The Arctic sun has now passed its peak, and is starting its decline towards the horizon over the next 90 days.
All four (JAXA NSIDC DMI NORSEX) ice extent measurements now show 2010 as below 2007. You can see in the modified NSIDC map below that the regions which are below the 30 year mean (marked in red) are all outside of the Arctic Basin and are normally ice free in September, so it is still too early to make any September forecasts based on extent data.
The modified NSIDC map below shows ice loss (in red) during the last nine days. There has been very little change in the Arctic Basin.
The modified NSIDC map below shows ice loss (in red) since early April. According to JAXA, this is about 5 million km².
The modified NSIDC map below shows ice loss (in red) since early April. According to JAXA, this is about 5 million km².
The modified NSIDC map below shows ice loss (in red) since 2007. According to JAXA, this is about 500,000 km². Areas in green have more ice than 2007.
There has been a strong clockwise rotation of wind in the Beaufort Gyre, which is pulling ice away from the land around the edges of the Beaufort, Chukchi and East Siberian and Laptev Seas.

The video below shows changes in PIPS ice thickness and extent during June. You can see the ice rotating clockwise and concentrating in the center of the Arctic Basin.
During the last 10 days, PIPS shows that Arctic Basin ice volume has dropped close to 2007 and 2009 levels. Volume has increased by about 40% since 2008.
Average ice thickness is now the highest for the date during the last five years. This is due to the compression of the ice towards the interior of the Arctic Basin.
Ice offshore of Barrow, Alaska is showing little signs of melt so far.

The current break up forecast calls for July 5.

Temperatures north of 80N have been persistently below normal this summer.
http://ocean.dmi.dk/arctic/plots/meanTarchive/meanT_2010.png
There are still no signs of melt at the North Pole, with temperatures running right at the freezing point – and below normal. Normally there has been surface melting for several weeks already.

Arctic Basin ice generally looks healthier than 20 years ago.
I’m forecasting a summer minimum of 5.5 million km², based on JAXA. i.e. higher than 2009, lower than 2006.
Meanwhile down south, Antarctic ice is well above “normal” close to a record maximum for the date.

The video below shows the entire NSIDC Antarctic record for the last 30 years.It looks like a heart beating














Interesting claim about sea ice volume being above 2008.
How do you reconcile it with the chart at
http://nsidc.org/images/arcticseaicenews/20100608_Figure5.png
which shows an increase in the anomaly over 2008?
Arctic ice volume has not recovered, and is not healthy.

Lighten Up.
This is the Best SCIENCE site on the web because people throw Graphs & Charts at each other.
If we start to throw chairs: that’s a problem.
Science is about Questioning.
Both sides have to try REAL HARD.
A lot of this is about Questioning Sources — & some do not hold up.
Other sites just say “you can’t listen to them”.
…But they then give NO DETAILS.
Example: People will say: ‘GISS is awful. Here I’ve seen: Look at these Charts from Goddard/GISS versus Others’ – – or even one of GISS’s own.
GISS really is in charge Only of USA surface Data & has been quite good at REVISING their Results when, say, outsider Steve McIntyre challenged the demotion of 1934 as the USA’s hottest year. Globally, though, they accept Everything for the rest of the Globe, from the IPCC(even though Hansen’s hissed: “tenths of a degree, TENTHS OF A DEGREE ! ” on the Letteman Show indicated even HANSEN personally prefers the Satellite Data over the Global Surface Temps his own GISS site features – – but there Is no other SURFACE Data Set for the Globe, since they Hijacked the Old sets sent to Sir Issaac Newton’s Greenwich for centuries, and Locked them in the Vaults of East Anglia University ). And, GISS makes these Glitzy Presentations which, when you click on their High Resolution maps of the Arctic: you see just a couple little spots & blank Space — they are just bridging Data from 2 or 3 sites (Eureka, Spitzbergen) over the Whole Arctic – – most of the European ones showing Temp DECREASES somehow got Closed, or excluded from the IPCC maps (like most of Canada).
Currently: Steve Goddard is into – – Anything new that OPPOSES A BIG-MELT.
That’s his JOB (scientifically).
Every ICE Index was Up in March, & He looked Good.
Now every Extent, Area & Volume site is not just Low, but RECORD LOW except 2 of the 4 NORSEX charts ( both of which lines are now TOUCHING the 2007 record line ), and an index he put together recently – – his Pips-derived Volume.
And.TomP recalculated that …
– – though I want to see TomP’s Calculations, especially How he got it — not just the end Product.
By the way, Tom’s Graphs were a Treasure: If I missed his Calculations/ and/ot Method, can anyone point to it ?
Steve put his Pips Method out.
And …
I roasted him for it.
Well, parts of it.
But it’s what you are SUPPOSED TO DO.
Everything on the line.
Nothing Held back.
But in CLOUDS, Steve has the Hot Hand.
More CLOUDINESS could REVERSE the slides in every Indexes.
And though I always mentioned it as 1 of 3 Parts of the 2007 Melt – & the one I was uncertain of …
– – Steve FOUND A SITE WITH CURRENT DATA & A Forecast of LESS Sunshine coming up.
He even enlightened us about Cloud Forecasting’s Reliability – – which is:
– – that it Ain’t.
The El Nino is fading (see http://www.drroyspencer.com, as above)
.. maybe the Clouds will win.
You better have a sense of Humor when you forecast the WEATHER.
Kelly Manning,
Steve has already debunked that graph in one of his posts. Skeptics have adequately found the flaws in Global Warming, now it’s your turn.

