Irreversible Warming Tipping Point May Have Been Triggered: Arctic Mission Chief

The tipping point for irreversible global warming may have already been triggered, the scientist who led the biggest expedition to the Arctic warned Tuesday. AFP:

"The disappearance of summer sea ice in the Arctic is one of the first landmines in this minefield, one

No doubt it has already been triggered in my view. but I would hesitate to describe the Arctic Ocean as "dying", changing certainly, possibly in irreversible ways that would lead to a different physio-ecological regime for the region, perhaps one that humans don't like. but nevertheless life will persist there, and some types of life will even flourish there. I have a handful of friends who are sea ice scientists, studying changes in not only the duration of old sea ice but also changes in ocean circulation related to the absence of sea ice. Some of my own research involved how these changes in circulation patterns are affecting biology in the region. it's a fascinating subject area, and one that I wish I was still more involved in.

You are absolutely right. But that tends to be the popular language. Some conservatives seize on that language to insist the same sort of thing, e.g., there can be no, 'end of the world.' It's unfortunate, that most people want to talk somewhat subjective terms. Sometimes that helps things, often it doesn't.

Your research sounds fascinating! Let's hear about it! And you can still be involved, a bit, at this community! You have great credentials. I think I should make you a moderator, yes? Don't worry, there are virtually zero responsibilities. Mainly a subjective sort of thing, you know.

hey now. i never agreed to this moderator thing. but ok fine. seems like maybe you could use the help, given that you are also managing about a gazillion other communities.

i utilized acoustic doppler current profiler backscatter to look at patterns in diel vertical migration of zooplankton as indicators suggestive of changes in bowhead whale migration pathways within the bering-chuckchi-beaufort system, and how this was likely affected by changes in water mass properties and circulation, particularly in the Barrow Canyon area. but my research was never published because i never finished. my advisor did end up publishing portions of it just this past year actually but i was not credited. so maybe not such great credentials afterall.

Well, I haven't counted. I think if I make a certain number of communities I might somehow break through to the other side

[arrctic]

not sure if i should be insulted by paris reading a book or not. i think i preferred the pirate penguins, even if they are anti-arrctic.

you're being a tiny bit redundant but that's ok. i run a community myself so am mostly familiar with the management panel already, but you've provided a good overview which is very kind and helpful. my community started at four plus and has dwindled down to about two crazy people. your descriptions are not inaccurate in my experience.

all the analysis for my research was done in MATLAB, which is a matrix analysis program, derived from Fortran. so yes, lots of math and programming and variables and if/then loops. the primary formula that i had to develop was just to extract and amplify the migration signal from the backscatter. if the signal wasn't strong, this could be challenging.

professors who steal from students are no good. i wish there was a way of identifying them from afar so that i could stay a-far far way away from them.
