  1. Interactive: What is the climate impact of eating meat and dairy?

    I'm disappointed to see such misinformation here, I expect better. Imo, anyone using 100-year carbon dioxide equivalent emission factors for methane should probably be ignored, or at least not be published.

    Here are some better atricles on a similar subject:

  4. Startups aim to pay farmers to bury carbon pollution in soil

    Am wishing to donate, but running into trouble with Experiment.com

    (and am not wishing to use facebook)

    Attempt No.1 produced the Rotating Colorwheel of Death (or Capture?)

    Attempt No.2 produced a Whoops Connection Problem.

    For a klutz like me, one strike produces suspicion - and the second strike produces paranoia.  Can friendly experts advise?  Is there a Plan C (without Paypal) ?

  5. Startups aim to pay farmers to bury carbon pollution in soil

    That is a worthwhile question. Good for you on persistance. Adding my ducats.

  6. Startups aim to pay farmers to bury carbon pollution in soil

    What harrowing rollercoaster ride, RedBaron.  But here you are, on the other side, or at least successfully and solidly at the next stage. 

    I'd not revisited this thread since my original comment (thanks for the pointer, Baerbel). I have to say I was extremely dejected during the period of your narrative where it seemed experiment.com had ceased operations. It's a great outfit— I've "participated" in several projects there, always with a satisfactory outcome.

    We'd be interested in publishing a guest blog post about this. Not only is your project quite interesting but the story of how you've persisted is pretty inspirational.

    As well, for others it might be helpful to learn about how the process at experiment.com works, from a hardened veteran. In particular it would be fascinating to hear about the peer review process.

    If you're interested and have the time, please contact us via the contact form

    For the rest of us: if you've got a few ducats to spare, head over and progress RedBaron's experiment. It takes only a few minutes of your time taken from tapping and swiping dismal headlines and the sacrifice of a deluxe but fattening pizza's worth of money to make the world better.

    @4 doug_bostrom and all others who supported my efforts,

    I have great news! It took a 6 month delay due to covid, and months in peer review by their science team, but I finally was able to launch the science fundraiser project! It went live yesterday.

    What is the rate a new regenerative agricultural method sequesters carbon in the soil?

    I would appreciate very much help from any of you that understand better than me how to share this, Advertising is unfortunately not one of my skills. It was hard enough for me to develop the methods and design the scientific tials!

    Oh and BTW one of the first questions everyone asks me when they see this is why the grass between the crop rows? In this case a picture is worth a thousand words.

  9. CO2 emissions do not correlate with CO2 concentration

    Gerard Bisshop @5,

    The time for half a CO2 pulse to be drawn-down out of the atmosphere into oceans & biosphere is dependent on the size of the pulse. The graph you link to (from Joos et al 2013) showing 30yr is for a 100Gt(C) pulse, so a pulse equal to a decade's worth of anthropogenic emissions. Anthropogenic emissions are approaching 700Gt(C) and models for a 1,000Gt(C) pulse or 5,000Gt(C) pulse show it takes much longer to reach that 50%-of-pulse level, perhaps 150y & 450y respectively (eg Archer et al 2009), thus making the draw-down numbers more at odds with Af=45% (which means 55% is removed within the year).

    The 'circle' is squared because Af is a measure of the annual draw-down compared with a single year's emissions. Draw-down value is of course dependent on far more than a single year's emissions, indeed dependent on the emissions accumulated over the previous decades. So that 55% comprises, say, 2% of Y(0), 1.5% of Y(-1), 1.25% of Y(-2), 1% Y(-3), etc, these all adding up to 55% of Y(0). If we did manage to zero emissions in 2021, draw-down would continue, the atmospheric CO2 would thus drop and the calculation of Af would require a division by zero.

    GWP numbers by definition yield GWP(CO2)=1 and use the forcing resulting over a specified period (eg 100y) from 1t(CO2) released into the atmosphere after draw-down is factored in, a draw-down which is dependent on expected accumulative totals of CO2 emissions. The level of draw-down is not considered set in stone and still subject to research. For instance CarbonBrief have coverage of a recent paper reassessing the ocean drawdown. So far, the GCMs do not model the carbon cycle (and of course have to assume future anthropogenic emissions fo all GHGs) so the level of CO2 (and other GHG levels) are inputs assumed for each GCM run.

  10. CO2 emissions do not correlate with CO2 concentration

    Can you please explain more about the airborne fraction of CO2? The models of CO2's atmospheric lifetime show that half the original CO2 emission is taken up by the oceans and vegetation in about 30 years. But according to the global carbon budget and the airborne fraction, 55% or so is removed from the atmosphere each year.

    So for emission scenarios of different sectors or gases, how is the airborne fraction factored in? GWP calculations, for example, rely on the AGWP or each gas compared to the AGWP of CO2, so is CO2's AGWP devalued by the airborne fraction when compared to, say, methane from fugitive emissions (leaks).

