Consequences / Oceanic anoxia
« on: January 04, 2018, 10:27:25 PM »
Perhaps the most terrifying aspect of the climate crisis is the trend towards oceanic anoxia, discussed here...

It seems to me entirely probable that, if the oceans tip into an anoxic state, the atmosphere will necessarily follow.

I presume its also possible that, like a stagnant pond, the oceans could begin producing noxious gases such as hydrogen sulphide, nitrous oxide, etc, instead of oxygen. I vaguely recall an estimate that around 70% of the oxygen produced within the carbon cycle is the product of oceanic plankton...

As the article above concludes, "If you can't breathe, nothing else matters."

This has been mentioned in passing occasionallly on here, but I couldn't find a thread...

Policy and solutions / IPCC WGIII Report

This report focuses on mitigation. It is trailed here...

More to follow, when the actual text is available.

Arctic sea ice / NSIDC Monthly Reports and matters arising
« on: March 08, 2014, 08:11:40 PM »
The NSIDC Report for February 2014 has been released...

I thunk these regular reports, which once we used to chew over at some length, probably deserved a dedicated thread...

Science / WACCY Science
« on: February 17, 2014, 04:16:40 AM »
WACCY stands for Warm Arctic Cold Continents - the predicition being that, as the Arctic warms, this will cause cooling of North America and Eurasia.

Given this winter's weather so far, this paper from Cohen et al is looking topical and smart...


Arctic sea ice was observed to be at a new record minimum in September 2012. Following this summer minimum, northern Eurasia and much of North America experienced severe winter weather during the winter of 2012/2013. A statistical model that used Eurasian snow cover as its main predictor successfully forecast the observed cold winter temperatures. We propose that the large melting of Arctic sea ice may be related to the rapid advance of snow cover, similar to the connection made in studies of past climates between low Arctic sea ice and enhanced continental snowfalls and glacial inception via ice sheet growth. Regressions between autumnal sea ice extent and Eurasian snow cover extent and Northern Hemisphere temperatures yield the characteristic "warm Arctic/cold continents" pattern. This pattern was observed during winter 2012/2013, and it is common among years with observed low autumn sea ice, rapid autumn snow cover advance, and a negative winter Arctic Oscillation. Dynamical models fail to capture this pattern, instead showing maximum warming over the Arctic Ocean and widespread winter warming over the adjacent continents. We suggest that the simulated widespread warming may be due to incorrect sea ice-atmosphere coupling, including an incorrect triggering of positive feedback between low sea ice and atmospheric convection, resulting in significant model errors that are evident in seasonal predictions and that potentially impact future climate change projections.

I have a hunch that earlier papers from Cohen may be a better place to start this topic. See/share below...

Walking the walk / Transition network
« on: November 02, 2013, 12:27:26 PM »
Not strictly INDIVIDUAL, as per the criteria for this section, but then that's the point; I thought that some people here may not have come across the Transition Network,

This aims to help communities transition to a lower-carbon future, by taking practical steps in the present. It seems to me that this focus on COMMUNITY efforts is potentially much more effective.

Anyway, I don't speak for the Transition Network. that would be Rob Hopkins, interviewed here;

They have a website here:

Science / Wyatt (and Curry's) stadium wave paper
« on: October 12, 2013, 12:30:15 PM »
This seems to have generated enough comment on the latest blog thread, here... suggest that it may be worth a forum thread.

Read more at:

The full paper is linked at Curry's website...

...where those of you prepared to scroll past a lot of squabbling between the inmates of the comments section will find some interesting elucidation fron Wyatt, to whom I think the main credit for it accrues. She's been working on it for 7 years, JC for 6 months or so.

"I fear the Greeks, even bearing gifts," but even so I think this is a very interesting paper; it posits that the AMO drives an ebb and flow of the ice edge in the Kara, Laptev and East Siberian seas. This, in turn, triggers changes throughout the Northern Hemisphere.

As Dr Jennifer Francis has commented, about the same phenomenon, in another context "How could it not?"

It does seem to relate quite well to the specialist interests of us ice junkies, so fire away...

The rest / Arctic/AGW humour and satire
« on: October 11, 2013, 04:04:39 PM »
Hi all,

One of the big growth areas in the internet I've seen since my return from my sabbatical seems to be a big growth in the number of satirical reviews of anti-science sites.

I see this as a very positive development, and one which may prove as important in the "Climate Wars" as the still excellent, very important, but often rather dry material provided by sites such as "Open Mind" and "Skeptical Science".

The new, to me, "Hot Whopper" site is even prepared to trawl the comments sections of WUWT for unintentional humour - a thankless task, for which I cannot thank them enough, as it means I don't have to.

And they have a lot of excellent links on the side bar, to this sort of thing:

I thought other regulars on here might enjoy some of this light relief from more serious stuff, and please do share any more good bits.

Finally, you've probably all seen it, and its not updating, but the first post in this thread would be a travesty if it didn't contain a link to the granddaddy:

Enjoy! (and if you do, please return to share)
