Assault suspect from 2012 bar fight still wanted by police
Mar 1st
Boulder police are still investigating an assault case from March 2, 2012, which took place at Conor O’Neill’s Pub, located at 1922 13th St. around 12:37 a.m. The suspect remains unidentified and police are asking the public for assistance.
The male victim was in the restroom when the male suspect tried to enter the stall. The two men pushed each other and at one point, the suspect attacked the victim with a beer bottle. The victim was taken to the hospital to be treated for his injuries which included a concussion, cuts to his head and face and wounds on his chest and arms from the beer bottle.
The suspect fled the bar, and the victim believes a friend of the suspect tried to detain the victim as the suspect got away. The suspect was seen running westbound across 13th St. and through a parking lot. Police were unable to locate him.
At the time of the assault, the Boulder Police Department released a composite sketch and a description of the suspect. The suspect has not yet been identified and police are publicizing the information again, hoping that a member of the public may recognize the suspect and contact police.
The sketch is attached. The suspect is described as:
· White male
· 21 – 29 years old
· 6’0 – 6’3” tall, weighing 180 – 200 pounds
· Build was described as “not toned”
· Short blonde hair which may have been bleached or highlighted
· Witnesses described him as a “surfer type”
· At the time of the assault, was wearing a light-colored shirt or white shirt with blue pinstripes

Volcanic aerosols, not pollutants, tamped down recent Earth warming, says CU study
Mar 1st
A team led by the University of Colorado Boulder looking for clues about why Earth did not warm as much as scientists expected between 2000 and 2010 now thinks the culprits are hiding in plain sight — dozens of volcanoes spewing sulfur dioxide.
The study results essentially exonerate Asia, including India and China, two countries that are estimated to have increased their industrial sulfur dioxide emissions by about 60 percent from 2000 to 2010 through coal burning, said lead study author Ryan Neely, who led the research as part of his CU-Boulder doctoral thesis. Small amounts of sulfur dioxide emissions from Earth’s surface eventually rise 12 to 20 miles into the stratospheric aerosol layer of the atmosphere, where chemical reactions create sulfuric acid and water particles that reflect sunlight back to space, cooling the planet.
Neely said previous observations suggest that increases in stratospheric aerosols since 2000 have counterbalanced as much as 25 percent of the warming scientists blame on human greenhouse gas emissions. “This new study indicates it is emissions from small to moderate volcanoes that have been slowing the warming of the planet,” said Neely, a researcher at the Cooperative Institute for Research in Environmental Sciences, a joint venture of CU-Boulder and the National Oceanic and Atmospheric Administration.
A paper on the subject was published online in Geophysical Research Letters, a publication of the American Geophysical Union. Co-authors include Professors Brian Toon and Jeffrey Thayer from CU-Boulder; Susan Solomon, a former NOAA scientist now at the Massachusetts Institute of Technology; Jean Paul Vernier from NASA’s Langley Research Center in Hampton, Va.; Catherine Alvarez, Karen Rosenlof and John Daniel from NOAA; and Jason English, Michael Mills and Charles Bardeen from the National Center for Atmospheric Research in Boulder.
The new project was undertaken in part to resolve conflicting results of two recent studies on the origins of the sulfur dioxide in the stratosphere, including a 2009 study led by the late David Hoffman of NOAA indicating aerosol increases in the stratosphere may have come from rising emissions of sulfur dioxide from India and China. In contrast, a 2011 study led by Vernier — who also provided essential observation data for the new GRL study — showed moderate volcanic eruptions play a role in increasing particulates in the stratosphere, Neely said.
The new GRL study also builds on a 2011 study led by Solomon showing stratospheric aerosols offset about a quarter of the greenhouse effect warming on Earth during the past decade, said Neely, also a postdoctoral fellow in NCAR’s Advanced Study Program.
The new study relies on long-term measurements of changes in the stratospheric aerosol layer’s “optical depth,” which is a measure of transparency, said Neely. Since 2000, the optical depth in the stratospheric aerosol layer has increased by about 4 to 7 percent, meaning it is slightly more opaque now than in previous years.
