There’s an old saying …
I’m thinking of this one.
There are those that do,
There are those that don’t,
There are those who wondered what happened!
So what prompted me bringing out that old saw?
Simply the ever-increasing rate of the loss of our Arctic sea ice.

The Guardian jumps the gun on record June sea ice melt
29 Jun 2012, 11:15 – Verity Payne
The Guardian this week reports that recent rapid melting of Arctic sea ice has seen levels reach a “record low for June”. But it’s premature to be heralding June 2012 as having record low Arctic sea ice extent before the month is even over, particularly as sea ice extent is not currently tracking at record low levels.
The Guardian article says Arctic sea ice “has melted faster this year than ever recorded before”, under the online headline “Arctic sea-ice levels at record low for June”.
This headline could be read in two ways. The first interpretation is that Arctic sea ice extent for the month of June is at a record low. But can we know that before the month is out? The second is that at some point in June Arctic sea ice was at a record low. But does highlighting a few days of sea ice behaviour best illustrate what’s happening to the sea ice?
The piece also appeared in the print version of the Guardian yesterday with the headline “Arctic sea ice has melted faster than ever, say scientists”.
The Arctic sea ice is in long-term decline due to man made climate change, but it’s not a uniform decline – sea ice cover changes with the seasons, and the weather in the region affects how far the sea ice extends, particularly as it melts towards the ice minimum in late September.
During melt season, Arctic sea ice seems to get a lot of media attention, often with rather confusing results. This Guardian article was prompted by analysis from the US National Snow and Ice Data Center (NSIDC), who provide daily updates and regular analysis of Arctic sea ice conditions.
The mention of that Guardian Newspaper article is worth clicking through to, if only to enjoy the fabulous photograph, as below:

Rapid sea ice retreat in June
Arctic sea ice extent declined quickly in June, setting record daily lows for a brief period in the middle of the month. Strong ice loss in the Kara, Bering, and Beaufort seas, and Hudson and Baffin bays, led the overall retreat. Northern Hemisphere snow extent was unusually low in May and June, continuing a pattern of rapid spring snow melt seen in the past six years.
Overview of conditions
Arctic sea ice extent for June 2012 averaged 10.97 million square kilometers (4.24 million square miles). This was 1.18 million square kilometers (456,000 square miles) below the 1979 to 2000 average extent. The last three Junes (2010-2012) are the three lowest in the satellite record. June 2012 ice extent was 140,000 square kilometers (54,000 square miles) above the 2010 record low. Ice losses were notable in the Kara Sea, and in the Beaufort Sea, where a large polynya has formed. Retreat of ice in the Hudson and Baffin bays also contributed to the low June 2012 extent. The only area of the Arctic where sea ice extent is currently above average is along the eastern Greenland coast.

That old saying that I opened with, the one about There are those that do, etc.
No question in my mind that firmly in the camp of those that do is Mother Nature! Anyone prepared?
