Berner authored those first graphics at the RC link. Here's the same image, with his comments about the overall correlation between atmospheric carbon dioxide and global temperatures over geologic time:
Of course, the Royer graphic also corrects for the Faint Young Sun and ocean pH changes over the same geologic timeframe, with the result of strengthening the correlation between those CO2 levels and global temperatures over geologic time:

@ 688 John,
I found that this denier took it from wattsupwiththat blog site. (a blog site known for climate denialist propaganda)
I also found this in searching more about that graph.

TVC15 - I would say likely it is from here. The graphic itself has the source references for its data. In denier space, this usually goes with arguments that CO2 isnt related temperature - ignoring all the other drivers of climate.
The NPR article was on the Marcott 2013 paper, extensively discussed here. Put Marcott into the search box on top right. A criticism is that the methodology may not capture high frequency temperature change. The usual denier take is to point major spikes in the NH temperature record (eg Younger Dryas) associated with exit from glacials. There is some evidence of similar, anti-phased events, in SH record. These proxies to indeed indicate very rapid temperature change but I am not aware of evidence for a global temperature change of that speed as opposed to regional change. Mechanism is disputed, but is associated with end of glacial periods so relevance to present climate is doubtful to say least.

Can you guys tell me where this graph originated from? A denier is trying to use it to claim that there's no correlation between earth's CO2 levels and climate change in either direction (warmer or colder). And that's true over earth's 4+ billion year history.

I have a question about the EPIC ice core data showing that the climate for the seven prior interglacials. The second denier I'm dealing with is stating:
"The reason it was 14.4°F warmer in Greenland than it is now is because during the last Inter-Glacial Period, the average global temperature was 73.7°F and not the current 58.4°F."
When I disclosed that the the EPICA ice core data (which covers back to eight previous interglacials) doesn't manage the 4.3°C to 8.3°C relative to today for seven prior interglacials.
He comes back with this: "Um, those are the temperature changes in the Antarctic, not the average global temperature."
My understanding of the EPICA Ice Core datas main objective is to obtain full documentation of the climatic and atmospheric record archived in Antarctic ice by drilling and analyzing two ice cores and comparing these with their Greenland counterparts (GRIP and GISP). Evaluation of these records will provide information about the natural climate variability and mechanisms of rapid climatic changes during the last glacial epoch.
What game is this denier tyring to play with me?

Thanks scaddenp. He's the same denier who says CO2 is a basic building block of life. *rolled eyes*
The other denier I'm dealing with uses odd angles to come at me with.
"I guess you see only what you want to see.
Past Century's Global Temperature Change Is Fastest On Record
Past Century's Global Temperature Change Is Fastest On Record
It's not the fastest on record.
24 times in the last 100,000 years, the climate has fluctuated by as much as 20°F in a matter of years or decades.
78 times in the last 100,000 years, the climate has fluctuated by smaller amounts 4°F-6°F in a matter of years or decades.
Explain how 1.4°F over 140 years — 14 decades — is faster than that.
If I had to list every alarmist claim by NASA, or NPR, or National Geographic or the IPCC, I'd be here the rest of my life."

