Tom Curtis at 15:19 PM on 24 June 2017Exxon, Stephen Hawking, greens, and Reagan’s advisors agree on a carbon tax
Ogemaniac @1, first, carbon taxes are normally designed to tax CO2eq emissions, and consequently do not ignore emissions other than CO2. Further, given a sufficiently large carbon tax, industry will itself pay for the necessary infrastructure, etc. At least it will if given sufficient time to adapt. The major problem with a carbon tax, other coordination between separate economies, is that as the time span to convert to a carbon free economy contracts, carbon taxes become more and more inefficient. At some point they become less efficient than regulations, but it is certainly not clear that we are at that point yet.

"Secondly I would question whether a carbon tax should be completely revenue neutral...."
In my humble opinion, having a scrupulously, exactly and demonstrably revenue neutral carbon tax is the one way it might suceed. Otherwise, the voter's already slim trust in Lucy...mm, goverment fixes... will go 'poof' and any future proposals from the same quarter will be met with rage. It's already at this point with many taxes; in the USA we have a "temporary" tax on telephone services which was to pay for the Vietnam war. That was about 50 years ago, the tax is still collected. Same for 'temporary' state tax hikes, they are all but permanent.
As for renewables, when the public's income tax is lower they have more to spend, sales of goods increases so business has more ability to invest. At least some will use that for electric delivery trucks, solar hot water, perhaps solar electric, etc. After low-carbon replacements demonstrate success - IF they succeed - then they'll be adopted in bulk. Something's better than nothing.
Personally, I think that as long as the world has 7 billion people, nearly all of whom want refrigeration, TV, cars and meat, we're going to have a degraded environment. You're not going to change the fact that 99% of humanity wants more, not less. If we got to 3 billion instead of 7, this and other issues could be tackled with ease. This is politically a non-starter, of course.

Ogemaniac @ 1, yes a revenue neutral carbon tax is clearly insufficient as a stand alone scheme to fight climate change. But it doesn't have to be a stand alone scheme.
Firstly a similar tax scheme could be applied to methane emissions in theory, as a tax on animal products, or you could deal with methane emissions in other ways.
Secondly I would question whether a carbon tax should be completely revenue neutral. Part of the money could be given back to the public directly, or with income tax cuts, part could go into things like electric cars, and part could go into the administration costs of a carbon tax scheme anyway.
Thirdly and alternatively have a revenue neutral carbon tax, and the government could just subsidise renewable energy. This is not ideologically incompatible. There are also cases where subsidies make economic sense, because of recognised market failures.
I think we are faced with trying to develop the best possible overall package of measures that is ideologically acceptable but also practical, and we won't ever address all of these perfectly, but can do a reasonable job overall. We probably need a combination of taxes, some mild regulation and subsidies. There are no perfect ideologically pure and pain free options, but a carbon tax of some sort combined with measures to address methane etc and rebewable energy seems the best overall.

One Planet Only Forever at 09:06 AM on 24 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
nigelj@8,
I am not convinced that media have to state a climate science myth. The reports should simply present a clear and fairly complete understanding of the science and leave it to the recipient to understand how misleading the myth messages are.
What should happen is the media that fails to present Good Reasons for their reporting will be more clearly understood to be providing Poor Excuses.
That does not mean that the Poor Excuses will not be popular. I have mentioned many times that behaving less acceptably affords the Bad Behavers a competitive advantage as long as they can get away with it.
The failure of leaders in business and government to effectively block the pursuits of Winning by the less acceptable behavers, thwarting their attempts until they learn to change their minds, is a failure of the society they are members of no matter what perceptions of prosperity get away with being temporarily created or prolonged. In fact the larger the development in the wrong direction (away from Good Objectives like the sustainable development goals), the bigger the inevitable correction will be. That applies to individuals, businesses, and nations.
Trump told no lie when he said that doing responsible changes to correct for past incorrect development regarding climate impacts will be harder on the callous greedy in the USA and many other nations. But they have no one to blame but themselves and those among their predecessors who were just like them.

