Clean thread, clean thread, move down!
SJ, what do you make of China cutting a lot more coal projects this week? Grounds for optimism?
As far as optimism about China holding to its promises, certainly.
At least they take things seriously. Hell, even Rick Perry takes climate change and renewables more seriously than Trump. I looked at the details on his hearing. Not great, but not the worst in the world.
You can’t take those statements seriously, especially at confirmation hearings. It’s a rhetorical dodge.
True, but he was a big supporter of wind in Texas
Most stories about climate sensitivity that come to my attention express concern that it’s higher than the current estimate, because I mostly come across such stories on pages that worry a lot about it. So it’s easy to get the impression that, more and more, the evidence is pointing to an ECS higher than 3C. SJ – you have a better idea of the state of science than I do. Is it your sense that the weight of evidence is shifting toward a higher ECS, or am I just being exposed to the more alarming of papers?
A new study has found that 60 percent of primates are nearing extinction
From gorillas to gibbons, about 60 percent of primates, the closest biological relatives to human beings, are threatened by extinction due largely to human activities, a study has found.
Hi SJ, and everyone else. SJ, if you’ve seen this article making the rounds, do you have any thoughts on it?
The comments on the 4th claim here will probably be helpful: http://climatefeedback.org/wall-street-journal-articles-on-2016-heat-record-send-contradicting-messages/
Thanks SJ. I’ m guessing, were it not for the El Nino, thisnyear would have been cooler than the last few. Obviously there’s been a warming trend in the last 100 or so years but the inclination of it’s increase is, I think, not as steep as some would have us believe.
If one lesson has come out of this for me, it’s to be particularly careful with anything the media gets it’s hands on. I knew it already but sometimes I need one more reminder.
I think I’ve said this before, but it’s important not to treat “the media” as a single entity. The Federalist is a highly partisan website, and on climate specifically it’s no better than a random blog. The only thing it has in common with, say, the New York Times is that they both have a website ending in “.com”.
Here’s a decent answer to your question of what 2016 would have looked like without an El Niño: https://twitter.com/ClimateOfGavin/status/821749834877194241
Would this have a significant impact on how much carbon the ocean can uptake?: http://m.pnas.org/content/113/31/8606
Compared to what? Not sure how to answer your question… I mean, the best understanding of ice age CO2 drawdown has been that the Southern Ocean is the biggest player, so this seems to fit with that. I can give you the last paragraph of that paper:
Our findings also have important implications for the global carbon cycle in a warming climate. As the upper ocean warms and stratifies, subtropical biomes dominated by picoplankton that form small, slow-sinking particles are expected to expand. Combined with direct effects of warming on microbial respiration, this might shoal the mean depth of organic particle remineralization and recirculate carbon to the surface mixed layer on shorter timescales. Quantifying and predicting these climate feedbacks will first require a deeper mechanistic understanding of the factors responsible for varying transfer efficiency in the modern ocean than our statistical analysis provides. This might be achieved using realistic models of particle size spectra, ballasting, and remineralization (11, 32), constrained by our diagnostic flux estimates and further guided by novel in situ respiration measurements (35) and size-resolved particle counts provided by visual profilers (31).
I meant compared to present day values
There it is…
SJ, What’s your opinion on Gorsuch? I take his anti-EPA mother, Chevron criticism, and ruling upholding Colorado’s renewable energy standard as factors.
Don’t know much about him, so can’t say.
Yeah, I only know the things I mentioned above
Steven Chu. We’re not at 400. Closer to 5,
Dear Scott and ALL,
Note: this is a long read/watch on aspects of climate change, market-solutions, corporate leaders, and scientific integrity, and how this all might be inter-related.
