Without regs, emissions could triple by 2050
FRISCO — With the EPA set to decide in May whether aircraft carbon pollution endangers public health or welfare, the battle over airline industry emissions in heating up.
Both the EPA and the airline industry have been dragging their feet for years, refusing to address one of the fastest growing sources of greenhouse gas pollutants. This week, six major green groups called on the EPA and the Federal Aviation Administration to move quickly to set emission standards to curb greenhouse gas pollution from the nation’s aircraft fleet.

FRISCO — U.S. airlines aren’t making much progress in reducing greenhouse gas emissions, according to a new report from the International Council on Clean Transportation. Despite some improvement by individual airlines, the analysis showed there was no net improvement in the fuel efficiency of U.S. domestic operations from 2012 to 2013.
The nonprofit organization also calculated that two of the most fuel efficient carriers — Alaska and Spirit — had the highest operating profit margins in 2013. Meanwhile less-efficient carriers like Allegiant made profits while using old, polluting and less efficient aircraft. The study findings contradict airline industry arguments that fuel costs automatically push airlines to maximize efficiency. Continue reading

Kim Fenske tours Colorado’s only world heritage site
Long Dwelling, Mesa Verde National Park.
Story and photos by Kim Fenske
Arriving at the Mesa Verde National Park Visitor and Research Center ten miles east of Cortez in early evening, I worked with a ranger at the tour desk to build an itinerary at Colorado’s only World Heritage site. Despite the ranger’s doubts that I could meet the necessary schedule, I purchased tickets for the three possible tours at a cost less than a camping fee at developed campgrounds. The tours of both Wetherill Mesa in the southwest corner of the park, and Chapin Mesa in the southeast portion of the park, involved driving nearly a hundred miles during the day.
After paying the entry fee, I drove a few miles south to Morefield Campground and registered for two nights of camping at the campground store, open from mid-May through mid-October. The complex offers showers, laundry, internet, fuel, and basic camping supplies, more services than typical of my usual backcountry or primitive camping on national forest lands. After purchasing ice to defend against the ninety-degree heat of the day, I found a tent site conveniently located a short distance from the amenities. My primary criticism of the facilities is that new investment is overdue to update showers and restrooms in the campground. Continue reading

UK researchers say rerouting flight paths could cut warming effect

FRISCO — Chemtrail conspiracy theorists aside, researchers at the University of Reading (UK) say that airplanes could reduce their climate impact by choosing flight paths in areas where jet exhaust condensation trails are less likely to form and persist.
The study, published June 19 in the journal Environmental Research Letters, shows that aircraft contribute less to global warming by avoiding the places where the thinly shaped clouds, called contrails, are produced – even if that means flying further and emitting more carbon dioxide. Continue reading

Stargazing, an Easter Egg hunt and movie screenings all part of the festivities
FRISCO — Dinosaur National Monument, in northwestern Colorado, will celebrate National Park Week with a slew of special activities, including an Easter Egg hunt of the younger set (April 20), a birthday party of sorts for the monument’s famed stegosaurus statue, as well as a twilight tour and stargazing.
“National Park Week is a great time to get out and celebrate your parks. At Dinosaur National Monument, we are excited to welcome visitors from all over the world,” said acting superintendent Mark Foust.”We would especially like to welcome local residents who may not have come out to the monument recently. We are proud to be a part of the local communities and would love to see as many people as possible re-connect with the monument and take advantage of the free admission days to get out and enjoy the quarry area and the canyon country.” Continue reading