TC @7, yes I realise all that about the movie! I'm sure most people would understand things can't happen that fast or involving super storms taking up half the plant. I was just trying to say rapid change of some sort is possible. I should have been clearer.
Abrupt climate change on wikipedia is an easy to read account of past periods for lay people, and documents periods of several degrees of cooling or warming in a matter of just a few years, and changes in weather systems although not at the speed or scale of the movie. That would still be bad enough for humanity to adapt to on global or even regional scales.
However no doubt the teflon coated president would somehow escape a cooling event, tucked away down in mar a lago.

nigelj at 07:53 AM on 24 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
OPOF @7, what you say makes total sense if you are talking to a friend, or responding on a website. No need to restate the myth, so you just respond on whats really happening with temperatures (and this can also be a valid response to numerous myths)
I think the issue being described above is more relating to the media. It's hard for the media to respond to the latest myth doing the rounds in society, without actually stating what it is, and the logical place is to put the myth as the top of discussion. Avoiding being specific about the myth or burying it in the text is confusing for me.
However I agree about satellite data. A couple of additional things occur to me. If you are just a typical person and not a science expert and look at the UAH satellite data on Roy Spencers website, or over at RSS, the graph looks kind of flat compared to the surface data. This is partly because the vertical scale is simply a bit different I think. When you see the satellite data together with surface data on the same graph, there is much less difference. Of course the satellite data doesnt show as much warming since about 2005, but when seen together with the surface data even that difference is not as huge as it seems.
And the satellite data doesn't measure temperature directly. It extracts temperatures by measuring changes in the molecules that make up the atmosphere, and this is not as reliable as simple surface thermometer readings.
As you undoubtably know satellites also do not actually measure surface temperatures where we live, only the middle of the troposphere. But how many other people realise this?

nigelj at 07:12 AM on 24 June 2017Exxon, Stephen Hawking, greens, and Reagan’s advisors agree on a carbon tax
Carbon taxes have worked quite well in British Columbia as below. They have reduced emissions and fossil fuel use, and ironically because it was set up as revenue neutral, people now have low income tax rates. I wouldn't claim its all perfect, but it is proof of basic viability and potential, and shows the predicted negative problems haven't happened.
www.theglobeandmail.com/opinion/the-insidious-truth-about-bcs-carbon-tax-it-works/article19512237/
Not only do carbon taxes incentivise people to reduce carbon use, they provide an income stream that can be given back to the public, or used to subsidise electric cars, or subsidise renewable energy or some combination of these. This seems to make total sense to me in a practical sense.
In my opinion, carbon taxes are transparent and upfront costs with a clear price on carbon underpinning the concept, where cap and trade schemes are harder to comprehend and appear less upfront. A revenue neutral tax overcomes most of the ideological criticisms directed at taxation. We know from history and economic analysis that taxes can influence rates of consumption of products.
Carbon taxes are flexible, and can be combined with government regulation regarding large emitters.
But to be effective carbon taxes do need to set quite a high price on carbon that will raise petrol prices very significantly, so its important that renewable energy alternatives and electric cars and hybrids are made attractive options. The two things must be combined.
Alternatively you can force companies to keep fossil fuels in the ground by simple government regulation. This is simple and almost ideal, but it's unlikely to win industry, political, or public approval and may be perceived as harsh and excessive use of state power. It would be hard on consumers as well.
The other alternative is an emissions trading scheme, sometimes called cap and trade. This is one of those mechanisms that makes total sense confined to a textbook, but I think it has problems when implemented in the real world. For example the scheme in Europe has been only minimally effective, and the whole scheme looks easy for governments and participants to manipulate and rort to me, because of its inherent nature. The public in my country are suspicious of the scheme as it looks like crony capitalism. This may be unfair, but the perception is there.
Cap and trade also looks suspiciously like a neoliberal free market dream, artfully structured to look good, but designed to achieve precisely nothing, but so complex that all this becomes well hidden. Poor results in Europe seem to bear this out.
Carbon taxes seem the best alternative overall.

Ogemaniac at 06:16 AM on 24 June 2017Exxon, Stephen Hawking, greens, and Reagan’s advisors agree on a carbon tax
There are two major problems with a revenue-neutral carbon tax
1: It only addresses about half the problem, as other climate-related pollutants are ignored and substantial amounts of carbon emissions come from non-point-sources such as land use, animal husbandry, or forestry practices that cannot be addressed easily by a carbon tax.
2: The government will need tens of billions of dollars a year if not more to pay for the related infrastructure, R&D, enforcement, and regulations that will be necessary to tackle this problem. Where would this come from, if not the carbon tax?
Such a plan could be a devil's bargain, where by tackling one half the problem, we make the other half unsolvable.