I just watched a video of Michael Liebreich, Chairman of the Advisory Board of Bloomberg New Energy Finance (BNEF), who is presently considering running for the Mayor of London, giving the Keynote address at The Alliance of Conservatives and Reformists in Europe (ACRE) Blue-Green Summit a few days ago. ACRE calls their seven regional partners to be the US Republican Party, the Canadian Conservative Party, the Israeli Likud Movement, the Moroccan Istiqlal Party, Afek Tounes from Tunisia, as well as the New Zealand National Party and the Australian Liberal Party. In this video at 1:15 minute mark Liebreich says that he’s “proud to have been called a climate denier by Michael [E.] Mann”.
What is particularly disturbing to me is that Liebreich in a Twitter exchange called Mann “sloppy” and “appalling” citing as evidence of Richard Muller’s 2011 lecture in which allegedly Mann (remember “Climategate”?) uses ‘a trick to hide a decline’. Here is the video of that 5-minute segment:
However, this was thoroughly debunked by Peter Sinclair at Climatecrocks.com in this video, and John Cook below that:
John Cook at Skeptical Science in this article:
Peter Sinclair recorded this interview with Dr. Richard Muller in 2015 in which he admits he was wrong about climate science in 2011:
Thus, my question. Sorry for being so longwinded, but it’s really important to set the context.
Leibreich doubled-down after I pointed all this out to him, and suggested I read this book by Mark Steyn, titled A Disgrace to the Profession”. This book looks to me like US Senator Inhofe’s book, *The Greatest Hoax hit-piece on Michael E. Mann, full of climate denial propaganda, and some true. What’s your take on this book? Have you read it or heard anything about it?
A weird thing here is that Leibreich is the superstar of BNEF which positions itself as a leader in clean energy finance (including gas shale), but in reality he’s supporting climate denial sources. What’s your background knowledge of Dr Muller at BEST and his history of scientific integrity? Any clues?
I can tell you a few things. Mark Steyn is a loud-mouthed polemicist in the mold of James Delingpole. Steyn is the fill-in host of Rush Limbaugh’s radio show, which should tell you a lot. If you want a better sense of him and his book, he features prominently in the story I wrote after attending the Heartland Institute’s “skeptics” conference: https://arstechnica.com/science/2015/07/i-rejoice-that-it-is-warm-ars-attends-a-climate-contrarian-conference/
Steyn is the primary person being sued by Michael Mann for defamation.
Muller is a prominent physicist who voiced some arrogant doubts about climate science, leading up to that Berkeley Earth project. The scientists hired for that project did good work, and the results have validated all the existing temperature datasets. Subsequently, Muller has gone around claiming that “Well, it was perfectly reasonable to have doubts before, but now I’ve solved it.” It’s still self-aggrandizing arrogance, but I think he has dropped all the skepticism he displayed earlier (and to be fair, let’s give credit where its due) along with the conspiratorial insinuations.
Thanks for this reply, Scott. I PMed you a more detailed email for your thoughts. Cheers! Balan
World population is slated to hit 8 billion in the next few years. According to this article,
by about 2024. Optimistic, when you consider that we’ve been adding another billion souls roughly every decade since the 80’s, an interval that is decreasing as our breeding pace increases,
At the pace at which we’re reproducing, we’ll be hitting more DOUBLE the current world population by 2100.
But how many people is that really, put in a context we can all understand? If you placed all of us shoulder to shoulder in a single place, say New York City, our numbers would just about fill that entire area. Doesn’t sound too bad now, hmmm? Further, if we were stacked one atop the other, in a huge building in that same city, this is how large that building would need to be to accomodate us so far,
The first thing that comes to mind when we see this picture is, ‘Wow, there aren’t that many of us after all!’ The second thing that comes to mind is, ‘Damn, we’re a REALLY destructive species!’
SJ, What’s your opinion on the CH4 implications for the coastal waters in this Lena River study?: http://www.biogeosciences-discuss.net/bg-2017-22/
Not sure–too fine a point to interpret without synthesizing other work in the area.
