This week, scientists here at the Fall Meeting of the American Geophysical Union rolled out their 18th version of the Arctic Report Card, a series of essays and data about environmental changes on top of the world put together by people at the National Oceanic and Atmospheric Association and featuring the work of many Alaska scientists.
