As well as their main dataset of sea ice extent, NSIDC also have Arctic data from MASIE, (Multisensor Analyzed Sea Ice Extent).

The two datasets are not directly comparable as they are calculated in different ways. In addition, MASIE data only starts in 2006.

Nevertheless, as even NSIDC themselves accept, it is MASIE which is the more accurate product.

When we compare data for 21st Feb, we find that current extent is higher than 2006, 2007, 2011 and 2015:

Moreover, the year with the greatest extent was 2014, and this was only 1.9% higher than this year. Clearly Arctic sea ice is much more stable than we are told.

 

Temperatures in the Arctic have been plummeting this month, so it is likely that sea ice will continue to grow for a while yet.

Methane Bomb Bursts: catastrophic release ‘highly unlikely’

Methane Bomb Bursts: catastrophic release ‘highly unlikely’

via Current News – Principia Scientific Internationalhttp://principia-scientific.org

A new USGS report challenges the consensus belief that a warming climate would lead to an explosive release of methane into the atmosphere from the breakdown of frozen methane hydrates. Climate alarmists like Al Gore have called this the ‘methane bomb,’ where frozen hydrates stored beneath the permafrost and seabed floors warms up, allowing the trapped gas to escape.

Star’s seven Earth-sized worlds set record

Star’s seven Earth-sized worlds set record

via Current News – Principia Scientific Internationalhttp://principia-scientific.org

Astronomers have detected a record seven Earth-sized planets orbiting a single star. The researchers say that all seven could potentially support liquid water on the surface, depending on the other properties of those planets. But only three are within the conventional "habitable" zone where life is considered a possibility.