    This would not be an issue for climate models I imagine (because they work on the CO2 in the atmosphere), but for any analysis of sectors or gases it must make a difference.

  12. Why does land warm up faster than the oceans?

    ray_climate:

    It would be helpful if you provided a link to the diagrams you are pondering about, but...

    ...to provide a diagram of net flows between land and ocean would require that these values be calculated. I suggested a method that allows an approximation of the latent heat (water vapour) flux. No such simple method applies for thermal fluxes, and those fluxes are not rotuinely measured.

    Weather and climate  models would have such horizontal flux numbers imbedded in their calculations, but to sum them up in a land<-->ocean manner would require a lot of work - starting with outlining all the boundaries between land and ocean in a manner that would allow tracking of fluxes over time.

  13. Why does land warm up faster than the oceans?

    Bob Loblaw @4. I appreciate that helpful and thorough explanation. Regarding the ocean/land analogue of the Trenberth diagram, I appreciate the fact that we live in a 3-dimensional world with 3-dimensional processes. However the same comment applies to the [land+ocean] Trenberth et al diagram, bu it is nonetheless very useful as attested to by the numerous times climate scientists reproduce it. So I would still like to see  two side by side energy flow diagrams I referred to.

  14. Interactive: What is the climate impact of eating meat and dairy?

    JWRebel @1

    Thanks for the heads-up! The issue should be fixed now and the printable version of the blog post shows up again.

  15. Interactive: What is the climate impact of eating meat and dairy?

    Quite frankly these numbers are useless for a large number of people that aren't sourcing their food that way(which is sort of acknowledged). I just don't see how the numbers can hold up. beef cattle vs dairy really? or sheep or chicken or pork? I've raised them all and can tell you that the energy inputs for beef cattle can consistently be way less than above. Sheep and goats might be slightly more efficient grazers but they make up for it in size comparisons and surface area to volume ratios

  16. Interactive: What is the climate impact of eating meat and dairy?

    The printable version is the wrong reference, produces empty page for interactive feature. This comment intended only as signal before being deleted.

  17. Why does land warm up faster than the oceans?

    ray_climate @ 2:

    The most obvious horizontal transfers of energy between oceans and land masses is related to the hydrological cycle.

    • Preciptiation over land greatly exceeds evaporation from land.
    • Evaporation from oceans greatly exceeds preciptiation over oceans
    • The size of the difference can be measured by total runoff from rivers into oceans.
    • Every bit of liquid water that runs off land into oceans need to be replaced by water vapour transported from oceans to land (and falls as precipitation over land).
    • Evaporating water from oceans requires energy input.
    • Condensation of water vapour to form clouds releases that energy.
    • The end result is a transfer of energy from oceans to land areas (or the overlying atmosphere).

    Thermal energy is also transported horizontally by atmospheric circulation.

    All this happens in a three-dimensional world. One-dimensional or two-dimensional images can be limiting.

  18. Why does land warm up faster than the oceans?

    Darinscoop,

    CO2 gas is evenly distributed throughout the atmosphere.  The molecules do not form clusters but are evenly mixed.  Heat is evenly absorbed according to the concentration of the greenhouse gasses.  As you increase in height from the surface the pressure decreases and the concentration decreases.  If you read a description of a layer of CO2 it was probably a simplification to make the idea of energy absorbtion easier to understand.

    I am not sure what your question about boiling water is asking.  It is possible to boil  water by heating the sides or top of a container.  The energy flow in the atmosphere is: Sun- surface- atmosphere- outer space.

  19. Why does land warm up faster than the oceans?

    An excellent post! But the differential cannot go on increasing indefintely. Basic thermodynamics suggests a net transfer of flux from land to ocean.Is this via atmospheric circulation? what is its characterisitic? What is the approximate current value of this net flux?  

    We are all familiar with the wonderful Trenberth et al pictorial of the global energy budget. A variation showing two such diagrams, one for ocean, one for land, with the aforementioned flox indicated would be a great adjunct to this post. Does such exist? Any climate scientist willing to provide such?

  20. Why does land warm up faster than the oceans?

    As far as CO gasses creating a shielded heat layer between the the surface and the earths atmospherer, it's difficult to think of molecular clustes chaining together unless the gasses lie on a 2-dimensional plain.  Wouldn't heat tend to escape through any means of CO gasses if clusters exists at differing elevations?   Also, have you ever try to boil water from a heat source that either came from the top or the sides of the container?  I'm still trying to understand this logic.

  21. 2020 SkS Weekly Climate Change & Global Warming News Roundup #38

    This Guardian news article describes a poll where 70% of voters were  in favor of climate action.  The article claims that this result indicates that in the upcoming election politicians who are climate deniers will suffer from voters who want climate action.  