A wrap-up comment related to my comments @7 and 8:
Climate science has unintentionally exposed a significant required correction of what humans have developed. The Present is significantly morally corrupted. That is the fundamental reason for the difficulty climate scientists face in their efforts to improve awareness and understanding.
The awareness and understanding presented by Stephen Gardiner is not fundamentally new. It is a rigorous presentation of fundamental understanding that has been presented in the past. A recent clear presentation of the understanding was in the 1987 UN Report "Our Common Future" (24 years before Gardiner published his detailed presentation of the Moral Corruption Storm). And the fundamental idea was also presented by many people before that time. One of those presentations was by John Stuart Mills back in the 1800s.
In "On Liberty" Mills stated "If society lets a considerable number of its members grow up mere children, incapable of being acted on by rational consideration of distant motives, society has itself to blame for the consequences."
Gardiner's Global Storm is regarding a location-based Distant Motive (concern for Other locations on the planet). And his Intergenerational Storm is a time-based Distant Motive (concern for the future). And a third Distant Motive would be related to consideration of Other Life including Other people (an item mentioned by Gardiner as an issue covered/impacted by the Perfect Moral Storm).
That understanding was summarized as follows in opening section of "Our Common Future":
25. Many present efforts to guard and maintain human progress, to meet human needs, and to realize human ambitions are simply unsustainable - in both the rich and poor nations. They draw too heavily, too quickly, on already overdrawn environmental resource accounts to be affordable far into the future without bankrupting those accounts. They may show profit on the balance sheets of our generation, but our children will inherit the losses. We borrow environmental capital from future generations with no intention or prospect of repaying. They may damn us for our spendthrift ways, but they can never collect on our debt to them. We act as we do because we can get away with it: future generations do not vote; they have no political or financial power; they cannot challenge our decisions.
26. But the results of the present profligacy are rapidly closing the options for future generations. Most of today's decision makers will be dead before the planet feels; the heavier effects of acid precipitation, global warming, ozone depletion, or widespread desertification and species loss. Most of the young voters of today will still be alive. In the Commission's hearings it was the young, those who have the most to lose, who were the harshest critics of the planet's present management.The winners in politics and business have no defence for failing to be aware of this understanding and how it relates to their actions, especially today (and little defence for being unaware since 1987).
Gardiner, and so many others, point out that what is lacking is institutions that will hold the morally corrupted accountable and penalize them for failing to help improve awareness and understanding in pursuit of sustainable developments for the benefit of the future of humanity.
And the lack of such institutions can be understood to be the developed result of moral corruption being allowed to Win. Because the Winners establish what the Institutions will be and what they will do.
The fundamental rule of Ethics is "Do No Harm". The aspiration or objective of being Ethical is to "Help Others". That leads to an understanding that:
- being Ethical is restricted to 'only those actions that Do No Harm to Others, including not harming other life because Others may depend on that Other life as an essential part of the intricate web of life'. Only actions helpful to Others are Ethical.
- One person or group cannot ethically benefit if their actions will harm any Others. And future generations are Others.
The current generation faces an ethical dilemma. The actions of past generations have developed popular and profitable activities that are understandably harmful and ultimately unsustainable. How is that incorrect development to be corrected? (because it undeniably must be corrected). The Perfect Moral Storm'spowerful motivation toward Moral Corruption must be able to be Over-powered by Good Helpful people or there is no future for humanity, and that is clearly not an acceptable future option.
Clearly, to the greatest degree possible, the continued harm to others must be reversed. The damaging intergenerational cycle of moral corruption must be broken. Those who have become the most fortunate by benefiting from harmful unsustainable activity must be required to lead the correction, including giving up some of their developed perceptions of status relative to Others.
A likely required correction is that Status would be contingent on how helpful a person is. Anyone not wanting to lead that way should have their wealth and influence legally corrected to match the degree of responsibility the person is choosing to want (there being no expectation of helpfulness from the poorest).
Richer more influential people must morally be required to:
- develop the ability to have lower impact lives than poorer people
- put more effort into helpfully improving awareness and understanding.
- sustainably help the less fortunate live decent lives
They cannot be allowed to remain Richer and more Powerful if they choose not to be more ethical than Others.
And that required correction has been unintentionally exposed by climate science. It is the fundamental reason for the difficulty climate scientists face in their efforts to improve awareness and understanding.

ExxonMobil shareholders will not get a vote on whether the company should set targets for cutting its greenhouse gas emissions, following a ruling by the Securities and Exchange Commission.
New York State’s pension fund and other investors had called for the oil company to start setting targets for reducing emissions in line with the goals of the 2015 Paris climate agreement.
But the SEC ruled on Tuesday that Exxon could keep the proposal off the ballot at its annual shareholder meeting next month.

