One Planet Only Forever at 09:31 AM on 29 January 20202020 SkS Weekly Climate Change & Global Warming News Roundup #4
It is indeed challenging to ‘now’ correct what has ‘now’ developed. Development down the slippery slope of allowing potentially harmful, or actually harmful, activity to compete for popularity and profit has produced the expected result. The cheaper and easier harmful unsustainable activities are more popular and profitable. And popular and profitable activities develop powerful resistance to being corrected or terminated. And people have an aversion to losing perceptions of status or opportunity. That aversion includes a resistance to learning that what they developed a liking for was actually unsustainable and harmful and needs to be stopped. And that may have been one of the hoped for results of the fossil fuel power players who chose to pursue maximizing the development in the harmful incorrect direction they could benefit from.
The current day fossil fuel majors cannot be defended. It is proper to identify them, and other harmful unsustainable organizations like them, so that people can take corrective actions.
An important understanding is that everyone’s actions add up to create the future of humanity. Everybody needs to reduce how harmful they are and try to be more helpful. And all of the wealthiest should be required to lead the correction, or give up their position of higher wealth (become a commoner).
One of the most powerful influences that individuals can have is doing whatever they are able to do to stop supporting these organizations and their activities, with all of the wealthiest leading the correction. Since everyone’s actions add up, it is not acceptable for any wealthy person to continue to be a trouble-maker requiring others to clean up the mess they make in pursuit of personal benefit.
However, it is important to deal with the identification of the 6 major fossil fuel companies within the context of an expanded awareness and improved understanding of economics (see p.s. below).
An important economic understanding is that nobody’s actions should be allowed to be harmful to another human no matter how much more profitable or popular that action may be. It is a slippery slope to start allowing benefit to be obtained by harming others or the future of humanity.
The current reality is that humanity is well down the slippery slope of harm due to the actions of people trying to benefit from organizations like the identified 6 major fossil fuel corps. That position down the slippery slope is due to the actions of the harmful resistors of expanded awareness and understanding and the related required corrections (Read Jeffrey D. Sachs’ book “The Age of Sustainable Development” or take the MOOC of the same name).
It is fair to ‘not blame’ the developers of an economic activity that developed before it was possible to understand the harm it was causing. But it is also fair to criticize any current day pursuers of benefit from economic activity that has significant doubts regarding its harmlessness. And it is fair to penalize those already more fortunate people who pursue benefit from activity that is undeniably harmful and who are trying to defend it with misleading marketing to influence public opinion, especially those arguing about the degree of harmfulness, and most especially those who discount future negative impacts when they do it.
Sustainable development for the benefit of the future generations of humanity includes understanding the need to have no harm done to the environment of this planet, especially no harm done to the robust diversity of life. An economic action cannot be justified if it is beneficial to an already fortunate person but is contrary to developing sustainable improvements for the future of humanity.
The consensus understanding regarding the need for corrections to achieve sustainable development can be understood to have been reached by global leadership in the 1960s, because that consensus awareness produced the understanding of the 1972 Stockholm Conference and the continued pursuit of expanded awareness and improved understanding of the diversity of topics related to sustainable development, including but not just climate science evaluations of climate change.
That improving awareness and understanding includes learning that many of the current developed economic activities are not ‘steps along a path to a sustainable improving future’. Many developed economic activities are harmful unsustainable actions that have developed ‘resistance to correction’. They are in the wrong direction and go further in the wrong direction and set up barriers to resist redirection to a sustainable path. And they will require Responsible Leadership to rapidly correct them as required to limit the harm done to the future of humanity. Had they responsibly self-led their correction they would not be facing the external imposition of correction that is ‘more harmful to their current more incorrectly developed status’. A related criticism applies to all of the automobile producers. The ability to pursue the development of sustainable corrections has existed for a long time. All that was lacking was the responsible leadership. Decades after an established automaker could have aggressively started the pursuit of development of sustainable alternatives, Elon Musk came along. What Elon did was stimulate the development in a direction it could have been stimulated in long before he started Tesla. And against massive resistance Elon made happen what a responsibly led major automaker could have made happen far earlier.
p.s. A lot of “Economic” presentations people see today, and the related opinions people develop, are ideological political misleading marketing. It is rare for people to be significantly more exposed to presentation by serious pursuers of expanded awareness and improved understanding of economics. What most people are exposed to are people who ‘sound like economists’ being talked to in News-Bity style situations where the details, nuances and complexity are not communicated, because that would take too long, and who has time for that. And some people read books by those misleading marketing ‘economic sounding people’ in the belief that the fuller story is being presented ‘because it is a Book’.
A good understanding of economics is presented in the 2019 book, “Good Economics for Hard Times” by Abhijit V. Banerjee and Ester Duflo.
The authors are serious economists who have spent decades pursuing expanded awareness and improved understanding of how to get sustainable economic improvements of conditions for the less fortunate. Though their focus is on policy recommendations for developing nations, they also apply their knowledge to efforts to assist the less fortunate in more developed nations. And their understanding is also based on awareness of how the currently most developed nations developed.The reality of economics is that very little economic theory has been able to be rigorously tested in controlled repeatable experiments. The understanding develops as a result of more wholistic and comprehensive evaluations of the diversity of economic results in the total global history.
Their book makes many points, but a major point is that among serious economists there are a number of consensus understandings on issues where the public opinions are dramatically incorrect, lagging significantly behind the expanded awareness and understanding of the serious economists. One, but not the only one, that they include that is relevant to interface of climate science with economics is the consensus understanding among serious economists that: A Carbon Tax can help sustainably correct economic development, especially if the collected funds are fully rebated to the middle and lower income groups (the higher income people do not need any rebate assistance).