    I hope that is true.  Even if it is not true this election, this is a much stronger result than polls in the past about climate action.  More politicians are discussing renewable energy and other climate actions.  Hopefully we will start to see real action with the next presiident.

    Michael Sweet & nigelj: Your recent exchanges remind me of the old-time radio show of my youth, The Bickersons

    Per Wikipedia:

    The Bickersons was a radio comedy sketch series that began September 8, 1946, on NBC, moving the following year to CBS where it continued until August 28, 1951. The show's married protagonists, portrayed by Don Ameche (later by Lew Parker) and Frances Langford, spent nearly all their time together in relentless verbal war.

    "In your comment you suggest people will think that 1-2 trillion dollars per year is expensive for a renewable energy system."

    I did. Its obvious because $ 1 trillion dollars sounds a lot to the average person. It needed to be put in context that it is only 1.5% of gdp, and right at the top of the article. However those people who read the whole article would see that it isn't such a large sum, so your comments are not really connected to the point I was making.

    "You do not consider what fossil energy would cost....."

    Where do I not consider that? I know perfectly well what a fossil fuel system would cost, a great deal as you correctly point out.

    Please stop telling me things I already know. Please stop implying Im not aware these things, or that I disagree with these things. 

    It might help if you had said "people should consider...." Is that what you meant?

    "In the report cited they say that a renewable energy system will cost less than a fossil fuel system. "

    I have read the report. I said its "a good report". So obviously I agree with the report.

    I mean with all due respect, what the hell are you going on about?

  29. 2020 SkS Weekly Climate Change & Global Warming News Roundup #38

    Nigelj:

    In your comment you suggest people will think that 1-2 trillion dollars per year is expensive for a renewable energy system.  You do not consider what fossil energy would cost.  If fossil energy costs 3 trillion dollars per year and renewable energy costs 2 trillion dollars per year than the renewable energy is a bargain.  In the report cited they say that a renewable energy system will cost less than a fossil fuel system.  In addition, the reduction in pollution from using renewable energy will save trillions of dollars in costs, especially health costs and climate costs.

    You cannot look at just the cost of renewable energy.  You have to compare the cost of renewable energy to the cost of fossil energy.  This is a common mistake people make when looking at energy systems.

  30. 2020 SkS Weekly Climate Change & Global Warming News Roundup #38

    Michael Sweet @2, what possible relationship does that have to anything I wrote? Where did I imply continuing fossil fuel use is free?

  31. 2020 SkS Weekly Climate Change & Global Warming News Roundup #38

    Nigelj:

    Keep in mind that even if we continmued using fossil fuels energy would not be free.  It would cost about the same to keep using fossil fuels except there would be all the health and environmental damage from fossil fuels.  In addition, fossil fuels are starting to run short and prices would increase by 2050.

  33. 2020 SkS Weekly Climate Change & Global Warming News Roundup #38

    The editors choice article is really good but one nit pick. It starts out by saying "The world must get to net-zero carbon emissions by mid-century, and can make it happen for a cost that is relatively small in global terms, $1 trillion to $2 trillion per year, a new report has concluded."

    Most people will go WTF $1 trillion is not small. And we know many people only read the title and first couple of paragraphs in articles.
    It would have been better to include the text from further into the article that this is only 1.5% - 2% of gdp. Get this right at the top of the article.
    Think of your audience!

  34. Berkeley study: 90% carbon-free electricity achievable by 2035

    Yes, I had read the report. It's why I posed the question.

    You need to go to the appendix to see their discussion of  "IMPACT OF HIGH ELECTRIFICATION"

    "In our modeled cases, we assume future load shapes will be
    similar to today’s, largely driven by commercial activity (work
    hours), seasonal changes, and especially by air conditioning
    demand in the summer."

    https://www.2035report.com/wp-content/uploads/2020/06/2035-Appendix.pdf?hsCtaTracking=3c511c2d-f42d-4b95-b726-a4a3d5285e40%7C134cbd02-c665-4ee0-ad95-492f4b5a55d2

    They do a sensitivity in the Appendix on 'High Electrification". Instead of 1200 GW of cumulative new additions to 2035 they forecast a need of just over 1600 GW.

    Also:

    "Note that we do not consider any load flexibility, which
    significantly underestimates the overall system flexibility
    available in the model."

    I am guessing they did not consider Vehicle to Grid

    nigelj, I haven't read his book: like most normal people.

    You have to admit I was attacked for my very reasonable points of view and then moderated whilst my attackers were not.

    Atleast you understand I have valid points. If you find them contendable fair enough but none-the-less you have still found them valid unlike your moderators who are obviously biased.

    Going to your first paragraph: I'm basically saying it was a deliberate strategy and that seems to be the very point I was attacked for by multiple opponents and then finally the moderator himself. How can anyone have a discussion on this forum when there is no discussion allowed?

