Each September, the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder informs the public of the annual Arctic sea ice minimum extent, an indicator of how climate change is affecting the Arctic, the fastest-warming region of the globe.

Scientists at Northern Arizona University, Arizona State University, the Arizona Geological Survey at the University of Arizona, and the National Snow and Ice Data Center at the University of Colorado Boulder have been awarded almost $2 million from the National Science Foundation (NSF) to develop a virtual reality teaching tool called Polar Explorer.

The National Snow and Ice Data Center (NSIDC) announced this week their participation in the 50x30 Coalition, a group of governments and cryosphere and emissions research institutions endorsing the need to reduce greenhouse gas emissions 50 percent by 2030. The Coalition’s founding members endorse the scientific consensus that failure to reach this milestone will result in temperature “overshoot,” in which emissions remain too high to hold Earth within 1.5 degrees Celsius of pre-industrial levels, leading to major and irreversible damages to the environment. Damage may be especially harmful for highly temperature-sensitive frozen components of the Earth system, with impacts ranging from sea level rise to infrastructure damage to food insecurity.

Arctic sea ice has likely reached its maximum extent for the year, at 14.77 million square kilometers (5.70 million square miles) on March 21, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 maximum is tied with 2007 for seventh lowest in the 43-year satellite record.

With support from NASA, the NSIDC DAAC now offers an interactive tool called IceFlow that harmonizes and standardizes lidar data into a uniform format, allowing scientists to analyze significant changes within the cyrosphere.
