Arctic summer ice cover is 31st highest ever recorded
It's that time of year when the sea ice in the Arctic shrinks to its annual minimum, and it appears that this year's figure is most probably in. It's the 31st largest minimum extent on record, as it happens, which isn't especially newsworthy as reliable records only go back 35 years. It's a lot more fashionable to report this …

Re: This again?
"he gets a little credit for that"
Lewis is OK in my book. (Though I prefer his earlier fuinnier stuff about military contracts and bombs and shit)
For those that want it, these articles always provide food for thought, and over-the-top opinions for those that don't. Lewis is a professional journo who is well aware that his audience are, for the most part, reasonably intelligent people who are capable of forming their own opinions, yet he's writing about a polarising subject where common sense all too often takes a back seat.
It's impossible to approach this subject without some personal bias - same as with religion. And the fact that Lewis does so with such a heavy bias tells me that he's simply playing to the audience. Sure, he believes what he's saying (the personal bias), but it's the way that he's saying it that I always take to be a bit of an in-joke. And one that we are all in on.
Except some people obviously aren't.

Yes there is. There's this thing called "science" which was invented to minimise personal bias and stop humans believing in stupid shit that causes harm to themselves and others.
Lewis can believe whatever he likes. Anyone who knows the fact also knows he's talking bollocks and playing the selective quoting game - which is fine, if you like that kind of thing, and think species extinction is a bit of a larf, innit.
What less fine is an online pub like The Reg - which is supposed to be about tech - aggressively pushing indefensible kooky crank positions as if they're just as informed and useful as something by (say) Trevor Pott, who actually does know what he's talking about.
And that's not just because it's wrong - it's because it's an opportunity missed to go all the way and run anti-vaccination and lizard people conspiracy pieces as well.

Re: This again?
Then stop whining and post up the evidence you have. Are you saying that the passages were not open 70 years ago or that they were but for some reason other then anthropogenic reasons? Are you saying that the Antarctic is not gaining ice at the moment or that it, again, it is but for another reason? Are you stating the AMO is not changing? Are you stating the much anticipated increase in global temperatures predicted by the likes of Michael Mann at the beginning of the century did occur despite the observed hiatus?
Personally, I feel there may be an anthropogenic component to long term climate change but on a system as massive and complex as the atmosphere and oceans on Earth which change over generations, surely only a fool would be on only one side of the argument while so little significant data is in.

To counter the authors lack of any sense on this matter the simple fact that the data indicates the 4th lowest figure is in no way insignificant.
It depends entirely on the data itself, for all I know the 3 worse figures were all only marginally worse, all in the last 5 years, and all way off the far side of the graph.
To say it's insignificant for the reasons he is using is somewhere between stupidly lazy and f*cking dishonest.

Lewis doesn't need to post all the articles in the other direction, because most everyone else is busy posting them. No point in spending time writing the same stories everyone else does.
You can argue that's wrong, that he's biased, and so forth, but either you think he's doing it because he's chasing clicks (in which case you fell into his trap) or he's trying to brainwash people into believing like he does (in which case you're wasting your time reading this article, because you're already brainwashed in the other direction)
He may go off the deep end with some of his stuff, but it is hard to argue that the idea that headlines like "4th lowest ice extent ever" that don't point out the records in this case go back a mere 35 years, is as much propaganda in the pro-AGW direction as his articles are in the anti.'
And that's the problem, both sides are trying to sell their goods and conveniently leave out the "inconvenient truths" that don't point in their direction. Does Lewis leave out a lot of stuff in his articles that don't support his position? Damn straight, but if you think that's not true for articles that support the opposite position, you're brainwashed rather than thinking critically.
I used to be a pretty strong believer in the pro-AGW side until I learned more about how severely the temperature records are adjusted - and always mysteriously down in the past and up more recently. That really disturbs me, and if you are willing to overlook or dismiss that you are as close minded as those who think it is all a hoax by people who can make a buck off 'green' technologies. I badly would like to see results that are COMPLETELY unadjusted to see what they look like but they do not exist - in fact adjustments are being done on previously adjusted data which only makes the problem worse.