GettingWarm,
I’m sure you believe in the propaganda about CO2. Posting Regg’s comments onto this board, when it was clearly debunked by Steve Goddard. Nice work Steve!

Please tell us how you differentiate compaction from expansion.
Pardon me for being a skeptic about the “arctic ice mass is increasing theory”, but the last time Mssr. Goddard had a disgreement with NSIDC he turned out to be working with incorrect assumptions.
On the other hand sailors who navigated the arctic last winter reported that what >zero year ice they saw was rotten. What is “rotten ice”? One ice breaker which has a top speed of 13.7 knots in clear water got slowed all the way down to 13 knots in rotten ice.
Looks like the McLure – Parry deepwater northwater passage is well on the way to opening up this summer. The Canadian Ice Service shows sea ice concentration down from 90% to 35% since May 14.

Goddard’s comment about the solstice being past could mislead uninformed readers into thinking that the melt season is over. In fact it is just moving into high gear. The maximum melt point is usually in September, sometimes stretching into October.
When the Manhattan tried ramming through McLure – Parry in September 40 years ago it got stuck repeatedly in 20 meter pressure ridges. The world has changed, in our lifetimes.
Kelly Manning
You seem confused. I correctly pointed out a discrepancy between UIUC and NSIDC in 2008, and UIUC has since made a couple of corrections to their maps as a result. But if you feel the need to spread misinformation about other people, that is your personal problem.
Julienne, I quite understand the temperature gradient. That includes trade winds and the Coriolis effect.
Might we agree on a null hypothesis basis? Understanding solar radiation, Coriolis, GPS topography, our overall stratified atmosphere, and seasonal axis tilt parameters to be relatively constant, Earth’s climates are a function of a chain comprised of natural weather systems generated over trade wind warmed, neutral or cooled oceans and especially equatorial oceans, then further impacted by topography over land areas. This chain is impinged upon by natural internal energy oscillations in these links that lead to long and short periods of weather pattern variability change.
Now add just the human source increase in CO2 to the above. With respect, tell me (see below for discussion ideas) how the human sourced increase in CO2 concentration has somehow developed more power than natural parameters on this chain (IE disprove your null hypothesis).
As a side note in this debate re: your concern over my manners on this blog. Your fall back argument to send me back to some basic textbook is not good debate technique, does not prove your case, and is far more disrespectful than my questioning of your beliefs.
So I challenge you to make a clear explanation about both potential drivers (the natural chain, and human sourced increase in CO2) of weather pattern variability change. By explaining your position on both, (you must rule out other potential causes of your hypothesis in order to develop your position into a theory) you will have made a stronger statement:
Human Sourced CO2 driver
1. Human sourced CO2 increase has changed SST’s through LW re-radiation increase, which in turn has disrupted the temperature gradient, which in turn has changed oceanic and weather systems, thus warming the Arctic ocean, as well as other oceans, yes or no, and if yes, how: state mechanism/mathematical proof, and show historical data graphs of these parameters.
2. Human sourced CO2 increase has changed land/air temperatures through LW re-radiation increase which in turn has disrupted the temperature gradient, which in turn has changed oceanic and weather systems, yes or no, and if yes, how: state mechanism/mathematical proof, and show historical data graphs of these parameters.
The Null Hypothesis: Natural intrinsic random and oscillatory drivers
1. Natural oscillations (which include the extremes of these oscillations), both long and short term, drive oceanic SST and weather pattern variability change, yes or no, and if yes, how (state mechanism/mathematical proof, and show historical data graphs of these parameters).
In order to prove your hypothesis, you must examine and prove/disprove the entire chain of events at each link on both sides of the debate, or else your hypothesis is still null.
So we are faced with three scenarios:
1. If CO2 proves to be more powerfully correlated with observed data at each link, the hypothesis is not null.
2. If both drivers are equal in correlation at each link, the hypothesis is null.
3. If natural variation is more strongly correlated than CO2 at each link, the hypothesis is null.
Correction
I talked a lot about eating Crow
— time to chow down.
I redid my superimposing of the Current-PIOMAS chart onto the “ICESAT & PIOMAS Compared” chart. In the opposite direction. Seems I’d lost the “-10” label on the scale for “Current-PIOMAS” , so the “Zero” of the Current-PIOMAS Chart should be:. Zero = 14,200, & it’s June 18 number was -10,700. It does not affect the “Ice-Left-Above-Zero” which is the Prime Output, but I took the trouble to refine my readings:
I thus reduce by 100 km3 the “Anomaly” = the amount below normal on June 18, which if applied to the September minimum, works out to = 3500 km3 (Previous record 5250, last year 5800).
The Drop rate is revised by 3% = 324 km3 per week
Zero Date forecast is now 10.7 weeks not 11.
Thus my Conclusions are unaffected, the changes are just Refinements – – but one never likes to see errors. .
The LASER Measurements from ICESAT and ICEBRIDGE … were unaffected.
Let me Re-Do My Chart, benefitting from doing the superimposition both Forwards and Backwards … both Original Charts at::
In km3 above Zero Ice (exc: Piomas Coordinates measure: Down from Average)
————- ICESAT / PIOMAS /////// ——- ICESAT
———— In total Ice @ur momisugly minimum ////// Coordinates on PIOMAS-Current:

ZERO ICE LEFT @ur momisugly– 0 —– 0 —–////////// (for Spt 8) = -14,200
2010 April to June = 62-days fell 6400 to 3500 = LOSS OF 2900 km3
= LOSS RATE of 327.4 km3 lost/week = 10.7 weeks left
Notes: ICESAT & ICEBRIDGE Measure Ice with Lasers
Piomas Calibrates Relative Ice with Shore stations, Ships etc. & Icebridge Airplane Lasers for the Central Arctic
Without Icebridge, as in 2007, melting FAR FROM SHORE causes heat to rise which the non-Laser MW Satellites cannot tell from HEAVY ICE, reflecting MORE SUN. It’s still accurate, but by late July will be UNDERESTIMATE ICE LOSS.
2007 Spt-Nov gain, revised from 750 to 950
… all units are: cubic km ( “km3” )
d = DERIVED from ICESAT’s November 6000, by subtracting Piomas’s Spt-to-Nov gain
P+I = Piomas + Icebridge Laser Measured Thickness
PIOMAS CAVEAT:
Piomas begins with the crude readings of MW Satellites and CALIBRATES THAT with EXACT MEASUREMENTS from Shore stations, Ships etc. – – & Icebridge Airplane Lasers for the Central Arctic.
As of May: NO ICEBRIDGE.
Without Icebridge, as in 2007, melting FAR FROM SHORE causes heat to rise which the non-Laser MW Satellites cannot tell from HEAVY ICE, reflecting MORE SUN. It’s still accurate now, but by late July IF the central Area is Opening, about a quarter of the Ocean will Appear to ADD ICE WHERE THERE IS ONLY OPEN WATER.
As in 2007, this can/will result in a sudden Gross UNDERESTIMATION.
Mercator does an Ice Thickness that is a Piomas WITHOUT the Calibrations::.
NB: it does not show Open Water Lakes = polynnyas, where it should.
Pips 2.0 is even more crude (Mercator adds Buoy data every 2 weeks), but Manually adds the Open Water “Polynnyas”.
You can see the “trade-off” between Accuracy & Timeliness:
Pips = 1 / day.
Mercator = 1day & 14 days ….. accuracy declines radically after the 14-day update.
PIOMAS = 21-day updates.
LASERS (ICESAT & Icebridge) took a month to cover the Arctic in very narrow strips.
Therefore ICESAT did 2 months, & analysts interpolated a rate-of-change so they could adjust all PARTS of the Arctic as if the readings were taken on the same day = March 1 & November 1, until early 2008 when it failed & ICEBRIDGE airplanes took over.
Until the Europeans put up Cryosat II, a Laser satellite.
But they won’t tell anyone what it says.