michael sweet at 09:30 AM on 29 January 2020Sea level fell in 2010
RitchieB,
I do not think that there was ever a "discrepancy" to be corrected in the comments above. The first commentor says they are a "layman" who eyeballs a graph and does some rudimentary calculations. The responding posters cite Llovel et al 2010 which states in the abstract:
"We show that whatever the period considered, interannual variability of the mean sea level is essentially explained by interannual fluctuations in land water storage, with the largest contributions arising from tropical river basins"
Obviously the laymans eyeball is not as accurate as professional scientists calculations. If you want more information Google Scholar says Llovel has been cited 84 times. If you read the titles of the papers you can find one that answers your questions. Here is one I looked at. In the abstract it says all the fall in sea level in 2010-2011 is caused by land storage.
If you look at the intermediate level of the explaination of this myth here at SkS, there is a graph that shows the yearly seasonal variation of sea level in the Northern Hemisphere varies by about 60 mm and the Southern Hemisphere varies by about 30 mm. It seems reasonable to me that a change in rainfall could cause 10 mm yearly change for a short time when seasonal variation is so much larger.

Eclectic at 22:21 PM on 28 January 2020Sea level fell in 2010
Richieb @21 , I am not clear about the nature of your inquiry. Australia (the part that gets rained upon!) is about 3% of the world's land area . . . so presumably it was the other 140-ish million square kilometers receiving the bulk of the "missing" ocean water. Spread kinda thin, even allowing for local concentrations (see chart in OP).
Water runs off quickly and returns to the ocean, or soaks into the soil for a year or two ~ and eventually trickles back to the ocean, or evaporates and rains into the ocean. All part of the normal variation of things.
There doesn't seem to be any discrepancy requiring special explanation. There are always small ups and downs imposed on top of the continuing rise in sea level.

richieb1234 at 20:50 PM on 28 January 2020Sea level fell in 2010
Why did sea level fall in 2010?
This exchange in the Fall of 2011 presents a fascinating discussion of the relationship between global mean sea level and water transfer to land masses. Specifically, the apparent temporary downtrend in sea level around 2010 was purported to be explained at least partially by torrential rainfall in Australia and elsewhere. BUT the accumulation of rain on land was not nearly enough to account for the sea level drop. The discussion trails off in December 2011 without a resolution of the discrepancy. And the anthropogenic increase in sea level resumed its upward trend in 2012.
Was this discrepancy ever resolved? Does the discrepancy have implications regarding the accuracy annd relliability of satellite measurements? Is this related to the later downturn in sea level in the 2016 timeframe?
VR, richieb1234
Moderator Response:[DB] NASA has continued to track water motions across the planet, from alpine and ice sheet mass losses to the ocean and land impoundment changes over time, including torrential rains in the Amazon and Australia lowering global sea levels for a time. The overall trend is upward with the net effect that global sea level rise is accelerating in lockstep with accelerating ice sheet mass losses. NASA has a video on GRACE's 15-year mission tracking that, here.

