“Big Dance” jitters end CU women’s tourney bid
Mar 24th
Chucky Jeffery is one of the best players in CU history and a first round loss won’t diminish the fact.
But scoring the fifth fewest points of the season while allowing the second most was not a formula for success for the Colorado women’s basketball team, as five Kansas players scored in double figures to lead the Jayhawks to a 67-52 upset over the host Buffaloes in an NCAA Women’s Tournament first round game here Saturday.
Seniors Carolyn Davis and Angel Goodrich led the scored 14 points apiece for Kansas (19-13, the 12th seed in the Norfolk Region), which basically limped into the tournament after losing six of its last eight games (and 11 of 18). But the Jayhawks, after falling behind by 10 early, played the like the team that opened the year with seven straight wins on their way to an 11-2 start.
Colorado (25-7, seeded No. 5), was playing in the NCAA Tournament for the first time in a decade, but had to make a go of it without starting center Rachel Hargis, who suffered a knee injury in practice a week ago Friday. It’s safe to say CU missed the junior’s 6-foot-4 presence inside, not only her rebounding but her ability to alter shots.
Colorado started out 6-of-7 from the field in building an early 14-4 edge, but then went cold the rest of the way in the first half (5-of-27) and missed its first seven shots of the second half before a Brittany Wilson layup at 14:02 ended the drought. Meanwhile, KU shot 50 percent in the first half (15-of-30), closing with 11 makes in 18 tries; the Jayhawks made 5-of-6 to open the second for a 16-of-24 performance while turning a 15-9 deficit into a 49-29 lead, the first of two 20-point advantages it had in the game (the other coming at 56-36).
It all added up to a whopping 45-15 comeback after Colorado recorded that early lead.
If the Buffaloes were going to get back in it, they needed a quick start in the second half. But the Jayhawks were not to be denied, scoring the first six points to extend their 10-point intermission lead to 43-27. The margin hovered between 14 points, the closest the Buffs would get on three different occasions, and 18 the remainder of the game.
Kansas opened the scoring on a Davis layup but then Colorado went on a 14-2 run in just over a two minute span, fueled by eight points, including a pair of 3-point baskets, by junior Brittany Wilson. The Jayhawks slowly worked their way back into the game, pulling to within 15-13 on consecutive scores by Monica Engelman at the 11:19 mark. A three-pointer by Lexy Kresl and a layup from Chuck Jeffery put the Buffs back up by seven, 20-13 with 9:12 left in the half.
KU then matched and actually exceeded CU’s early run with one of its own, using a 17-3 spree over the next five-plus minutes to take a 30-23 lead, with Davis and Chelsea Gardner each contributing six points. Davis had 10 points in the half, which ended with a Charlicia Harper three-point shot to give the Jayhawks a 37-27 lead.
“We came out and it was rainin’ in here, and then after a while we couldn’t hit anything,” Wilson said. “I mean, we had open shots, I just think … I don’t really know what happened. Then there were open shots, and we kept saying, ‘just step into it and take another shot.’ I don’t know if it was nervousness, I don’t know what it was, but after a while we just couldn’t hit anything.”
Colorado finished just 16-of-63 from the field, the 25.4 shooting percentage easily its worst of the season. The Buffs came into the game hitting at 39.9 percent, while Kansas was allowing its opponents to click at just 41.1 percent. The Jayhawks converted 46 percent of its tries; otherwise, the only other decided statistical advantages belong to Kansas in assists (16-8) and to Colorado in steals (13-5) and free throw attempts (25-6).
It was just the ninth time in 32 games that the Buffaloes trailed at halftime, and only Stanford had a larger lead at intermission over CU than the Jayhawks; the Cardinal, ranked fourth at the time, led 31-14 en route to a 57-40 win in Boulder back on January 4. In addition, Kansas tied CU on the boards with 42, just the seventh time this year the Buffs did not hold the edge in rebounding; Colorado was 0-5 when getting outrebounded and 1-1 when matched.
Arielle Roberson recorded a double-double for Colorado, scoring 11 points and grabbing 12 rebounds; Wilson tied her for the team scoring lead, also netting 11. Jeffery struggled in her final appearance in a CU uniform, scoring just eight points on 2-of-16 field goal shooting, but did have five rebounds, five assists and two steals.
“It’s very disappointing,” Jeffery said of ending the season this way. “We didn’t want it to end this early. It’s kind of sad being my last game, but I wouldn’t have gone through the season with any other team.”