No we won't
There is zero chance of ending up like Venus (well until we are both engulfed by the Sun as it Red-giants as the hydrogen is depleted). The Earth is a water planet - the water exists in all three states. That buffers the temperature of the Earth - total energy with the Earth's system can only be determined when you know the ratio of vapour to liquid to solid H2O. This will adapt if there is more energy or less energy (until ice ball earth) keeping the temperature fairly stable.
CO2 can only theoretically have an effect where there isn't any H2O - (especially with the overlap in IR absorption spectra)

It may well be that Earth has a limited range of climate, but living at either extreme of that range is likely to be uncomfortable.

Venus
The whole Venus thing is interesting. It's a nice first-year physics problem to produce entirely naive estimates of what the surface temperatures of the (non-gas-giant) planets should be, just assuming that they are black bodies, and knowing the distance from the Sun, and either working out based on the solar constant or looking up the power output of the Sun.
The answers are pretty good: you get about 278K for Earth (5.5C) which is right within a surprisingly good margin. And you can do the other non-gas-giant planets and they're OK as well (within a few percent, which is amazing considering how naive the estimation is).
Except Venus, where you predict 328K (55C) but the actual temperature is 735K: more than twice as high (Venus is hotter than Mercury).
Well, clearly whatever is doing that has nothing to do with water, since there's no significant water on the other planets either. So it must be something else.
(I'm not suggesting Earth will end up like Venus!)

And do you demand the same openness in other sources of models and data with much bigger expenditures and less openness (OBR and OECD 'forecasts' for example). If not why not? You know you can get at all the climate data, and no one is stopping you running/developing/copying the climate model codes?

Well, of course the actual data is available, as are the sources to the models and their configurations. Often they are not quite open source – UM (the Met Office model) for instance is used for NWP as well and so is not completely open source. But anyone who is interested can sign whatever license agreement is involved (which won't involve money) and can then look at it and review the code, and I'm sure they would be very happy for people to do that.

Yes, CO2 is part of the life cycle of the planet. However, that doesnt mean it isn't a pollutant. Any substance that occurs in a concentration or form that adversely effects the environment into which it is introduced is a pollutant. CO2 has even been shown to adversely effect photosynthesis in concentrations that could exist atmostpherically.
So, not pejorative really is it? Bigot? Prejudiced? Give me some facts and I'll consider them.

To counter your counter:
Almost all "smallish fishing boats" of the day ( and even quite a few modern ones ) are shallow-draft. This may have a reason, y'know?
And yes.. taking an icebreaker, or in the case of the pre-steam efforts: a heavily reinforced hull, through those passages is simply common sense. "Open" is not the same as "clear sailing" there, and large ( and at speed even some not-so-large..) chunks of floating ice are still good for some decent wear-and-tear on your hull if you're not careful.
And there are luxury liners that do sail into similar waters, actually. A bit of Googling gives you a nice set of choices for the Arctic in summer.

"Amundsen used a smallish fishing boat with a tiny draft,to get through he had to use routes where the water depth was < 1m"
Huh??? colour me confused, but surely a boat with a tiny draft can use any route where water depth is >1m, not <1m. And surely a supertanker with much larger draft has to stay in deeper water and have more limited choice of route.
That phrase would however make sense if you replaced "water depth" by "ice thickness"
-

?? A smaller-draft boat has more route choices, so could avoid the ice. To amplify the point, a kayak is less sensitive to the presence of ice than a tanker.

That is not all
Russia using the _WHOLE_ route to the Pacific Ocean for international trade is news and is not the common use pattern.
Most of their arctic shipping goes as far as Tiksi, because the pattern is - deliver by an icebreaker convoy to a port at the river delta, move the cargo there to/form river barges and ship up/down one of the gigantic rivers that span the tundra to mining and industrial settlements (usually on the river) further south. The last river which is usable for commercial navigation going East is Lena which is frozen long enough in the year to require special river nuclear icebreakers.
The part between Lena and the Chukotka peninsula is generally not in use. On top of that, it is the part where the ice tends to pile up till late summer so you really want a nuclear monster to lead the convoy and most of these are busy providing shipping to/from the big river deltas. So while Russians have had the capability to sail anywhere in the arctic for decades, they have not made use of it for commercial shipping from the far East to Europe.