One Planet Only Forever at 07:14 AM on 28 January 2020Doubling down: Researchers investigate compound climate risks
Hank,
Engineers I know share the understanding that any structure that does not meet code minimum design requirements is an unsafe structure based on the new code requirements.
The fact that increased levels of minimum requirements in a code update are not required to be applied to already built items, because of the cost, does not change the reality that the structure just meeting the older lower design standard is unacceptable based on the updated code. And in Canada any modification of an existing structure must include all modifications required to meet the current code requirements. And if the updated code requirements become significant enough then older buildings will be declared unable to continue to be used without upgrades.
So as I have tried to consistently say, increased risk of failure is the reality being created by rapid climate change. And any attempt to establish a design requirement in anticipation of rapid climate change faces the challenge of establishing certainty regarding how severe the future design requirements will become.

Bob @12 , you are superbly optimistic.
But the past 30 years are almost certainly going to be very different to the coming 30 years. Past and future changes in technology & social attitudes (and consequent economics) . . . ensure that the past cannot be extrapolated linearly into the future. Which makes it pointless to attempt to model a "re-run of history" from 1990.
If the Byzantine Empire had not fallen to the Turks . . . if Kaiser Wilhelm's father had not died prematurely . . . if Adolf Schicklgruber had died in childhood . . . if . . . if. So many broadbrush and "narrowbrush" events which might have been, and could have disrupted the course of history. And nowadays, the course of history is mutating ever faster.
No, the provision of data has no beneficial effect on the climate pseudo-skeptics. They do not "refute" ~ they have had decades of experience in unrelenting denial of reality. It is rare for any of them to change, short of death. They will continue to pervert (in their own minds) the logical scientific analysis of evidence. And when backed into a corner, they resort to playing the "political conspiracy" card. Really, Bob, it's all just a form of intellectual insanity.
And unless you can discover a cure for intellectual insanity . . . well then, your time would be better spent on more practical aims.

It seems we have the modelling capacity to predict the impact of what the current usuage of fossil fuel will have on CO2 concentrations in the atmosphere and subsequent effect on global temperature. That being the case, it should not be too difficult to predict the impact that would have occurred if fossil fuel use was halved in 1990. We could then compare any positive outcomes (e.g. temperature reduction) that would have resulted if we took that course of action versus what is in place today. Maybe we could also get a handle on any negative outcomes, e.g. reduced development in poorer countries or inconveniences in richer countries. Thus we could better determine how important it is to pursue reduction of fossil fuels use into the future. Surely that would provide "hard" data that any skeptics could not refute. It would also provide firm targets for emission reduction that would make a real difference as we go forward.

nigelj at 08:05 AM on 27 January 20202020 SkS Weekly Climate Change & Global Warming News Roundup #4
Bob Loblaw @8 now you are talking. That is exactly the problem.
In many places globally electricity generation is effectively a government run or privately run local monopoly, often with fossil fuels. Because its a monopoly they will try to lock out new alternatives that upset the prevailing comfortable arrangements. Customers have no choice.
In my country (and I believe in Texas) we have a different system, an electricty market system effectively run by the transmission lines company (which is a natural monopoly you can't change that). But the system is structured to prevent generating companies joining together to create a big monopoly, especially one that excludes any particular form of generation.
So the system is designed to provide customer choice between mutiple generating companies and to to ensure all generating options get a fair go including renewables. So we have generating companies with different mixes of types of generation, and customers can pick and choose.
A cap and trade scheme pushes up the prices of fossil fuels to encourages clean energy.

Doug:
THe thing that particularly galls me is how the fossil fuel industry (particularly in the U.S.) actively lobbies to place regulatory and financial hurdles in front of competitors via government intervention.
I wish that, as a consumer, I had freer access to alternatives, so that I could make more individual choices to avoid fossil fuels. The fossil fuel industry keeps its "competitive" advantage when it succeeds in reducing the availability of alternatives. Free market, my @$$.

