John Hartz at 05:52 AM on 16 March 2019CO2 is plant food
@ remmons 31:
The NASA article that you reference was published on April 26, 2016. It has been susequently updated by the following article:
Human Activity in China and India Dominates the Greening of Earth, NASA Study Shows, NASA, Feb 11, 2019
The concluding/summary paragraphs of the update article:
The researchers point out that the gain in greenness seen around the world and dominated by India and China does not offset the damage from loss of natural vegetation in tropical regions, such as Brazil and Indonesia. The consequences for sustainability and biodiversity in those ecosystems remain.
Overall, Nemani sees a positive message in the new findings. “Once people realize there’s a problem, they tend to fix it,” he said. “In the 70s and 80s in India and China, the situation around vegetation loss wasn’t good; in the 90s, people realized it; and today things have improved. Humans are incredibly resilient. That’s what we see in the satellite data.”
This research was published online, Feb. 11, 2019, in the journal Nature Sustainability.
The moral of the story: Science is a continuous process.

According to NASA, the earth is greening, and it is 70% due to anthropogenic CO2.

"At the very least we need a semi market based mechanism like carbon taxes or cap and trade"
As a minimum. The main problem with the version of the free market we have, and which got exponentially worse since the international deregulation in the 80s, is that it does not really fit the the parameters for what basic economics says is necessary for a free market to run efficiently and safely - full and open knowledge of all aspects of it for all participants and, importantly, costs of doing business should end up on the accountants' bottom lines.Externalities - the cost of avoiding acid rain, polluted rivers, sickened people, altered climate, degraded land and habitat etc. should be accounted for as a cost of doing business. Carbon taxes would be a big start. With this 'environmental economics', the awesome power of the free market to achieve things and supply goods and services would be unleashed. Those goods and services which were cleaner and greener and/or less damaging would become the same price or less than the 'dirty versions' and the great mass of the public would vote with their wallets. 'Bad' products, and the corporations that made them would be less profitable, investment in them would wither away.
Doing it this way means virtually no environmental legislation, which so many kickback against, would be required

Neoliberalism.
Neoliberalism has huge implications for the climate issue. Some quick background. According to Wikipedia : "Neoliberalism or neo-liberalism[1] is the 20th-century resurgence of 19th-century ideas associated with laissez-faire economic liberalism and free market capitalism.[2]:7[3] Those ideas include economic liberalization policies such as privatization, austerity, deregulation, free trade[4] and reductions in government spending in order to increase the role of the private sector in the economy and society.[12] .....Modern advocates of free market policies avoid the term "neoliberal"[20] and some scholars have described the term as meaning different things to different people[21][22] as neoliberalism "mutated" into geopolitically distinct hybrids as it travelled around the world.[5] As such, neoliberalism shares many attributes with other concepts that have contested meanings, including democracy.[23]"
It's obvious to me that neoliberalism is a reaction against keynsian policies of the 1970's of protectionist trade and extensive state ownership going into industry and banking.
Free trade is pretty much embraced by almost everyone in developed countries, left and right alike. The battle ground is over how far privatisation should go into core infrastructure and how much we should deregulate. I think only the fanatics and the irrational would think everything should be privatised and deregulated. This seems as ridiculous and irrational as communists thinking the state should run everything. Neoliberalism is tiresome like all ideologies.
It's particularly frustrating because environmental problems are hard to solve with purely market based mechanism's such as "self regulation" (does that ever actually work?). At the very least we need a semi market based mechanism like carbon taxes or cap and trade (I prefer the former fwiw its more transparent).

