NOAA extends CU climate studies partnership for 5-10 years
Aug 30th
continue joint leadership of CIRES
The National Oceanic and Atmospheric Administration has selected the University of Colorado Boulder to continue a federal/academic partnership that extends NOAA’s ability to study climate change, improve weather models and better predict how solar storms can disrupt communication and navigation technologies.
The selection means that NOAA will continue funding the Cooperative Institute for Research in Environmental Sciences, or CIRES, for at least five years and up to 10 more years. CIRES was established at CU-Boulder in 1967.
The amount of the award is contingent on the availability of funding in the federal budget, but NOAA anticipates that up to $32 million may be available annually. Total NOAA funding is variable from year to year and is based on the number of projects the university proposes and NOAA approves.
Following a competitive process, NOAA selected CU-Boulder to administer the CIRES partnership which leverages university resources to expand understanding of the “Earth system” — the interrelationships among the atmosphere, oceans, land, living things and the sun’s energy.
“Improving our understanding of the Earth system is critically important as the build-up of greenhouse gases in the atmosphere is forcing changes in all of its processes,” said Robert Detrick, assistant administrator of the NOAA Office of Oceanic and Atmospheric Research and chairman of the NOAA Research Council. “The University of Colorado has been an excellent partner to NOAA in pursuing this mission.”
NOAA’s first cooperative institute, CIRES is marking its 45th anniversary this year and is now one of 18 NOAA cooperative institutes nationwide. NOAA competitively funds cooperative institutes at universities with strong research programs relevant to NOAA’s mission. These institutes provide resources and opportunities that extend beyond the agency’s own research capacity.
“Partnership in environmental research with the NOAA Boulder laboratories is the keystone of CIRES research,” said CIRES Interim Director William Lewis Jr. “We have great ambitions in joint research with NOAA over the next five years.”
The partnership allows researchers at CU-Boulder to receive support for research projects that may involve NOAA scientists, primarily at the Earth System Research Laboratory in Boulder as well as other NOAA cooperative institutes.
The CIRES partnership will focus on nine research themes:
- Air quality in a changing environment
- Climate forcing feedbacks and analysis
- Earth systems dynamics, variability and change
- Management and exploitation of geophysical data
- Regional science and applications
- Scientific outreach and education
- Space weather understanding and predictability
- Stratospheric processes and trends
- Systems and prediction models development
“With pressing issues like air quality, climate change and space weather now at the forefront globally, the University of Colorado Boulder is eager to continue this crucial partnership with NOAA,” said CU-Boulder Vice Chancellor for Research Stein Sture. “CIRES is known around the world for advancing our understanding of the complex Earth system and as a premier institution in educating the next generation of environmental scientists.”
NOAA supports cooperative institutes to conduct research, education, training and outreach aligned with its mission. Cooperative institutes also promote the involvement of students and postdoctoral scientists in NOAA-funded research. This unique setting provides NOAA the benefit of working with the complementary capabilities of a research institution that contribute to NOAA-related sciences ranging from satellite climatology and fisheries biology to atmospheric chemistry and coastal ecology.

Arctic sea ice reaches lowest extent ever recorded, says CU-Boulder research team
Aug 27th
On Aug. 26, the Arctic sea ice extent fell to 1.58 million square miles, or 4.10 million square kilometers. The number is 27,000 square miles, or 70,000 square kilometers below the record low daily sea ice extent set Sept. 18, 2007. Since the summer Arctic sea ice minimum normally does not occur until the melt season ends in mid- to late September, the CU-Boulder research team expects the sea ice extent to continue to dwindle for the next two or three weeks, said Walt Meier, an NSID scientist.
“It’s a little surprising to see the 2012 Arctic sea ice extent in August dip below the record low 2007 sea ice extent in September,” he said. “It’s likely we are going to surpass the record decline by a fair amount this year by the time all is said and done.”
On Sept. 18, 2007, the September minimum extent of Arctic sea ice shattered all satellite records, reaching a five-day running average of 1.61 million square miles, or 4.17 million square kilometers. Compared to the long-term minimum average from 1979 to 2000, the 2007 minimum extent was lower by about a million square miles — an area about the same as Alaska and Texas combined, or 10 United Kingdoms.
While a large Arctic storm in early August appears to have helped to break up some of the 2012 sea ice and helped it to melt more quickly, the decline seen in in recent years is well outside the range of natural climate variability, said Meier. 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.
CU-Boulder researchers say the old, thick multi-year ice that used to dominate the Arctic region has been replaced by young, thin ice that has survived only one or two melt seasons — ice which now makes up about 80 percent of the ice cover. Since 1979, the September Arctic sea ice extent has declined by 12 percent per decade.
The record-breaking Arctic sea ice extent in 2012 moves the 2011 sea ice extent minimum from the second to the third lowest spot on record, behind 2007. Meier and his CU-Boulder colleagues say they believe the Arctic may be ice-free in the summers within the next several decades.
“The years from 2007 to 2012 are the six lowest years in terms of Arctic sea ice extent in the satellite record,” said Meier. “In the big picture, 2012 is just another year in the sequence of declining sea ice. We have been seeing a trend toward decreasing minimum Arctic sea ice extents for the past 34 years, and there’s no reason to believe this trend will change.”
The Arctic sea ice extent as measured by scientists is the total area of all Arctic regions where ice covers at least 15 percent of the ocean surface, said Meier.
Scientists say Arctic sea ice is important because it keeps the polar region cold and helps moderate global climate — some have dubbed it “Earth’s air conditioner.” While the bright surface of Arctic sea ice reflects up to 80 percent of the sunlight back to space, the increasing amounts of open ocean there — which absorb about 90 percent of the sunlight striking the Arctic — have created a positive feedback effect, causing the ocean to heat up and contribute to increased sea ice melt.
Earlier this year, a national research team led by CU embarked on a two-year effort to better understand the impacts of environmental factors associated with the continuing decline of sea ice in the Arctic Ocean. The $3 million, NASA-funded project led by Research Professor James Maslanik of aerospace engineering sciences includes tools ranging from unmanned aircraft and satellites to ocean buoys in order to understand the characteristics and changes in Arctic sea ice, including the Beaufort Sea and Canada Basin that are experiencing record warming and decreased sea ice extent.
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.