As a massive sudden release of methane was the foundation of Guy McPherson’s predictions of Near Term Human Extinction, the release of this article brings that particular argument
to a conclusion,
Thus, climate change as a near term disaster for humans is, I think, greatly eased. In the long run, hundreds or maybe thousands of years hence, clearly there will be problems. Likely there will be. But, at least for now, at least in terms of human extinction, concerns, I think we can all relax.
Of course this says nothing about the long term degradation of our planet under our human scorched earth policy of running our civilization, and the extinctions of animal species are moving along at a nice clip. Perhaps someday we’ll evolve into a compassionate species before we are the only animals left standing.
John, (I don’t know if I’m welcome to make a science comment — if not I’ll just go away again).
Carol Ruppel is hardly a reliable source, judging by her comments on the Siberian crater eruptions, and her paper is just one paper, which doesn’t settle things in science (unless it’s J. Hansen :) ). Even Ed Duglokencky believes there has been an increase in seabed methane emissions in the Arctic, having progressed from a zero-increase stance, I believe.
As for GM, if you want to hold him strictly to his word of “extinction”, that would be pretty hard to accomplish short of all out nuclear war (not sure if that would even do it?), but if you’ll settle for collapse of civilization + deaths in the billions, that could easily be right around the corner with several meters of sea level rise which Hansen has shown is possible and arguably even likely without drastic near-term cuts in emissions. Certainly nothing you want to gamble on unless you’re playing with other people’s lives or maybe you just don’t give a shit.
And while the ice core record makes it pretty certain that there was no methane burst below +2C, we’re not that far away from that point, and even without a catastrophic eruption, “merely” losing our ability to control greenhouse gas levels dooms life on the planet at the centuries level. Is that not depressing enough for you? As the bard has said “the future is wide, wide open”.
Moderation didn’t hold this comment for me, so I’m not going to disappear it, but I’m definitely not hosting another round of “all the scientists Bill Shockley considers unreliable”.
Back to my shady spot then… bye all!.
You do know Ruppel was right about the craters? And where did Dlugokencky say that?
Can we leave this be, please? I told Bill he wouldn’t be allowed to argue about this here.
Huh? Are people being censored? I thought this was a no censor site. I think I must be the slowest guy in the world. I had no idea Bill was on the outs. Can’t imagine why he would be. Seemed like a pretty ok guy to me. I think I read most of the comments. As far as I knew, he didn’t say anything particularly egregious. Look at Nemesis. Now there was an abrasive guy and still he posted right along. I don’t get it.
Well anyway, thanks Bill for your comment. I read it and appreciate your thoughts, as I do everyone elses. I agree, it does appear that ice is melting. That appears to be the general consensus even among some scientists. I’m guessing the authors of the paper on methane were saying that even with ice melt, the methane isn’t going to be a problem because there’s a lot less of it worldwide than was previously thought. Also, as the ice melts and the oceans rise, the increased depth adds still further pressure on the hydrates below and adds more water the methane will dissolve in before it reaches the surface and is released into the atmosphere. So perhaps permafrost is the only real source of methane that can be a problem, but probably not much there either.
As far as human extinction is concerned, I’m guessing we don’t need methane for that to become a reality. We’re doing a fine job gradually but deliberately bringing that on ourselves. Just a thought – not that anyone asked.
Bill was asked to leave a long time ago—I think he was the first person to start commenting here. You’d have to dig back into the history to see why.
Nemesis was also asked to leave, though he/she has continued submitting comments intermittently. The moderation system grabbed your last comment because it included his/her name ;)
Unless Bill’s talked to Ed, then he’s blowing smoke. I’ve talked with him extensively and he’s never said seabed methane emissions are increasing. In fact, he’s said the exact opposite.
Human extinction will happen eventually, as it does for all species. I’m willing to bet it will take a long time though.
I see my post above is also awaiting moderation. The email is right. Am I on the outs as well?
Oh, well I don’t know how long your blog has been up. Probably long before I stumbled across it. Wasn’t Bill the guy who found all my old comments for me? I appreciated that. Seemed like an ok guy to me. But that’s just me.
