatedly tried to stop this case from moving to trial. Courts, including the U.S. Supreme Court, have denied or refused to rule on government challenges. The case is currently before the U.S. Ninth Circuit Court of Appeals on yet another motion to dismiss. The suit centers on whether the government actively promoted the use of fossil
