December 5th, 2013INSTAAR faculty and graduate students will share their research at the American Geophysical Union (AGU) Fall Meeting (http://fallmeeting.agu.org/2013/) held in San Francisco, 9 to 13 December. They will present new research on abrupt climate change, atmospheric chemistry, geomorphology, rivers and oceans, forests and snow, plants and soils, past climates, flood monitoring, Antarctic volcanoes, coastal erosion, and emissions from energy production.
December 3rd, 2013Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present potential threats to nature and society. Abrupt change is already underway in some systems, and large scientific uncertainties about the likelihood of other abrupt changes highlight the need for further research. However, with recent advances in understanding of the climate system, some potential abrupt changes once thought to be imminent threats are now considered unlikely to occur this century. This report summarizes the current state of knowledge on potential abrupt changes to the ocean, atmosphere, ecosystems, and high latitude areas, and identifies key research and monitoring needs. The report calls for action to develop an abrupt change early warning system to help anticipate future abrupt changes and reduce their impacts.
November 20th, 2013The National Oceanic and Atmospheric Administration has awarded a team of scientists, including INSTAAR director James White, with the most recent Office of Oceanic and Atmospheric Research Outstanding Scientific Paper Award for their work on atmospheric methane.
October 24th, 2013Average summer temperatures in the Eastern Canadian Arctic during the last 100 years are higher now than during any century in the past 44,000 years and perhaps as long ago as 120,000 years, says a new INSTAAR study. The study is the first direct evidence the present warmth in the Eastern Canadian Arctic exceeds the peak warmth there in the Early Holocene, when the amount of the sun’s energy reaching the Northern Hemisphere in summer was roughly 9 percent greater than today, says study leader Gifford Miller.
September 24th, 2013Climate Technician Jennifer Morse reports from Niwot Ridge and the Mountain Research Station after the recent historic rains and flooding. Everyone is okay, and the research sites are relatively unaffected. The most direct route to the Station remains closed and will be for some time.
August 21st, 2013Meet the people behind the science—and art—resulting from INSTAAR research, featured in two recent EARTH Magazine interviews.
