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? 
The Arctic is warming twice as fast as the rest of the world, and sea ice loss plays a large role in this. While warmer conditions lead to more melting of sea ice, the loss of sea ice also makes it warmer - a vicious feedback cycle.