Jeffery finished her career ranked high on several of CU’s all-time charts, including scoring (1,644 points, sixth), rebounds (921, fifth), assists (481, fourth) and steals (283, fourth). She finished with the fifth most double-doubles (30) and had at least one assist in her last 74 games (and in 123 of 125 for her career).
“No one expected us to be here right now,” Wilson added. “But you know I think that’s a great thing. Chucky has her legacy here, and Megan has her legacy here, and I think we sent them out in a great way. I’m disappointed to lose, and of course no one thought we’d end this early. But we had a great year, and no one expected us to do the things that we’ve done. But when we look back, and once the sting of this is over we’ll be ready to come back.”
Kansas will meet South Carolina Monday night for the right to advance to the Norfolk Regional next weekend; tipoff at the Coors Events Center is 7:30 p.m.
South Carolina Advances With 74-52 Win Over South Dakota State
BOULDER — Seniors Ashley Bruner and Ieasia Walker each scored 15 points to pace four Gamecock players in double figures to lead South Carolina over South Dakota State, 74-52, in the first round of the NCAA Women’s Basketball Tournament here Saturday afternoon.
South Carolina, ranked No. 14 in the nation by the coaches and No. 17 by the Associated Press, pulled away from the Jackrabbits midway through the first half. The score was tied six times and there were eight lead changes, with South Dakota State taking its last lead at 14-13 with 12:02 to play; it remained within two, 21-19, at the 9:34 mark but that’s when the Gamecocks found their stride.
Six different South Carolina players contributed in a 21-4 run over the six minutes that broke the game open, with Tiffany Mitchell scoring five and Walker four to give USC a 40-23 lead; the Gamecocks, seeded No. 4 in the Norfolk Regional, led 44-26 at halftime. South Carolina shot 61 percent in the first half, including 7-of-9 shots in the decisive run.
South Dakota State (25-8, the No. 13 seed) made a couple of mini-runs in the second half, but would get no closer than 15. Senior Ashley Eide led the Jackrabbits with 15 points, the only SDSU player in double figures, with sophomore Gabby Boever adding nine.
Bruner had a double-double, as she collected 11 rebounds for the Gamecocks (25-7), who owned a 40-28 advantage on the boards; she also had a game-high four steals. Elem Ibian scored 13 points off the bench and Mitchell had 11, as no South Carolina starter played over 29 minutes.

CU researchers say deep ice cores show past Greenland warm period may be ‘road map’ for continued warming of planet
Jan 23rd
A new study by an international team of scientists analyzing ice cores from the Greenland ice sheet going back in time more than 100,000 years indicates the last interglacial period may be a good analog for where the planet is headed in terms of increasing greenhouse gases and rising temperatures.
The new results from the NEEM deep ice core drilling project led by the University of Copenhagen and involving the University of Colorado Boulder show that between 130,000 and 115,000 years ago during the Eemian interglacial period, the climate in north Greenland rose to about 14 degrees Fahrenheit warmer than today. Despite the strong warming signal during the Eemian — a period when the seas were roughly 15 to 25 feet higher than today — the surface of the north Greenland ice sheet near the NEEM facility was only a few hundred yards lower than it is today, an indication to scientists it contributed less than half of the total sea rise at the time.
The NEEM project involves 300 scientists and students from 14 countries and is led by Professor Dorthe Dahl-Jensen, director of the University of Copenhagen’s Centre of Ice and Climate. CU-Boulder geological sciences professor and ice core expert Jim White is the lead U.S. investigator on the project. The National Science Foundation’s Division of Polar Programs funded the U.S. portion of the effort.
The new Nature findings showed that about 128,000 years ago, the surface elevation of ice near the NEEM site was more than 650 feet higher than present but the ice was starting to thin by about 2 inches per year. Between about 122,000 and 115,000 years ago, Greenland’s surface elevation remained stable at roughly 425 feet below the present level. Calculations indicate Greenland’s ice sheet volume was reduced by no more than 25 percent between 128,000 years ago and 122,000 years ago, said White.
A paper on the subject was published in the Jan. 24 issue of Nature.
“When we calculated how much ice melt from Greenland was contributing to global sea rise in the Eemian, we knew a large part of the sea rise back then must have come from Antarctica,” said White, director of CU-Boulder’s Institute of Arctic and Alpine Research. “A lot of us had been leaning in that direction for some time, but we now have evidence that confirms that the West Antarctic ice sheet was a dynamic and crucial player in global sea rise during the last interglacial period.”
