📢 Shout-out to Megan Thompson-Munson, Jen Kay, & INSTAARite Bradley Markle for their new study of how Greenland's firn responds to temperature changes. ICYDK, firn is the porous transitional material between ❄️ fresh snow & 🧊 glacial ice. Go team! 🙌🏽

A new CIRES and -led study found Greenland's "firn" - the spongy layer between ice and snow - is more sensitive to warming than cooling. The paper was led by CIRES and PhD graduate and CIRES Fellow Read the story: https://cires.colorado.edu/news/warming-has-more-impact-cooling-greenlands-firn

2 bird species just became 1?

Based in part on a 2021 Nature Comms publication led by the Taylor Lab at the University of Colorado Boulder, the American Ornithological Society has officially lumped 2 redpoll finch species. Despite their different looks, few genetic differences exist between them

The redpoll finch saga: How two bird species just became one The American Ornithological Society reclassified two previously distinct species of finch as one, based on genetic research by CU Boulder scientists. The move knocks one name off birders’ “life list” and raises questions about what a species really is.

🕯️In Memoriam: HARIHAR RAJARAM
He was a kind & open-minded scientist + a good friend & collaborator with many INSTAARs (snow, ice, hydrology, & many more topics). He started at the University of Colorado Boulder in 1993 & moved to the Whiting School of Engineering at Johns Hopkins University in 2018. His passing is a great loss.

Renowned environmental and earth systems researcher Harihar Rajaram dies at 59 Remembered as a dedicated mentor, Rajaram was known for his innovative use of mathematical models to understand and predict complex environmental phenomena
