NSIDC Scientific Expeditions
Scientists blog from Antarctica and provide a glimpse of what it's like to do research in the field. 
What's hot in the news around climate and sea ice and what are scientists talking about now? 
More rain than snow will fall in the Arctic and this transition will occur decades earlier than previously predicted, a new study led by the University of Manitoba (UM) reports.

Mountain and polar groups at the twenty-sixth United Nations Climate Change Conference of the Parties (COP26) are calling for more consideration of the dire global impacts that will result should governments not take greater action as the climate talks in Glasgow begin their second and final week.

Arctic sea ice has likely reached its minimum extent for the year, at 4.72 million square kilometers (1.82 million square miles) on September 16, 2021, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. The 2021 minimum is the twelfth lowest in the nearly 43-year satellite record. The last 15 years are the lowest 15 sea ice extents in the satellite record.

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.
