I thought there might be interest in a thread on the Summer arctic ice melt, now that it looks like most every record of minimum ice, in both extent of coverage and volume, on sea and land, look likely to be broken in the next month.

Arctic sea ice looks set to hit a record low by the end of the month, according to satellite data.
Scientists at the US National Snow and Ice Data Center said data showed that the sea ice extent was tracking below the previous record low, set in 2007.
Latest figures show that on 13 August ice extent was 483,000 sq km (186,000 sq miles) below the previous record low for the same date five years ago.
The ice is expected to continue melting until mid- to late September.
"A new daily record... would be likely by the end of August," the centre's lead scientist, Ted Scambos, told Reuters...
this year's projected record minimum could result in a change in projections of when the Arctic would be sea ice-free during summer months.
"The previous [Intergovernmental Panel on Climate Change] report (published in 2007) stated that the likely date for an ice-free Arctic in the summer - and definitions for this vary a bit - was 2100," he explained.
"When we had the 2007 minimum, that date was brought forward to 2030-2040.
"The fact that we look set to get another record ice minimum in such a short space of time means that the modellers may once again need to go and look at what their projections are telling them."

The untold drama of Northern snow cover
When considering the impact of climate change on polar regions, the star of the show has always been Arctic sea ice. Playing supporting roles are the Greenland ice cap and Antarctica. Yet one actor in the drama remains badly overlooked: the snows that cover our Northern continents.
In June 2012, for instance, it was reported that Northern Hemisphere Land Snow Cover had broken a record. The June snow anomaly was the lowest figure for June in the whole 45 year record, besting the previous record set in 2010 by 1 million square kilometres...