Eclectic,
Rereading your comment @53, I understand that you may have clarified the goal posts regarding your initial comment @45 (which only asked for Prominent names incorrectly used to gain credibility). You may be seeking 'very frequently used Prominent names'.
I agree that Darwin is not frequently used, though there actually are cases where Darwin has been abused by climate science denial promoters like Monckton (as the DeSmogBlog item I provided a link to showed).
What I see related to Darwin that is frequently abused (by the likes of Monckton) are the many suggestions that it is acceptable for current day people to not give up some of their developed perceptions of prosperity and comfort just to reduce the harm done to future generations because 'those future generations will be able to adapt, the incorrect Darwin link'.
Examples of this incorrect link to Darwin are the economic claims that the artificial developed perceptions of wealth, prosperity, or reduction of poverty that are the result of the unsustainable and harmful burning of fossil fuels will somehow be sustained into the future (perceived positive results of unsustainable harmful behaviour are very unlikely to be sustained positives in the future).
Similarly incorrect are the related claims that the perceptions of loss of status by portions of the current generation if 'they had to adapt' to the reality of the unacceptability of harming the future generations must over-rule the fundamental understanding of the need to minimize the required 'adaptation to the harmful future consequences of the current generation dragging its feet about correcting what has developed (foot dragging because they - collectively - do not want to correct their incorrectly developed perceptions, they want to allow everyone to continue pursuing 'their happiness any way they have developed a liking for'.
Efforts to improve the awareness, understanding and acceptance of climate science cannot be separated from the related need for increased acceptance of the need to achieve and improve on all of the Sustainable Development Goals (not just the minimization of climate change harm), which cannot be separated from the related reality that some people will have to lose developed perceptions of status relative to others (not just the coal barons). That is a lot of incorrect developed popularity and profitability to over-come, but the future of humanity needs the corrections to be done, and be done by the current generation because they are the only ones doing anything and everything, including creating the future for humanity through their actions (or lack of correction).

Every example where mankind has destroyed an environment, from the ocean to the mountains, and then completely left it alone...I mean completely, those environments eventually recover in the most amazing ways. Granted this example does not happen often but I know of many.

I've just posted this on the video comments on YouTube.
"This is a lovely vision of a version of utopia but just 'fixing' climate change on its own is a gigantic task on its own, let alone all the other things on this wish list. It's true that some of what is planned to mitigate and reduce future emissions could help some of the desired effects to come about, but I do see a problem. I'm a seasoned climate science denialism fighter and I can tell you that the most sophisticated and effective propaganda these days comes not from fossil fuel interests, as many environmentalists still believe, but from those who are wedded to far right-wing laissez-faire freemarket ideologies, and those who espouse simplistic neo-liberal economics. Much of the motivation behind a lot of high profile denialism comes from those who believe so strongly in their political view of the world that they regard it as justified to spread miseading and deceptive denialist propaganda, that they secretly know (I have come to this conclusion after many years of engaging with these types) has been debunked a thousand times. They do this because it has a proven ability to sway the minds of the voting layman public. The propagandists have a deep seated antipathy to, and wish to sabotage, what they see as far left wing ideology being 'slipped in' by the back door under the impetus to change things that climate science gives us. In short, they believe that many of those with environmental climate related concerns are 'watermelons' - green on the outside, red on the inside... Couple this with the 3% minority of climate scientists whose work suggests either that the climate change we see is not really down to us or that climate sensitivity is much lower than the IPCC figure so that means the eventual warming won't be that bad and the benefits may outweigh the problems, and they have at least some scientific justification, even though it is limited in size and overwhelmed by the mainstream view, for 'taking a gamble' to preserve the status quo." -

@nigelj, this is a total illusion as long as overpopulation, greediness and the hunger for money are not stopped. Because the driving force of our economy is making money, gathering assets and creating so-called wealth all at the expense of nature and natural habitats. Even when it becomes so obvious that the already irreparable damage created by our behaviour threatens our existence, people will even try to profit from the self induced catastrophes until our artificial world collapses totally by itself. There is almost no chance of escape.

