ARCUS June Sea Ice Outlook The New Normal Posted on June 21, 2012 by Anthony Watts
From ARCUS: Im late getting this posted, apologies. WUWT comes in third highest, same position we were last year. My thanks to Helen Wiggins for allowing us to enter again this year. Anthony
With 19 responses for the Pan-Arctic Outlook (plus 6 regional Outlook contributions), the June Sea Ice Outlook projects a September 2012 arctic sea extent median value of 4.4 million square kilometers, with quartiles of 4.3 and 4.7 million square kilometers (Figure 1). This compares to observed September values of 4.6 in 2011, 4.9 in 2010, and 5.4 in 2009. Both the 2012 quartile values and the range (4.1 to 4.9) are quite narrow. The 2012 June Outlook differs from all previous Outlooks in that there are no projections of extent greater than 5.0. It is always important to note for context that all 2012 estimates are well below the 19792007 September mean of 6.7 million square kilometers.

Individual responses are based on a range of methods: statistical, numerical models, comparison with previous rates of sea ice loss, composites of several approaches, estimates based on various non-sea ice datasets and trends, and subjective information. The consensus is for a continued downward trend of September sea ice. It seems that the time may have come to declare that the arctic sea ice has in fact reached a New Normal. The physical justification for this statement is based primarily on the loss of old, thick sea ice and the increased mobility of sea ice. An expanded discussion of sea ice age and thickness is included in this months full report, which includes new sea ice thickness data from NASA IceBridge aircraft flights in MarchApril 2012.

You are aware are you not that there is always a summer sea ice melt.

Early cartographers were unsure whether to draw the region around the North Pole as land (as in Johannes Ruysch's map of 1507, or Gerardus Mercator's map of 1595) or water (as with Martin Waldseemüller's world map of 1507). The fervent desire of European merchants for a northern passage to "Cathay" (China) caused water to win out, and by 1723 mapmakers such as Johann Homann featured an extensive "Oceanus Septentrionalis" at the northern edge of their charts.
The few expeditions to penetrate much beyond the Arctic Circle in this era added only small islands, such as Novaya Zemlya (11th century) and Spitsbergen (1596), though since these were often surrounded by pack-ice their northern limits were not so clear. The makers of navigational charts, more conservative than some of the more fanciful cartographers, tended to leave the region blank, with only fragments of known coastline sketched in.
This lack of knowledge of what lay north of the shifting barrier of ice gave rise to a number of conjectures. In England and other European nations, the myth of an "Open Polar Sea" was persistent. John Barrow, long time Second Secretary of the British Admiralty, promoted exploration of the region from 1818 to 1845 in search of this."

Yeah. Everybody went swimming in the Arctic in Summer to escape the heat.....;}
We dont have enough long-term data to say what is usual with regard to ice coverage in the arctic or understand the full extent of its natural variation.

According to pollen-based climate reconstructions, summer temperatures and annual precipitation during the super interglacials were about 4 to 5 degrees C warmer and about 12 inches (300 mm) wetter than during normal interglacials. The super interglacial climates suggest that it's virtually impossible for the Greenland's ice sheet to have existed in its present form at those times.
Simulations using a state-of-the-art climate model show that the high temperature and precipitation
during the super interglacials cannot be explained by Earth´s orbital parameters or variations in atmospheric greenhouse gases alone,
************which geologists typically see driving the glacial/interglacial pattern during ice ages. This suggests additional climate feedbacks are at work. **************************
The scientists suspect the trigger for intense interglacials might be in Antarctica.
Earlier work by the international ANDRILL program discovered recurring intervals when the West Antarctic Ice Sheet melted. The current study shows that some of these events match remarkably well with the super interglacials in the Arctic.
ScienceDaily (June 21, 2012) Intense warm climate intervals--warmer than scientists thought possible--have occurred in the Arctic over the past 2.8 million years.
That result comes from the first analyses of the longest sediment cores ever retrieved on land. They were obtained from beneath remote, ice-covered Lake Elgygytgyn (pronounced Elgee-git-gin) (Lake E) in the northeastern Russian Arctic.

Since you like fire so much, here is some to consider:
Hebrews Chapter 12:
1 Therefore we also, since we are surrounded by so great a cloud of witnesses, let us lay aside every weight, and the sin which so easily ensnares us, and let us run with endurance the race that is set before us, 2 looking unto Jesus, the author and finisher of our faith, who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God. 3 For consider Him who endured such hostility from sinners against Himself, lest you become weary and discouraged in your souls. 4 You have not yet resisted to bloodshed, striving against sin. 5 And you have forgotten the exhortation which speaks to you as to sons: "My son, do not despise the chastening of the Lord, Nor be discouraged when you are rebuked by Him; 6 For whom the Lord loves He chastens, And scourges every son whom He receives." 7 If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? 8 But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons. 9 Furthermore, we have had human fathers who corrected us, and we paid them respect. Shall we not much more readily be in subjection to the Father of spirits and live? 10 For they indeed for a few days chastened us as seemed best to them, but He for our profit, that we may be partakers of His holiness. 11 Now no chastening seems to be joyful for the present, but painful; nevertheless, afterward it yields the peaceable fruit of righteousness to those who have been trained by it. 12 Therefore strengthen the hands which hang down, and the feeble knees, 13 and make straight paths for your feet, so that what is lame may not be dislocated, but rather be healed. 14 Pursue peace with all people, and holiness, without which no one will see the Lord: 15 looking carefully lest anyone fall short of the grace of God; lest any root of bitterness springing up cause trouble, and by this many become defiled; 16 lest there be any fornicator or profane person like Esau, who for one morsel of food sold his birthright. 17 For you know that afterward, when he wanted to inherit the blessing, he was rejected, for he found no place for repentance, though he sought it diligently with tears. 18 For you have not come to the mountain that may be touched and that burned with fire, and to blackness and darkness and tempest, 19 and the sound of a trumpet and the voice of words, so that those who heard it begged that the word should not be spoken to them anymore. 20 (For they could not endure what was commanded: "And if so much as a beast touches the mountain, it shall be stoned or shot with an arrow." 21 And so terrifying was the sight that Moses said, "I am exceedingly afraid and trembling.") 22 But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, 23 to the general assembly and church of the firstborn who are registered in heaven, to God the Judge of all, to the spirits of just men made perfect, 24 to Jesus the Mediator of the new covenant, and to the blood of sprinkling that speaks better things than that of Abel. 25 See that you do not refuse Him who speaks. For if they did not escape who refused Him who spoke on earth, much more shall we not escape if we turn away from Him who speaks from heaven, 26 whose voice then shook the earth; but now He has promised, saying, "Yet once more I shake not only the earth, but also heaven." 27 Now this, "Yet once more," indicates the removal of those things that are being shaken, as of things that are made, that the things which cannot be shaken may remain. 28 Therefore, since we are receiving a kingdom which cannot be shaken, let us have grace, by which we may serve God acceptably with reverence and godly fear. 29 For our God is a consuming fire.
