A landscape unseen in over 40,000 years

January 25th, 2019Glacial retreat in the Canadian Arctic has uncovered landscapes that haven’t been ice-free in more than 40,000 years, and the region may be experiencing its warmest century in 115,000 years, new INSTAAR-led research finds. The study, published today in the journal Nature Communications, uses radiocarbon dating to determine the ages of plants collected at the edges of 30 ice caps on Baffin Island, west of Greenland.

Less ice, more water: New research shows parts of Arctic Ocean rapidly shifting conditions

November 2nd, 2015By the 2050s, parts of the Arctic Ocean once covered by sea ice much of the year will see at least 60 days a year of open water, according to a new modeling study led by Katy Barnhart of INSTAAR. Barnhart and her colleagues, including CIRES Fellow Jennifer Kay and INSTAAR Fellow Irina Overeem, set out to investigate the very local impacts of open water expansion patterns in the Arctic. Their work is published today in the journal Nature Climate Change. The researchers used climate model simulations from the National Center for Atmospheric Research-based Community Earth System Model to see how the number of open water, or sea-ice-free, days change from 1850 to 2100 in our planet’s northernmost ocean. They also wanted to understand when open water conditions in specific locations would be completely different from preindustrial conditions.

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.
CU-led mountain forest study shows vulnerability to climate change

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.

New climate study may answer long-standing questions about Little Ice Age

January 30th, 2012A new study led by INSTAAR Fellow Gifford Miller appears to answer contentious questions about the onset and cause of Earth’s Little Ice Age, a period of cooling temperatures that began after the Middle Ages and lasted into the late 19th century. According to the study, the Little Ice Age began abruptly between A.D. 1275 and 1300, triggered by repeated, explosive volcanism and sustained by a self-perpetuating sea ice-ocean feedback system in the North Atlantic Ocean.

10,000-year-old hunting weapon found in a melting ice patch of the Rocky Mountains

July 20th, 2010To the untrained eye, Craig Lee's recent discovery of a wooden hunting weapon might look like a small branch that blew off a tree in a windstorm, but nothing could be further from the truth. Radiocarbon dating showed that the dart is 10,400-years-old, making it the oldest artifact ever discovered melting out of ancient ice. Its age and preservation provide a unique window into late Paleoindian society, including its technology, social protocols, and high-altitude subsistence practices.

Alaska glacier speed-up tied to internal plumbing
January 18th, 2008Masters student Tim Bartholomaus with Bob and Suzanne Anderson have published their work on the sliding of Alaska's Kennicott Glacier.