Daniel Bailey at 09:56 AM on 14 March 2019Greenland is gaining ice
Surface melt and snowfall mass balance are not the sum of the total mass balance equation by far. Because calving and discharge from the margins are not factored into that.
Per ther DMI:
And
Which brings it into good agreement with NASA:
"Data from NASA's GRACE satellites show that the land ice sheets in both Antarctica (upper chart) and Greenland (lower) have been losing mass since 2002. Both ice sheets have seen an acceleration of ice mass loss since 2009. (Source: GRACE satellite data)
Please note that the most recent data are from June 2017, when the GRACE mission concluded science operations. Users can expect new data from GRACE’s successor mission, GRACE Follow-On, in the summer of 2019."

Molsen at 09:09 AM on 14 March 2019Greenland is gaining ice
The graph supports the article being updated. The mass loss since 2012 has been much less than what occurred from 2006-2012 — i.e., the mass loss since 2012 is probably one-quarter what is was in the preceding six years.
However, the second paragraph of this entry, with its use of the phrase "drastically increased since the year 2000" misses that entirely.
So, the end of the second paragraph should have the following added to be accurate and fair:
"but the rate of decrease has slowed remarkably since 2012 for reasons that are unknown. This declining rate of mass loss has gone unacknowledged by the media and climate scientists. On the contrary, the media (at least) have reported that the opposite is happening. At this point, that is not the case."
A fair statement?

I wouldn't be surpised if one reason Darwin's name rarely comes up in the denialati's musings is because the climate pseudo-skeptic group is probably strongly overlapping the evolution-denying group. The last thing they would want to do is promote Darwin as the kind of scientist they admire.

dmyerson at 07:00 AM on 14 March 2019What's in the Green New Deal? Four key issues to understand
Scaddenp - "stands no chance of passage in the Senate over the next two years. But Mother Nature does not wait on our political calendar, and neither can we" - that would seem to suggest that something else of value was likely to pass the Senate and become law in the next two years. What would that be? As far as I can see, it is the GND that has forced at least some Republicans to address the issue. My Republican rep chaired the House emergy committee till last Nov and held no hearings on climate change in the years he was chair, nor did anything regarding climate change pass. Now he says he has a better policy than GND, which mostly seems to be cutting down more forests so they won't burn. He ignored the issue till the GND showed up. Whatever one thinks of the policies in the GND, it appears to me to be forceing the discussion, and moving that discussion from whether there is warming caused by humans, to what we should do about it.

You should read the Polar Portal Season Report for 2018, published in November 2018, by DMI. It notes some positive things, such as Greenland's glaciers losing only a minor amount of area in the last six years.
That's fantastic news. Take a look at the helpful graph DMI provides on page 5. Will the trend continue this year? I dunno, but it's interesting the last six years have gone unnoticed by the MSM, etc.

I want a world that understands that the economy has to be on an environmentally sustainable footing for business to survive and prosper long term, and where clean food, univeral healthcare and social security are assured. I also want to create a world that maximises individual freedom, the freedom to be different, and which maximises private enterprise and private ownership.
A world that balances the rights of the individual with the rights of the community. A world that respects both liberal and sensible conservative concerns, because if it doesn't nobody will listen and no legislation will stick.....
Oh and a world without confirmation bias, dunning kruger, motivated reasoning and logical fallacies...

Anyone wanting to be a Helpful Skeptic improving awareness and understanding of climate science needs to do what Feynman learned to do early in his career 'formally publish their alternative understanding in the Peer Reviewed Publication process'.
Of course, if incorrectly influencing public opinion is the actual objective then 'other means - like political misleading claim-making - would more effectively achieve that end'.