Well anyway, hey, it’s your blog. You can run it any way you want. If I get annoying, let me know. I have a tendency to do that without even knowing I was. Usually get read out on it eventually.
You know SJ, I’m not really one of those hangers on kind of people. This is the only blog I comment on and I don’t actually much care if anyone else agrees or disagrees with a single word I say. Well, c’mon, I want to be honest. I care but I don’t care all that much. I ‘come here’ because sometimes I have something to say and no one who particularly wants to hear it. So I write it here. Important only to myself. I certainly don’t think one jot of what I say is going to change anything for the better. Lost that particular illusion decades ago. But I do always try to be honest even if it makes me look like a loon. Since people are so judgemental these days, thanks in part to our National Enquirer mentality some in the media have fostered, I expect a lot of people would agree with that assessment.
Hey, John. There is a long history with both Bill and Nemesis; if you’re truly interested, you can read through the old posts. I think Bill’s attitude and posting has changed for the better and I don’t mind him chiming in once in a while, but he did repeatedly, like Nemesis, really piss off a lot of folks making in hard not to ban them. In Bill’s case, he falsely accused Scott of some things which I don’t want to get into here. Check out the history. I must say, however, to be fair in my case, Bill has some of the best computer skills for retrieving past posts on this blog. Good on Bill for that. FWIW, Scott has got to be one of the most patient people I know in tolerating people who abuse this blog with their diarrhea-like postings after being warned repeatedly. Many folks asked for these folks to be banned, and Scott was very reluctant, and only did it as a last resort after God only knows (er, Bill knows) how many times they were asked to stop. Two key take-aways, 1) this blog is for discussing interesting stuff related to climate, McPherson, etc, not promoting political or personal agendas; 2) don’t falsely accuse others of things they aren’t guilty of without providing ample evidence.
SJ, what do you make of this modelling study concerning cooling of N. Atlantic waters?: http://www2.cnrs.fr/en/2881.htm
I would say that looks like a low-certainty conclusion. Note that they’re talking about a subset of the region separately from the Atlantic Meridional Overturning Circulation as a whole.
Hey Balan, nice to see you. I couldn’t agree with you more!
I think, in the grand scheme of things, there is a whole lot more going on in our world, both good and bad, then we ever individually realized. I’d rather focus on the good. Saw some videos lately of Paul Beckwith going after Guy McPherson (without actually naming him). I like Paul but I do have to say I think the intensity of these particular videos is just slightly disingenuous seeing as how he was saying something similar these past few years. I think people make mistakes. We’re not robots yet, though some are hard at work to remedy that situation. I think that this world would be a MUCH better place if we remembered that.
Things change, not often for the better, but sometimes, yes, for the better. When I was a kid, for instance, science told us that animals don’t love, they don’t care about anything but survival. Damn, they even said animals don’t feel pain, so experimenting on them in quite horrendous ways was A-OK. Like the infamous LD50 test. Sweet. What’s amazing is that now that they know better, THEY’RE STILL DOING IT. So I guess, as long as it’s convenient for us, a lot more animals will have to suffer and die. Do animals care? (I suggest muting the audio as it can get a little repetitious)
The point though, is that we can learn and adapt. Hopefully McPherson will too. My opinion, one of the last but one of the greatest things we can learn is to show a little understanding. Perhaps the greatest evolutionary jump we can make. By far.
This was rather interesting and I thought it might pique your interest as a hydrogeologist on CH4 and deep subduction zones: http://www.nature.com/articles/ncomms14134
Any thoughts on it?
I think it’s much more about what’s going on deep within the Earth than what affects the atmosphere. I’m not quite sure why they mention pre-biotic methane on the early Earth, though, because I think it’s clear that life showed up before proper plate tectonics… Cool though!