Dahl-Jensen said the loss of ice mass on the Greenland ice sheet in the early part of the Eemian was likely similar to changes seen there by climate scientists in the past 10 years. Other studies have shown the temperatures above Greenland have been rising five times faster than the average global temperatures in recent years, and that Greenland has been losing more than 200 million tons of ice annually since 2003. The Greenland ice loss study was led by former CU-Boulder scientist Isabella Velicogna, who is currently a faculty member at the University of California, Irvine.
The intense melt in the vicinity of NEEM during the warm Eemian period was seen in the ice cores as layers of re-frozen meltwater. Such melt events during the last glacial period were rare by comparison, showing that the surface temperatures at the NEEM site were in a cold, nearly constant state back then. But on July 12, 2012, satellite images from NASA indicated 97 percent of Greenland’s ice sheet surface had thawed as a result of warming temperatures.
“We were quite shocked by the warm surface temperatures observed at the NEEM ice camp in July 2012,” said Dahl-Jensen. “It was raining at the top of the Greenland ice sheet, and just as during the Eemian period, meltwater formed subsurface ice layers. While this was an extreme event, the present warming over Greenland makes surface melt more likely, and the predicted warming over Greenland in the next 50-100 years will very likely be so strong that we will potentially have Eemian-like climate conditions.”
The Greenland ice core layers — formed over millennia by compressed snow — are being studied in detail using a suite of measurements, including stable water isotope analysis that reveals information about temperature and greenhouse gas levels and moisture changes back in time. Lasers are used to measure the water stable isotopes and atmospheric gas bubbles trapped in the ice cores to better understand past variations in climate on an annual basis — similar in some ways to a tree-ring record.
The results from the Nature study provide scientists with a “road map” of sorts to show where a warming Earth is headed in the future, said White. Of the nine hottest years on Earth on record, eight have come since the year 2000. In 2007 the Intergovernmental Panel on Climate Change concluded that temperatures on Earth could climb by as much as 11 degrees F by 2100.
Increasing amounts of carbon dioxide in the atmosphere from sources like vehicle exhaust and industrial pollution — which have risen from about 280 parts per million at the onset of the Industrial Revolution to 391 parts per million today — are helping to raise temperatures on Earth, with no end in sight, said White.
“Unfortunately, we have reached a point where there is so much carbon dioxide in the atmosphere it’s going to be difficult for us to further limit our impact on the planet,” White said. “Our kids and grandkids are definitely going to look back and shake their heads at the inaction of this country’s generation. We are burning the lion’s share of oil and natural gas to benefit our lifestyle, and punting the responsibility for it.”
In the past, Earth’s journey into and out of glacial periods is thought to be due in large part to variations in its orbit, tilt and rotation that change the amount of solar energy delivered to the planet, he said. But the anthropogenic warming on Earth today could override such episodic changes, perhaps even staving off an ice age, White said.
While three previous ice cores drilled in Greenland in the last 20 years recovered ice from the Eemian, the deepest layers were compressed and folded, making the data difficult to interpret. Although there was some folding of the lowest ice layers in the NEEM core, sophisticated ice-penetrating radar helped scientists sort out and interpret the individual layers to paint an accurate picture of the warming of Earth’s Northern Hemisphere as it emerged from the previous ice age, White said.
In addition to White, other CU-Boulder co-authors on the NEEM paper include INSTAAR scientist Bruce Vaughn and graduate student Tyler Jones of INSTAAR and CU-Boulder’s Environmental Studies Program.
“It’s a challenge being on the ice sheet, because we are out of our comfort zones and are working long, physical hours in an environment that is extremely cold and where the sun never sets,” Jones said. “Being a member of the research team allowed me to understand the ice core recovery process and the science behind it in terms of learning more about past climates and the implications for future climate change.”
Other nations involved in NEEM include Belgium, Canada, France, Germany, Iceland, Japan, Korea, the Netherlands, Sweden, Switzerland and the United Kingdom. Other U.S. institutions involved in the effort include Oregon State University, Penn State, the University of California, San Diego and Dartmouth College.

CU Men Grind Out Road Win Against Cougars
Jan 20th
By B.G. Brooks, CUBuffs.com Contributing Editor
PULLMAN, Wash. – On a night when the Colorado Buffaloes’ offense came and went, their constant was defense – and it carried them to their second Pac-12 Conference victory and first of the season on the road.
