Permafrost / Re: Toward Improved Discussions of Methane & Climate

Graphene is a wonder material, and turns out edges control whether semi or full conductors. Likewise, adding strain, by twisting ribbons, allows you to attach conducting leads.

In ASTRO-geo, it's been found that 10% off all IDP's are nano diamond, and most stony meteorites appear to have same. And in those same dust particles, they have watched graphite re-shuttle molecules across their own structure to rebuild damaged portions, that they disrupted in experiments. They think that the graphite is also converted to diamond from cosmic ray hits.

2d surfaces, and carbon in particular, are pretty amazing.

These "strange metals" clathrates, really are going to be interesting to crustal geology too. If these materials can push phonons along on the 2D surface, it could change some basic theory of seismic signals, heat transfer, and even planetary magnetism.

Seems like the "filler" materials in the "cages" could also be usefull for tracking blobs and plumes across boundries too. Signatures of volcanic emissions may be better grouped than the micro glass structures they are using now too.

who knew clathrates were going to end up being classed as "strange metals"?

Gonna be interesting how it works out....

A "diamond" cage of carbon and boron create a new type of clathrate.

"The result is a 3D, carbon-based framework with diamond-like bonding that is recoverable to ambient conditions. But unlike diamond, the strontium atoms trapped in the cages make the material metallic—meaning it conducts electricity—with potential for superconductivity at notably high temperature.

What’s more, the properties of the clathrate can change depending on the types of guest atoms within the cages.

“The trapped guest atoms interact strongly with the host cages,” Strobel remarked. “Depending on the specific guest atoms present, the clathrate can be tuned from a semiconductor to a superconductor, all while maintaining robust, diamond-like bonds. Given the large number of possible substitutions, we envision an entirely new class of carbon-based materials with highly tunable properties.”

Alaska is having a hell of a time growing sea ice

""It has been a remarkable freeze-season (or lack of) so far," noted Zack Labe, a climate scientist and PhD candidate at the University of California, Irvine. "Overall, the last month has featured large areas of open water north of Alaska and Siberia."

Facing Extinction
by Catherine Ingram

Because the subject is so tragic and because it can scare or anger people, this is not an essay I ever wanted to write; it is one I would have wanted to read along the way.  But the words on these pages are meant only for those who are ready for them. I offer no hope or solutions for our continuation, only companionship and empathy to you, the reader, who either knows or suspects that there is no hope or solution to be found. What we now need to find is courage.

Dust from a giant asteroid crash caused an ancient ice age

“Our hypothesis is that the large amounts of extraterrestrial dust over a timeframe of at least two million years played an important role in changing the climate on Earth, contributing to cooling,” says Heck.

“Our results show for the first time that such dust, at times, has cooled Earth dramatically,”

x-post from geoengineering thread.

It seems this could explain some of the hydroxyl reduction, and methane concentration spikes. If more open water, then more waves. More waves, more spray. More spray, more hydroxyl reduction from the below H2o2 reaction.

"tests confirmed that water microdroplets spontaneously form hydrogen peroxide, that smaller microdroplets produced higher concentrations of the molecule, and that hydrogen peroxide was not lost when the microdroplets recombined into bulk water.

The researchers ruled out a number of possible explanations before arriving at what they argue is the most likely explanation for hydrogen peroxide's presence. They suggest that a strong electric field near the surface of water microdroplets in air triggers hydroxyl molecules to bind into hydrogen peroxide."

a blog post by one of the authors of the above mentioned "West Antarctic ice loss influenced by internal climate variability and anthropogenic forcing"

"What Figure 1 suggests is that the winds in this region have varied between easterly and westerly from decade to decade, throughout the 20th century. This is the natural variability associated with ENSO, and is no surprise. But in addition, there is a long-term trend. When averaged over several decades, the winds can be seen to have shifted from mean easterly in the 1920s through 1980s, to mean westerly thereafter.

The trend in the winds is small, and easily lost within the variability of individual model ensemble members, but it is robust (it occurs in all the ensemble members) and statistically significant. Moreover, we know its cause (at least in the model experiments): radiative forcing. Although these experiments also include radiative forcing changes resulting from the ozone hole, it’s clear that the trend in the winds begins well before ozone depletion begins in 1970s. Thus, the key forcing is greenhouse gases."

Hadn't seen this one- reducing the number of trees in Siberia, to increase its albedo ?

"The core idea is delightfully counterintuitive: Siberia has too many trees. In ages past, Siberia used to be grassland, and today it is mostly forest. Although trees can sequester carbon in their trunks and branches (at least until they burn or decompose), Siberian forests have significant drawbacks with respect to climate change.

First, forests don’t reflect a lot of solar radiation. A treeless, grassy Siberia would increase Earth’s albedo, reflecting more solar energy back into space. Forests absorb more solar radiation and put it into the ground as heat.

Second, forests are poor habitats for snow-trampling herd animals. In the winter, a thick layer of snow acts as an insulator on the permafrost, preventing frigid above-ground temperatures from reaching deep into the Earth’s crust, where they can shore up the frozenness of the permafrost. When large herds of grazing animals trample the snow, its insulating properties are reduced and the permafrost can hard freeze. Forests reduce these snow-trampling grazing populations."

The Methane Detectives: On the Trail of a Global Warming Mystery

"Scientists continue to offer competing hypotheses to explain the global uptick, and there is no shortage of potential suspects.

Only three elements of the global methane budget are large enough to be plausible culprits: microbial emissions (from livestock, agriculture, and wetlands); fossil fuel emissions; and the chemical process by which methane is scrubbed from the atmosphere."

At a glance summary of how the cash payment limit will work 176.33 KB

In the 2018-19 Budget, the Government announced it would introduce an economy-wide cash payment limit of $10,000 for payments made or accepted by businesses for goods and services. Transactions equal to, or in excess of this amount would need to be made using the electronic payment system or by cheque. The Black Economy Taskforce recommended this action to tackle tax evasion and other criminal activities."

It could be that the RRR, the ridicoulously resilent ridge, is not outgassing as much methane right now, and that is not giving the polar streams the push out and down they have been getting the last 3-4 years.
Maybe related to the arctic warmth, and permafrost melt allowing more mud to flow down rivers, and rebury ocean shelf permafrost and methane hydrates?,2185.0.html

There is also supposed to be one of these off the coast of Greenland, tho i don't see it referenced elsewhere.

Holocene warming effect of southern ocean

"Because of the enhanced Southern Ocean upwelling, the biological pump weakened over the Holocene, allowing more carbon dioxide to leak from the deep ocean into the atmosphere and thus possibly explaining the 20 ppm rise in atmospheric carbon dioxide.

“This process is allowing some of that deeply stored carbon dioxide to invade back to the atmosphere,” said Sigman. “We’re essentially punching holes in the membrane of the biological pump.”
