Ice cap disappearing 30 years ahead of schedule

Both
But the joke's not funny.

You're the one with a spycam Cwispin.

You're the one with a spycam Cwispin.

If you're just here to take the piss, don't ever post again in this forum or on this topic.

 

[ernestolynch]

What?

 

[rorymac]

Watch yer step lynchy .. man is destroying the sky with ozone and it aint funny when you see all the graphs and the histograms. I flung my missus femfresh away last night .. it doesn't smell anything like a fanny imo !

 

[ernestolynch]

Lol

 

[MikeMcc]

Just to be clear; are you some kind of comedy troll in joke that everyone else gets and I havent worked out yet or are you really genuinly as thick pig shit?

Nah, he's just a thick as pig shit troll, with nothing constructive to add to the discussion.

 

[ernestolynch]

Keep the abuse levels down, young Michael, there's a good chap. Don't want your hot air to melt Greenland or something.

He used to be funny, but his material is well out-of-date nowadays.

In honour of the poster who seems to think the USSR was a good idea, an explanation of why a molecule of such small concentrations in the atmosphere can causes so much concernation

Carbonism - the single issue that gets Liberals up in arms.

This is quite a relevant critique on the current view of the absorbtion spectra generated by homonuclear diatomic molecules and there energy gaps that incoming IR can be absorbed by.



Not, your a fucking bullshiter.

 

[Jonti]

It's best just to ignore the clown ~ he was once a noted troll, but he's been left behind as the internet has moved on.

Sad, for him, but true.

 

[ernestolynch]

Lol. 'internet moves on.'

And in other news...

 

[ferrelhadley]

Nail head.

 

[ferrelhadley]

worth keeping an eye on, but those data points are given as being preliminary, rather than verified, so it could be an instrument malfunction or problem with calibration etc.

it is exactly these sort of localised monitoring stations that would first pick up on any major releases from the methane clathrates (sp?) below the ocean, and / or permafrost melting though, so this would be pretty worrying if it was confirmed as being correct.

Response form NOAA on Svalsbard via the Guardian eviroment team....

"We are aware of the apparently contaminated samples from Zeppelin.
It looks like there is a leak in the sampling system and we are trying
to sort it out. I will apply provisional flags to the data that might be affected."

Ah, that feels better.

cheers for posting that up. Still worth keeping a close eye on IMO, as if another sensor also starts showing a big increase it'd seem unlikely that 2 of them would fault at the same time (although I guess if they were all installed at the same time then they could start faulting at the same time as well).

 

[ferrelhadley]

Their analyses indicate that the gradual rise at an average rate of 1 metre per century was interrupted by two periods with rates of rise up to 2.5 metres per century, between 15 and 13 thousand years ago, and between 11 and 9 thousand years ago.

http://www.sciencedaily.com/releases/2010/12/101201120605.htm

So again we find proof that ice sheet responces to orbital forcing can be in the order of 2.5m per century. Orbital forcing is in the order of change of 1w/m^2 per thousand years. Human sourced greenhouse gas forcing will see us at around 3w/m^2 or abover per century.
The kink in the polar jet that has brought icy conditions to the UK has had an impact in other places....

Near-surface air temperatures over the Siberian and Alaskan side of the Arctic were 3 to 5 degrees Celsius (5 to 9 degrees Fahrenheit) warmer than normal in November. Air temperatures over Baffin Bay were also unusually warm (8 degrees Celsius, or 14 degrees Fahrenheit above average). The warm air came from two sources: unfrozen areas of the ocean continued to release heat to the atmosphere; and a circulation pattern brought warm air into the Arctic from the south.

November has second lowest extent on record.

Was at a space conference yesterday where the Cryosat guys went through what they've been doing in terms of characterising the instrument response and so forth. They put up the first data release in one slide, but I don't have a copy yet...

 

[ferrelhadley]

New study suggest that Greenland was in balance during the 70s and 80s but has now gone out of balance and that by 2040 the demise of the entire ice sheet will be pretty much locked in.

It does give a 1000 year life time to fully melt though.

While I am here, if anyone is interested here is a great presentation to this years AGU by Ellen Mosely Thompson, Lonnie Thompsons wife and in her own right a famed glaciologist.

http://www.agu.org/meetings/fm10/lectures/lecture_videos/A42D.shtml

Some interesting stuff with the glacier record, perhaps nothing new to some but a good summary of the science.

 

[ernestolynch]

Good news for the people of Kalalit Nunaat!

 

[ferrelhadley]

The US has pulled about 200 people out of the Antarctic early this year due to the great tragedy in Christchurch, the tradiational base of most Antarctic activity. Due to local conditions apparently even the Globemasters were having trouble getting in to McMurdo sound.

Interesting guest post over at Nevens on the thickness.
We are at just about a record low for this time of year and the sun has returned to the Arctic. Given it was January before Hudson Bay fully froze we may have a rather rapid start to the melt season this year when it gets underway.

Editing to add this on glacial balance, new study from the JPL suggests 15cm from Greenland by 2050.

Hmmm not sure they are accounting for early ice free conditions in the Arctic sea.

 

[ferrelhadley]

Here is another corker of a paper.

Hansen and Sato. They seem to reckon we have exceeded the Holocene optimum over the past decade and are about to induce an albedo flip in the Arctic (no doubt) which will massively extend the meltseason in Greenland. Also the Pine Island Glacier has exceeded a geological restraint on its movement. They make a case that we will be back in Pliestocene climate conditions due to a doubling of preindustrial CO2 levels so that is going to mean 25m sea level rise. Im gueesing the northward progress of the taiga biome will be an important albedo feedback as well though they dont discuss this explicitly.
The paper is a great education in where we are, very worth a read.

Oh dear - Deniers -> shotgun -> foot -> BOOM!

http://climateprogress.org/2011/03/22/climate-science-deniers-berkeley-temperature-study/

Climate Progress is reporting on the preliminary report from BEST - where the chair (a man actually critised for his anti - AGW stance!) is reported to have stated:

•“We are seeing substantial global warming”
•“None of the effects raised by the [skeptics] is going to have anything more than a marginal effect on the amount of global warming.”

When BEST was started it was pretty widely believed that it would be an attack on AGW given that it's climate expert is Judith Curry and Muller's own background. It seems though that the new interpretation of the data is backing up GISS and the CRU.

Story in the Guardian about it today.

Hey hey hey

 

[MikeMcc]

Cheers, that is a pretty damning (rightly so) report, especially coming from the NYT. With the factors starting to stack against any let up in warming but continued observed warming I really think the next 5 years will finally confirm AGW in the populations mind.

People will start to understand what statistical significance really means. When 100 year events start to happen at 10 year intervals they'll start to realise that shifting the bell-curve by a degree or a degree and a half has big consequences. Especially for locations that suffer from amplifying factors, like the Netherlands and ourselves with the North Sea funnel.