One Planet Only Forever at 01:36 AM on 24 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
When dealing with temperature 'misclaims', I do not have to restate any of the myths. I start with the values for CO2 in the atmosphere continuing to rise rapidly. The NOAA movie is a presentation of data I refer people to because the site includes lots of related information (and some people seem to "Switch Off" if I refer to SkS information).
I state that when you look at the full set of temperature data from any source you can clearly see how much the values bounce in the short term but you can clearly see that the temperature has been increasing. I add that the satellite data starts in the late 1970s, not the late 1990s.
The SkS Temperature Trends tool is handy for seeing the full set of data from several sources (however, some people seem to instantly distrust anything directly from SkS - a testament to the value of this website, but also backfire trigger).
For those willing to use the SkS Temparture Trend tool to compare surface and satellite data I encourage them to set the years from 1978 to 2018. They can see for themselves how the satellite data for the Lower Troposphere (TLT) shows a temperature trend similar to the surface data.
I also try to add that the satellite data is not the temperature at the bottom of the accumulated impact of all the CO2 in the atmosphere (sometimes that leads to an opportunity to present more details).
However, it is unfortunate that there are different baselines for each data set. The difference between the approximate 12 month averages of the non-Satellite data at the start of the 1978 to 2018 plots is from +0.7C for GISTEMP to -1.4C for NOAA. And the satellite values start with 12 month averages of -1C for RSS to -2.1C for UAHv6.0. Those ranges are more than the total increase of the average surface temperature since the late 1800s.
I try to explain that the trend is what is important. But some people focus on the different temperature values, even claiming that the UAH satellite data being so much lower than the surface temperature data proves that the surface temperature data has been Fudged. When I try to explain the different baselines I quickly find out if the person I am dealing with is genuinely interested in better understanding the issue.
Those complexities of properly understanding this issue make it prone to easy abuse by very smart people who deliberately want it to be misunderstood. Those smart deliberate trouble-makers can easily become popular by helping to create effective Poor Excuses for undeserving pursuers of more perssonal benefit any way they can get away with.
The real problem is not the way that climate science is legitimately communicated. The real problem is the failure of leaders (winners) in business and government to deal with those type of undeserving people before they can achieve signficant success. Once enough of those type of people get away with becoming a significant portion of the Winners it can be very difficult to Correct the situation because Those undeserving Winners can and do Band Together to Defend and Excuse each other's different unacceptability.

I would like to propose another consensus. Let us all agree to stop using the term "believe" in and around Climate Change.
Nobody gets to decide if they believe or don't believe in CC. By using the term "believe" people think they need to choose a side like all other belief systems.
You either "understand" or don't understand" Climate Change.

ubrew12 at 22:33 PM on 23 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
This is useful information. There's an almost overwhelming human desire to correct someone who says "There's been no global warming in 20 years". You want to show the many ways this person has been fooled (cherry-picking start dates, cherry-picking temperature surveys, missing the ocean-forest for the atmosphere-trees, etc). Instead you end up reinforcing the myth. The problem is the brazen statement of the myth in the first place immediately places you on the defensive. The fossil fuel companies know that the best defense is a strong offense.
A better response: "Global warming is indicated in the vast majority of surface temperature records, for all time scales, 15, 20, 25, 100 years, and for both ocean and atmosphere."

nigelj @6, the day after tomorrow gets the science almost completely wrong in every way. You might get rapid cooling with an AMOC shutdown, but not a turn around in days. Nor would you get supercells so large and so intence that they are effective vacuums in the eye. Nor, with rapid cooling, would you get snowfall sufficient to bury multistory buildings within a matter of weeks (cold water equals low precipitation), nor a sudden seal level rise (in a matter of days) from current to sufficient to float a ship through NY streets.
And last, and worst of all, what happened to that wall between the US and Mexico ;)

TC @5, that's interesting. There have certainly been some short and quite intense cooling and warming periods, so the day after tomorrow is not quite as out theres as it seems. The current rapid arctic warming seems to fit the definitions of abrupt regional climate change.
An analogy for abrupt climate change might be an earthquake.

