Study shows how changing ocean chemistry slows life cycle
Ocean acidification could take a bite out of the economically important Dungeness crab fishery along the Pacific Northwest coast. As the oceans absorb more CO2 from the atmosphere, the increasingly corrosive water is likely slow development and reduce survival of the crab’s larval stages, according to new research by the NOAA Fisheries Northwest Fisheries Science Center in Seattle.
Ocean acidification is one of the most serious effects of increasing CO2 emissions from fossil fuel combustion. Based on what we know about emissions trends, the average pH of surface waters off the Pacific Northwest Coast is expected to drop to about 7.8, and even more when periodic upwelling carries deep water to the surface. Acidification has already been found to slow coral growth, impair shark feeding, and speed the spread of invasive species, among other impacts.
The study, recently published in the journal Marine Biology, shows that the crab larvae hatched at the same rate regardless of pH, but those that hatched at lower levels showed signs of slowed development. The researchers suggested that the lower pH may reduce the metabolic rate of embryos. That could extend their vulnerable larval period, or could jeopardize the timing of their development in relation to key food sources, the scientists said.

Study suggests good labeling could help shape consumer decisions
The grand international climate deal reached in Paris late last year was an encouraging step toward curbing global greenhouse gas emissions, but the agreement will ultimately work only if individuals are prepared to do their part. And according to a new set of studies by a trio of university researchers, consumers may be ready to step up.
Will marijuana sales undermine the family vibe at a ski area where pot has been openly consumed since the 1970s?
Keystone-area old-timers who are totally OK with the purchase and consumption of alcohol are trying to rally their neighbors to oppose a proposed retail marijuana store near the resort, claiming it would undermine Keystone’s family atmosphere.
Arapahoe Basin Ski Area is one step closer to gaining final approval for a 492-acre expansion that would include a new lift in the Beavers area. The ski area plan also calls for replacing Pallavicini chairlift, removing the Norway chairlift and adding a surface lift to ferry skiers and snowboarders to the popular backside Montezuma Bowl terrain.
Last week, the U.S. Forest Service released a draft environmental study for the planned projects. The agency will take public comments on the draft EIS through March 21. More information is online at: http://www.fs.usda.gov/project/?project=41664. A public meeting on the draft Eis will be held at The Keystone Center (1628 St John Rd., Dillon, CO 80435) on March 2, 2016 from 5:00 to 7:00 p.m.
State commission will meet Jan. 25 to take action on proposed regulations
The Colorado Oil and Gas Conservation Commission is set to take some modest steps to strengthen its oversight of oil and gas development in Colorado by considering new rules that would require more cooperation between fracking operators and local communities.
The commission will meet Jan. 25 to consider rules that would ensure that fossil fuel companies provide earlier notice to local governments, as well as an opportunity for local officials to work with operators on the location of large oil and gas facilities adjacent to communities.

States free to move ahead with energy transition plans
A federal appeals court this week rejected a last-ditch effort by fossil fuel companies to block implementation of the EPA’s Clean Power Plan, which is aimed at curbing heat-trapping pollution from power plants.
