CU Boulder Jobs up 23% for grads
Sep 27th
FULL-TIME JOB POSTING GRADS JUMPED 23 PERCENT IN 2010-11
For the second year in a row, the University of Colorado Boulder saw an increase in companies seeking to hire CU-Boulder graduates with full-time job postings on campus jumping 23 percent for the 2010-11 school year, compared with 2009-10.
The number of interviews companies conducted on campus also saw an uptick, increasing 9.6 percent during the same period, a testament to the quality of a CU degree even in a weak job market, according to Lisa Severy, director of CU-Boulder’s Career Services office.
“Our recent graduates are having a lot of success in the job search, especially people who are prepared and engaged in their job search,” Severy said. “The best ways to be engaged while you are a student is to take advantage of campus career fairs and information sessions, use the campus job posting tools and network outside of school.”
In terms of sheer volume of job listings, technical skills are in high demand, Severy said. For example, graduates with degrees in computer science and electrical engineering are always in high demand. A relatively new trend in the job market is companies seeking social media specialists, she said.
“This is a niche many graduates can fill, because companies don’t have this expertise yet,” Severy said. “Graduates of any major who are knowledgeable about social media and enjoy working with it should have a lot of opportunities right now.”With so many applicants for every job, one would think it would make recruiters’ jobs easier, but that is not necessarily the case, according to Severy.
“We hear from recruiters that they are avoiding the mass marketing of jobs because they get way too many applicants,” Severy said. “Instead, they target small, quality pools of candidates that they can trust, which includes our system that is open only to CU-Boulder students and graduates.”
Since 2009, CU-Boulder has offered job search assistance to alumni, free of charge. Services such as the university’s online job-posting tool can be a real benefit because only alumni can access the system, she said.
The increase in recruiting activities also is impacting the upcoming fall career and internship fair on campus. While the event usually is held in the University Memorial Center’s Glenn Miller Ballroom, this year more space was required, Severy said.
“We’re sticking employers everywhere we can find space to provide as many opportunities to our students and graduates as possible,” she said.
The fall career and internship fair for CU-Boulder students and alumni will be held Oct. 5 from 9 a.m. to 3 p.m. in the UMC. The fair is open only to CU-Boulder students and alumni.

Boulder CU: Arctic sea ice all-time low
Sep 15th
ARCTIC SEA ICE REACHES MINIMUM 2011 EXTENT,
THE SECOND LOWEST IN THE SATELLITE RECORD
THE SECOND LOWEST IN THE SATELLITE RECORD
The blanket of sea ice that floats on the Arctic Ocean appears to have reached its lowest extent for 2011, the second lowest recorded since satellites began measuring it in 1979,
The Arctic sea ice extent fell to 1.67 million square miles, or 4.33 million square kilometers on Sept. 9, 2011.
While this year’s September minimum extent was greater than the all-time low in 2007, it remains significantly below the long-term average and well outside the range of natural climate variability, according to scientists involved in the analysis. Most scientists believe the shrinking Arctic sea ice is tied to warming temperatures caused by an increase in human-produced greenhouse gases pumped into Earth’s atmosphere.
“Every summer that we see a very low ice extent in September sets us up for a similar situation the following year,” said NSIDC Director Mark Serreze, also a professor in CU-Boulder’s geography department. “The Arctic sea ice cover is so thin now compared to 30 years ago that it just can’t take a hit anymore. This overall pattern of thinning ice in the Arctic in recent decades is really starting to catch up with us.”
Serreze said that in 2007, the year of record low Arctic sea ice, there was a “nearly perfect” set-up of specific weather conditions. Winds pushed in more warm air over the Arctic than usual, helping to melt sea ice, and winds also pushed the floating ice chunks together into a smaller area. “It is interesting that this year, the second lowest sea ice extent ever recorded, that we didn’t see that kind of weather pattern at all,” he said.
The last five years have been the five lowest Arctic sea ice extents recorded since satellite measurements began in 1979, said CU-Boulder’s Walt Meier, an NSIDC scientist. “The primary driver of these low sea ice conditions is rising temperatures in the Arctic, and we definitely are heading in the direction of ice-free summers,” he said. “Our best estimates now indicate that may occur by about 2030 or 2040.”