Simple messages are indeed powerful. I mean short sentences, and short, clear, concise explanations.
Of course this is not appropriate for dedictated enthusiasts, but it works for certain target audiences. This website gets it, by having different levels of explanation, but sometimes the beginners explanation is still quite complex.
Remember most people are busy people,and dont have the time to read masses of stuff, and others have short attention spans.
Trump is most definitely not to my preference in presidents, but he undertands certain aspects of communication like simplicity, although he probably takes it a bit far at times to the level of a child. But you know what I mean, he does have certain communication skills of a sort, and knows his target audience (say no more).
Most science issues revolve around causation and correlation. Most climate science myths can probably be condensed to a brief couple of sentences on both these elements. It's important to cover both, and get the point across on these elements, and not lost in endless detail, unless you are writing or discussing with someone educated, and with the time and interest to take in detail.

Tom Curtis at 15:33 PM on 23 June 2017New Video: John Cook and the 97 Percent
nigelj @4, from Alley et al (2003)
"“Technically, an abrupt climate change occurs when the climate system is forced to cross some threshold, triggering a transition to a new state at a rate determined by the climate system itself and faster than the cause” (2, p. 14). Even a slow forcing can trigger an abrupt change, and the forcing may be chaotic and thus undetectably small. For human concerns, attention is especially focused on persistent changes that affect sub-continental or larger regions, and for which ecosystems and economies are unprepared or are incapable of adapting."
Reference 2, from which the first sentence appears to be quoted, is the NAS report on abrupt climate change.
The classic case of abrupt climate change is the Younger Dryas, which in Greenland saw a change in precipitation patterns over 3 years, and in temperature over 50 years, although the change was much slower in the tropics.
Based on that definition, the end of glacials, which takes thousands of years, counts as abrupt, whereas a similar warming from AGW over a century or two may not count as abrupt if it follows change of forcing smoothly. There is, of course, a considerable risk that it will not.

chriskoz at 15:01 PM on 23 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
The range of effects of the myth (from being debunked to 100% backfire) depends on the way the myth is presented. So, the issue herein boils down to the accurate, and easy to understand by the intended audience, presentation by the communicator. Note, that the intended audience must also be considered. A person with phD in the rellevant or related field is interested in different details than a newbe person.
But above all, the myth should be clearly labeled as a falsehood, with simple and unambiguous words, the simpler the better, especially if expressed not the target person's main language. Complex words as well as colloquial jokes will create confusion. So jokes and satire is IMO unacceptable.
As an example: a badly frased poster confused even myself, because it used some complex words and some thinly veiled satire. If I was a climate science conspiracy theorist, this poster would only reinforce my opinion. Much better wording of the poster would be simply:
"A plucky band of bilionaires [...] created a plot: '...'; but the plot is an absurd falsehood"
which states unambiguously what the myth is and does not allow it to stand but debunks the myth in the same sentence.

A lot of energy is being expended on persuading doubters about the reality of climate change. (I'm excluding those who are ideologically wedded to their denialism.) The doubters, however, are actually victims of the "propaganda war" (Stefan Rahmstorf's term) on climate science. Would it not therefore be more effective first to sketch the nature of this "war" and then follow with details of how they've been deceived?

bjchip at 09:16 AM on 23 June 2017Claiming that Listerine alleviates cold symptoms is false: To repeat or not to repeat the myth during debunking?
Random people or educated people? I think that something like this is going to be an important variable. People who are familiar with and used to logical and analytical thinking may be more competent in accepting the debunking and having it override false information than people who are not. People who rely on their gut and their belief system rather than analytical thought would be more vulnerable to the repetition than the debunking. Effect will depend on audience.
One other thing. Reading this I tripped over this phrase...
"our studies remain moot on whether familiarity backfire effects will occur in other circumstances."
In most cases we see mute used incorrectly. In this case however, mute (silent) would be (I think) more appropriate than moot (hypothetical - open for debate). YMMV. I simply know that it caused my reading process to stumble to a halt for a wee while.
I think that this is important. To debunk effectively one has to explain at least once what the error is that is being debunked. OTOH, and this is important, in many forums the subject is set by the original post. Often it is worth debunking by starting a new post because when looking at the subject lines there is an obvious propaganda value to those, and no matter how well you debunk in your response, you just repeated the error in the subject... which may well be all that most people ever see..
Be careful out there
respectfully