Eclectic @53,
I believe that a list of names that are 'used incorrectly' by political misleading marketers attempting to delay improved awareness and understanding of climate science is 'on-topic' for this OP.
My comment @52 included aspects of circumstance for people named in vain that are actually inconsistent with the political misleading marketers who want to claim to be Skeptics just like those they 'name-drop incorrectly'.
I would encourage you to reconsider your understanding of the motives of the anti-climate science marketers. Though some religiously indoctrinated people can be easy targets for politically motivated misleading marketing promotion of climate science denial, the people creating the misleading marketing are not likely to be attempting to defend religious leadership. And they could abuse Darwin by making the claim that 'people who would believe the thinking of Darwin should understand the unacceptability of being dismissive of alternative beliefs'.
My comment @40 presents a likely motive for the development of political misleading marketing against the improvement of awareness and understanding of climate science. And my comment @52 suggests that the development of misleading marketers against climate science was the motivation for developing SkS and the Denial101x MOOC.
Potentially off-topic, I would add that although people agree that it is important to reduce the harm done by the burning of fossil fuels, many of them would not support action that they perceive as potentially negatively affecting them ('their' perception being the key point). And that perception does not depend on religious views.
The misleading marketing efforts to keep people inclined to oppose actions that would reduce the harm done by burning fossil fuels abuse that tendency. They create messaging to tempt people to resist correcting personally beneficial behaviour that is actually understandably harmful. That is potentially why in the USA, and many other places, the majority of the population will say they accept climate science and would support climate action but the majority also continue to support leaders who oppose or want to severely limit such actions. Some people allow their personal interest to over-rule their ability to understand the need to correct their behaviour, particularly to change who they vote for, to stop harming the future of humanity and help develop sustainable improvements.

Philippe Chantreau at 04:14 AM on 14 March 2019Next self-paced run of Denial101x starts on March 5
I agree with Eclectic. Feynman is a frequent mention by deniers, although they fail to see how different he was than anyone in their "camp." Feynman was very wary of any kind of certainty or emotional attachment to ideas. He argued that any good scientist is his (her) own worst enemy, and that one should always scrutinize his results, be open to revision or accept that a lot of work was spent on identifying something that was wrong or a dead end. The way that Spencer/Christy handled themselves with the successive corrections required to their work, which were identified and applied by others falls far from these standards, and yet these 2 are among the few legitimate scientists speaking against the consensus; interestingly, their own scientific work that has been subjected to proper scruntiny does not even support their public satements.
Skepticism is the part of Feynman they like, but it requires them to imply that adequate scrutiny and the corresponding scientific approach has not been maintained for literaly thousands of papers to reach the current state of climate science. They try to do that and quickly show that they're full of it. The other important aspect is that Feynman actually was a brilliant physicist, who contributed to the current state of that science. Not one of the very few legitimate scientists speaking against the consensus has a comparable dimension.
Finally, for all his whining against labeling deniers with a pyschological disorder, Prometheus shows some rather shining exmaple of it. He mentions how Feynman denounced the pressures applied by some of the NASA upper management to the whole program, to produce results and launch flights even when risk existed that the real scientists and engineers had identified. This is a clear example of people in position of power, with a strong political component to their role, overriding the judgement of those who actually know what they're talking about. Prometheus would not comment on successive administrations imposing silence on researchers, attempting to suppress or bury results, upper management watering down reports, etc. The most grotesque of all may be the Carolina's legislature attempt to ban the words "sea level rise acceleration." All this happened repeatedly under the Bush administration and has reached unprecedented levels in the current one. It is a blatant example of politics interfering with science, exactly what Prometheus claimed to be wary of, but somehow, that's not where his concerns were. The high quality skeptics he wanted to defend seem to be in ever dwindling supply...

What about Cretaceous or Paleogenic Earth? The CO2 levels then are more comparable to where we are headed, and geological and biological factors are likely more similar.

