waterguy13 at 12:29 PM on 11 December 2018Trump's disbelief won't stop dangerous climate change
Ok....I learned my lesson: no more illustrating absurdity by being absurd. Instead, a question: Why is this chart presented as factual when it is entirely hypothetical? I would ask for the data, buit since it is hypothetical, it is, therefor, based on assumptions that I am not interested in.
Moderator Response:[PS] The source of the chart is stated beside it and methodology can be found there. An assessment of wildfire without climate change is self-evidently a model output. Please desist from strawman arguments. You can find more about how such assessments are made in the source or for instance here.

scaddenp at 11:11 AM on 11 December 2018Climate change science comeback strategies: 'In it for the money'
SkS prides itself in backing its debunking with published science. You could always post links to the science papers instead of the SkS post and ask for peer-reviewed research to back denier assertions. That said, someone who is vested in denial isnt capable of critical thought. However, demonstrating substance over flim-flam is helpful for curious enquirers.

I found an interesting chart that also presents hypothetical data. The analysis appears to be very similar to the chart for wildfire data in the post. I am not certain that I believe either data set, since they are both hypothetical.

Doug_C at 10:04 AM on 11 December 2018Australia - Moving to Renewable Energy
Australia seems idealy suited to a transition to low carbon renewable energy with plenty of sunlight and other energy resources. Grid scale electricity storage also has a number of different options which can be tailored to the required situation. Some like redox-flow batteries are only economical at the grid scale and can have a virtually unlimited lifespan.
How three battery types work in grid-scale energy storage systems
Australia also has vast geothermal potential at a relatively shallow depth in much of the central and nothern part of the nation.
It's good to see that real change is taking place in Australia, but it also seems to be the case that like here in Canada there are still too many policy makers who are saying one thing and doing the opposite.
The global priority is to phase out all fossil fuels as quickly as is feasable starting with the most polluting like coal and unconventional oils like tar sands bitumen. Then moving on to light crude and natural gas until all energy production is fossil fuel free.
And yet there are still many who keep demanding we build more coal fired power plants or here in Canada who want to vastly increase the pipeline capacity from the tar sands to get significantly more bitumen to market where it will be burned creating an even more massive carbon dioxide plume than we are producing now.
I found it a little ironic that a few weeks ago when Australian school kids walked out to protest government inaction on climate change a minister commented that they were wrecking their future.
Australian kids walk out of school to protest climate inaction
No one will have much of a future at all if we don't make these essential transitions and as soon as possible. This has been under debate for almost a half century now, the time for talk is long past we need real action that actually significantly reduces carbon dioxide emissions.

Australia is moving in the right direction
There seems to be some sort of cognitive dissonance here, last year saw our emissions at the highest they've ever been and 2018 looks to be higher still. Moving in the right direction ? I'd suggest moving more slowly in the wrong direction is a better representation of what's happening.

I poked around the internet, and found few places where one could discuss climate issues. It is like Trump and anti-Trump but even more decisive. One site I registered at, but never left a post. I just wanted to use their internal search to find content with some grain of reality. If you post there and claim any of the facts one can find at skepticalscience.com etc. you are immediately labeled a "parrot." So this message is going to be difficult to spread, as those willing to discuss any actual detail (light, CO2, reflections, IR, etc) the layman convinced of climate change really does not want more detail and the denialist is impossible to engage.

Maybe the COP24 final statement can be done like the US Supreme court rulings. The majority position is presented as the ruling position (the determination of what is correct), and the minority get to present their alternative opinion (based on alternative facts) and attempt to justify why people should believe that they are Right (the alt-Right).