Very illuminating. It's good to hear this familairity bakfire effect is not always as strong as feared, because it's very difficult addressing science based myths or issues (or anything serious) without putting the key points up front at the top of discussion. It becomes confused and looks like something is being hidden or dodged to do otherwise. Your research is preliminary, but I thought the experiments discussed in the links were reasonably convincing.
The familiarity backfire effect has also been studied and discussed as related to economic, social, and poltical debate as well, with some views that its better to avoid attracting attention to negative problems, and instead simply either go on the offensive, change the subject, or accentuate the positive or bury the problem text in the middle somewhere. Some say "explaining is losing". However I dont think you can apply this strategy to science. We expect manipulative spin from politicians, but people will be less forgiving when academics indulge in it.
The research appears to show the familiarity backfire effect doesn't have much effect on people already familiar with a myth, or who are prepared to study it in detail and listen. I think the real problem is that when myths or problem issues are put at the start of discussion, theres a risk some people wont read more than the myth, so see what the counter arguments are, or just skim the counter arguments only briefly, so the myth might spread. It's similar to the use of "click bait" headlines in the media, that are exaggerations, spin, or simply false, but many people dont read past them so are left with false beliefs.

Art Vandelay @5:
The period 1921-1980 was 0.06°C and 0.05°C colder in the Berkeley Earth and NASA record respectively than their reference period 1951-80, so including those 30 years would make the temp anomalies that much larger, not smaller.
Note: Berkeley Earth presents two versions of their temperature record, but they recommend using the one with air temperature above sea ice, not water temperature below it. -
Seymour at 00:20 AM on 23 June 2017SkS Analogy 3 - The Greenhouse Effect is Like a Cloudy Night
Isn't this example a little more than an just an analogy? A cloudy sky implies higher relative humidity. Water is a greenhouse gas, which will absorb infrared radiation and return some of it to the ground. I think most people would expect a more gradual temperature drop at sundown in humid climates than in dry climates, even without cloud cover. The only difference seems to be that clouds are visible but greenhouse gasses are not. Isn't the same effect noticeable during a total solar eclipse? In other words, isn't there a more gradual temperature drop during a solar eclipse in humid areas as compared to dry areas? How measurable is the effect of 45% more CO2 and 124% more CH4 in the atmosphere on the rate of temperature drop? If we compare the rates of temperature drop we measure now during a solar eclipse with the rates measured before the Industrial Revolution would we notice a difference? I guess I'm asking for a quantitative estimate of the difference. Given that an eclipse moves so quickly over the earth's surface, I would expect that the radiative effects would dominate convective effects. A total solar eclipse will cross the United States in August. Could this present a teaching moment on the greenhouse effect or is the effect too small?

It is very 'telling' that the Leadership of the Universities that have not signed on to "We Are Still In" have not provided a detailed 'explanation' for not signing it.
As leaders of institutions where new reasons and potential better understanding are constantly presented for investigation, consideration and challenge by other well informed people, they are undeniably aware that a 'Good Reason' will stand up to scrutiny and challenges, while a 'Poor Excuse' will stick out like a sore thumb (especially when that excuse is being rationally considered by a person who is well aware of Good Reasons for signing on to "We Are Still In".

Tom Curtis at 10:29 AM on 22 June 2017New Video: John Cook and the 97 Percent
Curiousbev @2, scientists have had considerable discussion of the input of fresh water from the melting of the Greenland icesheet on the Atlantic Meridional Overturning Circulation (AMOC). This has been discussed in the IPCC AR (Chapter 10), which concluded that:
"Taken together, it is very likely that the MOC, based on currently available simulations, will decrease, perhaps associated with a significant reduction in Labrador Sea Water formation, but very unlikely that the MOC will undergo an abrupt transition during the course of the 21st century. At this stage, it is too early to assess the likelihood of an abrupt change of the MOC beyond the end of the 21st century, but the possibility cannot be excluded."
It was also discussed on the IPCC AR5 (Chapter 11), which was more cautious, concluding:
"Overall, it is likely that there will be some decline in the AMOC by 2050, but decades during which the AMOC increases are also to be expected. There is low confidence in projections of when an anthropogenic influence on the AMOC might be detected (Baehr et al., 2008; Roberts and Palmer, 2012)."
That low confidence, however, means the current influence of AGW on AMOC is weak, so that the possibility of an abrupt change in the 21st century is still low.
With regard to the possibility of a change in the AMOC initiating a new glaciation, Dana Royer has shown that such an event is unlikely with CO2 concentrations of 500 ppmv or above; and hence very unlikely given AGW
Moderator Response:[PS] Another recent paper looking at this is here but not expecting anything dramatic this century.