“The biggest implication here is that scientists need to pay more attention to small and moderate volcanic eruptions when trying to understand changes in Earth’s climate,” said Toon of CU-Boulder’s Department of Atmospheric and Oceanic Sciences. “But overall these eruptions are not going to counter the greenhouse effect. Emissions of volcanic gases go up and down, helping to cool or heat the planet, while greenhouse gas emissions from human activity just continue to go up.”
The key to the new results was the combined use of two sophisticated computer models, including the Whole Atmosphere Community Climate Model, or WACCM, Version 3, developed by NCAR and which is widely used around the world by scientists to study the atmosphere. The team coupled WACCM with a second model, the Community Aerosol and Radiation Model for Atmosphere, or CARMA, which allows researchers to calculate properties of specific aerosols and which has been under development by a team led by Toon for the past several decades.
Neely said the team used the Janus supercomputer on campus to conduct seven computer “runs,” each simulating 10 years of atmospheric activity tied to both coal-burning activities in Asia and to emissions by volcanoes around the world. Each run took about a week of computer time using 192 processors, allowing the team to separate coal-burning pollution in Asia from aerosol contributions from moderate, global volcanic eruptions. The project would have taken a single computer processor roughly 25 years to complete, said Neely.
The scientists said 10-year climate data sets like the one gathered for the new study are not long enough to determine climate change trends. “This paper addresses a question of immediate relevance to our understanding of the human impact on climate,” said Neely. “It should interest those examining the sources of decadal climate variability, the global impact of local pollution and the role of volcanoes.”
While small and moderate volcanoes mask some of the human-caused warming of the planet, larger volcanoes can have a much bigger effect, said Toon. When Mount Pinatubo in the Philippines erupted in 1991, it emitted millions of tons of sulfur dioxide into the atmosphere that cooled the Earth slightly for the next several years.
The research for the new study was funded in part through a NOAA/ ESRL-CIRES Graduate Fellowship to Neely. The National Science Foundation and NASA also provided funding for the research project. The Janus supercomputer is supported by NSF and CU-Boulder and is a joint effort of CU-Boulder, CU Denver and NCAR.

Boulder releases findings related to possible creation of a municipal electric utility
Feb 21st
The City of Boulder today released a 38-page report detailing the results of extensive research into the possibility of creating a city-owned and operated electric utility. The evaluation looked at a total of six options for meeting the community’s Energy Future goals. One is a baseline evaluation of staying with Xcel Energy with no change to the way it operates. The other five are options predicated on the city creating its own utility, which would be free from regulations that can limit innovation and customization.
The results show that there are several forms a new utility could take that don’t require trade-offs among the community’s core values. The Boulder community has said it wants cleaner and greener energy with rates and reliability comparable to or better than those provided by Xcel Energy. The community is also seeking more local control and a voice in decision-making, as well as an opportunity to enhance economic vitality by providing a test bed for emerging technology and a low-cost, high-reliability environment in which businesses can thrive.
When Boulder voters approved the continued exploration of a municipal utility in November 2011, they set limiting requirements in the Charter that must be met before City Council could proceed. These included provisions related to rates, revenue sufficiency and reliability, as well as plans to reduce greenhouse gas (GHG) emissions and increase renewable sources of energy.
Specific Findings
Under some of the options analyzed, a municipal electric utility would meet the Charter metrics and have a high likelihood of being able to:
· Offer all three major customer classes (residential, commercial and industrial) lower rates than what they would pay Xcel, not just on day one, as required by the Charter, but on average over 20 years;
· Maintain or exceed current levels of system reliability and emergency response, and, if the community chose to, use future investments to enhance dependability;
· Reduce harmful greenhouse gas emissions by more than 50 percent from current levels and exceed the Kyoto Protocol target in year one;
· Obtain 54 percent or more of its electricity from renewable resources; and
· Create a model public electric utility with leading-edge innovations in reliability, energy efficiency, renewable energy, related economic development and customer service.