When I named the USA, Saudi Arabia and Russia in my comment at 7 my main motivation was that they appeared to be the strongest examples of the potential results of poorly regulated or poorly limited activity in the more developed/wealthy nations (incorrect power in the hands of incorrectly wealthy people). They had developed very powerful incorrect leadership (China can become just like them, or it can develop in a different direction - I am watching to see which way their leadeship development actually goes).
Now I am reading about the refusal by the USA, Saudi Arabia, Russia to admit to the awareness and understanding presented in the recent IPCC climate change impact assessment.
The Guardian report "US and Russia ally with Saudi Arabia to water down climate pledge"
The current leadership of those nations truly stand alone in their divisive polarization away from improved awareness and understanding. They are acting for the benefit of incorrectly developed wealthy people.
The actions by the Trump led WH regarding Russia and the Saudi Arabia make a lot of sense in the context of their leaders having personal wealth motivations to do the undeniably incorrect things they are doing regarding climate chiange and many other issues that matter to the future of humanity.
As a post script: Kuwait is just a nation in the Middle East the USA took explicit control of when Saddam's Army was pushed back all those years ago. It has been a puppet nation of the USA ever since the USA invaded and took over control under the excuse of Freeing the nation (like they later did to Iraq).

DrBill @53,
If you do want TPW as a proportion of total atmosphere, you'll need to stick with mass and you'll probably not get much improvement on Wikipedia for the mass of the atmosphere, giving 5.15 x 10^15 tonnes. And for the mass of global TPW, Trenberth et al (2007) gives a value of 12,700 cu km or 0.0127 x 10^15 tonnes. There are positive trends in global TPW but these are some 1%/decade so the upward trend is less than the uncertainty in the total.

I feel Macron's carbon tax is the right general idea, but it is too blunt in its design. It's too harsh on lower income people, and so he has a basically annoyed everyone on all sides of politics and given a platform for extremists and opportunists. He should have compensated poor people with some sort of assistance package, or adopted tax and dividend and it's mystifying why he did neither.
This short youtube video from the economist.com sums the situation up well.

@6 BeezelyBillyBub,
Not all meat production is a net emissions source. Properly managed it can be a large carbon sink. So this idea of taxing meat is doomed to failure as a AGW mitigation strategy before it even starts.
Now if you instead taxed all CAFO meat production and used that money to subsidize verified carbon sequestration in the soils of properly managed farms. Then you might have something.
Your ideas as they stand though, across the board, are far too simplistic to be effective at all on complex systems such as AGW. The meat comment being just the most obvious one.

Well TPW is the total of all water in the atmosphere. However, it is expressed in millimeters normally. Multiply by surface area of earth to get volume and by density to get mass. I am not sure you gain any new information from that that wouldnt get from just looking at TPW. Given the uncertainities in determining TPW, you now add uncertainities measurement of atmospheric mass.

