Mt. St. Helens erupted on this day 35 years ago. The area of sea ice on Earth has increased by more than the area of Alaska since May 18, 1980.

I don’t know if you’ve noticed but the above graph does not go back far enough to show the known ice extent for the year 1975. That’s the low ice extent area year ignored by NISDC when determining the ice extent uncertainty often shown on Arctic Ice anomaly graphs.
My job is weather sensative so i do my share on weather research, but i am not a meteorologist or statistician. As i am in agriculture and we develop yield models based on critical weather during the growing season it occured to me that accurate agricultural weather records are critical to accurate yield models and food production. Are agricultural sources of weather data different than the propoganda we hear every GD day?
An example of a source: http://www.fao.org/nr/climpag/pub/en1102_en.asp
and http://www.fao.org/nr/climpag/pub/en1102_en.asp
I dont have the right tools to dig into this. Perhaps one of your team of experts could vet my theory.
Sorry for placing comment in unrelated spot.
(116F in Spain – we are all going to die.)
I am not convinced that humans are the main cause of Earth’s temperature fluctuations. I do have a question regarding sea ice: does the total area of ice correlate to total ice volume?
Not necessarily. Ice that has lasted more than one season is typically thicker.
Yep, ice is a bit like a climate scientist.. The longer it hangs about, the thicker it gets.
Intriguingly if one takes a look at the area of sea ice in the vicinity of baking Alaska one discovers the following:

Yea yea, we all gonna die.
Don’t be silly. The Arctic is ice-free
https://climatedenierdotme.files.wordpress.com/2014/12/b4bw0yiciaapjqb.png
Don’t be silly. Even big Al is quoted as merely saying:
“May be nearly ice-free in summer by as early as 2014″
Which proves what, Jim?
That according to CT there’s a lot less Arctic sea ice this year than in 1980, and that currently at least it’s declining quickly (daily not annually!)
OMG, its coming into SUMMER up there.. idiot !!
It is not declining any quicker than it usually does.

It’s not summer up there yet Andy, but nevertheless:

Small point, but Andy didn’t say it was summer, he said it was ‘coming into summer.’ You tried to score a cheap point and failed.
A bigger point than it may seem, Sophie. We’ve been around the block with him a few times.
Fudging, muddling, evasion and denial.
But of course he was.
I was doing nothing of the sort Sophie. I was simply pointing out that there are already melt ponds in the middle of the Beaufort Sea whilst we are still only in mid May.
And no mater how busy you are intriguing, you can’t find a following.
Poor ;little Jimmy, doesn’t dare use 1972 as a reference point.

Always chooses the coolest period in the last 100 or so years as a reference.
Very “propaganda”
And lets not mention the Antarctic sea ice.
I’m sure there is meant to be the word “GLOBAL” in there somewhere, drone !!
Why not go as far back as 1953 instead, courtesy of the NSIDC?

Why do you simpletons not realise that we are only just climbing out of the COLDEST period of the whole Holocene.
Or do you actually wish to go back into the LIA?
There is plenty of evidence that the 1940’s was probably as warm as now (ignoring Tom Wiggley’s request for “adjustments”)
It was also warmer in the MWP and RWP and most of the rest of the Holocene, but you like to stick to that tiny period of totally beneficially warming from the dip in the 1950-60, because it happens to suit your nappy-wetting screeching
We are, in fact only just above the COLDEST period of the last 10,000 years. Do you idiots really want to go back to that time?
Move to Siberia, fool, and let the rest of us ENJOY the extra warmth while we are lucky enough to have it, instead of having to put up with your incessant whining !!!
Jim, while Baking Alaska and much of the West Coast was slightly warm this year… the vast bulk of Land area in the Arctic and North America was well below normal Temp this past winter…
Thus.. it is completely possible for Baking Alaska to have Less Sea Ice.. whereas overall Sea Ice went back to 1975 Levels…
Also, could we see that Chart to Scale rather than Zoomed in??
Forgive me – I assumed everyone here would already be familiar with:
http://arctic.atmos.uiuc.edu/cryosphere/arctic.sea.ice.interactive.html and
http://arctic.atmos.uiuc.edu/cryosphere/antarctic.sea.ice.interactive.html
I am merely seeking to differentiate between northern and southern hemispheres.
Yeah, we know the Antarctic sea ice is GROWING to new record levels every year.
And the Arctic is starting to rebound from the series of strong solar cycles that caused lower levels for a several years. Those strong solar cycles have now, unfortunately, ended.
What a boon it would be for the Arctic ice to actually decrease.
To open navigation for the world’s trade during at least a small part of the year.
(There are records of this actually happening in the past, but not so much lately)
Russia and other countries with an Arctic shore would be able to use their ports.
We still need some more warming to get out of the grip of the LIA, another degree or so would be so beneficial to most of the world, especially as it would happen in the higher latitudes.
I bet you can find one person in Siberia that doesn’t wish it was a bit warmer. ! (perhaps Jim could move there?)
Unfortunately, that looks like its not going to happen 🙁
The current SLIGHTLY warm period, is coming to an end.