The report also examines the impact that a variety of stranded cost and acquisition cost rulings could have on rates and revenue requirements over 20 years.
The full memo, with all attachments, is available at www.boulderenergyfuture.com.
Process and Participation
“We are excited to share the results of this detailed analysis with City Council and our community. We believe the findings demonstrate that a municipal utility could be good for consumers, good for Boulder businesses and good for our planet,” said Heather Bailey, executive director of Energy Strategy and Electric Utility Development. “We look forward to an informed conversation over the next couple of month about how best to proceed.”
Bailey said she is especially grateful for the participation of more than 50 community members, many of whom have industry expertise, who donated their time to serve on working groups. These groups helped to ensure that a variety of perspectives was included and that all modeling was based on reasonable assumptions and data.
“This has been a community-wide review process, and this has greatly enhanced the quality and integrity of our report,” Bailey said. “I wish to thank everyone who has played a role in this direct way, as well as the countless members of the public who have shared their thoughts and concerns with me over the past year.”
An Xcel Energy Partnership Alternative?
While the city is committed to exploring ways to achieve “the electric utility of the future,” it has acknowledged that there might be ways to do so short of creating its own utility – in the form of a new partnership with the existing electric provider, Xcel Energy.
In December, the city released a paper that outlined a variety of ideas that could achieve the community’s goals if Xcel Energy is interested. The city has since spoken with officials from the current utility several times, asking them to identify which of the suggestions they would be willing to consider, as well as any innovative approaches the company might like to propose. Xcel officials have said they are open to a dialogue but have not yet come forward with specifics about what ideas they would like to discuss.
The framework for considering how the city should proceed includes the possibility of modeling an Xcel partnership option, when and if additional details become available. There are, in the analysis released today, also at least two options that might be achievable with the participation of a collaborative and willing energy partner.
“What we are looking to do is move beyond a 19th century approach to providing energy and create a forward-looking, innovative and consumer-friendly utility model that reduces our reliance on fossil fuels,” Bailey said. “Xcel Energy has served us for decades, and in many ways, done an admirable job. It is possible they could help us meet our objectives. We would welcome their involvement in a meaningful, timely and transparent discussion.”
What’s Next
Boulder City Council is scheduled to hear a presentation based on this memo and ask questions at a Study Session on Tuesday, Feb. 26. The session will be broadcast live on Comcast Channel 8 for Boulder viewers and online at www.boulderchannel8.com. A recording will also be available at the above website for later viewing. There is no opportunity for public comment at study sessions, but they are an excellent way to learn more about a topic and the staff’s work.
City Council will discuss this issue again – and decide whether to move forward with the next steps related to the potential creation of a city electric utility – on April 16. This meeting will begin at 6 p.m. in Council Chambers at 1777 Broadway and will include a public hearing.
Opportunities for Public Feedback
Between now and council’s April 16 decision, the city is providing multiple ways for the community to provide input about the analysis and how council might move forward.
As always, council accepts correspondence on any issue of community interest. In addition, there is a comment form available for this specific initiative on the project website.
In addition, the city is offering the following unique opportunities:
· An online questionnaire that will be available at www.bouldercolorado.gov between Feb. 27 and March 27;
· A conference telephone call designed to focus on rates and reliability, two key concerns for the business community, from noon to 1 p.m. on Tuesday, March 12 (please register in advance at www.bouldercolorado.gov/energyfuture/businesscall);
· A community open house exploring the pros and cons of each of the modeled options from 6:30 to 8:30 p.m. on Wednesday, March 13, at the West Senior Center, 909 W. Arapahoe Ave.;
· Focused questions and examination of the options on the city’s new digital town hall platform, Inspire Boulder; and
· Presentations, by invitation, from Bailey or other members of the staff team to interested organizations and associations.
All input collected during the next couple of months will be shared with council in advance of the April 16 meeting.