Exxon have been notorious liars and will probably lose their lobby registration at the EU-Parliament therefore.

michael sweet at 22:05 PM on 3 April 20193 clean energy myths that can lead to a productive climate conversation
Thinking Man,
I note that you show no math or citations to support your wild claims.
I have seen several attempts by wind opponents to calculate very high costs of wind using absurd assumptions like you describe. About 5 years ago one was published in a journal. No-one refers to that article now because everyone informed knows that it was BS from the start.
In spite of these calculations, in Texas and New England wind energy underbids all fossil fuels including gas. Real world experience indicates that wind is cheaper than all fossil fuels.
ps: I thought that the 6 day in advance estimates of wind energy were pretty good. Since utilities use these for routine planning if a fossil plant that is on standby is forecast to be needed 6 days in advance they have sufficient time to get the fossil plant online. The one day (or one hur) forecasts are the ones that control what is done in the end. Everyone knows that forecasts are not as accurate beyond 4 days. Claiming a 6 day forecast is important is a strawman argument.

One Planet Only Forever at 15:04 PM on 3 April 2019Protecting oil companies instead of the climate-vulnerable is elitist
I will add an important point to my comment @7.
Perceptions of prosperity or reduction of poverty that are the result of unsustainable and harmful pursuits cannot be expected to continue as benefits into the future.
That is an inescapable reality. Unsustainable harmful pursuits have a competitive advantage when the measures of 'value' are popularity or profitability. Once valid ethics is introduced (not claims about morality that are just poor excuses for harmful unsustainable pursuits) everything changes.
The current developed world has become highly morally corrupted. Misleading marketing is a major reason. Politics being a free-for-all regarding misleading marketing has only made things Progressively (and Conservatively) Worse.
Progressive development of sustainable improvements, and related corrections of what has developed based on constantly improving understanding, is compromised by the easy popularity of resistance to correction, the resistance to learning, the resistance to changing an incorrectly made-up mind.
The resistance to correction has made many problems worse. The result is the development of requirements for more traumatic corrections. The required corrections today are larger and more urgent that they were 30 years ago.
The key to improving the future is to make the corrections earlier, and ensure that the reduced trauma of the correction (reduced because it was started earlier) is experienced by the people who benefited most from the creation of the problem before the corrections started to be implemented.

Talk of the limitations of electric cars is interesting. But the reality is that electric rapid transit was effectively implemented about 100 years ago.
And debating technical details regarding climate change and responsible actions is interesting, but can be a damaging distraction.
And claiming that the choice is 'reduce the harm done to future generations' or 'help the poor today by doing more harm to the future generations' is clearly a false choice. Poverty and reduction of future climate impacts can been achieved simultaneously, at the expense of people who gained status in ways that are not sustainable, ways that create poverty and climate impacts.
The reason there is still poverty in a nation as collectively wealthy as the USA has a similar cause as the reason such a wealthy nation has such powerful resistance to behaving better regarding climate change. And it is similar to the reason there is poverty in any nation (almost every nation has wealthy people and deep poverty).
And that brings me to the point of referring to a book I highly recommend to people who want to better understand what is going on, regarding more than climate change, but with climate change as a powerful case study.
"A Perfect Moral Storm: the Ethical Tragedy of Climate Change.", by Stephen Gardiner published in 2011, is a comprehensive and hard to argue against presentation of the ethical issue (the moral corruption of leadership) that climate science has exposed in a big way.
The 2016 SkS Weekly News Roundup #3 included the following presentation by Gardiner:
Why climate change is an ethical problem by Stephen Gardiner, In Theory, Washington Post, Jan 9, 2016
It is an updated summary of the thinking he presented in his book. But some here may remember that back in 2012 his book played a key part in the following SkS item posted by Andy Skuce in 2012: "Changing Climates, Changing Minds: The Great Stink of London"
In that item a series of points regarding climate change impacts are presented and followed by the following:
"In his recent book A Perfect Moral Storm, The Ethical Tragedy of Climate Change, Stephen Gardiner identified three “storms” that come together in a wicked synergy to make the climate crisis an especially intractable problem.
- The Global Storm. The unequal dispersion of cause and effect across the planet. See b), c) and d) above.
- The Intergenerational Storm. The effects of our emissions are deferred and will persist essentially for ever on historical timescales. See e) and f) above.
- The Theoretical Storm. We currently lack the institutions, conventions and tools—political, moral and economic—needed to tackle the exceptional problems posed by climate change and we are going to have to invent them as we go along. See g) above.
"After this analysis it shouldn’t be difficult to appreciate why we’re not doing any better than the Londoners were in 1855. Actually, to quote climate scientist Ray Pierrehumbert (pdf):
So far, we’re not doing any better than cyanobacteria."
The Green New Deal is proof that some people are trying to do better than cyanobacteria. But they still face massive resistance from morally corrupted wealthy people and the type of leadership the morally corrupted want.