OPOF @52 ,
thank you for your suggestion of "Darwin" as an addition to the denialists' favorite allusions [addition to my list: Galileo / Einstein / Feynman / Popper].
But in a Cavalier manner, I will reject "Darwin". Yes, he was seen as a contrarian during his early years, as were the scientists Galileo and Einstein. Yet, anecdotally, I haven't ever noticed Darwin's case being used by denialists ~ usually they wish to "wrap themselves in the flag" of famous scientists who were initially ridiculed but were later glorified as being very right. (And probably there's a goodly percentage of climate-denialists who are also evolution-denialists . . . as well as being religious fundamentalists who cling to the biblical belief that God will surely intervene to protect the Earth from major degradation. So Darwin is persona non grata for them.) Galileo and Einstein fit their bill, and the mention of those names "proves" that History will eventually vindicate the "contrarian" climate-denialists.
The case of Feynman is somewhat different, he seems to be alluded to as a brilliant scientist and prominent espouser of skepticism. The denialists fail to appreciate that he was a true skeptic . . . while they themselves are faux-skeptics. But they like to imply they are modern-day Feynmans.
Popper, though not really classified as a scientist, gets some mentions from denialists, because they like his suggestion of the necessity of "falsifiability" (as the absolute criterion for genuine "science"). They wish to wrap themselves in his flag, too. Popper was partly wrong about "falsifiability" [IMO ~ but I don't wish to spend time arguing the point, here] but denialists wish to selectively use falsifiability as a stumbling-block for climate science.
Apologies for my lengthy post, and it is wandering off-topic. But denialism itself is the topic here ~ and I have always found the introduction of some of the above four names, to be a useful raiser of the Red Flag of Suspicion that a poster is engaged in intellectually-dishonest arguments and/or rhetoric. A handy short-cut for the reader.

nigelj at 12:55 PM on 13 March 2019The temperature evolution after 2016 suggests hotter future
It seems to me claims its cooling again (insert 1998, 2018, whatever) are a form of stalling for time, just like the claim I have often heard "climate is so complicated so we need more research before cutting emissions". Stalling for time is a common denialist rhetorical tactic, and could be included in courses on denial 101x (if it isn't already).

-
One Planet Only Forever at 12:25 PM on 13 March 2019The temperature evolution after 2016 suggests hotter future
Making a claim that takes 'time to be proven to be incorrect' is a common tactic of the climate science deniers. They are not being skeptical of the science. They are politically trying to delay the improvement of awareness and understanding among the general population regarding how incorrect and harmful the people they are voting to support actually are.
A similar tactic will be used when the most recent decade of data is added to the global surface temperature escalator. The claim will be made that the economic harm of the correction is now so big (because the economy was incorrectly increased in the wrong direction and the needed correction is more significant and needed in a shorter time frame). Surely it would be prudent and pragmatic to wait until one more decade of temperature data is actually gathered. We really need to be very sure about this - don't we?
The people who have developed undeserved perceptions of superiority (wealth or power) by benefiting from the burning of fossil fuels, particularly through the past 30 years when it was undeniable that the activity needed to be globally curtailed, fear the coming correction will actually negatively affect them and their 'status relative to others' (as it should - they should particularly lose any increased perceptions of status obtained through the past 30 years).

Basically, the link goes to an image that is 200% of the OP scale if the OP is being viewed at 100% zoom (no zoom).

Ken in Oz at 08:55 AM on 13 March 2019Wallace Broecker: Scientists memorialize a titan of climate science
The Broecker led 1975 NAS/NSC report "Understanding Climatic Change; a Program for Action" was an important one that gets less mention than I think it should. As a counter to "scientists predicted cooling in the 1970's" arguments it is priceless - making it clear that the 70's science did not have sufficient quantitative understanding of climate processes to make such predictions and proposing a science program to turn that around. Which ultimately led to a soundly based conclusion that we don't have to worry about global cooling - although learning exactly why we need not worry about imminent global cooling was not nearly so reassuring as people had hoped. The government responses more closely followed the advice within that report - the current mainstream best available knowledge - and not the ice age alarmism that was principally a media creation. (Building on hype begun by existing nuclear winter stories?)
Broecker's 1975 report also made clear that understanding how and to what extent human activities might affect the climate had already been a long running, if not yet so high priority, goal within existing science programs. Science programs that had, at that point, cross-partisan support.

