Ancient extinction of giant Australian bird points to humans

The first direct evidence that humans played a substantial role in the extinction of the huge, wondrous beasts inhabiting Australia some 50,000 years ago--in this case a 500-pound bird, Genyornis newtoni--has been discovered by a University of Colorado Boulder-led team.

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

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

By 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.
