Droughts and fires affecting Western U.S. air quality

New study tracks increase in summertime haze in Colorado wilderness

Longer and hotter droughts and wildfires are polluting the once clear blue skies of the high country in the West, according to new research from the University of Utah.

The study, published this week in the journal Environmental Research Letters, found a link between the severity of drought in the Intermountain West and summertime air quality. Climate projections suggest that drought and wildfire risk will continue to increase in coming decades.

“If you take that into the future, we’re going to see significant hazing of the West,” said University of Utah atmospheric scientist Gannet Hallar. Continue reading “Droughts and fires affecting Western U.S. air quality”

Wet spring and summer help avert worst of water shortages for now

Staff Report

FRISCO — Water storage in Lake Powell peaked on July 14 this year and has started its annual seasonal decline that will continue until spring runoff starts early in 2016, according to an Aug. 18 update from the U.S. Bureau of Reclamation.

Feds spending $150 million per day and seek firefighting help from Canada, Australia and New Zealand

Staff Report

FRISCO — This year’s wildfire activity in the U.S. has surged to the highest level in 10 years, with the National Interagency Fire Center reporting that about 7.2 million acres have burned so far, and officials said they expect the wildfire season to intensify in the coming weeks.

The drought-stricken far West is hardest hit, with 16 large fires currently burning in Washington, 14 in California and 12 in Oregon. Forest Service Chief Tom Tidwell said federal agencies are currently spending about $150 million per day on fighting fires across the West. Continue reading “U.S. wildfires surge to 10-year high”

Dirty little secret: West’s ozone problem is growing

Proposed EPA standards would help bring relief to residents of fossil fuel development zones

Staff Report

FRISCO — The mythology of the American West includes standard notions of pristine vistas and clean air, but the reality is far different. Some parts of the region have a dirty little secret — air quality that, at times, is worse than places like L.A.

And for now, the problem is getting worse. Expanded drilling on public lands is resulting in emissions of more volatile organic compounds that form the chemical basis for ozone. Global warming won’t help either. By mid-century, ozone pollution will become much more widespread as temperatures rise, potentially leading to widespread plant damage, according to one recent study.

Proposed new EPA ozone standards could help, but only if there’s an active year-round monitoring regime in the region, a coalition of environmental groups said in their formal public comments on the proposed new standards. Continue reading “Dirty little secret: West’s ozone problem is growing”

Study: Small trees key to long-term forest survival

Forest treatments that focus on removing smaller trees may not be the best tool for western dry forests, according to new research by University of Wyoming scientists.

Study shows many treatments in western dry forests are misguided

By Bob Berwyn

FRISCO — Mid-elevation forests in the western U.S. have survived centuries of drought, wildfires and insect onslaughts by hedging their bets with a diversity of tree sizes, Wyoming researchers said after studying forest plots from the Pacific Northwest down to Arizona and New Mexico.

The research showed that the biggest threat to those forests is from insects and not wildfires. Historically abundant small trees enable those forests to rebound after tree-killing bugs move through. Continue reading “Study: Small trees key to long-term forest survival”

Will there be a ‘hostile takeover’ of western public lands?

New website offers glimpse of ongoing efforts to ‘de-federalize’ the West

Staff Report

FRISCO — On and off efforts to force the transfer of federally managed public western lands to individual states have grown beyond campaign rhetoric.

These days, there’s a semi-organized effort on the part of lawmakers in several western states to try and take over millions of acres of forests and rangelands. The history of the so-called Sagebrush Rebellion, with roots in the Reagan era, is outlined in detail on this University of Colorado website.

Climate: Wet West in July

Energetic monsoon brings moisture surplus to many areas

The big wet?

By Summit Voice

FRISCO — An energetic and widespread monsoon weather pattern brought above normal precipitation to much of the West in August, with a bullseye of moisture in southern Idaho, extending across western Wyoming, Montana, northeastern Utah and into northwestern Colorado. Some locations in the region saw up to 800 percent of average precipitation. Continue reading “Climate: Wet West in July”
