The Arctic area experiences a pure freeze-thaw cycle all through the summer season and winter months. Being that such modifications are half of a pure cycle, please clarify 1) what’s the urgent situation related to sea ice extension in the Arctic. You’ll want to use your individual phrases (no cut-and-paste) and 2) clarify why we have to pay particular consideration to this situation. If useful, please confer with particular years that have been thought-about very uncommon for sea ice extension that made the scientific group deeply involved (bonus level).