Eclectic@45
I suggest adding Darwin to your list.
Einstein and Darwin introduced very good new explanations of what was going on. Their developed thoughts differed from, or went beyond, the awareness and understanding that had been developed at their time. Unlike the claims made by politically motivated deniers of climate science, their thoughts were consistent with all of the already developed awareness, information and observations.
Darwin, in particular, faced opposition from opinionated people whose developed perceptions of status were challenged by the improved awareness and understanding that Darwin presented. They were unable to reasonably argue in support of their preferred opinions. But they were powerfully motivated to not correct their awareness and understanding (to maintain perceptions of status, including maintaining the status quo). And those challenged by Darwin's improvement of understanding tried very hard, and still try today, to delay the improvement of awareness and understanding in the general population (I will come back to this).
Feynman's case is a little different. Initially, he was unable to get his ideas across in a brief conference presentation to his peers (he faced a lack of acceptance by the established scientific community at that time based on that presentation). However, when he formally published his ideas they became generally understood, accepted, referred to and worked with by his peers (legitimate climate science skeptics would present their thoughts for consideration through the Peer Reviewed Publication process - and attempts to publish in incorrectly peer reviewed publications are political acts, not the pursuit of improved scientific understanding).
Galileo actually had the correct independently verifiable basis for the awareness and understanding that he presented. But his case is a clearer example of presenting a more correct awareness and understanding that challenged the legitimacy of developed perceptions of status of 'the socioeconomic-political leadership of his time and place' (Similar to Darwin, but leadership in Darwin's time included people whose status was not significantly challenged by the new awareness and understanding).
Contrary to the claims made-up by political deniers of climate science (as differentiated from science skeptics who would address their skepticism through the Peer Reviewed Publication process), the climate science community is the party that is most 'like Galileo'. They are collectively developing a more correct awareness and understanding that is challenging the legitimacy of developed perceptions of status of 'the currently developed socioeconomic-political leadership'.
Applying Abductive Reasoning (pursuing the likely best explanation for what can be observed to be happening when what is being observed cannot be investigated by controlled repeatable experiments), Prometheus has very likely developed a personal preference for claims that cannot be reasonably substantiated - an all too common nonsensical and harmfully incorrect result of political marketing actions by deliberately misleading deniers (likely for the reasons I suggested in my comment @40).
Philippe Chantreau's simple request of Prometheus (that could be perceived as a confrontational challenge if the request cannot be responded to reasonably), to present a single example of "relavent arguements made by the skeptics that has changed the perspective of climate change science and advocates alike", has led to a stream of commenting that exposes that Prometheus is very likely acting politically in an effort to impede their own improvement of awareness and understanding regarding climate science (also, potentially hoping to reduce how much the politically incorrect climate science denial efforts they have a developed preference for are publicly challenged and confronted on SkS).
The motivation for the helpful development of websites like SkS is likely the powerful political misleading marketing efforts to resist the corrections of developed perceptions of status that the acceptance of climate science rationally/naturally can be understood to lead to (corrections of perceptions of wealth or influence developed due to the harmful and unsustainable, and incorrectly popular and profitable, burning of fossil fuels). And the diversity of political misinformation marketing tactics abused by the climate science denial industry are likely the motivation for the helpful development of the Denial101x MOOC.
Improving awareness and understanding and the application of that knowledge to help develop sustainable improvements for a robust diversity of humanity thriving in ways that fit into the robust diversity of life on this amazing planet clearly needs all of the likes of SkS and the Denial101x MOOC that can be developed.

Good question Postkey. I don't recall anyone ever really be that specific. No quote is provided. And it is, in fact, off topic. This thread is about Anthony Watts' and others assertion that the consensus is based on only one paper, and that said paper was flawed enough to invalidate the results. As usual, Watts is full of it.

Great post and comments. Looking at Evan’s plot @1, one could say “ok denialists, let’s ignore El Ninõ years”. What do we have left, a plot of annual temperatures, complete with annual variations, that have warmed about 1°C since 1970.

