NEW YORK — A long-delayed report from the Environmental Protection Agency finds that requiring ethanol made from corn and soybeans to be part of the nation's gas supply is causing serious environmental harm.

Federal law requires the EPA to assess the environmental impact of the fuel standard every three years, but the new report, issued in July, was four years overdue. According to David DeGennaro with the National Wildlife Federation, the report documents millions of acres of wildlife habitat lost to ethanol crop production, increased nutrient pollution in waterways and air emissions and side effects worse than the gasoline the ethanol is replacing.

"In finding that the Renewable Fuel Standard is having negative consequences to a whole suite of environmental indicators,” DeGennaro said, “the report is a red flag warning us that we need to reconsider the mandate's scope and its focus on first-generation fuels made from food crops.”

President Donald Trump and senators from agricultural states are urging the EPA to allow an increase in the mandated ethanol content of gasoline.

The EPA report indicates that biofuels have a negative impact on air quality. Johnathan Lewis, senior counsel for climate policy with the Clean Air Task Force, said ethanol from corn in particular is linked to increased emissions of nitrogen oxides, or nox.

"Nox contributes to ozone formation when it mixes with volatile organic compounds in the presence of sunlight,” Lewis said. “So in most areas of the country, an increase in nox emissions can result in increased ozone formation."

Ground-level ozone, the main ingredient of smog, is a major cause of asthma and other respiratory illness.

Right now, most gas is E-10, containing 10 percent ethanol. But despite the EPA report's findings, DeGenarro pointed out there is political pressure to raise the biofuels mandate of the Renewable Fuel Standard.

"Just last week, President Trump told an audience in Iowa that he was "very close" to having EPA issue a waiver to the Clean Air Act to allow year-round sale of E-15,” DeGenarro said.

In March, a bill called the GREENER Fuels Act was introduced in Congress to reduce the use of corn ethanol and cap the content in gasoline at less than 10 percent.

CASPER, Wyo. - A strong majority of voters across party lines say they want national rules similar to those passed in Wyoming to reduce methane pollution from oil and gas production, according to a new national poll.

Jon Goldstein, senior director of regulatory and legislative affairs for the Environmental Defense Fund, the group behind the survey, said nearly two-thirds of voters support stronger methane rules if they lead to jobs in the methane mitigation industry.

"Wyoming is one of the leading states in the nation for clusters of these methane-mitigation industry jobs," he said, "factory jobs building the pieces of equipment that are used out in the oil and gas field; the inspectors that go out with infrared cameras and find and fix the leaks."

The poll comes as the Environmental Protection Agency soon is expected to release nationwide methane rules for the oil and gas industry. Industry groups have pushed back on protections that would include low-producing wells, citing costs, but the survey found seven out of 10 voters want rules that cover all wells, regardless of size.

Goldstein argued that national rules are necessary because air pollution doesn't stop at the state line. He added that technologies to capture lost natural gas have proved to be highly cost-effective.

"They're not free, but we are talking about pennies on the dollar," he said. "And with natural-gas prices going up again, it really makes sense to be capturing all of the methane we can. You know, this is natural gas, at the end of the day."

Methane is more than 80 times more powerful at trapping heat in the atmosphere than carbon, and at least 60% of methane emissions are the result of human activities. Goldstein said national protections would be a big step in addressing climate change.

"Methane is responsible for about a quarter of the warming that we're already experiencing," he said, "and particularly addressing methane from the oil and gas industry is really the 'low-hanging fruit' of ensuring that the country bends the curve on climate as quickly as possible."

DENVER -- Few people spend as much time in the wilderness and outdoors as hunters and anglers, and a new report aims to be a springboard to bring those conservationists and their knowledge into discussions of combating climate change.

The report, titled A Hunter's and Angler's Guide to Climate Change, touches on a variety of landscapes throughout the country used by sportsmen and women that face environmental threats. Among them are the country's forests and rivers.

Aaron Kindle, director of sporting advocacy at the National Wildlife Federation and the report's author, said in Colorado, heat waves, droughts, and forest fires are hurting outdoor recreation in the state.

"If your elk hunt is canceled because the unit that you were going to hunt in is burning down, that's clearly an impact on the ability to hunt," Kindle remarked. "We saw historic closures this year in Colorado. Many rivers closed because of too hot of temperatures for trout, so those are the kinds of things we're seeing, that are really meaning, our ability to hunt and fish is under threat."

Colorado had its first 200,000-acre forest fire in 2020. The report showed natural infrastructure can offer some level of protection for these areas. Wetlands, forests and floodplains in particular can prevent flooding and help purify water.

Kindle said some immediate actions hunters and anglers can take to start contributing to the fight against climate change include taking part in reforestation efforts. But a big part of finding environmental solutions is by advocating for resources on the state and federal level.

"We are a community of storytellers," Kindle reflected. "We talk about the hunt. We talk about fishing. We talk about the seasons and how they've changed. And hunters and anglers have such a crucial narrative that would help shape those pieces of legislation into a better form."

Among the federal support named in the report is the REPLANT Act, which would quadruple investments in reforestation in national forests. It also suggested relaunching the Civilian Conservation Corps, a 1930s public-works program, but with a focus on addressing climate change.

STATE COLLEGE, Pa. -- October is usually the best time of year to see the bright, changing leaf colors that ring in autumn in Pennsylvania, but researchers say the wet, warm weather of the last few months may result in muted fall foliage.

When the days get shorter and the temperature drops, chlorophyll, which creates leaves' green pigment, breaks down, while anthocyanin, which causes the red coloring, is produced. The ideal conditions for this are moist summers and drier fall seasons.

Pennsylvania saw one of the wettest summers on record this year and an unseasonably warm fall so far, which has led to a delay in the changing leaf colors.

Marc Abrams, professor of forest ecology and tree physiology at Penn State University, said when fall foliage is late, it can lead to a shorter peak period for viewing.

"We might have a sudden frost come about at any time, and when that hits the green or just slightly changing leaves, it will turn them brown rather quickly," Abrams explained. "All those things could either truncate or be a further negative factor for fall colors this year."

This summer was the seventh hottest and 11th wettest on record for Pennsylvania, according to the National Oceanic and Atmospheric Administration. Abrams pointed out in central Pennsylvania, peak coloration is occurring about half a week later than it did about 40 years ago.

Among the types of trees in Pennsylvania appearing most impacted by the extreme weather are sugar and red maple, both major color-producing species, suffering from a leaf fungus. Even though the foliage has been disappointing so far, Abrams is holding out hope colder temperatures in the next few weeks will create stunning landscape views.

"Fall color can be really resilient and actually overcome a lot of these negative factors," Abrams noted. "I still encourage people to get out there. Keep an eye on when things are starting to change in your area and take nice drives into wooded areas and try to seek out these really good colors."

The Department of Conservation and Natural Resources also offers weekly statewide reports showing where and when Pennsylvania leaves are at their peak.