There still is a chance the sea ice extent could fall slightly due to changing winds or late season melt, said Meier. During the first week of October, CU-Boulder’s NSIDC will issue a full analysis of the 2011 results and a comparison to previous years.
NSIDC is part of CU-Boulder’s Cooperative Institute for Research in Environmental Sciences — a joint institute of CU-Boulder and the National Oceanic and Atmospheric Administration headquartered on the CU campus — and is funded primarily by NASA.
NSIDC’s sea ice data come from the Special Sensor Microwave Imager/Sounder sensor on the Defense Meteorological Satellite Program F17 satellite using methods developed at NASA’s Goddard Space Flight Center in Greenbelt, Md.
Evidence of global climate in Southern Hemisphere

SOUTHERN SOUTH AMERICAN WILDFIRES
EXPECTED TO INCREASE, SAYS CU STUDY
A new University of Colorado Boulder study indicates a major climate oscillation in the Southern Hemisphere that is expected to intensify in the coming decades will likely cause increased wildfire activity in the southern half of South America.
The research team used tree rings dating to 1506 to track past wildfire activity in the forests of Patagonia tied to the Southern Annular Mode, or SAM, a climate oscillation that creates low atmospheric pressure in the Antarctic that is tied to warmer and drier conditions in southern South America. The tree rings showed that when SAM was in its positive phase, there were widespread fires in both dry woodlands and rainforests in Patagonia, a region that straddles Argentina and Chile, said CU-Boulder Research Associate Andres Holz, lead study author.
“Our study shows for about the past 250 years, the Southern Annular Mode has been the main driver in creating droughts and fires in two very different ecosystems in southern South America,” said Holz. “Climate models suggest an increase in SAM beginning in the 1960s due to greenhouse gas increases and Antarctic ozone depletion probably will cause this region to be drought-prone and fire-prone for at least the next 100 years.”
A paper on the subject by Holz and CU-Boulder geography Professor Thomas Veblen was published in Geophysical Research Letters.
Holz and Veblen compared past wildfire records for two ecologically distinct regions in Patagonia — the relatively dry region of southern Patagonia in Argentina and the temperate rainforest of Patagonia in northern Chile. While the tree ring historical record showed increased fires in both regions correlated with a positive SAM, the trend has been less pronounced in northern Patagonia in the past 50 years, likely because of fire-suppression efforts there, Holz said.
But the decades of fire suppression have caused the northern Patagonian woodlands to become denser and more prone towildfire during hot and dry years, Holz said.
“Even in areas of northern Patagonia where fire suppression previously had been effective, record surface areas of woodlands and forests have burned in recent years of extreme drought,” said Veblen. “And since this is in an area of rapid residential growth into wildland-urban interface areas, this climate-driven trend towards increasing fire risk is becoming a major problem for land managers and homeowners.”
The two CU-Boulder researchers studied reconstructions of tree rings going back more than 500 years from 432 trees at 42 sample sites in northern Argentina and southern Chile — the largest available data set of annual, readable tree ring records in the Southern Hemisphere. The tree rings, which indicate climate cycles and reveal the scars of old fires, showed that wildfires generally increased in both regions when SAM was in its strong, positive phase.
Although the Antarctic ozone hole stopped growing in about 2000 as a result of a ban on ozone-depleting gases and now appears to be slowly repairing itself, a 2011 paper by researchers at the National Center for Atmospheric Research in Boulder indicates ozone recovery and greenhouse gas influences essentially will cancel each other out, preventing SAM from returning to its pre-1960s levels.
“Before the Industrial Revolution, SAM intensified naturally at times to create drought situations in Patagonia,” Holz said. “But in the last 80 years or so, the natural variation has been overwhelmed by a bias toward a positive SAM phase because of ozone-depleting chemicals and greenhouse gases we have put in the atmosphere.”
The research effort was supported by the National Geographic Society, the National Science Foundation, the CU Beverly Sears Small Grants Program and the Council on Research and CreativeResearch of the CU Graduate School.
“As warming and drying trends continue, it is likely that wildfire activity will increase even in woodland areas where fire suppression has previously been effective,” Holz and Veblen wrote in Geophysical Research Letters.