I was fascinated by a recent article on the 'oic era (I forget which) when the oxygen content was much higher (~30%) allowing the development of giant insects and other diffusion controlled respirators such as arthropods.
Evidently, the fossil record points to massive, MASSIVE, forest fires planet-wide (no surprise really). This would make it pretty 'ot at ground level but nothing to compare with the sun's impact on earth's climate. However, it would have put shedloads of carbon dioxide into the atmosphere.

I can't speak for the particular case you're talking about, but I think there is increasing evidence that a lot of mass-extinction events have been warming-related catastrophes. In particular the Deccan Traps released a really enormous amount of greenhouse gases during their formation and there's at least some evidence that this may have contributed to the K-Pg extinction (ie the extinction of the non-avian dinosours). I think the current notion is that it was a combination between warming because of this and a big meteorite strike.

For that to be a viable explanation, you'd be implying that the first observation(s) were, by chance, higher than average, and that subsequent observations were lower due to being scattered around a mean which is lower than the initial observation(s).
Look at this graph Arctic_September_sea_ice_decline.png [wikipedia/NSIDC] and ask yourself whether (a) the first few observations are outliers with the subsequent observations scattered around a lower mean value, or whether (b) there is a general trend downwards.
If that were a graph of my bank balance then I wouldn't be thinking "ok, so I was unusually well-off in the early '80s but on the whole everything's ticking along nicely" - I'd be thinking I was living above my means, and urgently looking at ways to reduce my outgoings.

Strange conclusions
I see a few problems with this article.
1. The raw arctic and antarctic sea ice data are present here
http://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/
a careful look over the charts shows a clear and highly accurate although not quite precise downwards trend.
The trend for the arctic seems downwards and accelerating, the trend for the antarctic(sea ice) is somewhat upwards and steady.
35 samples is quite sufficient to determine a trend. In biotech we often use as little as 5 samples to determine a trend within a 10% margin of error, although the trends are usually more clear then this.
2. You mentioned the antarctic sea ice extent being larger in current years.
this could be the cause of two things: either there is more ice in the antarctic or more ice from the antarctic mainland is flowing into the ocean (this would mean ice is melting faster and would be an indicator of the antarctic warming, not cooling)
interestingly enough only data about the sea ice around Antarctica is available anywhere. Why isn't anyone measuring the ground ice? Or if they are, why isn't the data public?
3. "And it's the thirty-first highest on record, which isn't that odd as there have only been reliable records for thirty-five years"
What kind of BS is this? This is just like the guy who looses the race but says I wasn't among the last, I was in the top 31,... out of 35.
4. "If the AMO does turn cold, it's at least possible that the arctic ice recovery seen over the last couple of years will continue."
Recovery compared to what? the 2012 anomaly? You don't have to bee a scientist to see that that was a fluke. I see no indication of long term recovery in the data.
I encourage anyone to look at the data and draw their own conclusions. I have a feeling that the person who wrote this didn't bother to do so.

It's politics, not science.
Facts do not matter in politics, except when politics says the passage will be open and people find themselves being rescued by the Coast Guard. Any facts or reality can be rationalised away or ignored when it comes to politics. Too bad we didn't have a discipline that could ignore politics and money and tell us what is....oh I guess that would be religion.

4, 31, 35 hut, hut, hike
I'm not sure which way around the problem is, but if the figures are the 4th lowest on record surely that would make them the 32nd largest in a set of 35 results, not the 31st largest. Alternatively, the 31st largest figure would be the 5th lowest.
From lowest to highest:
HighToLowPosition,comparative,LowToHighPosition
35,lowest,1
34,2nd lowest,2
33,3rd lowest,3
32,4th lowest,4
31,5th lowest,5

Of no real significance?
"Fourth lowest is of no real significance at all"
...unless you're one of the many arctic polar bears who are increasingly being forced to venture into human settlements to compensate for the growing difficulty in being able to get out onto the sea ice to catch seals:
"Polar bears are not aquatic, however, and their only access to the seals is from the surface of the sea ice. Over the past 25 years, the summer sea ice melt period has lengthened, and summer sea ice cover has declined by over half a million square miles"