TVC - you are wasting your time with this idiot. Your graphic is based on some fundimental physical assumptions, especially the conservation of energy. From this we deduce that changing the radiative balance will change climate. Measuring individual contributions to the radiative balance does indeed yield that diagram. It is possible to construe a possible downward trend in solar, but he thinks a change of 0.1W/m2 is significant then why isnt change of 3.7W/m2 (GHG) even more significant. The claim "that we "know" that the only thing that really matters is CO2?" is strawman. Reading any of the references associated with the diagram shows that all the causes contribute and are accounted for - but that CO2 is the most important for current climate change. He is not interested in examining the evidence. He needs to supply evidence that refutes the methodology or finding of those papers. I doubt you get him to read any of them.
His comments present not one shred of evidence in reply. It is scoffs from personal incredulity based on wilful ignorance. You will not make any impact on someone who chooses not to understand.

"That is priceless. So I guess the fact that we are in a 50-75 year solar minimum cooling phase is lost to you then? Should we not be concerned about that large burning gas ball in the sky, now that we "know" that the only thing that really matters is CO2?"

Sometimes governments have "picked winners" and so backed things that have failed, but so has the private sector, with numerous examples in the technology area. Picking winners is an inescapable part of life.
The private sector has backed fossil fuels just as much as governments.
Governments can minimise picking winners by treating all forms of renewable electricity generation the same.

Dana's article is really good, but it unfortunately it looks to me like a carbon tax and dividend isn't gaining much traction in America. Perhaps there is just too much ideological paranoia about taxes for it to ever work.
The government infrastructure spend in the GND might be the only thing thats viable. The senate have voted down the GND but a government spend at realistic levels might be viable. Subsidies around the world for wind power etc have yielded results. The GOP is quite happy to subsidise things when it suits and run deficit financing.
It's troubling though because without a price on carbon things become complicated.
America's climate policy is a train wreck.

"Nevertheless, for all the competition and technical input to electric car design, the weight to range ratio of lithium-ion batteries places practical limits on the utility of electric cars when compared to ICE cars."
Yes and no. The 2019 nissan leaf electric car is moderately priced, and can go 150 miles on a full charge and a new model available shortly will do 200 miles. This is quite sufficient for work and travel for the vast majority of people, assuming some recharging stations. The venerable toyota corolla can go 500 miles on a full tank of gas, but this is largely superfluous unless you do very long trips somewhere with few petrol stations, and not many people do this. So the difference between the two cars is psychological rather than real.
In addition 10 disruptive battery technologies are under development and some will no doubt extend range for those needing 500 miles. Even if some of these fail, and being careful of getting carried away technological hype, it still looks very promising. So consciousnessof sheep is too pessimistic for me as well. But the article on Britain as Venezuela is interesting. Just chose it at random.