——————————————————————————————–
What’s going on here with most (I didn’t say all) antagonistic commentors here is not science. One reason I know that is because come September when Arctic ice does not shrink as much as these certain antagonists think it will they will disappear. If they really did care about ‘science’ they would always be here giving their viewpoint. But I’m pretty sure most of them are just repeating things they read on a blog somewhere and don’t really know what they are doing.
Re: Amino Acids in Meteorites
Well, I generally just read this site …
I Comment a lot now because I think it’s an Emergency. … Possibly.
But even “just” a 1-in-4 to 1-in-8 chance of Personal Death of ME, gives a lot of incentive.
I’ll write on something else if it is more Dangerous.

(Arrrgh)
Years ago, I determined to Assess ALL major Threats (e.g. Nukes, etc.) Here are two I wrote several years ago:
/ = means Divided by:
(a)ABRUPT CHANGE DAMAGE : 10% of Abrupts times $700,000 B loss to USA ( = most of people killed, etc. )
+ other 90% of Abrupts ~ = not 9 times, but say: equal to that = $ 140,000 Billion per Abrupt Change
(b) SMOOTH CHANGE Change Damage = Farmers have to move, etc. = $ 500 B.
Time at Risk ———————————————- next 33.3 years ————————–
next 33.3 years: Risk Arctic Sea
(a) = 1% x .$ 140,000 Billion/33.3 years = $ 420 B/year (1 big Disaster)
(b) = 100% x $ 500 B / 33.3 years = $ 15 B/year ( weather change )
[ PS … (b) is: that I felt the Lack of Ice: drying out the Tran-Mississippi: was near Certain,
but Melting off ALL in 1 Year & so inducing Ocean Current Reversals & 300 mph winds
= 1% overall = 1 in 3300 EACH year (1 in 3330) – – – I guess we hit the Un-Jackpot ]
Risk: 50 years General Warming = 1% Abrupt Change over first 50 years,
(Each Successive 50 years = 3% , then 6%, 10, 20, 30, 50%) $ = that % times
(a) __ % x $ 140,000 B. /50 years = % of DISASTER = $28 B/year for 1% , etc.
(b) __ % x $ 500 B/50 years = Gradual changes BUT TIMES 10 AS REPEATED CHANGES = $ 1 B/yr.
[As you can see, This was my ANTI-AGWer argument – – I felt the other problems — $29 B — too small for the 100s of Billions/year to solve them
— the Arctic ? $ .02 Billion for a Sulfur Hose looked fine by Me. A 21,000:1 return on investment. PS: I like to refer to $20 million as 2 Billion cents. Keeps everything in the same Units.
Here’s the full list] :
Disasters Rated: ($Billion Dollars per year, Average)
1. $2700 Billion [ /year ] = Atlantic Bomb (ie 270,000 /1% chance PER YEAR)
— Solution: better Satellites
[PS: or, had we Not already done so: INVADE IRAQ — years later, a shame-faced French study found Niger’s buyer REALLY WAS Iraq ! — that is where all Sadaams Foreign Exchange we all assumed would buy Raw Material for the Chemical Factories went — we found the factories — fighting for them for over a year after the invasion. He did not turn into a Nice Guy — he just Concentrated his ca$h on the MAIN, CENTRAL NECCESSITY. . His secondary source for Raw Uranium was Iran, with all those mines & more material than they can even low-level refine. Thus NO invasion of Iraq, & the East Coast would Already be dead. Since he HAD the X-ray mirrors to detonate an H-bomb & then this higher temperature detonates ALL the Raw Uranium, ie all the U-238 too, & his was the Only fruity country with this capability, HE was the USA’s biggest Risk by several THOUSAND times. At the time, it was thought Libya was 80% plus & Iraq only a 10% possibility, but: Libya had been “purging” itself for 2 years, Iran had so much they weren’t buying, & N.Korea didn’t have the Money: SURPRISE.: GWBush did something RIGHT. I guess that makes 1. But a BIG one. ]
