I'm serious. I understand that climate change has terrifying consequences and it bears on my mind and life decisions every day. It's the most important thing that will happen globally in my lifetime and I get uneasy thinking about how the world will be when I'm old and possibly with grandkids. I mean, I can't even fathom the loss of life and destruction CC will bring to 3rd world countries. Millions dead in a modern holocaust (I'm not being hyperbolic)? But at the same time, I realize most people don't have the time to research and get stubborn and get caught up in old ways of thinking, and getting in petty angry arguments with people or doing judgmental ad-hominem attacks won't do jack poo poo.

LookingGodIntheEye posted:I hold nothing against him on it, I was just interested to know if there's any validity to his arguments, especially the volcanism in the arctic one. I rather doubt it. It's all divergent plate boundaries up there, which don't cause volcanic activity. The reason we have volcanoes in a big circle around the Pacific is because the Pacific plate boundaries are mostly convergent. You might try the "oh yeah, then why are our oceans turning to acid?" route.

Bizarro Watt posted:That's a new one to me. Typically when people mention volcanic activity re: climate change, it's in the context of CO2 emissions (in my experience, but that's from a more paleo perspective). Geothermal activity in the Arctic isn't anything new though, I mean Iceland uses it for power because it's right on the mid-ocean ridge. Unrelated question: how does the heating of the oceans affect sea life, especially as the deep ocean absorbs much of the recent warming? Warmer oceans should lower O2 content.

Tell him, 'like the President / the American President (depending on the location), I'm not a climate scientist, hence in such complex matters involving (buzzwords such as 'nonlinear dynamics' , 'systems of such high complexity and scale', 'chaos', 'highly dangerous regime/ paradigm shifts/ tipping points') *and* expert knowledge from the climate science field, I prefer not to rely on single indicators, but defer to the well-established scientific consensus based on aggregates developed over decades of peer-reviewed work and the experience behind that work. It is my belief that this consensus has been made clear enough, and that it is high time to move on to resolving this problem.' Basically, humble yourself, do an ad auctoritatem, don't engage, pay attention to the complexity of the problem and change the terms of the conversation, unsubtly indicating that guy is trolling. Better first make sure you pass, though.

pangstrom posted:This is the part that's weird. He's a statistics professor and those arguments aren't really the stuff of "don't have the time to do research". I mean maybe it's Croatia's (or wherever's) version of low information denialism but matching variances and increments and pretending there is a supremum problem doesn't really sound like it. It smacks of a pretty focused effort to dissemble by people who should know better. So either he's doing it or he paid attention to somebody else who did. I was definitely assuming whatever bpower was about him, it's an assumption that's going to be right 99+% of the time. It's not about whether he's a "bad person", not sure why you keep going there, it's that unless this is a homework question in disguise or something it's a fundamentally dishonest argument about climate change. In my experience, the climate skeptics I've seen are typically people that are politically casual and get all their news from tv or other crap like that and have a poor understanding of world events. People that, if you gave the right information, would probably change their minds. But I've been raised in relatively liberal Southern California (away from the more wealthy, conservative OC types) my whole life so I haven't come across a lot of dedicated right-wingers, usually at worst middle-of-the-road.

LookingGodIntheEye posted:Unrelated question: how does the heating of the oceans affect sea life, especially as the deep ocean absorbs much of the recent warming? Warmer oceans should lower O2 content. Yes, it affects sea life in big ways. Warmer water allows for a higher concentration of dissolved CO2, which shifts the oceans chemistry to a higher acidity, hindering the formation of calcium carbonate shells in sea life. This has ramifications for the entire ocean food web. link link

Elotana posted:There was a skeptic meme a few months back where they took a paper that noted volcanic activity under, like, one glacier in the Antarctic, and it got megaphoned into "VOLCANOES, NOT GLOBAL WARMING, CAUSING ANTARCTIC COLLAPSE." The actual scientist responded to a blog's inquiry by gamely replying that the effect they noted was several orders of magnitude smaller and more localized than temperature change, but skeptics had moved onto another SQUIRREL by then. The reason they don't push back and raise a huge stink over their work being taken out of context by skeptics and write up responses etc is primarily because they're too busy being scientists. Additionally I assume that most research facilities have general unwritten/unofficial policies that read something like "keep your head the hell down, we have enough poo poo on the plate to deal with without getting targeted by any of these skeptic organizations." Any time I do contact a researcher directly, I go out of my way to emphasize that I do not own a blog, am not a member of the media, and am not a member of any organization that has anything to do with energy or the environment. Also I make sure that my question is as succinct and specific as possible, even a T/F if I can. Pretty sure I get more responses by removing any possibility of distortion/gotcha bullshit?

This is really my problem, I accept the scientific consensus about climate change but I can't really accept the conclusions, or at least I can't think about them too much. Otherwise things in life seem unbearably futile. And I really don't have time for that kind of thinking. Best thing to do I figure is write letter to politicians about the issue and vote for more environmentalist candidates who actually have a chance of winning. Aside from that, not sure how activist I can or should be.

Trabisnikof posted:Yes? But that doesn't mean the scientific consensus is that if we follow business as usual the apocalypse will happen either. If you're talking about the likes of Richard Tol, Nordhaus and other climate economists fond of their welfare optimisation models, these are full of nifty tricks that smooth out impacts to make a 'clean' cost-benefit analysis (high discount rates, utility functions and Negishi welfare weights). Neoclassical economics has trouble with non-marginal problems and in my view has very little to say about the seriousness of climate change.

Something like 5-10k years at least.

I was under the impression that while we've been aware of methane release from the ocean floor (I think this was a big scientific explanation for the Bermuda triangle a ways back), we had no way of accurately measuring it over an area that is mostly empty. Only recently have scientists been going up there to test it.

How much of it is going to be released by the end of the century nobody knows, but personally I'm loving terrified about the implications it could have.

I'm not a climate scientist or a paleontologist, but my understanding is that methane clathrate release is heavily implicated in the Permian-Triassic extinction event (the one largest in history), as are anoxic bacteria. Granted, it was a massive event and it's pretty much impossible to establish direct causalities, but a quick google scholar search turns up clathrate amounts measured in tens of thousands of gigatons in the ocean floor and hundreds of gigatons in permafrost, though much of it is not under threat from currently predicted amounts of warming. How much of it is, and if that will be enough to set off a runaway chain-reaction, I haven't got a clue. The scary thing is though that once it goes off, there's absolutely nothing we can do about it. It would mean the end of our species. lollontee fucked around with this message at 18:05 on Jan 30, 2015 |

Because those clathrates go, we'd be talking about warming beyond 6 degrees celsius and anything up to 12 or even beyond that. That would guarantee an ocean system so acidified and oxygen deprived that anaerobic life begins to take over. And once that happens, everything dies.