Paul D @11, yeah the daily mail have tried to distract attention from the real causes with a classic red herring fallacy and some emotional crowd manipulation.
As you point out fire safe panels would have cost almost nothing more. The media has also said there were no fire alarms, smoke detectors, stair pressurisation, and smoke stop doors, and these things are relatively inexpensive and provide at least basic safety, and would certainly have saved lives.
Sprinklers are worth mentioning. These are expensive to retrofit, but they have been shown to reduce property damage and save lives by approximately 50%, especially in risky occupancies with highrise buildings and kitchens etc. Houston in America has made it mandatory to fit these to old buildings, but have given owners some help with finance through some sort of tax concession and depreciation allowance. Britian has put it in the too hard basket. Sprinklers also sometimes significantly reduce insurance premiums.

Agreed, universities should join this coalition and show leadership. But perhaps these universities are worried about a backlash if they openly join this coaltion? Backlash could come from a variety of parties sceptical of climate science, and influential in education.
Some people probably think the laws of science can be "negotiated". There is a powerful, toxic, anti science, anti intellectual bullying movement in America, and it want's to control what universities do. It is utterly delusional, and will lead to ignorance, and your economic and social destruction. It's a return to the stagnation and values of the fuedal middle ages period.

i'm able to run the android_app after installation for a (very) short time.
after a while it is only possible to find infos in the news and about section.
the main menu (browse) and the "top arguments" are "empty".
reinstall the app deliver same results :(

Art Vandelay @5, I don't think that is correct. While it is likely that the 1940s were warmer than the 1970s, the 1920s and 30s were definitely cooler than any following decade:

Worth noting that the temp anomaly was referenced against 1951-1980 which was a relatively cool interval thanks to AMO / PDO phases, so the anomaly is made to look slightly more severe that what it would if the previous 30 years was also included.

Most, if not all residental towers don't allow access to the roof, even in cases of emergency. Not sure if it would have helped in this situation but given that residents on higher floors were effectively isolated by the extent and severity of the fire on lower floors, going up was the only viable option but was apparently not available.

WatrWise @20 and prior posts,
you will have to explain yourself rather more clearly. You are coming across as somewhat confused in ideas & terminology.
(a) Scientific information is not a "product" requiring marketing (a very nebulous term, in itself). Perhaps you mean "how best to educate people" .
(b) The essential problem with education (in this particular case) is that there is a widespread highly-determined strongly-funded effort by vested interests, to oppose real education. That effort includes both a corrupt pressure on politicians and deceitful propaganda to the general public. That's a Double Whammy — and it will be interesting to hear your own ideas on how to counter that, reasonably effectively.
Moderator Response:[PS] This is not the place for such discussion. It has nothing to do with the topic of this thread. Nothing further on this thread unless it is on-topic please.

Without malice or criticism I have put forth that “selling or marketing” climate science/change could improve acceptance by the general public. In response you have just given a perfect example of why many people reject your “Truth”.
Moderator Response:[PS] Sorry but in science integrity has to come first or it is no use at all. Marketing - not so much. Either we are warming or we are not. We are to blame or we are not. You cant have your truth and mine being different. Empirical science seems the best way to answer that question. Ideological/identity-based motivated reasoning seems the worst and yet it seems to dominate especially in the USA.

Apologies for double posting! Error addressing previous post!
nigelj@17 Mr. Nigel it is! My comments were/are not ment as criticism. My goal is to discuss how to move the climate change message forward. I agree that - given an inspired message - people will readily follow.
While I agree that we should not narrow the playing field, perhaps focusing the message might speed things up.

