Tyler Jones, Brad Markle, and Valerie Morris are leading a group of students in resampling the Greenland Ice Sheet Project Two (GISP2) core to investigate mechanisms of abrupt climate change and extreme events of the past. The original measurements (e.g., water isotopes) numbered a few thousand while the new measurements will create millions of data points.

For the second summer in a row, the CU Boulder Division of Public Safety's Flight Operations department is supporting important campus research in Alaska, as part of the Navigating the New Arctic project (principal investigator: Tyler Jones), which is being managed by researchers in the Stable Isotope Lab of INSTAAR.

Scientists, climbers and local communities come together to warn of the impact of warming on the Himalayas, which is evident when comparing photographs taken over time, and puts the lives of millions of people at risk. Many of the most revealing photographs of the valleys near Everest have been taken by Alton Byers, who has been repeating the photos made by pioneering climbers for years to show the spectacular changes taking place in this region.

The Natural History Museum in Kathmandu revives the ancient art of tracking with an exhibit that includes casts of wildlife tracks made by INSTAAR research scientist Alton Byers.

Seminars at the Mountain Research Station will address the plants, animals, soils, permafrost, fires, and water of the Front Range, and how climate change interacts with all of them. All are welcome to the seminars, which are free and open to the public.

A new paper by a team of USGS and CU Boulder scientists is mentioned in this news story on rivers and streams in Alaska changing color. The streams are turning from blue to rusty orange because of toxic metals released by thawing permafrost and leaching into stream water.

The common mountain bird has an excellent memory for the right perch for free seeds, and has the flexibility to handle climate change. New research from the University of Colorado and colleagues has tightened a claw around the sets of genes that make mountain chickadees some of the most remarkable return-navigators in nature.

Colorado's mountain streams are facing a "real challenge" from a rising concentration of heavy metal levels. These rising levels are only worsening with climate change, a new study found.

A new model makes better predictions of the behavior of ice on Mars鈥攁nd any other rocky planet with an atmosphere.

Warming temperatures are causing a steady rise in copper, zinc and sulfate in the waters of Colorado mountain streams affected by acid rock drainage. Concentrations of these metals have roughly doubled in these alpine streams over the past 30 years, a new study finds, presenting a concern for ecosystems, downstream water quality and mining remediation.
