Overview
It is likely the Arctic sea ice extent has reached its minimum for the year which is slightly higher than last year’s level and well above the record minimum amount observed in 2012. Temperatures in the Arctic region during the just ended summer season continued to follow a very consistent pattern of recent years, measuring nearly normal to slightly colder than normal. It is the temperatures in the summer months of June, July, and August which are critical when it comes to Arctic sea ice extent as this is the melting season up in that part of the world. Arctic sea ice extent has been running at below-normal levels since the middle 1990’s; however, it has shown resiliency for the last dozen years or so both in terms extent and in volume. One possible explanation of this persistent temperature pattern across the Arctic region featuring nearly normal to slightly below-normal levels in the summer season and warmer-than-normal conditions during the coldest nine months of the year is the increased levels of water vapor in the atmosphere.