    Sure you can say there would have been discussion anyway... that doesn't take one iota away from my reasonable pov? Only to an extremeist would it nullify my pov, which you seemingly seem to agree with to aleast some degree- unlike others.

  38. Participating in Al Gore's Climate Reality Leadership Corps Training

    Keithy @53, Al Gore may well have helped motivate the denialists in America, to an extent, for the reasons you suggest. Im not so sure it was a deliberate strategy.

    And I would suggest the denialists would have been very active anyway even if he didnt exist, given the media have run numerous articles on the science, and given there are plenty of denialists in other countries where his book and movie have only been seen by a tiny minority of people. 

    Do you see it differently? If so why? Its just that its hard to understand where you are really going. What do you think of his book?

  40. Berkeley study: 90% carbon-free electricity achievable by 2035

    Papawhisky:

    On page 21 of the report they say:

    "Our modeling approach represents a conservative strategy for
    achieving 90% clean energy. Various complementary approaches
    could help achieve this deep decarbonization, with potential for
    even lower system costs and accelerated emissions reductions.
    Demand-side approaches include demand response and flexible
    loads, such as flexible electric vehicle charging and flexible water
    heating—which could play a large role if building and vehicle
    electrification occurs more rapidly than envisioned in our core
    cases."  My emphasis.

    It appears to me that they have some transportation electrification (I did not try to find out how much transportation electrification they use).  They say this electrification could progress faster and more renewable energy could be accomodated.

    According to Connelly et al 2016, when larger parts of the economy are electrified it allows a greater percentage of electricity to be renewable and less storage is required.  Connelly et al use electromethane for storage which would complement the proposal described in the OP.

  45. Participating in Al Gore's Climate Reality Leadership Corps Training

    Keithy @48,

    It would be good if you could be specific about what Gore did to 'light this conversational fire'.

    If it is the 2007 'An Inconvenient Truth' film then you will have an uphill battle getting any agreement here as this is very late. Perhaps you do have some specific denialist response post-2007 in mind, but we idiots here are not mind-readers.

    My 'touch of unreasonability' was prompted by the possibility that you were putting the Gore 'ignition' at an earlier date. He had run for the Democratic nomination for President in 1988 and was a well-kown AGW campaigner through the 1980s and, of course, did become vice-presidential candidate in 1992. But again, if that is the period you have in mind, along with some resulting girding-up of the denialist effort, we are not mind-readers and without any assistance of what you actually mean, I for one see no such earlier process at work.

    And I'm at a loss where the wind turbines come in to all this.

  46. Siberia’s 2020 heatwave made ‘600 times more likely’ by climate change

    Luiz:

    As the OP states "the methods used in the analysis have been published in previous attribution studies."  The methods used have been validated.  It takes 6 months to a year to get published in a peer-reviewed journal.  Scientists have found that if an article is published in 2020 that says in 2019 there was record heat no-one pays attention.  They have developed methods to analize data in real time.  Then they are able to get the news out while the problem is still ongoing.

    Citing a study of a conservative hoax and comparing it to established science does not really make much of a point.  The point here is that science was able to rapidly evaluate the conservative hoax and determine that it was incorrect.  By contrast, the climate claim was based on a method that has been peer reviewed.

  47. Participating in Al Gore's Climate Reality Leadership Corps Training

    Great, MA Rodger, but don't you think you're becoming a touch unreasonable, if not abstract yourself, as toward my argument?

    I just said Al Gore lit the conversational fire and the deniers kept it going by forced move... now we have multi megawatt wind turbines as a result- plus much more- to thank him for!

    I thought my idea was quite straight forward to follow actually, instead there seems to be a whole team of idiots on here set to bark at anyone daring to have a brain cell that dare deviate from the whistle blown song sheet.

  48. Participating in Al Gore's Climate Reality Leadership Corps Training

    Keithy @46,

    We can actually go back further than 1976. Gore was aware of AGW science from his university days (so back in the 1960s) when he was taught by Revelle. And there is the incident of Revelle's name on the Fred Singer 1991 Cosmos article which has often been wielded by denialaists against Gore. And I do recall some saying the reason for Singer getting the aged Revelle's co-authorship on Singer's article was actually because of Al Gore's prominent AGW activism within the politics of that time and Gore's association with Revelle.

    "The findings are yet to be published in a peer-reviewed journal."

    Why not wait before posting and avoid the embarrassment of a retraction?

    Like this pathetic one:

    Well, MA Rodger , I give you credit for not concluding I'm a machine or whatever those other blokes seem to have summised - but I will check out that link... I never knew Gore was into that far back. 1976 is when I was born.... 

    Oh yeh, Motorhead and the LX Torana came out that year!