Thanks a lot! I have one more terrain question for you regarding permafrost. Does this strike you as surprising at all?: https://t.co/O93U8d3vdU?amp=1
Thanks for sharing personally about your childhood in this public forum; it’s a vulnerable thing to do and helps me get to know you better.
I think it was Gandhi who said you can judge a civilization by how it treats animals, and yes, I agree. We need to learn and understand more – a great reason for this blog. Thank you, Scott and all who contribute here.
I don’t think McPherson will change because he is well aware what he is doing – willfully misleading those who listen to him in the science of climate, in particular on methane. When you say Beckwith is “going after him”, did you mean Beckwith now disagrees with what McPherson is doing?
Yes, it does seem that Paul Beckwith disagrees with McPherson about the ‘danger’ of methane. If indeed it IS a danger. I wouldn’t know. But, the impression I get is that McPherson has said something that Beckwith took personally. I don’t know. But yeah, I don’t really care.
I grew up with a kind of consuming love for animals. Mostly because I saw the way people were treating each other and the planet as a whole. That has most certainly NOT gotten better as we’ve learned more about animals. I’ve always felt sad that our 4-footed friends always draw the short end of the stick on our eternal quest for profits. I don’t see that changing.
I’ve been hearing more about scientific solutions to the environmental mess we’ve created. Like mechanical bees.
Some are saying, hey, we don’t need bees. We’ll figure out how to pollinate the crops we need ourselves. No problem.
Bee optimistic: this drone can still pollinate plants even if all the bees die: Meet the artificial pollinators of tomorrow.
Now this kind of thinking is spreading to other aspects of the natural world. But I think in doing so, we’re losing an essential part of what makes our world so beautiful. It seems to be the way we think. Check out this new ‘solution’ to melting ice in the arctic. Some will most definately find in this something to celebrate. To me, though, it would be yet another sad milestone on our trip to a depressingly dreary Blade Runner world,
But hey, maybe that’s just me.
Fairly recent assessment of the methane issue.
Dramatic disintegration of Canada permafrost threatens huge carbon release
Permafrost, or frozen soil, is rapidly collapsing across a 52,000 square mile area in northwest Canada – about the size of the entire state of Alabama. New research from the Northwest Territories Geological Survey (NTGS) finds the permafrost thaw is intensifying, a dramatic disintegration that could speed up climate change.
Thanks for posting this, John. I was going to post it, but got too depressed. It came from Inside Climate News, a Pulitzer Prize-winning investigative news site where I trust the quality of the reporting, unlike AMEG. I’m really worried about this development and it seems to contradict earlier postings that there not so much to worry about. I think it’s important for all of us to thoroughly comment on this development as we’ve delved into CH4 permafrost emissions so much on this blog. Scott? Bill? Others? This link warrants in-depth discussion.
…”52,000 sq kilometers in rapid decline…”
Here is original article:
Yeah, same here. I don’t know what to make of a lot of the information out there. Not just on CC, but on just about everything we have our hands on. People say just about anything, whatever gets their view out there. Is methane a problem or is it not? I’m no scientist, but there are an awful lot of people on both sides of the argument who have opposing points of view. For whatever reasons. I tend to think, knowing our species, that we have to do some careful weeding to really understand what’s happening. Trust no one.
My honest guess is that methane is more of a problem than some say, less than others say. Question than is, is that enough to make life unpleasant in the near future? I think we just have to sit back and see.
One thing is clear, things aren’t getting better in a hurry.
Balan and John,
I talked with Merritt Turetsky about this: https://twitter.com/queenofpeat/status/837494057203077120.
Short version, certainly something to keep an eye on, but not unexpected
Thanks Bryant. Yeah, I’ve pretty much come to the conclusion that when there are two sides to an argument, choose the middle.
SJ, have you heard that story about the G20?
Sorry, never got a chance to find out much about that.
It was a reference to this: https://www.bloomberg.com/news/articles/2017-03-09/g-20-document-shows-governments-retreating-from-climate-funding
Not really sure if it’s a copout or tactic to test Trump