ThinkingMan at 00:33 AM on 3 April 20193 clean energy myths that can lead to a productive climate conversation
LEVELIZED cost estimates can be used as a starting point for estimating the cost of electricity service which society currently expects. Electricity users expect reliable service. In TX, the full cost (capital related charges + operating costs) of reliable electricity structured around wind turbines is at least 1.75x the full cost of reliable electricity generated by natural gas fired combined cycle combustion turbines. In New England, the multiplier is 2x.
The multipliers were estimated using EIA levelized cost estimates, wind turbine capacity factors for both regions, hourly wind power data for both regions plus a simple financial model. The wind turbine package was designed to generate a constant amount of electricity, for simplicity's sake. "Package" means the mix of thermal generators backing up wind turbines. The multipliers are intended to be ball park estimates.
PREDICTABILITY of wind turbine output: Day ahead and longer wind power forecasts leave much to be desired across North America. Your attention is directed to https://www.aeso.ca/grid/forecasting/wind-power-forecasting/ . Go to the "Monthly Wind Power Forecast vs Actual Comparison". "aeso" is the Alberta System Operator. Results are similar for Electric Reliability Council of Texas and ISO New England.

"Electric cars – powered from on-board batteries – have been around since 1859. However, they were quickly eclipsed by internal combustion engine (ICE) cars which even then offered far greater speeds and ranges. The early electric cars drew their limited power from lead-acid batteries of the kind found in most ICE cars. And while improvements continued to be made to electric motors, it was battery storage that proved to be the limiting factor for electric cars. The development of modern lithium-ion batteries – coinciding with the global drive to curb greenhouse gas emissions – helped propel Elon Musk’s high performance (and once again massively subsidised from the public purse) Tesla electric cars to prominence. Following the release of the Roadster and the development of new longer range Tesla cars, we have seen several other companies including Nissan, Daimler and BMW bring electric cars to market. Nevertheless, for all the competition and technical input to electric car design, the weight to range ratio of lithium-ion batteries places practical limits on the utility of electric cars when compared to ICE cars."

From Red Barons's Scientific American report: "As with all of Johnson’s work to date, this result has appeared only in the form of reports and other “grey literature.”
Grey literature is not allowed in the IPCC report because it is considered unreliable. Johnson needs to replicate his work and publish the results in a peer reviewed report. Hardly part of the scientific consensus.

@20 liberator,
That study does not include Methanotroph activity in their CH4 analysis. So their methane analysis was flawed compared to feedlot. But they did report soil sequestration of CO2e resulting as a net negative. So they got that part right at least, even using imported alfalfa hay, which is not needed in HPG, unlike certain other AMPs. Important to note too that the rang of soil sequestration they found was within the 5-20 tonnes CO2e / ha/ yr found elsewhere. Once they finally get the methane cycle right too, the differences will be even more profound.
@Kevin C,
Thanks for the time and effort. Here is more fuel for the fire.
Can Soil Microbes Slow Climate Change?
" Johnson reported a net annual increase of almost 11 metric tons of soil carbon per hectare on his cropland."
Converted to CO2e that is ~ 40 tonnes CO2e/ha/yr. About double the average reported by Jones and 4x what was reported by Teague, but nearly the same as the high outliers. Jones also took the raw results and measured that only 78% was stable humic polymers and I don't see where or if Johnson did that.
It's not HPG, but it does show the biophysical capacity of microorganisms in the soil to sequester high rates of carbon.

