Arctic Breaks Many Records – Arctic Report Card 2016

Since 2006, the National Oceanic and Atmospheric Administration (NOAA) has issued an annual peer-reviewed assessment of the Arctic. The tenth assessment was released on December 13, 2016.  Arctic Report Card 2016 is remarkable for two reasons.

Likely contributing factors were unusually warm air brought up from mid-latitudes and sea surface temperatures near the ice margins that were far above normal for this time of year.  All of the jaw dropping (at least to this scientist) charts and statistics in this report add up to multiple lines of evidence – ‘vital signs’ – that point to a diagnosis.  As stated in the report: “Persistent warming trend and loss of sea ice are triggering extensive Arctic changes.”  We know what the primary cause of the persistent warming trend globally is – burning coal, oil, gas and deforestation.  The Paris Climate Agreement aims to put the breaks on that global trend.

Beyond the charts: Yupik word for type of sea ice that is extremely rare to observe today

The report card includes a story recounted by Brendan Kelly, Executive Director of the Study of Environmental Arctic Change (SEARCH) that gets to the heart of the jaw-dropping charts of plummeting sea ice age for greater proportions of the Arctic.  Sea ice thickness, in general, increases with ice age (i.e. how many years the sea ice persists).

He learned dozens of Yupik words for sea ice from Conrad Oozeva, who is from St. Lawrence Island in the Bering Sea.  The Yupik word for thick, dark, weathered ice – tagneghneq – refers to a type of sea ice that is extremely rare to observe today.  Passing on a language to the next generation involves context; it could be difficult to explain the meaning of a word that can’t be easily seen.  This poses a risk to cultural heritage.  While many are taking steps to preserve endangered Alaskan languages, over a hundred countries or parties have already ratified the Paris Climate Agreement.  A significant reduction in emissions behind the global warming trend could mean less warming in the Arctic, and less impact on sea ice. There may still be hope for tagneghneq.

    Falsely attributing the effects of the large El Nino in 2016 to Climate Change is not science, it s the denial of science.

    The ENSO is not Climate, it is Weather.

    They call this science? Vague and unsubstantiated claims that the earth is getting too warm – too fast by comparison to what exactly? If there is no given temperature or rate as a basis, and using the scientific method, how can AGW be proven wrong?

    Nuclear bomb tests took place from 1945 to 1978 (33 years) at a rate of one test every two weeks. Do you think that had anything to do with global warming? Of course it didn’t, and neither does any other man made activity.