I agree with John Hartz. Al Gore did not politicize climate change. And there are not 'Fine people on all sides of the issue'.
My sense of what has happened is:
- The global community has 'continued to improve the awareness and understanding of what is really going on and what is required for the development of sustainable improvements for humanity into the distant future'.
- The improved awareness and understanding is identifying that a lot of the developed socioeconomic-political systems are incorrectly producing perceptions of superiority relative to others that need significant correction to reduce (and ideally eliminate) the harm being done (are ultimately unsustainable).
- People who have incorrectly developed perceptions of opportunity for prosperity or superiority relative to others are divisively polarizing themselves away from the improved awareness and understanding.
The resistance to the improving awareness and understanding of climate science is just one of the biggest and most recent cases in the envelope of all the cases of 'developed popular and profitable activity that is discovered to be harmful after it has developed into an undeniably big enough problem that is harder to excused or ignore'.
And I am bemused by people who claim there is 'another more important correction', like the plastic waste in the oceans or the cases of extreme poverty that still exist (in spite of global wealth growing much faster than the global population), because they are basically bringing up other cases in the same envelope that climate change is in 'the cases of incorrect development of perceptions of superiority relative to others any way that can be gotten away with, especially in ways that are unsustainable and understandably harmful to Others (and the future generations of humanity are the largest group of Others, and they are easy to negatively impact because they don't vote)'.
What can be seen to be happening is that:
- Leading up to and since the 1972 Stockholm Conference, there is evidence that many parties were investigating the potential unacceptability of aspects of developed human activity.
- Global collective collaborative improvement of awareness and understanding has continued to progress to the current 2015 Sustainable Development Goals (and the Paris Agreement that is action to achieve the Climate Action Goal), and is likely to continue to progress in spite of efforts to stifle and discredit the efforts.
- People who have become aware that the improving awareness and understanding threatens their developed perceptions of superiority have been trying to divisively polarize as many people as possible away from the improved awareness and understanding (they have been keeping people from learning how incorrect their developed beliefs and preferences are by harmfully applying the improved understanding of how to influence people.)
- Many people have been easily motivated into liking harmful attitudes, like greed or intolerance, and divisively polarize themselves away from the improved awareness and understanding of the corrections required for the future of humanity. And people who have less interaction with a diversity of other people (and have developed a smaller worldview), can be more easily impressed that way - hence the divisive polarization of less urbanized, less globalized, populations against 'those Others, especially against those Others who try to tell them that they are incorrect to like (and dislike) what they have developed a liking (and disliking) for'.
The root of the problem is the systems that develop people who have 'Won' by incorrectly developing ultimately unsustainable perceptions of superiority relative to others. A major part of that problem is the way that developed popular beliefs can be difficult to correct, especially if the beliefs develop and support incorrect but profitable activity.
And that leads to the understanding that a diversity of places including the USA, Saudi Arabia, and Russia are in need of significant correction, because they have all allowed people to develop significantly incorrect perceptions of superiority relative to others. And that understanding extends to recognizing that many other regions face the 'competitive pressure' to Win by more incorrectly promoting and excusing harmful unsustainable beliefs and actions - the classic “Why should we behave better when we think others are improving their chances of Winning by getting away with behaving less correctly” - which is undeniably a competitive spiral to behave as harmfully as can be gotten away with.
So Al Gore did not politicize the issue. And 'alarmists' who try to raise awareness of the potential extreme results of reluctance to act to correct what is causing the climate changing impacts (extreme results that become increasingly likely results with every year of inadequate corrective action), are not polarizing the issue. People who do not like the improved awareness and understanding are politically divisively polarizing themselves (and as many others as they can get away with easily impressing) away from the improving awareness and understanding of the required corrections.

Here is a recent climate change impact story about a new potential impact issue.
Climate change could wake up Canada's dormant volcanoes The National (video part of News Broadcast), CBC News, Dec 5, 2018 - Scientists at Simon Fraser University argue that climate change is destabilizing volcanoes around the world.
This type of impact is not included in evaluations that try to claim that imposing climate change impacts on future generations is Just Fine (justified). And many already anticipated impacts are excluded because they are 'not certain enough to negatively impact the richest enough to be included in the evaluation'. And even the negative impacts included in those evaluations get 'discounted', meaning they are evaluated speciofically from the perspective of the current day richest.
Those evaluations incorrectly try to claim that the activity today that is creating the future problems will have develop sustainable wealth that grows into the future, gaining a value that exceeds the costs of climate change impacts. My MBA training helps me understand the fallacy of that type of evaluation. Perceptions (or measures) of wealth that are due to unsustainable or harmful activity will not continue to be wealth into the future.
And, in addition to the understanding that current government leaders are being incorrectly influenced to make-up and promote poor excuses for continuing to allow more harm to be done to future generations (to protect incorrectly developed ultimately unsustainable perceptions of prosperity and superiority), winning Leadership is also failing to support added investigation into, and monitoring of, new potential climate change threats like this potential for climate change to result in a major volcanic event to occur near a heavily populated part of Canada far sooner than it would have otherwise occurred.

MA Rodger @52 Not sure how it can be cleared up. There is a total atmosphere mass and volume. There is a total of all water/water vapor in the atmosphere, also at least by mass, and thus convertable to volume. Someone might have divided total water/water vapor by total atmosphere mass and I'd like to find that data.

It is very tricky to go from attribution of the climate change component of extreme weather to convincing skeptics. To begin with, skeptics are not skeptical, they are flogging excuses and long-debunked favorite "urban myths". There is no good faith, and hard physics about CO² absoption spectra are likely harder to ignore than aberrant weather. Moreover, on popular media people often list weather events which themselves (out of context) are not all that extreme. This only serves to muddy the thinking all the more. Attribution works with statistics and probabilities and ranges of certainty ... these are not good material for convincing stories. Pointing to local weather phenomena seems a dubious strategy, all things considered.

