CU scientists: CO2 emissions a HUGE problem
Nov 4th
New calculations showing the global output of heat-trapping carbon dioxide gases jumped by the largest amount on record in 2010 is more evidence that society has made a choice to continue to accelerate climate change, say two University of Colorado Boulder experts.
The new figures calculated by the U.S. Department of Energy show the world pumped more than 560 additional tons of carbon into the atmosphere in 2010 than in 2009, an increase of 6 percent. There are currently 392 parts per million of CO2 in Earth’s atmosphere, a rise of more than 100 since the Industrial Revolution, said CU-Boulder Institute of Arctic and Alpine Research Director Jim White.
The CO2 rise is driven primarily by growing industry in China and India — the two highest users of coal — as well as the United States, said White. “While the world population growth has slowed, the use of fossil fuels continues at a record pace,” he said. Studies have shown Earth’s land temperatures have increased by 1.6 degrees Fahrenheit since the 1950s.
“While it is good news that the global economy continues to grow, we clearly have not taken greenhouse gases and climate change seriously,” said White, an expert on ice cores and climate change. Only a substantial and rapid global move toward alternative energies can slow the growth of CO2 emissions, he said.
“We are rolling the dice here, which is not a good way to plan for the future,” said geography Professor Mark Serreze, director of CU-Boulder’s National Snow and Ice Data Center and an expert on declining Arctic sea ice.
“The warning signs of climate change are all around us, and we have decided to ignore them,” said Serreze. “Humankind has made a choice to do nothing, and we can never go back to where we were again. As a consequence, we will have to adapt to change.”

CU-Boulder, USCS to lead E-vehicle studies
Oct 17th
COLORADO SPRINGS, Colo. – University of Colorado Boulder faculty will join with University of Colorado Colorado Springs faculty to teach courses in the design and implementation of electric vehicle drivetrains to new and retraining engineers.
The U.S. Department of Energy recently provided a five-year $954,000 grant to UCCS for the development of courses to prepare engineers for careers in developing new technologies for vehicles having electric drivetrains. The master’s-level courses will be taught by both UCCS and CU Boulder faculty members with expertise in batteries, battery controls, and power electronics.
The courses will be available through distance learning technologies such as online courses and, possibly, CISCO Telepresence, in addition to traditional in-person classrooms, making them available to people nationwide.
“There are thousands of engineers who have either been displaced as the U.S. auto industry shifted or who have an interest in learning about creating vehicles of the future,” Greg Plett, professor, UCCS College of Engineering and Applied Science, said. “This program offers them the opportunity to retrain without relocating.”
Plett, the principal investigator on the project, has spent his career working with battery controls and has close relationships to many Colorado-based companies who manufacture batteries or their controls as well as large corporations such as General Motors. Plett is working with General Motors’ engineers on new methods for battery controls in future extended range electric vehicles, beyond the Chevy Volt.
The GATE Center of Excellence in Innovative Drivetrains in Electric Automotive Technology Education will provide students the opportunity to earn a graduate certificate in electric drivetrain technology by taking four courses in battery dynamics, battery controls, power electronics and detailed courses in adjustable alternating current drives. Plans also call for creating options for students in master’s of science in electrical engineering programs at UCCS and CU-Boulder to pursue specialization in fields such as battery controls, taught by UCCS faculty, and vehicle power electronics taught by CU-Boulder faculty members.
CU-Boulder faculty will build upon strengths of the Colorado Power Electronics Center research and education programs, including a highly successful Professional Certification in Power Electronics already offered online by the College of Engineering and Applied Science’s distance education program (http://cuengineeringonline.colorado.edu/)
“This program combines the strengths of the faculty of two CU campuses for the benefit of students,” Plett said.
Plett also believes the collaboration of faculty will lead to new research in battery technology. Battery life and power outputs have long been considered hindrances to the development of electric vehicles including cars, trucks and mass transit vehicles.
Plett envisions that fellowships to reduce the cost of the graduate coursework will be available with 30 to 40 students enrolled annually beginning with the fall 2012 semester.
Working with Plett will be Scott Trimboli, assistant professor, UCCS College of Engineering, and Regan Zane, associate professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder, and Dragan Maksimovic, professor, Department of Electrical, Computer, and Energy Engineering, CU-Boulder.
