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.

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.
The turnout wasn’t exactly overwhelming, but those Breckenridge voters who did bother to cast a ballot Tuesday overwhelmingly voted in favor of a ballot measure authorizing a 4.5 percent lift ticket tax.
Voters support new tax to address parking and congestion
FRISCO — Polling early this summer in Breckenridge appears to confirm what many residents and visitors already know — parking and congestion are serious issues for the Colorado resort town, which in some ways is choking on its own success.
‘I want to hear what people in small communities are doing and carry those stories to the highest level …’
FRISCO — Colorado’s outdoor recreation industry — from skiing and snowmobiling, to birdwatching and hunting — has become a powerful economic force in the last few decades.
By some accounts, the industry generates as much as $13 billion per year in consumer spending and drives the economy of many communities outside the urban Front Range corridor. According to the Outdoor Industry Association, the industry contributes $4.2 billion in wages and salaries in Colorado.
Now, Gov. John Hickenlooper says he wants to boost the industry’s role to an even higher profile by establishing a new Colorado Outdoor Recreation Industry Office, housed in the Colorado Office of Economic Development and International Trade. Last week, Hickenlooper announced that Eagle County resident Luis Guillermo Benitez will head the new office’s efforts build the state’s outdoor recreation brand.