John Hartz @3, I think the issue with Al Gores book is it was written by a well down prominent Democrat and so gave the Republicans an easy excuse to ignore the climate issue because they dont like Al Gore. It was an excellent book but unfortunately its created some of the division even although the content should count, not the writer. Maybe I could have been clearer.
I was being general about fault on both sides of politics. Democrats don't get everything right, even on the climate issue, and I didn't want my comments being crossed out as excessively politically one sided.

As a citizen who has followed US national poitics for more than sixty years, I take exception to your statement. The fossil fuel industry and their political allies "politicized" man-made climate change long before Al Gore's book came out. You should not state that there is "fault on both sides."

No doubt there will come a point where more extreme weather is so obvious and undeniable, that most sceptics will finally undersand, but that point will come too late. I think we have to hammer the message that more heat energy must lead to more intense and frequent heatwaves, stronger hurricanes and more intense rainfall, because its basic physics, and also generally supported by empirical evidence over recent decades.
They say facts don't change peoples minds. Maybe with the most dogmatic and politically tribal, but I think its a nonsensical statement really. The article clearly shows once sceptical people accept weather is changing, ie it's a fact, it changes their minds.
A lot of people really struggle with science, its a hard subject but persistence pays off.

Related research: Political ideology and views about climate change in the European Union.
"There is a strong political divide on climate change in the US general public, with Liberals and Democrats expressing greater belief in and concern about climate change than Conservatives and Republicans. Recent studies find a similar though less pronounced divide in other countries. "
I live outside of america and a lot of the tribalism in America seems generated by conservatives. Calling people libtards, constantly trying to shut down government and growing conservative opposition to environmetal laws doesn't help.
Sure theres obviously some fault on both sides. Al Gores book politicised the issue within America, but it seems fault is skewed towards the conservatives I'm afraid. Barrack Obama and Bill Clinton seemed to bend over backwards to compromise but were both vilified, and are accused of being hard left. It's remarkable, because in my country the democrats are considered a practical, moderate centre right party!

One Planet Only Forever at 01:42 AM on 9 December 2018Trump's disbelief won't stop dangerous climate change
Doug_C @17,
I agree with the importance of the scientific method and what has been developed by technical science and its application.My objective is raising awareness and understanding of the importance of developing a larger worldview, a worldview that leads to people to embrace 'personally act now in ways that support the achievement of local and global benefits now and far into the future', rather than people only caring about their personal interests in the very near term (which can include prolonging harmful incorrectly developed beliefs and actions).
A lot of important helpful improved awareness and understanding is not 'new results of technical scientific investigation'. And a lot of it is identifying required corrections of the results of the applications of technical science, especially when the scientific investigation and application is driven by competition for perceptions of superiority relative to others driven by popularity or profitability. A particular concern is the harmfully incorrect applications of marketing science to attempt to increase and prolong understandably incorrect activity. A related harmful incorrect behaviour is claiming that correction of what has developed cannot be 'forced to happen (by external judges/referees of the game)' unless there is 'scientific certainty , of the exact mechanisms and details of harm done by the popular and profitable activity (to the satisfaction of the people who do not want to be corrected)'.
A recent example is the delays in action to limit the use of neonicotinoids until the potential harm they are causing is well understood. The argument is that they are now popular and profitable - and help end poverty - so the use can only be allowed to be forced to be stopped if there is very explicit and robust proof of the harm done (and maybe not even).
Similar incorrect arguments are used against efforts to reduce the burning of fossil fuels. And the burning of fossil fuels are also defended by the claim that new technical science developments will be the answer. The claim is that new technical developments must occur to solve the problem, implemented in ways that do not damage incorrectly developed perceptions.
For many people, understanding the harmful incorrectness of burning fossil fuels is not enough to justify the clearly required correction. Protecting the developed perceptions of prosperity and superiority is claimed to be required. No curtailing of fossil fuel burning until a way to accomplish it is developed that does not correct the incorrectly developed perceptions of prosperity and superiority.
And that is the core of the temporary regional success of the likes of Trump. The likes of Trump gather support by making-up claims to defend the incorrectly developed perceptions of opportunity, prosperity and superiority. They do it to keep people from improving their awareness and understanding of what helps and harms the development of a sustainable better future for humanity. And that would explain why their strongest appeal is in non-urban areas (like the pro-Brexit regions in Britain, and the source of the violent anti-climate action protesters in France). Their ability to get support is greatest in regions where people develop smaller worldviews, where people and can more easily tempted by greed or intolerance to divisively polarize away from improved awareness and understanding of how to help develop sustainable improvements for all of humanity.
The Sustainable Development Goals are an example of improving awareness and understanding that is not developed by technical science. Though the Climate Action Goal is due to technical scientific evaluation, it is actually the result of improved awareness and understanding of the harmful unacceptability of popular and profitable developed applications of technical scientific learning. And many of the other Goals are the result of improving awareness and understanding of the harmful unacceptability of other developed results of human competition for perceptions of superiority relative to others that require correction, especially developments driven by pursuits of popularity or profitability.
In essence what I am suggesting is that the most important improved awareness and understanding is that the currently developed socioeconomic-political systems are actually causing lots of harmful incorrect developments, and making it difficult to correct them.
The developed socioeconomic-political systems need to be corrected. Without correcting the system, more technical science is likely to be more harmful. Without system correction, it is likely that incorrect harmful new applications of new technology will be done 'to solve the problem'. The results of that 'type of solution' could be more harmful than the problem that needed to be solved.
That modification of understanding does not change the fundamental understanding that any 'solution' developed by the likes of Trump is almost certain to be a Very Bad Idea.
And hoping for a better future for humanity without correcting the socioeconomic-political systems that developed winning by the like of Trump would be like that definition of Insanity “Continuing to do the same things, but expecting a different result”.

