October 13th, 2016A single season of intense melting that affected Antarctica between 2001 and 2002 offers new insights into the southernmost continent's ecological future and the potential impact of climate change worldwide, according to observations collected in a series of papers and published in the journal BioScience.
August 13th, 2016Thunderstorms are powerful things: their churning circulation can stir gases from the lower atmosphere into the upper atmosphere and even the lower stratosphere. They can also scrub gases out of the air by dissolving them in raindrops, a process known as scavenging. In a new study, INSTAAR scientists in collaboration with other scientists at CU and NCAR found that scavenging is not nearly as effective as previously believed for some soluble and highly reactive trace gases, a result that may change our views of atmospheric chemistry in a warming climate.

April 4th, 2014Tsegay Wolde-Georgis, of the INSTAAR program Consortium for Capacity Building (CCB), is leading a project to introduce the cultivation of apple trees irrigated by water-filled, buried clay pots to the mountainous, dry region of Atebes, a village of 4000 people in northern Ethiopia. Over the last 30 years, land degradation and climate change have exacerbated existing constraints of drought, soil erosion, deforestation, poor food supply consisting entirely of cereal grains, and lack of access to water. The goal of the clay pot project is to improve the resiliency of the community to climate-related hazards through demonstration and capacity building. So far, the project has led not only to the cultivation of high-value fruits and vegetables, but to erosion control and improved water supplies.
March 3rd, 2014An analysis published Feb. 26 in the journal Nature Climate Change shows that the wastewater produced during the processing of palm oil is a significant source of heat-trapping methane in the atmosphere.

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.

July 31st, 2013A new study involving Giff Miller, Jim White, and former students and postdocs suggests that an ice-free Arctic Ocean may have amped up temperatures during the Pliocene Epoch. Year-round ice-free conditions across the Arctic Ocean could explain why the Earth was substantially warmer during the Pliocene Epoch than it is today, despite similar concentrations of carbon dioxide in the atmosphere, according to the research published online in Palaeogeography, Palaeoclimatology, Palaeoecology.
May 16th, 2013While 99 percent of Earth’s land ice is locked up in the Greenland and Antarctic ice sheets, the remaining ice in the world’s glaciers contributed just as much to sea rise as the two ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving INSTAAR Fellow Tad Pfeffer.
January 24th, 2013New results from the international NEEM deep ice core drilling project on Greenland, analyzing cores 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.
October 26th, 2012Chasing Ice, a documentary by director Jeff Orlowski that has won awards at film festivals around the world, is being released nationally in U.S. theaters starting in mid-November. The film follows photographer and INSTAAR affiliate James Balog as he and his team in the Extreme Ice Survey capture stunning time-lapse footage of melting glaciers, despite balky equipment, sideways terrain, terrible weather, and personal injury.
September 10th, 2012A new University of Colorado Boulder-led study that ties forest “greenness” in the western United States to fluctuating year-to-year snowpack indicates mid-elevation mountain ecosystems are most sensitive to rising temperatures and changes in precipitation and snowmelt. Led by CU-Boulder researcher Ernesto Trujillo and Assistant Professor Noah Molotch, the study team identified the threshold where mid-level forests sustained primarily by moisture change to higher-elevation forests sustained primarily by sunlight and temperature. Being able to identify this “tipping point” is important because it is in the mid-level forests--at altitudes from roughly 6,500 to 8,000 feet--where many people live and play in the West and which are associated with increasing wildfires, beetle outbreaks and increased tree mortality.
September 7th, 2012Warmer air temperatures since the 1980s may explain significant increases in zinc and other metal concentrations of ecological concern in a Rocky Mountain watershed, reports a new study led by CU-Boulder and the USGS. Rising concentrations of zinc and other metals in the upper Snake River just west of the Continental Divide near Keystone, Colo., may be the result of falling water tables, melting permafrost and accelerating mineral weathering rates, all driven by warmer air temperatures in the watershed. Researchers observed a fourfold increase in dissolved zinc over the last 30 years during the month of September.
August 29th, 2012Global experts in climate change politics and policy will be in Boulder September 13-15 for the International Conference on Culture, Politics & Climate Change.

January 7th, 2011North Atlantic water flowing into the Arctic Ocean is warmer than it has been in at least 2,000 years, which is likely amplifying global warming in the Arctic, says a new international study involving INSTAAR fellow Tom Marchitto. The team believes that the rapid warming of the Arctic and recent decrease in sea ice extent are tied to the enhanced heat transfer from the North Atlantic Ocean.
December 10th, 2010Caitlin Crouch and Diane McKnight found that rising concentrations of zinc in the Snake River watershed on Colorado's Western Slope may be the result of earlier spring snowmelt. They observed a four-fold increase in dissolved zinc over the last 30 years during September and October, the lowest water flow months. They also noticed that the low flows have become lower - and probably the soil along the stream drier - as air temperatures have risen and snowmelt has begun two to three weeks earlier.
November 10th, 2010A research team led by Tom Marchitto has found evidence supporting an important role for the Sun in regional-scale climate variability. They found that slow variations in solar output have nudged the circulation of the tropical Pacific Ocean toward states resembling El Niño and La Niña.

Although still being built, the global VOC network is already yielding insights into how the complex interactions associated with these organic chemicals influence climate and air quality.
October 19th, 2009A team of researchers discovered that biological and chemical changes occurring at a remote Arctic lake in recent decades are unprecedented over the past 200,000 years and the result of human-caused climate change. Their record of past environments goes back in time 80,000 years before the oldest reliable ice cores from Greenland and captures three interglacial periods, including the Holocene. But changes seen in the sediment cores since about 1950 show that expected natural climate cooling and related changes in the lake environment are being overridden by human activity like greenhouse gas emissions.
September 4th, 2009An international team of scientists have reconstructed past climate in the Arctic over the past 2,000 years in unprecedented detail. The team found that Arctic temperatures have reversed from a long-term cooling trend and are now the warmest they have been in at least 2,000 years, bad news for the world’s coastal cities facing rising seas in the coming decades.
August 26th, 2009A new international research effort on the Greenland ice sheet--with Jim White helping lead the U.S. contribution--set a record for single-season deep ice-core drilling this summer, recovering more than a mile of ice core that is expected to help scientists better assess the risks of abrupt climate change in the future.
July 29th, 2009Jim White is one of several CU-Boulder climate scientists featured in videos and other media for a new website called LearnMoreAboutClimate.colorado.edu. The site is designed to engage Colorado citizens in learning about climate and to encourage them to make lifestyle changes.
June 21st, 2009Researchers have produced an exceptionally detailed record of past ice-sheet retreat through a Canadian fjord and, in the process, have provided insight into how present ice sheets in Greenland and Antarctica may thin and retreat with continued global warming.
April 23rd, 2009Vasilii Petrenko (INSTAAR postdoc) led a large international team in developing and applying a new technique for analyzing the carbon-14 content of methane in ancient Greenland ice. Their analyses suggest that a spike in the greenhouse gas methane about 11,600 years ago originated from wetlands rather than the ocean floor or from permafrost, a finding that is good news from a global warming standpoint.
March 17th, 2009Gifford Miller was elected a fellow of the American Geophysical Union for his "pioneering work in dating methods as well as his insights into Quaternary climates and the role of humans in ecological change." Fellowship is bestowed on no more than 0.1 percent of the total AGU membership of about 45,000 in any given year and recognizes scientists who have attained acknowledged eminence in the geophysical sciences.
