CU Women Put Away Pioneers, Eye No. 8 Cardinals
Dec 12th
DENVER – The unbeaten University of Colorado women’s basketball team shook off a lethargic start, took control with an 8-0 run and never looked back in dispatching the University of Denver 83-63 here Tuesday night.
Now the Buffaloes (8-0) can look ahead. Finally, they can focus on their biggest non-conference game – a Friday night date with No. 8 Louisville at the Coors Events Center. The Cardinals are 9-1, with their lone loss by one point (48-47) to archrival Kentucky.
In winning for only the second time in Denver against the Pioneers, the Buffs got a season-high 19 points from Brittany Wilson and 14 points and 11 rebounds from Chucky Jeffery. Leading scorer Arielle Roberson, who entered the game with a 17.3-point average, added 11.
DU defeated CU 70-69 in their most recent Magness Arena matchup on Nov. 16, 2010. The Buffs lead the series 6-2 and won for the third time this season against a Front Range opponent. Before making the trip down I-25 South, CU had beaten Wyoming (68-59) and Colorado State (72-46) in Boulder.
Tuesday’s first half produced 11 lead changes, but they all occurred in the first 10 minutes. DU (4-5) took advantage of CU’s sluggish start to go ahead by as many as five points (13-8) before the visitors roused themselves.
Finally focused, the Buffs made an 18-17 deficit their last of the game. They went on an 8-0 run, getting baskets from Jamee Swan, Roberson (her first of the game), Jeffery and Brittany Wilson on a fast-break assist from Jeffery to go up 25-18 with 6:22 before intermission.
From there until the halftime buzzer, CU increased its lead to 10 on two occasions and led 37-27 at the break. The Buffs got 12 first-half points from Brittany Wilson and nine from Jeffery. Morgan Van Riper-Rose kept the Pioneers close with 13, while none of her teammates managed more than four first-half points. She finished with a career-high 28.
CU shot 41.7 percent (15-for-36) from the field in the opening half to DU’s 37.5 percent (9-for-24). The Buffs owned the boards (25-13) and forced 10 Pioneer turnovers that resulted in seven CU points.
CU outscored DU 9-1 to open the second half and surge ahead 46-28. The Buffs didn’t allow the Pioneers their first field goal of the last 20 minutes until the 14:07 mark. A minute later, CU went up by 23 and wouldn’t allow DU within 15 points the rest of the night.
With 7:55 remaining, Roberson was assessed CU’s first technical foul of the season. The reason: Roberson apparently touched the ball before a Pioneer player was about to throw it in bounds after a made Buffs basket. CU was up 67-44 at the time and led by as many as 26 points in the final 4 minutes.

CU-NOAA study shows summer climate change, mostly warming
Nov 15th
“It is the first time that we show on a local scale that there are significant changes in summer temperatures,” said lead author CIRES scientist Irina Mahlstein. “This result shows us that we are experiencing a new summer climate regime in some regions.”
The technique, which reveals location-by-location temperature changes rather than global averages, could yield valuable insights into changes in ecosystems on a regional scale. Because the methodology relies on detecting temperatures outside the expected norm, it is more relevant to understand changes to the animal and plant life of a particular region, which scientists would expect to show sensitivity to changes that lie outside of normal variability.
“If the summers are actually significantly different from the way that they used to be, it could affect ecosystems,” said Mahlstein, who works in the Chemical Sciences Division of the National Oceanic and Atmospheric Administration’s Earth System Research Laboratory.
To identify potential temperature changes, the team used climate observations recorded from 1920 to 2010 from around the globe. The scientists termed the 30-year interval from 1920 to 1949 the “base period,” and then compared the base period to other 30-year test intervals starting every 10 years since 1930.
The comparison used statistics to assess whether the test interval differed from the base period beyond what would be expected due to yearly temperature variability for that geographical area.
Their analysis found that some changes began to appear as early as the 1960s, and the observed changes were more prevalent in tropical areas. In these regions, temperatures varied little throughout the years, so the scientists could more easily detect any changes that did occur, Mahlstein said.
The scientists found significant summer temperature changes in 40 percent of tropical areas and 20 percent of higher-latitude areas. In the majority of cases, the researchers observed warming summer temperatures, but in some cases they observed cooling summer temperatures.
