Melt  

Well, this is disquieting.

Bonus oddness: the record-high amount of Antarctic sea ice, even as the surrounding and supporting Southern Ocean warms. Although the published interview on that subject doesn’t really provide a hypothesis for this effect, I’m willing to toss one out: melted continental fresh water is flowing into the ocean, perhaps enough to slightly reduce the salinity of the surrounding sea. This would raise the freezing point of the affected water, resulting in more solid chunks of water floating around.

Experiment: collect samples of liquid and frozen water from various points around the Southern Ocean and the continent. Compare with historical salinity levels, if available; otherwise, find a reasonable, measurable proxy for historical oceanic and continental salinity levels.

(Originally pounded out for my tumblr page. Yes, I have one of those wankfest things now. I have a good reason, though: the iOS client features larger, easier-to-read font than the Livejournal client.)

((No, I haven't posted in a while. At first, for many months, I simply felt unable to express lengthy ideas, or that whatever ideas I was producing were incomplete, inaccurate, unclear, unoriginal, not useful. Then. I was busy dealing with disasters. I'm OK now, and feel like pounding out some longer thoughts again. Fuck it; the first draft doesn't need to be perfect, not everything needs multiple editing passes, and I can post corrections later if a fact is incorrect or analysis is faulty.))

(((This has three parentheses, just because I can, dammit.)))

Related to that, recent data shows that the bulk of the carbon release associated with the paleocene-eocene thermal maximum (PETM) occurred in just 13 years.

Imagine all the pent-up carbon in permafrost suddenly being chewed on by methanogens year-round, or simply freed from clathrates.

It would never make you heretic
Just for a few words parenthetic
But I'd love it if you
Would dig and rescue
My wrongly-spammed words pertinentic.

(Okay, so that's not a word.  I don't care.)

It's a word now, and a perfectly cromulent one at that.

(I wondered why comments were disappearing. Shows how often I actually check service updates; I had no idea automagic anti-spam had been implemented.)

(The greater crime is that it didn't rhyme, but don't tell anyone.)
