His site is down -

He hasn't used twitter since March 16.

Does anyone have any information as to his well being?

All thanks in advance.

It is unclear how disastrous that would be. There is certainly chances of large amounts of methane and CO2 being released but there are also chances that such emissions won't increase all that dramatically for quite a while. .

Serious question - what is to prevent large amounts of methane being released? And how long is quite a while?

Neven, thank you again for this forum.  I'm continually surprised and delighted to be able to stay informed by the thoughtful commentary and expert opinions of the members. And recently I've been humored by the expert handling of trolls.   ;)

The Black Mat

Something happened ~ 12,900 BP in North America that caused the collapse of a huge number of species. One of the attempts to explain this die off is the Black Mat theory proposed by Firestone (& Goodyear, believe it or not).

The die-off was massive including everything from mammoths and mastodons, a number of horse and camel species, dire wolves, saber toothed cats and giant beaver. For years man was thought to be responsible for this extinction, but, when one recalls the unsuccessful extermination of modern wolves by hunters in helicopters, the difficulty of capturing, let alone killing wild horses and the resistance that a sabertoothed lion would present to anyone armed only with a thrusting spear, the problems multiply.


Terry - fascinating theory!  Thanks so much for the info and the link.

Is it just me or does this year look much worse compared to 2012?
Something's broken in their model this year and they're trying to find out what. See the following thread for details. I'll keep you posted here if they reply to me again.,1320.0.html

Thanks Peter - looking forward to an explanation.

Consequences / AER Forecast Temperature Anomaly
« on: November 24, 2014, 10:52:26 PM »
Researchers at AER and MIT are taking winter weather forecasting beyond El Nino by investigating the relationship between Siberian snow cover in fall months, and Northern Hemisphere climate variability during the winter. A forecast model developed by AER scientist Judah Cohen has achieved on-target forecasts for major cities in the industrialized countries.

Washington D.C. APR 25, 2013 – The Subcommittee on Environment...

Sadly, the chair of the Subcommittee on Environment is Rep. Chris Stewart (R-Utah).  The Washington Post blog did some fact checking about a recent opinion piece of his and posted this -

"Cherry-picking one survey to discredit a survey of scientists on climate change"

Just wanted to say thank you for starting this tread and that I was happy to find where I could contribute.

I am so thankful for this place where I can learn and ask questions and get answers from very knowledgeable people. I've been amazed again and again by the generosity of those willing to share their expertise and opinion.

Arctic sea ice / Re: North Pole Web Cam 2013

wayne over at the ASI Blog posted this -   


I like the last daily average graph displaying a maxima shift linked with the effect of the sun, the thinner the ice the earlier the maxima. This matches exactly what I have observed. For 2013 at 75 North 95 W the under-ice is melting for close to 12 hours daily. Will post the first 12 hour underside net melting, it could have been yesterday, but I await several days of repetition.

I also remade my calculations about the North Pole cam horizon drop which appears to be very large. I scratched my original calculation and await more pictures. The drop appears beyond all previous observations, this requires more evidence , but may be indeed linked with the recent ridging, suggesting a lot of thin ice about."  (

And the link to his blog is even more interesting - 

Is it just me or are his recent findings very concerning?

Thanks for the link. Well done film! The deniers should be forced to watch like in clockwork orange.


My pleasure Vergent.  I agree it was well done.  Let's hope it's seen by many.

Donna and Abrupt SLR,

Dr Yurganov is aware of what I am posting. We have had a brief discussion of the observations.

I'll add more over the weekend, work has been crazy and I am behind on posting. I'll keep you apprised and may add a couple of Google Earth images with an Antarctic perspective to give us a better way of viewing the concentrations.


Wow! This is fantastic. Thank you so much A4R!  Really looking forward to your posts when you have time.

While helpful, it does not address all of the issues of this winter's ice behavior.


From the video "...where we might see virtually ice free summers in the arctic in just a few decades." 

I wish I were that optimistic.

Antarctica / Re: Antarctic Methane Concentrations

The April atmospheric methane concentrations in portions of the Antarctic look higher than those currently in the Arctic, per this link:

Indeed they do. If the highs listed are from there then they are higher than the alarming levels in Svalbard in January.  I wish this site -  were up to date. 

I wonder if this has caught the attention of Dr. Leonid Yurganov, though I know his work in the past has been in the arctic.  If you learn of a site with more exact levels or more information please share.

For those who have not visited A4R's website recently, he has posted methane concentrations including for Antarctica thru March 31, 2013 at the following site:

Looking at the pattern of methane atmospheric concentration around the Antarctic it appears to me that it is occurring in an area where the warm Circumpolar Deep Water, CDW, has recently migrated southward where it may have encountered (and thermally destabilized) ocean sediment containing methane hydrates.

AbruptSLR - A4R wrote the following on the Arctic Methane Release thread -   

I have started posting the METOP2 IASI CH4 for April to June 2013  on a new website due to space constraints.


Sorry but I don't know how to link to a particular comment  :-\

Antarctica / Re: THC origins in the Antarctic side faltering?
« on: April 14, 2013, 05:36:44 AM »
In this regard, I would prefer to use the word "slowing" instead of "faltering" as I do not believe that the THC will "stop" now, or in the future.  Thus, while I agree that the reduction in AABW production will slow the THC (which will induce numerous and complex changes worldwide); I believe these changes will be much slower to unfold than will the impacts of the increasingly warm CDW on the Antarctic ice sheets (most significantly on the WAIS).

Many thanks AbruptSLR, your opinion is greatly appreciated.

Not sure if this is what you're looking for but there are a number of papers referenced that may be of help. 

The Future of Arctic Sea Ice

Best of luck with your project - I hope you'll share when it's finished.

It looks like the new site has different permissions - will you change them to be the same as the old site? 

Also,  at this time I'd like to thank you for all of your work on this. I've followed your posts for quite some time and deeply appreciate access to this information.

Arctic sea ice / Re: "Smart" and "Stupid" Questions - Feel Free To Ask
« on: March 21, 2013, 03:45:54 PM »
My stupid question - what is the "goats head"?  In another thread someone asked if the goats head was going to go into the Fram Straight this year. 

My guess is that it's a persistent multi-year ice formation - is that correct? 

Second stupid question, what are the ramifications of the goats head going into the Fram Straight?