CU kept grinding and grinding and finally put away Washington State 58-49 Saturday night at Beasley Coliseum. The Buffs went to 12-6 overall and 2-4 in the Pac-12, while the Cougars dropped to 10-8, 1-4.
Buffs coach Tad Boyle told his team that the “hungrier, tougher team” would win Saturday night – and his team proved to be both. CU survived a cold-shooting final 6:15 of the first half and fell behind by four points early in the second half.
But the Buffs rallied behind their defense and late offense provided by Spencer Dinwiddie, whose three-pointer in the game’s last 6 minutes helped keep the Cougars at bay. That shot restored a five-point lead, and he followed with a pair of free throws at the 4:37 mark for another five-point margin.
“That was an ugly win, we have got to get better offensively. We only put up 44 shots to their 58 and we had some silly turnovers, but again, you take a win on the road,” said CU head coach Tad Boyle on 850 KOA. “I thought that there were a couple key performances tonight; number one: Andre [Roberson] was terrific on [Washington State’s Brock] Motum tonight as he made him work for everything. He is the difference in the game defensively, people are going to look at his stat line and maybe say ‘Oh Andre had an off night’ but he didn’t have an off night on defense. They were obviously boxing him out, they were face guarding him and being physical with him, but he was driven.”
“Number two: Xavier Johnson, really gave us great minutes tonight and got inside and he is a beast down there. And then ‘Ski [Booker] made some shots when he had to make shots. He’s 3-for-11 so his efficiency is not very good but two of his three that he made were big shots in the second half and then he had a great assist to Xavier [Johnson] and that is where we kind of blew it open.”
Dinwiddie led CU with 16 points, with Xavier Johnson contributing 14 and Josh Scott 11. WSU got 13 each from Brock Motum and Mike Ladd.
The Buffs held the Cougars to 34.5 percent from the field – their second straight game of keeping an opponent below 40 percent. CU shot 43.2 percent, including 47.8 in the second half. Freshman Xavier Johnson was effective inside
CU comes home next week to play Stanford (Thursday, 8 p.m.) and California (Sunday, 1:30 p.m.) before traveling to Utah the following Saturday to open February.
The Buffs led 23-19 at halftime, but it took a buzzer-beating three-pointer by Will DiOrio to get the Cougars that close. After a 9-9 tie, CU went ahead by as many as seven point on four occasions during the half’s final 6:15.
Among Boyle’s Saturday night goal for the Buffs was to be more selective in their shot selection and move the ball like they’ve shown they’re capable of in practice. CU was hit-and-miss in both areas, with the offense bogging down at times and the Buffs playing their second consecutive game without a three-pointer in the opening 20 minutes.
In fact, CU finished the half’s final 6:15 without a field goal, getting four of four free throws from Scott and one of two from Xavier Johnson to maintain their seven-point lead until DiOrio’s late trey.
But if the Buffs’ offensive struggles continued, they also continued to play the same brand of rugged defense shown three nights early at Washington. WSU’s 29.6 field goal percentage (8-for-27) was the lowest by a CU opponent this season at halftime, as were the Buffs’ and Cougars’ combined 42 first-half points.
CU’s plan was to go inside to the 6-10 Scott, and it worked in the opening half. For the fifth time in his freshman year, he went to the locker room as the Buffs’ scoring leader, getting nine points on two of five field goals and five of six free throws.
The Cougars outscored the Buffs 7-2 in the second half’s first 31/2 minutes and regained the lead (26-25) for the first time since 9-7. CU took it back (27-26) on a pair of Eli Stalzer free throws but WSU five consecutive points from Royce Woolridge to take its largest advantage (31-27) to that point.
The Buffs desperately needed a field goal – and Johnson provided a pair to pull them within one point (32-31). A fast-break layup by Spencer Dinwiddie pushed CU back ahead by one, setting up what appeared would be a back-and-forth final 10 minutes.
It was – for maybe a minute and a half.
Askia Booker, who had two first-half points on one-for-five shooting, hit a jumper to pull the Buffs into a 37-37 tie, Dinwiddie followed with a traditional three-point play, then Booker buried another jumper for a 42-37 CU advantage.
WSU had 7:21 to make up the five-point deficit, but could get no closer than three in the final 5 minutes. CU increased its lead to 11 (58-47) on two free throws by Roberson Booker with 28.3 seconds to play – and the Buffs finally could feel safe about a rare road win.