Further to Nigel's remarks, a couple of nights ago this matter of producer vs. consumer culpability came up in conversation over dinner over in these here parts. My initial sour remark was that 90% of people blaming oil companies for our problems would be begging them to resume production after a week of cessation, were "they should just stop" actually to happen.
Remembering that I was in a dark mood, I amended my estimate to 60%.
What does distinguish oil majors is their concerted attempt to gaslight us— to reach into our heads and twist our grasp of reality— so as to preserve the money vector they enjoy. That's an offense against society unique to a select group. It's an act of calculated harm with effects similar to antisocial behavior covered in statutory law, even if no actual criminal code encompasses the transgression.

It is a fact that some people can and will be careless with fire, I myself have helped put out a bush fire caused by someone’s careless disposal of a cigarette. And it is a fact that some warped individuals do start fires intentionally, but as Nigel asked, so what? This is nothing new. If the NSW and Victoria forests hadn’t been so tinder dry from prolonged drought and sustained elevated temperatures the fires would not have been so wide spread, **regardless** of ignition source, a point conceded in the very opinion piece that Aleks linked to.
Nor would the fires have grown so quickly and widely from flying embers:
“Fire officials in New South Wales reported that embers were landing 30km (18 miles) ahead of the front on Tuesday – three times more than the usual distance.” https://www.bbc.com/news/world-australia-50383800And as for Aleks’ insinuation that the absence of thunderstorms precludes lightning strikes, as has been observed in previous fires, this year’s bushfires were so intense that they created their own weather which included dry lightning strikes.
By digging in Aleks shows again that he is incapable of grasping the difference between proximate and ultimate causation, which Phiippe just illustrated quite nicely.

A few months ago, someone had the same argument as Aleks. I pointed to the poster that the logic was flawed by comparing it to the following situation: when I get home in the evening I turn the light on flipping a switch and create a minor spark; if one day there has been a gas leak and the air/gas mixture has reached the right proportions in the house, my ordinary gesture will cause a devastating explosion. By that poster's logic, turning the light on would be the cause of the explosion.
-
nigelj at 06:41 AM on 26 January 2020Waking up to climate change | Australia's Bushfires
aleks @8, so what? What I mean is we all know fires are started for different reasons, basically lightening strikes, arson and accidents like discarded cigarettes. There is no evidence presented that these problems have grown significantly in recent years, and in this fire season. The fire services has said arson isn't looking like a significant factor this season.
What we know is hot dry conditions mean fires catch hold very easily and spread quickly and can burn large areas. Climate change is certainly causing hotter conditions. You need to explain how hotter conditions would not make bushfires worse, and I think it would defy all logic. Granted drought plays a huge part as well.
There's also evidence that climate change is increasing the length of the fire season.

"The companies that have contributed most to climate change"
These sorts of scapegoating views don't help much. The trouble with this is leads to finger pointing, where people will say "governments should do something about oil companies then". "The climate problem is nothing to do with me". Now this totally distracts attention from pushing for clean electricity grids and lifestyle changes.
And what can governmnets practically do about fossil fuel companies? They are legal entities so attempts to shut them down, or cap how much oil they are allowed to produce would require massively draconian policies and people would rightly be concerned about government abuse of power. And simply shutting the companies down would cause massive economic dislocations. Although I have to say its tempting.....
Concentrate on the things that could work and are compatible with a reasonably free society. Carbon taxes, cap and trade, subsidies, fuel efficiency rules etc but set at robust levels that make a real difference. its going to hurt a bit, but there will be multiple benefits.
Shame the oil companies if you want, and executives that put personal self interest above all other things.

nigelj at 05:14 AM on 26 January 2020How did climate change get so controversial?
UncleJeff @19
Ouch!
"Bad science reporting"
Yes sometimes, but its not the fault of warmists and scientists. Talk to the media about that one.
The media manage to sometimes get facts wrong, but are reasonably ok on the whole. They exaggerate parts of the climate problem sometimes, yet they also miss the genuinely serious aspects of the climate problem and this is actually a bigger reporting problem. They have false equivalency between both sides of the climate debate, because they are driven by trying to get people to turn the page.
"clean energy crony-capitalism"
Not sure what you mean, but I don't think you can include subsidies for clean energy in this category of crony capitalism. Crony capitalism is favours for industry that simply don't make sense in terms of the public good. Renewables are a public good. Fossil fuel subsidies would fit that definition of crony capitalism better.
"outdated stats in the political arena"
What outdated stats? The stats for 2019s temperatures have just been released and they are the third warmest on record, or something close to that.
"It also doesn't help that certain political factions have hitched their freight to the climate issue, arousing unneeded opposition."
Agree this is a problem. But we are a free society.
"Therefore, the alarmist camp would do well to .... actively discourage the overzealous etc from discrediting climate science via sloppy reporting, opportunism etc. "
Agreed. I do this including when people hugely exaggerate. But then I get labelled a denier for my efforts.