pjcarson2015 @5, the continuous parade of climate "skeptics" who pontificate on what "AGW predicts" without ever bothering to look up what climate science actually predicts is tiresome. In your case you claim AGW predicts a stronger greenhouse effect on Earth, whereas it actually predicts a much weaker GHE on Mars:
On Earth, as a convenience, the effect of the greenhouse effect is determined as a function of percentage change in the atmospheric concentration of CO2 on Earth as a convenience, but in the full theory, the effect of the greenhouse effect is determined by the partial pressure profile with altitude of CO2 (and other greenhouse gases).
High partial pressures of non-IR active gases (such as O2 and N2) can effect the strength of the greenhouse effect by lifting CO2 to a higher altitude, thereby increasing the partial pressure of CO2 at that altitude. But without the GHG, IR inert gases will have no greenhouse effect, and no tendency to increase surface temperature above the simplified black body estimates. (They will slightly increase surface temperature by equalizing temperature between poles and equator, but the simplified black body estimates assume equal temperature at all points, so this effect cannot raise the temperature above that value.)
For a more detailed account of what "AGW theory" predicts about the temperature of Mars, I refer you to Toigo et al (2012).
Moderator Response:[PS] I think pdCarson has outstayed is welcome. No further comments please.

WatrWise @15, thanks. It's Mr Nigel as opposed to nigella. Doesn't matter anyway.
I may have missinterpreted your first post, you came across as a climate sceptic asking long lists of annoying questions. Maybe you are not.
I find it hard to see scientists being able to do more. Their prime duty is the science, and communicating this. They have done this very well over many years, being very particular to explain both in detail and also with simplified versions, and being very particular what aspects they are certain about and what they are less certain about. I mean what more is possible? You can lead a horse to water, but cant force it to drink.
I think humans are largely followers, by nature, and so leaders are needed in the climate issue like with anything else in life. Ideally it should come from corporations and politicians, but there are clear impediments in the way. Im not sure we can expect it to primarily come from scientists other than leading on the science, and by personal example as many already do
However if you look at history many issues in society reach "tipping points" with the public and / or leadership and things suddenly start to change more dramatically. I think we may be getting near that point on climate, maybe this dedcade, but it will only happen if everyone from top down pushes for change.
I would stress that ideologically I personally see reducing emissions requiring both personal, collective, and government and corporate efforts in combination, as opposed to trying to suggest it should be more narrow.

Pjcarson2015, the reason temperatures on mars are a bit cool despite high CO2 concentrations might just be something to do with very low atmospheric mass, and very low surface pressure, compared to both earth and venus. Mars also has a lack of water vapour, and mars gets considerably less sunlight than earth.
I'm not a scientist, but even I can figure it out. You have a phd in thermodynamics? I simply do not believe you, full stop.

Thank you for your prompt replies.
First, I apologize for my overbearing entrance into the debate over responsibility for climate change.
My concerns are centered on those “responsible” for climate change accepting responsibility. My attesting to personal mitigation of climate change will not answer this question; though I have in my own small way tried to mitigate my own climate change footprint.
NigelJ @14, in his/her third paragraph and continuing, makes an excellent effort to answer my questions.
I agree with Nigelj that governments and corporations are principally responsible for climate change.
My observation is that the scientific community is better equipped to promote societal change as well as governmental and corporate change. The individual is very limited in this regard.
As I stated, while limited in their ability to affect change the individual will be stuck paying for mitigation of climate change.
The scientific community has an obligation to improve its climate change message in order to make progress.
Moderator Response:[PS] Suggestions welcome. The scientific community is throwing enormous effort at this but unfortunately cant cure wilful ignorance.

OK Moderator. Mine is simply a thermodynamic statement; difficult to refute. (My PhD is in that area.) You just can’t simply write that what I’ve written is wrong, without showing why.
My observation fits the Greenhouse effects on Venus, Earth and Mars, something which AGW’s known to be incorrect redefinition of Greenhouse Effect (see eg Wikipedia and countless others), cannot.
[Mars has 14x CO2 level of Earth’s but almost zero Greenhouse effect – in line with the total pressure being so low. You can get an expanded explanation at my site.]Moderator Response:[PS] Then use your PhD skills to read a text book on radiative thermodynamics instead of framing nonsense.Starting with the GHE is NOT a temperature resulting from heat held by gases. If you learnt that in your PhD, then you need a refund.
Unfortunately, your skills dont seem to include how to understand our comments policy.

