Sea Ice Extent – Day 10 – 10th Daily Record

There is an amazing phenomenon happening right now that many are unaware of – growth of Antarctic sea ice (relative to long term averages). As the annual Antarctic sea ice minimum approaches, the current anomaly is about a 3 sigma departure from the long term average. The data seems to show that this occurrence is not just a blip, but seems to be part of a tendency over the last decade or more. In fact the trend is currently overwhelming the decline in arctic sea ice (which seems to have stabalized over the last 7 or 8 years). In fact global sea ice extent (arctic and antarctic combined) looks to be around 2 sigma departure above normal for this date! This has important implications for global climate because above normal sea ice reflects sunlight heat energy (like a mirror) that would otherwise be absorbed by ocean waters.

10 daily records in a row in 2015.

Antarctic Sea Ice Extent Breaks Daily Record By 700,000 sq km.

That is 3 standard deviations above normal. In fact every day in 2015 has been above 3 STD.