Gsmakin @117 ,
thank you for the link to "the blogger's presentation" [ = WUWT blog ] of 22 February 2018.
If you scroll down about halfway on the comments section there, you see an interchange between Nick Stokes and the guy who calls himself "Kenneth Richard" (who is a major propagandist at "No Tricks Zone"). Quite informative. Continue through to the final post, which is by Kristi Silber (who is also one of the handful of commenters worth reading on WUWT).
Gsmakin, I am unsure of your degree of familiarity with WUWT. My take on that blog, is that the usual articles are worth a quick glance (but are typically puerile propaganda spin) and the comments columns are mostly filled by posters who are (A) political extremists somewhere to the right of Genghis Khan, and/or (B) crackpots who maintain that CO2 has negligible effect on terrestrial climate, and/or (C) tinfoil-hat conspiracists.
~ So, please do not waste too much of your valuable time in detailed reading of the articles at WUWT . . . and as for the comments columns, best just to scroll down at high speed, but pausing to read anything by Nick Stokes, Steven Mosher, and Kristi Silber. (NB: up until recent times, the WUWT site allowed commenters to give each other a vote of thumbs-up or thumbs-down. It was highly noticeable, how the above three persons always received a heavy downvote ~ but with that system gone, the other commenters simply express their vitriol verbally . . . when they can spare time from berating the general science community.)
As for Kenneth Richard ~ oh what a blackened conscience he must have, from the persistent way his output is brimful of mendacities, doctorings, and misrepresentations. A propagandist, in the most pejorative sense. (To quote from Nick Stokes on 22 Feb 2019 there : "There is no truth in Kenneth Richard's misrepresentations" )

Regarding "The growth of climate change misinformation in US philanthropy: evidence from natural language processing (open access)"
This certainly demonstrates the power of lobby groups and campaign financing over politicians. I was a little bit interested in some of the research referred to in the article, so I tracked it down, so here are some links to open access articles:

MA Rodger: Yeah, the first bit you quote is a summary of the locations from which the data across all three of the referenced papers was derived (Stein, Yamamoto and Moffa-Sanchez). Maybe I was overly broad.
As to the "opposing arguments" section I'm not here referring to the studies themselves but rather to the blogger's presentation and the manner in which he intends his audience to imbibe it. To quote from said blog:
"Further to NOAA’s claim that Arctic sea ice extent is at its lowest for at least 1500 years, Kenneth Richard highlighted three studies last year that show the claim to be bunkum."
The clear intention is to erode confidence in the NOAA findings by presenting a series of graphs which depict a "present" with much more arctic sea ice than at multiple points in the past (not just the Holocene Thermal Maximum). Presented in that way the author clearly seeks to reverse the alarm that the NOAA graph must surely cause by depicting its cliff face as a little kink in otherwise wildly undulating trend lines.
At least that's the way I saw it.

gsmakin @111,
You say:-
"In total these findings appear to cover the Chukchi Sea, East Siberian Sea and Eastern Labrador Sea and to be fair do seem to detail periods of the last 10k years when these areas had far less ice than today."
The graph set out data from a single location in the Chukchi Sea (73N,166W), the ARA2B-1A bore hole (labelled A1 on the maps set out in the paper). This is a location that was marked in Atlases as being permanently frozen, but not any more.
But note that the paper (Stein et al 2017) does set out that their findings of increased ice in the Chukchi Sea over the last 2ky are reflected by results from elsewhere in the Arctic.
But the assertion @115 which you attribute to "opposing arguments", that "although current ice loss looks huge to us it is actually a mere nothing when looked at over centuries and millenia", such an assertion seems to be saying that the Arctic had entirely ice-free summers during the Holocene Thermal Maximum. This was not so. Arctic summer ice was not greatly different to the situation of the early 21st century and probably more icy that we will be seeing in coming decades.

Daniel Bailey - Those were indeed the findings i was familiar with and i do not doubt them but it's always worth examining the arguments of others to see if they hold any credence and if not, understand their weakness so others don't fall prey to them.
In this case the opposing arguments seem to be that although current ice loss looks huge to us it is actually a mere nothing when looked at over centuries and millenia. There are then displayed a variety of graphs depicting great hillocks from the past to little bumps in the present with a little arrow saying "you are here."
All this can get a bit confusing to a layman such as myself and although I try to educate myself I'm very grateful i can come to a site like this and be able to have my questions answered.
