Alaska’s top-heavy glaciers are approaching an irreversible tipping point (The Conversation)

July 4, 2024

The melting of the Juneau Icefield in Alaska—one of North America’s largest icefields—has accelerated and could soon reach an irreversible tipping point, according to a paper by Davies et al. published in Nature Communications. Coauthors include Brad Markle of INSTAAR and Geological Sciences. He is also Director of Academics for the Juneau Icefield Research Program.

Old core, new data: Students unlock knowledge about past Arctic climates

June 27, 2024

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.

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.
