Well density seen as key factor in decline of birds in Wyoming
Limiting the density of new oil and gas drilling rigs in Wyoming may not be enough to stem the decline of greater sage-grouse, according to scientists tracking populations of the imperiled bird.
Berween 1984 and 2008, populations declined by 2.5 percent annually, and the drop is clearly linked with oil and gas development, the new study from the USGS and Colorado State University found. The researchers used annual counts of males at breeding sites for their estimates, comparing those tallies to the the density of oil and gas wells and the area of disturbance associated with these wells.

‘The government will increasingly have its work cut out selling fracking to the UK public’
Support for fracking is at an all-time low in the UK, with nearly half the respondents in an annual poll expressing concerns about water quality.
The September 2016 survey found that there has been a significant drop in the level of support for shale gas extraction in the UK over the last 12 months, with levels of support now standing at just 37.3 percent whereas opposition to fracking in the UK now stands at 41 percent.
The University of Nottingham ‘Survey of Public Attitudes to Shale Gas Extraction in the UK’ has been running since March 2012. The survey has tracked changes in awareness of shale gas, and what the UK public believes to be the environmental impacts of its extraction and use, as well as its acceptability as an energy source.

Oil and gas exploration would have widespread effects on marine mammals
Conservation advocates have long been saying that blasting the Gulf of Mexico with seismic airguns to find more oil and gas beneath the seafloor would result in unacceptable harm to marine mammals and other marine life, and a new draft environmental study by the Bureau of Ocean Energy Management seems to confirm those concerns.
The study was completed under the terms of a court-ordered settlement of a lawsuit brought by environmental groups. It shows that the blasting would have widespread impacts on marine life, including injuries to endangered sperm whales and Bryde’s whales. The draft report outlines possible mitigation measures, including closure areas where seismic blasting would be banned, and reductions in the amount of activity permissible each year.

Civic groups brainstorm green policies at Vienna meeting
By Bob Berwyn
European environmental leaders this week called on the EU adopt an innovative mindset for dealing with climate and energy issues. Europe stands to gain from adopting progressive policies that create economic opportunities for businesses and improve life for citizens.
After laying the groundwork for utility scale solar development with an over-arching plan covering public lands, the Obama administration wants to take similar steps to foster offshore wind power. Last week, cabinet officials said their strategic vision for offshore wind energy includes reducing technical costs and risks to make investments more predictable.
The Department of Interior will take steps to make the regulatory process more predictable, transparent, efficient and informed by lessons learned from regulators in other countries. The Energy and Interior departments also committed to analyzing field data from operating offshore wind farms to asses impacts on marine life, turbine radar interference in to support future offshore wind siting and plan reviews.

Research to help shape efforts to reduce dangerous air pollution
By Bob Berwyn
Emissions from oil and gas production along the Colorado Front Range are a significant, measurable part of the region’s chronic summer ozone problem, scientists concluded after taking a close look at air pollution during an extensive research project in the summer of 2014.
Ozone levels in the area often spike above 70 parts per billion, a level deemed by the EPA to be dangerous to human health and to the environment, causing respiratory problems and damage to plants. About 17 ppb of that ozone are produced locally; about 3 ppb come from oil and gas industry emissions, according to a new study, published in the Journal of Geophysical Research.
Conservation advocates question plan for expanded fracking in Alaska’s Cook Inlet
Environmental advocates are warning that a plan to expand offshore fracking in Alaska’s Cook Inlet threatens a local population of beluga whales, considered to be among the most endangered whales in the world.