DrBill @50/51,
You still do not make clear what data you are seeking. Your comments suggest you are likely after Specific Surface Humidity so Total Precipitable Water is likely not helpful. (Note that the measurements for TPW in mm so equal to Kg/sq m and also equal 0.1g/Kg atmosphere.)
As with temperature data, surface humidity data is quickly converted into anomalies. Thus humidity records like HadCRUH would be of no help to you.
The ESRL NCEP Reanalysis Dataset browser does provide humidity in g/kg for different pressures so global surface values can be obtained by setting the Longitude/Latitude. It's where the data plotted here (usually 2 clicks to 'download yourattachment') was sourced.

The Scientific Method has produced an incredibly detailed understanding of the natural world from the largest scale to the smallest.
Whether it was Einstein following on from the works of very penetrating thinkers before him to detail the relationships between light, gravity, time and relative velocity to those working at the smallest scale to give us a profound understanding of how nature seems to function at a fundamental level.
That was due to people with the mindset that we are never finished asking questions and always open to new explanations that fit the facts as they are constantly revealed.
Then we are faced by those who are unwilling or afraid to even ask the important questions.
One of my favorite lines from reality and entertainment is;
"Let's work the problem people. Let's not make things worse by guessing."- Gene Kranz(NASA Flight Director)
We are in that kind of situation where if we don't get our actions precisely right and in a very limited time frame we could lose life support on Earth for much if not most of the current biosphere.
And people like Trump are so unaware of the true dimensions of this crisis that if they were on Apollo 13 they'd get out and try to walk home.

One Planet Only Forever at 12:32 PM on 7 December 2018Trump's disbelief won't stop dangerous climate change
Doug_C @15,
I agree.
I would clarify that the expanded issue of 'improved awareness and understanding of what is going on and how to apply it to help sustainably improve conditions for humanity' is what has advanced humanity.
That effort is not limited to 'rigorous scientific method' investigation. The scientific method has tremendous but limited applicability to improving awareness and understanding. It struggles to evaluate the complexity of the bigger picure. It is limited to figuring out parts in intense detail. It struggles to evaluate complex things like 'explicitly identifying the mechanism(s) of harm from smoking (a lot going on that is impractical to replicate in a controlled/repeatable study)'.
That clarification does not change the understanding that the likes of Trump are harmful undeserving Winners. And it can allow many more people to be included in the category of helpfully aware and understanding people who are unlike the likes of Trump (and that group of helpful people includes many spiritual leaders and followers).

