Arctic in early January 2014

In early January 2014, Arctic sea ice extent reached levels as low as they were in early January 2013, as illustrated by the image below.

Methane levels over the Arctic remain extremely high. The image below shows methane readings for the period January 1 - 11, 2014, with the inset showing the situation in 2013 for the same period.

Similarly, the image below makes a comparison between methane recorded in 2013 and in 2014 for this period (January 1-11), this time focusing on the Arctic and only showing methane readings of 1950 ppb and higher in yellow.

Below a combination of images by Dr. Leonid Yurganov, also comparing methane levels between early 2013 and 2014. The difference isn't as marked in the image below as in the above image, as the highest value in the image below is 1920+ ppb, whereas the above image highlights levels of 1950+ ppb.

These high methane releases from the seafloor of the Arctic Ocean are contributing to the over 20°C temperature anomalies that have hit parts of the Arctic Ocean recently, as illustrated by the image below.

In conclusion, the Arctic is hit by three kinds of warming, while there are at least 13 feedbacks that further accelerate warming in the Arctic, as described in the post The Biggest Story of 2013.