Regarding the comment by WatrWise "Do individual people living in developed countries bear any responsibility for climate change? Remember individual people in developed countries will ultimately have to bear the cost of any mitigation of climate change."
I do not understand this question. Does it mean are individuals responsible for causing climate change as against other parties? Or does it mean are individuals responsible for reducing emissions, as perhaps against governments or corporations? Or does it mean are individuals in the west responsible for problems caused by people in the third world?
But here are some attempted answers. Individuals are causing climate change varying dependent on their lifestyle. That much is obvious.
But governments and corporations are responsible for causation as well by continuing to drill for oil, and by not offering alternatives that we know have viability: renewable power, recharging stations for electric cars,etc.
Individuals are responsible for fixing the problem as an issue of personal responsibility as noted above. But it goes further, I would contend its always ideal that individuals take the initiative, but history shows this doesn't always work sufficiently to resolve community scale problems, so communities and governments have historically imposed rules, taxes and limits.
Certain corporations also have a responsibility for both causing climate change, and reducing emissions. Again it would be nice if they didn't have to be asked, but history shows corporations have a poor record of using their own initiative in fixing environmental problems, so governments have set rules, penalties, and sometimes taxes (that dreaded word, do forgive me).
I dont think individuals in the western world have responsibility for choices made by people in other countries, but given western countries have been the biggest emitters, and some small countries could end up in dire straits over climate change, the humane thing is to assist, just as countries often do with other natural disasters.

Eclectic at 11:26 AM on 21 June 2017Explainer: Dealing with the ‘loss and damage’ caused by climate change
Watrwise @11 ,
on your first point ("call for action"), the required realistic actions are very obvious — reduce CO2 emissions to "net zero" as quickly as practicable. Perhaps it is better to turn the question around :- What realistic actions do you consider should be taken?
Second point :- for 30 years or more, the scientists have been pointing out that the AGW problem is severe — yet ultimately it is the politicians that bear the responsiblity for action & inaction. But the Past is unchangeable : so it is better if you turn your attention to dealing with the present & the future.
Your third point really leads back to the fundamental question :- Are you your Brother's Keeper? Society is made up of individuals. And so each individual has personal responsibility to contribute to the health of present & future society (and the health of the planet itself, of course). Can you argue otherwise?
Watrwise, you raise a large number of other points — but those are relatively trivial in comparison with your first three. Best if you address & discuss the first 3, before proceeding.

nigelj at 11:15 AM on 21 June 2017Explainer: Dealing with the ‘loss and damage’ caused by climate change
WatrWise @11, your post is a very long list of rhetorical questions. I find such long lists of questions to be by definition content free, and extremely irritating, reminding me of aggressive lawyers, so it just gets my back up, and is not conducive to open and useful discussion.
One or two perceptive rhetorical questions can clarify, but your list of over 10 is just ridiculous. We are not your students, Mr / Mss Waterwse.
It's especially frustrating because I know a simple google search would answer many of your questions, so why didn't you just do that first?
And most of your questions are off topic.
One point is worth comment because it demonstrates what I'm getting at. You say "Over 120 years and science cannot accurately predict climate change, even with evolving technology; why?"
If you had done a simple google search, or taken a more relaxed approach to your writing, instead of trying to intimidate people with long lists, you would know that some climate influences are known to be chaotic or variable (like el nino cycles) and so models will probably never be 100% accurate, no matter what technology is available, same issue as predicting outcomes of illness. But climate models have shown useful and reasonable levels of accuracy.
Sceptics like have been told this a million times, and still dont get it. I mean it gets to a point that you are just exasperating, and I dont want to know you people any more.

The Greenhouse effect is a temperature - that resulting from the heat held by all the gases in the atmosphere.
Therefore, ALL gases in the atmosphere are greenhouse gases.[It is immaterial how the gases absorb this heat, eg by convection, conduction, diffusion or infrared. That is an (infra) red herring!]
The amount of heat each gas component holds is roughly in proportion to its percentage.
Therefore, as carbon dioxide’s level is only about 0.04%, its contribution to global warming is puny – perhaps 0.01C!Moderator Response:[PS] Sloganeering. You cant start with a incorrect understanding of the greenhouse effect and then expect to prove it wrong. Firstly, try to understand how the greenhouse effect works - virtually everything you said was wrong. I recommend Science of Doom, for good textbook treatment. If you still want to object, find an appropriate topic (use search or argument buttons at top) and support your argument with references/data. Your objection needs to fit with all of the observation/measurements made, including direct measurements.