The politicians only get to be politicians if they are elected, regardless of how much money they raise. If we stop electing climate-change deniers, we might start making progress.

SirCharles@6 Interesting graph. It would require 0.5C of warming in the 2020's, vs the 0.2C/decade of warming that we've typically experienced. Anything is possible, but I've struggled with this kind of messaging. I decided to base my projections on the Keeling Curve, because if you fit 60 years of CO2 data you get a quadratic function that fits the data with a fitting parameter of 0.99 (1.0 represents a perfect fit). We are trying to motivate action based on the most solid evidence we have, and I think the Keeling curve comes about as close as we can to solid data that we can use to confidently project what will happen if we don't take drastic action.
I'm not suggesting your curve is wrong. I am simply suggesting that the Keeling curve on its own is scary enough to motivate action, and it is based on 60 years of solid evidence of how the entire system (humans + nature) has been responding.
The gray data points that are mushed together to form a thick, gray line from 1958 to 2018 is the data for the Keeling curve. The thin curve on the left shows rising CO2 projected into the future based on a fit of the 60-year Keeling curve and indicates when we are projected to lock in particular temperature anomalies based on a climate sensitivity of 3C/doubling CO2. The curve on the right projects when we will realize that temperature anomaly, based on a 30-year time lag between commitment and realization.

And to whoever asked, a positive feedback loop isn't necessarily runaway. It can give diminishing returns, due to many other factors at play. Which would be why we don't see runaway heating from water vapour

Which also addresses Mizimi's comment about how animals make a bigger difference in terms of heat. I havent confirmed anything on that study, but methane doesn't last in the air for the same amount of time CO2 does, it's significantly shorter. Thus it is already in a stable equilibrium. As more methane is put In, the old methane is coming out of the system at the same time. Its not the same for CO2 as we haven't been putting it in the system at a stable rate for long enough that the oldest will start coming out of the system.

I'll also add that even if water vapour wasn't a positive feedback loop, it doesn't matter if water vapour keeps in a huge amount of heat compared to CO2, That doesn't somehow make the CO2 induced warming insignificant. Such a claim is trying to trick you by warping your perspective.

"The problem is when people use the study and try to state 97% believe +50% of warming is CO2 and that its dangerous (President Obama and the authors)."
Are there 'people' that use the study and try to state 97% believe +50% of warming is CO2 and that its dangerous (President Obama and the authors)."

Thanks all! Nigelj, to me the graphs open up clearly larger, and for example the texts on them are easy to read, so I suggest it might have to do something with your browser. If others have problems with graphs, let me know.

BOb, the trouble is, that pseudo-skeptics and misinformers are doing exactly the same thing.

Yes, well-done Ari.
As for the "no warming since..." gambit, I mentioned this previous SkS comment a couple of weeks ago over at Tamino's, but it is worth pointing to it again. From July 2016:

Daniel Bailey at 08:31 AM on 12 March 201997% consensus on human-caused global warming has been disproven
"There is no significant disagreement on the main points in the scientific community"
Indeed, the evidence for AGW is as robust as for Auschwitz.
Abundant attribution studies show that pretty much all of the observed warming since the 1950s is from human activities, primarily via the human burning of fossil fuels. This is a more appropriate thread for you to read on that, including the comments.

"We" go with what the published science supports. The ECS is estimated at around 3 and there is no way to realize that over such a short time period. If you want to argue for low sensitivity, then do so here or here (after first reading the article and associated papers)
The point of the consensus study is to show that a scientific consensus exists and that it is strong. What would be your alternative basis for policy in any field? I find it hard to believe you would advocate government policy follow the extreme fringe in say medicine, building standards, etc. The consensus might be wrong even if very strong but this is rare and no basis for policy.
If you believe part of the warming is natural, (and hopefully you also believe in conservation of energy), then perhaps you might indicate which natural source do think is providing the extra energy?