2. $2100 B/yr = 10-30 H-Bombs over U.S. cities
— Solution: BOOST Phase SDI
[ PS: I wanted to make it JOINT, with Russia. They’ve already offered to PAY for Radars in a Joint Defense, as part of their Opposition to GWB’s ‘Defense of Europe – – ONLY’ ABM plan. ]
3. $1400B/yr = Present Value of missed Growth from Science Cuts
— +$50-80 Billion/year non-classified Research
–Space/Science solves #1 saving 2700, #3 saving 1400, #4 =1050, 800, 400, 2 of the ca.200’s, 82 + helps #2=2100 & #8=600
4. $1050 = Super-Disease
— Space Colony to solve 100 times faster + Ground Water Heat pump for all new furnaces
5. $1000 = Natural Gas Runs Out ‘ala California (& it almost happened in April 2003)
— Salt Mine Storage (75% usable, “real” working gas is now 33% of Storage bassed on 2003)
— we can increase margin 30% & actually have Leftovers to SELL.
6. $800 Billion = LIFESPAN DECREASE
— EXPLORATION (in 100 years of statistics , LIFE jumps, 8 years AFTER) (in effect: NEED MORE NASA)
7. $700 B. Traffic Accidents (ca $30 Billion of this is paid by Transit-users)
— Electric Roads will allow an “Interlligent road” — while recharging batteries as we drive. PS this is 1990’s updated = 300 damage to people & 400 to car; 2004 NS(?Rumsfeldites) say “only” 241 (with 41 (!) damage to cars? — what are they smoking?).
8. $600 Billion = Climate Change with 300 mph WIND (NB Ocean Current Turnover
9. $400-600+ Natural Gas SUPPLY Shortage> Note: chance is times 100% as is here NOW
— Solution: TANKERS to Alaska for non-Prudhoe Gas.
— PS: includes GASOLINE increases from difficulty refining without Natural Gas.
10.. $400 Billion: Social Security Shortfall
— Solution: high GROWTH PER PERSON via RESEARCH $.
11. $330 Billion = OIL SPIKE: of $35 Dollars (ie $22 + 35)
— Solution: Platinum, Loan Guarantees (eg for Gas TANKERS), Squirt Gas [CH4] into Coal Plants)
12-16: $100-300 B each: DRUGS, CRIME, ALCOHOL, POLLUTION, ASTEROIDS:
? = 1000 for five
Respectively: Solutions: Foot Police & Coast Guard/same/ALCOHOL: wish I had a clue/PLATINUM from Asteroids & Gas Squirting into Coal Plants, as in #11 /a NASA search for 70m Beta Taurids
17. $82 B. = Peak Oil — as this is 30 years in Future, reduced 50% per Decade for “Present Value” … BUT likely the “Flex Point” where production, while NOT declining, STARTS to level out (as happened to Canadian Gas in about 2000), will hurt nearly as much & I believe the DOOMSAYERS” earlier dates may well apply to it coming earlier for the “LIGHTER” CRUDES … we may already have started to hit that.
Solution (for the situation circa 2050) = Electric Roads, with Electricity from SPACE COLONIES (“O’Niel Program”)
18. $44 = Terror: if a WTC = $220 B, every 5 years
— sending War to Iraq is working — sort of. Problem is that cure is 20 times the cost of the Disease.
19. $27 = Canary Island Landslide
… asphault curtain as below Dams, & may delay UNTIL water table starts to shift to wet the crucial slope.
20. $17 Billion/year = Volcanos
20. ~ Hurricanes: mostly = New Orleans floods: 3 years of past 45 had >20′ surge x $200+B.
Cost to stop: Barrier Islands $3B in 1 year [ PS: SEE HOW JINDAL SNUCK THAT INTO THE BP RESPONSE ]
+ Army outer Wall 15′-25′-40’ = $6-13-25B + anti-overtop =$ 2+B
Total = 3+6+2 = $11 B.
[ less than Current Plan to heighten Inner Wall from 14 to 16 feet. And a Bonus: it would work ]