It's the Charlie Sheen tiger blood drinking warlock type of "winning" that Donald Trump represents.
Not the kind of winning that people like Newton, Maxwell, Pasteur, Planck, Einstein, Currie, Meitner, etc.. represent. The most valuable advances in our species and society have come from the application of the scientific method and a genuine respect for the facts that someone like Donald Trump is a total rejection of.

I think Donald Trump is similar to that group of people that are hugely personally ambitious and egotistical, but more importantly cheat the rules with no conscience about the matter. They have few scruples in business.
Humans are driven by status and winning, but we are also conscious of the problems this can generate, and decent societies have systems of rules and laws to stop cheats and people who abuse other people and the environment in the process of promoting their status. We try to keep staus seeking in check.Trump is trying to undermine all this if you look at his policies.
I mean the pattern is absolutely obvious. Trump excuses bullying and violence and criminal behaviour, and has sought to undermine environmental and business regulation.
The first time I was aware of Trump was watching him on the Apprentice. He seemd ok but had absolutely no sense of humour and said a lot without saying very much if you know what I mean. Psychologists seem to think he is a narcissist. I have no argument with that. Such a condition is extreme egotism, exacerbates the desire to win at all costs and reduces conscience.

One Planet Only Forever at 01:37 AM on 7 December 2018Trump's disbelief won't stop dangerous climate change
Doug_C,
I do not see the behaviour of Trump, or the many people like him, as Unusual.
I see their behaviour as understandably incorrect and harmful, but gotten away in pursuit of Winning undeserved perceptions of superiority relative to others.
That behaviour can best be seen in competitive sports. It gets worse the more potential personal benefit there is (very little problem in pick-up games at a recreation level - no rewards for winning). And teams and fans will deny and excuse the understandably incorrect behaviour if accepting it and not having their team benefit from it would reduce their perception of superiority relative to others. And the answer in sports is always increased vigilance and severely penalizing the unacceptable behaviour out of the system.
Competitive pursuits of superiority relative to others in socioeconomic-political games where acceptability is based on popularity and profitability are guaranteed to encourage people to behave as unacceptably as they can get away with. And those type of flawed developments of systems are indeed occurring everywhere. They are in democracies, dictatorships, and communism. They can even develop in more socialist systems, though it is more difficult for that type of behaviour to win big in a strongly socialist society.
The ability of people to get away with abusing the scientific understanding of how to influence people to benefit from misleading marketing is the problem. Successfully keeping people from becoming more aware and better understanding of the corrections required to develop sustainable improvements for all of humanity (far into the future) is Winning Too Much in Too Many Places.
And incorrectly developed ways of living (harmful and unsustainable activity) that has been able to get away with becoming popular and profitable can be very difficult to correct. Many people simply dislike being corrected. But it is even harder to correct people when they can easily understand the personal disadvantage of improving their awareness and understanding.

Cedders at 00:54 AM on 7 December 2018Just how ‘Sapiens’ in the world of high CO2 concentrations?
Craig Idso and others of that ilk have been commenting on a study by Rodeheffer et al (2018), who fail to replicate the effect on the same measure of cognitive ability. However, they are using a different population, and I think shorter exposure. Maybe submariners have become habituated to high carbon dioxide levels, or maybe the sample size is too small. The lack of reported effect on comfort might suggest some acclimatisation.
Allen et al (2015) (free full text) is strongly supportive of the cognitive effect. There's also a new review by Kenichi Azuma et al (2018): 'Effects on cognitive performance begin at 1000 ppm during short-term exposure', but other physiological variables at 500ppm.
Our brains and circulatory systems did indeed evolve in a high-O₂, lower CO₂ world, so this seems plausible, but needs more research. When contrarians ask about the direct human health effects, it is usually a distraction from what is healthy for the climate and biosphere.

scaddenp @5,
Those ENSO wiggles, along with volcanic and solar forces wiggles, have been addressed using MLR to better reveal the underlying tend. Tamino repeated analysis this using annual data (& 2018 to August as a partial year) back in October. This shows the adjusted 2018 is (so far) a little cooler than the warmest adjusted year which is 2017. (The 'As Is' in the graph is the unadjusted values.)

