- This fall, sea ice extent was second smallest in Antarctica and fourth smallest in the Arctic. Moreover, sea ice volume was very low in the Arctic. Alexandra Jahn notes that human-caused emissions “are required to get an Arctic sea ice loss as large as observed”.
- A melting glacier collapsed, sending the mountaintop it propped up careening into the Dickson Fjord in East Greenland. The impact created a 650-foot tall tsunami, which crashed back and forth between the steep channel walls. Tyler Jones puts the event into the context of arctic climate change.
- Lauren Magliozzi (CEAE researcher) offers her perspective on what happens to tiny organisms in streams affected by wildfires has meaning for humans, as well. The story told by these streams and their tiny inhabitants is clear: Urban wildfires pose a serious threat to water quality and aquatic life.
- Rapid thawing of the Himalayan ice-cap is compounded by little-studied melting of permafrost that destabilizes peaks, write Wilfried Haeberli and Alton Byers.
- Antarctic krill fishing could threaten the recovery of whale species that were nearly wiped out by industrial whaling, according to a study led by CU Boulder and Stanford University, and published Sept. 10 in the journal Nature Communications. Zephyr Sylvester and Cassandra Brooks were part of the research team.
- An atmospheric river brought warm, humid air to the coldest and driest corner of the planet in 2022, pushing temperatures 70 degrees above average. Mike Gooseff and Anna Wright were part of a study revealing what happened to Antarctica’s smallest animals.
- A team of scientists led by CU Boulder has identified 30 new areas critical for conserving biodiversity in the Southern Ocean surrounding Antarctica. The researchers warn that without greater protection to limit human activities in these areas, native wildlife could face significant population declines. The team was led by Sarah Becker and includes Cassandra Brooks.
- Graduate student Airy Gonzalez Peralta grew up far from pika habitat. Now she strives to understand how climate change could affect these adorable mountain mammals. Join her on a multimedia journey to her pika research site on Niwot Ridge, Colorado and the backstory on how she ended up there.
- From 2007-2022, renowned photographer (and INSTAAR Affiliate) James Balog documented glacial change around the world in real time via timelapse imagery through a project called the Extreme Ice Survey. 1.5 million images from the project are now stored and managed at the National Snow and Ice Data Center.
- New research suggests that the North Atlantic subtropical gyre may have been much stronger and deeper during the Last Glacial Maximum, despite the prevailing cold climate and presence of ice sheets. Tom Marchitto was part of a research team led by Jack Wharton of University College London.
