NOAA has released this year's Arctic Report Card.
What's new in 2013?
There were fewer snow and ice extremes than in 2012. Many regions and components of the Arctic environment were closer to their long-term averages, but the effects of a persistent warming trend that began over 30 years ago remain clearly evident.
The impacts of the warming climate on the physical environment during those 30 years are influencing Arctic ecosystems on the land and in the sea.
Here's a video accompanying the report:
And a longer video showing the press conference announcing the report at the 2013 AGU Fall Meeting, last Thursday:
Climate Central's Andrew Freedman, who was present at the press conference to ask questions, has another excellent summary of the report here.