Doug_C at 17:28 PM on 6 December 2018Trump's disbelief won't stop dangerous climate change
There is something fairly unusual going on with Donald Trump and how he relates to most other people and especially the media. This is a man who in the past has crafted his own public image and has largely got away with it.
Trump lied to me about his wealth to get onto the Forbes 400. Here are the tapes.
Trump essentially lied to get on the Forbes 400 list which he then used to get loans and contracts that otherwise wouldn't have been available to someone with the relatively low amount of assets he really had. And no one checked to see what the facts were.
Trump has been rewarded throughout his life by creating his own reality, it's no wonder he's still doing it now. It really is hard to pin down someone who has no respect at all for the facts and who has used a number of different aliases thoughout his life to deceive people.
The fact that someone like this is now in such a position of trust and power is a strong indication of a much deeper issue with US society and government. And the problem seems to be present in many other places as well. When we need real leaders with respect for the facts and the postion of trust they hold we are being let down over and over.
In France Macron who seems to be fully committed to real climate change mitgation just caved to political pressure and has suspended French carbon taxes. Climate change isn't going away, but any real rational sense at a governmental level seems to fading away.
Here in Canada the big dog fight is over the oil sector and how many people are loosing their minds because they can't ram pipelines through wherever and whenever they please.
I think Trump appeals to many people who simply finds facts and reality just too challenging and they would rather stick with a comforting fantasy even if it ends up being fatal on a global level.

While the average IQ is 100 etc and this is a problem, I'm beginning to think "deliberate ignorance" is the greater problem. You see deliberate ignorance with politicians who are smart enough to know better.
I suspect they are driven by simple ideological beliefs and so anything that upsets this makes them ignore reality. It becomes second nature.
Trump is also obviously massively inconsistent, as DougC says. It's something that really frustrates me. This is hopeless in a leader and ultimately creates chaos and policy incoherence. I think it's partly because he says one thing to placate one group, and another opposite thing to placate another group, knowing he will get away with it. He treats people like fools, but they let him do this! Its almost like they enjoy it.

scaddenp at 10:23 AM on 6 December 2018COP24: UN climate change conference, what’s at stake and what you need to know
juddb. Take a long look at the global temperature record. It consists of pronounced up/down wiggles following at upward trend. The trend is climate - 30 year average - while the wiggles are "weather". Those wiggles are the El Nino/La Nina (ENSO) cycle which is chaotic and so far defies any long term prediction. Record temperatures are always set during an El Nino - which last peaked in Apr 2016. You expect temperatures to decline after that. You wont get a new temperature record till the next big El Nino. Climate models cannot pick El Ninos; what they can do pick the trend. Focus on that. The ENSO cycle is just about redistribution of heat on an unevenly heated, wet planet. In the cool La Nina phase heat is being buried in the ocean. In El Nina, that surfaces and heats the atmosphere.
How much lower? We havent had a strong La Nina since apr 2016, it mostly neutral but 70% chance of a weak El Nino in next few months so it will likely go back again. If you look at previous strong La Nina (2011 was a doozy), you will get an idea of far it can go down. Please lets not have a repeat of the "Global warming stopped in 1998, 1995, 2002, 2007, 2010, ????" meme.