“This study has applied a new approach to the question, ‘Has the temperature changed in local areas?’ ” Mahlstein said. The study is in press in the journal Geophysical Research Letters, a publication of the American Geophysical Union.
The study’s findings are consistent with other approaches used to answer the same question, such as modeling and analysis of trends, Mahlstein said. But this technique uses only observed data to come to the same result. “Looking at the graphs of our results, you can visibly see how things are changing,” she said.
In particular the scientists were able to look at the earlier time periods, note the temperature extremes, and observe that those values became more frequent in the later time periods. “You see how the extreme events of the past have become a normal event,” Mahlstein said.
The scientists used 90 years of data for their study, a little more than the average lifespan of a human being. So if inhabitants of those areas believe that summers have changed since they were younger, they can be confident it is not a figment of their imagination.
“We can actually say that these changes have happened in the lifetime of a person,” Mahlstein said.
Co-authors on the study were Gabriele Hegerl from the University of Edinburgh in Scotland and Susan Solomon from Massachusetts Institute of Technology.
CIRES is a joint institute of CU-Boulder and NOAA.

Leading quantitative conservation biologist named CU’s first Colorado Chair in Environmental Studies
Oct 1st
The endowed chair in environmental studies was made possible by $4 million in gifts made anonymously in 2009 and 2010 toward the chair.
Sharon Collinge, professor and director of the CU-Boulder Environmental Studies Program, called Doak a perfect match. “He epitomizes what we’re looking for,” she said.
Doak is especially skilled in interdisciplinary research, she said. He brings expertise in policy to his analyses of risks of energy development, for example. And he is widely cited for his research in quantitative conservation biology, which combines sophisticated computer modeling with varying policy scenarios to project changes in populations of rare species.
For instance, the Proceedings of the National Academies of Science recently published a study co-authored by Doak concluding that the California condor is chronically endangered by lead exposure from hunters’ spent ammunition.
While the free-flying condor population has risen in the last three decades, that increase has been achieved through captive breeding, monitoring and veterinary care, the study found. Meanwhile, the primary threat to the endangered bird — lead poisoning from bullets and shotgun shells lodged in carrion — has gone largely unmitigated, the study said.
Doak and his fellow researchers found no evidence that California’s 2008 partial ban on lead ammunition yielded any decrease in lead exposure and poisoning in condors.
Since 2007, Doak has served as a professor of zoology and physiology at the University of Wyoming. Previously, he was a faculty member at the University of California, Santa Cruz. His research has been funded by the National Science Foundation, U.S. Fish and Wildlife Service, U.S. Forest Service, California Department of Fish and Game and the U.S. Bureau of Land Management. Scholarly papers have cited his work more than 3,000 times since 1998.
Doak said he was drawn to CU-Boulder’s Environmental Studies Program because of its breadth, spanning disciplines ranging from biogeochemistry to political science to philosophy. This interdisciplinary focus is necessary to confront some of the world’s most intractable problems, Doak and Collinge said.
“That’s the only way we can really address and resolve some of the major environmental challenges that we face,” Collinge said.
Working with experts from a wide range of disciplines, Doak added, provides a motivation and opportunity “not once a year but every day to confront your own ignorance and thus to appreciate and learn new ideas and approaches.”
It is not that interdisciplinary work is always best, he added. “We need to train ourselves and our students to determine when the problem we are confronting requires an interdisciplinary approach. If you want to build a bridge that won’t fall down, you don’t need an interdisciplinary team. You need a good engineer.”
The critical question, he said, is the following: “Is this problem a nail that requires a hammer, or is this a problem that requires a lot of tools? And most environmental problems require an entire chest of tools and the different people who know how to use them.”
Collinge said students sometimes grasp this distinction better than professors do. “Students who are interested in the environment understand very deeply that they have to know something about politics and policies and how we make choices and why we make choices,” she said. “They’ve essentially pushed us, encouraged us to provide that broad and deep training for them.”
Of the donor’s gift, Collinge said, “This was incredibly generous. And we are really grateful.
“For me, it validates or speaks to the importance of what we’re doing,” she said. “With more than 1,000 undergraduate majors in environmental studies and 50 graduate students, enthusiasm was abundant even before the gift that enabled the endowed chair.”