Its interesting to look inside the recent IPCC Special Report where you can find that the real-life data shows global temp in decline since April 2016. Its only the computer-generated estimates that are going up and up. Isn't that a little bit suspicious - especially since previous computer projections have been mostly incorrect? I can't help but wonder how much lower global temp might go.
Moderator Response:[DB] "real-life data shows global temp in decline since April 2016. Its only the computer-generated estimates that are going up and up"
Please keep in mind that statistical significance testing shows that, for climate related changes, 17 years (Santer et al) are the bare minimum, with 30 years or more being typically used.
With that in mind, the overall global trends show that the warming continues, unabated, unpaused and unhiatused to the present.
Here's the standard NASA GISS global temperature trend, showing exactly that:
Compare and contrast that with this one, using an 11-year smooth instead of the standard 5-year smooth (and comparing April's, since that was your claim):
A comparison with NOAA shows a similar result, that real-world temperatures show an underlying upward trend in temperatures with natural variability superimposed over it:
As do April global temperatures from the BOM (11 year running average):
The longer the running average/smooth, the more noise is filtered out of the trend, and the underlying warming signal is easier to discern. The only role computers play is to do the math (which could be done with pencil and paper; computers just make the job much faster).
With an understanding of the forcings involved, it is clear that global temperatures will not be going down anytime soon. -
Doug_C at 08:16 AM on 6 December 2018Trump's disbelief won't stop dangerous climate change
Also is talking about Trump's "disbelief" accurate.
He denies very well backed up evidence on a host of issues and there seems to be no such thing as objective information in Trump's world. Everything is an immediate expression of what best suits his mood at the moment.
So one moment he can tell the Wall Street Journal that his administration has no tariffs...
‘Where Do We Have Tariffs?’ Trump Asks. Here’s a List
And the next he is crowing about being "Tariff Man"...
Trump called himself “Tariff Man.” The internet did the rest.
Trump's reality is largely subjective, the moment it becomes advantageous to him personally to accept the reality of fossil fuel forced climate change he will. The question is if he ever will get to the point of understanding it's also in his interests to effectively address climate change by switching to a carbon neutral energy model.

So the Republicans claim that climate mitigation policies would "harm the economy".
They are deluded, and provide no evidence, and in fact the evidence points the other way. Deployment of solar and wind power has helped the economy by providing cheap electricity and increased employment opportunities.
There is no evidence carbon tax policies have harmed the economies of countries that have deployed them such as the UK.
Countries also have to obviously balance economic output with maintaining a healthy environment. To focus entirely on the economy is obviously not useful, yet this is what the White House does consistently, shown indisputably by its policies and downgrading of even the most light weight and commonsense environmental standards.
The harm to the economy is coming entirely from the White House and the GOP, with their tariffs causing price increases, constant backtracking on economic announcements spooking the markets and thus causing crashes in the sharemarket, and unfunded tax cuts increasing the deficit, to name but a few things. The White House focus is entirely on short term superficial gains that cannot properly be maintained longer term, and which come with accumulating costs both economic and environmental, most of which get dumped on the general public.
According to various experts America is now on the brink of an economic recession because of Trumps policies. trends in bonds are a very reliable indicator and they all point toards a recession .

Evan at 05:59 AM on 6 December 2018Is Methane Worse than CO2?? | Climate Chemistry
MA Rodger@11 I see your point and accept your correction on my use of warming potentials where they should be per unit mass and not per molecule. I still maintain that a factor of 100 for methane is more appropriate for the instantaneous effect, because the factor of 86 is for a 20-year period. As long as we maintain CH4 at a high level it is the instantaneous effect that counts. 20- or 100-year periods only matter if we bring CH4 concentrtions down, and we have not, nor is there any indication of that happening soon.
But I do accept your correction that I should be using warming potentials of 86 or 100 on a per-unit-mass basis and not on a per-unit-molecule basis.

MA Rodger at 05:39 AM on 6 December 2018Is Methane Worse than CO2?? | Climate Chemistry
Evan @4,
I think your numbers need a little attention. Having first mentioned atmospheric levels of CH4, you state that in terms of climate forcing, CH4 is "about" 100-times as powerful as CO2 molecule for molecule. You then go on to say "the warming today from methane is about half that of CO2." That isn't correct.
CH4 has about a quarter the forcing of CO2 (as of 2016), or more accurately 0.507/1.985 = 1/3.9 . The rise in CH4 since pre-industrial is some 1.1ppm(v) (to 2016) and CO2 124ppm(v). That would make the molecule-for-moleule comparison CH4 = 29 x CO2.
The Global Warming Potential is a measure of the warming resulting from equal weights of emissions of the different gases over a set period. CH4 has a GWP of 86 over 20 years which is only very roughly about 100. As CH4 is 44/16 = 2.75 lighter than CO2, the GWP would have to be divided by that factor to obtain a molecule-to-molecule comparison, and that for tonnes of gas emitted not the molecues floating round the atmosphere.