Philippe Chantreau at 04:57 AM on 26 January 2020How did climate change get so controversial?
UncleJeff, that's wishful thinking. Deniers have shown over and over their willingness to argue in the most blatant bad faith, against scientific realities that they often don't even understand. I have lived through the "carbonic snow in Antarctica" days, or the averaging of percentages without weighing made by prominent deniers at WUWT. I have seen the Soon & Baliunas fiasco, McIntyre&McKitrick junk. I found the standards of the deniers camp to be essentially non existent.
What you are saying is that there has to be a double standard: deniers can be completely full of it, deliberately lie, misrepresent, cherry pick, harass, misleadingly quote stolen e-mails, threaten opponents, but advocates of a livable future must be perfect, because even honest mistakes will be exploited by deniers. Unfortunately, you're right; that is the current state of this non-debate.

Aleks @5, you should read your own wikipedia reference. The huge areas burned in 1974 - 1975 were unused grasslands in central australia. No attempts were made to put them out. This is all very different from the current situation so its a meaningless comparison.
The area burned currently in NSW comprises forests, and totals 18,000 hectares, and this is higher than total areas burned in that state in the past (something aound 12,000 hectares), so this fire season is unprecedented in area burned for NSW.
-
Jim Eager at 04:25 AM on 26 January 2020Waking up to climate change | Australia's Bushfires
Aleks seems unable to discern the difference between ignition, the proximate cause of the fire, and the drying out of the bush by prolonged drought and elevated temperatures, without which ignition would not have been been so readily possible, making it the ultimate cause, regardless of the source of ignition. He is also quick to assign ignition to the random or deliberate actions of individuals, when in fact ignition in this case has overwhelmingly been the spreading of embers from one fire to cause many more fires.
-
aleks at 03:53 AM on 26 January 2020Waking up to climate change | Australia's Bushfires
High air temperature itself cannot be the cause of a fire, since the self-ignition temperature of dry wood is hardly lower than for paper (451оF). In the absence of thunderstorms at this time, it can be assumed that the fires were initiated by random or deliberate actions of individuals.
As for the "unprecedented" nature of the current fires, their history since 1851 is reflected in Wikipedia: https://en.wikipedia.org/wiki/Bushfires_in_Australia -
UncleJeff at 03:34 AM on 26 January 2020How did climate change get so controversial?
The article's thesis would be better supported if it included missteps made by the pro-crisis camp. Bad science reporting, clean energy crony-capitalism, outdated stats in the political arena etc all create paper targets for critics to aim at. It also doesn't help that certain political factions have hitched their freight to the climate issue, arousing unneeded opposition.
When well-meaning people with incomplete information see reporters, businesses and politicians slammed by newer or better facts, then the truth baby can get tossed out with the inaccuracy water. When they see historically unpalatable politics tied to all of the proposed solutions, even neutrals will get their hackles up.
Therefore, the alarmist camp would do well to first admit that not all arguments on its side are correct or helpful, and then actively discourage the overzealous etc from discrediting climate science via sloppy reporting, opportunism etc. The climate cause also isn't helped by political factions who exploit the climate crisis to advance side-causes not necessary to solve climate.

Nigel,
My thought as well except I was thinking "critical mass". The number of people frustrated with political inaction has reached a "critical mass" for getting out on the streets and protesting. But, of course, natural disasters, politicians coming out and voicing their ongoing denial of climate change in the face of these natural disasters, and the Greta Thunberg phenomenon are probably all factors behind the numbers reaching "critical mass".
I still have my reservations about Climate Adam's style, but horses for courses and whatever helps, but I can't help recommending Potholer again. His latest video is in response to the misinformation spread by the climate denying media about Australian bush fires. You might not want to watch 36 minutes of low key sarcasm though :)
https://www.youtube.com/watch?v=t0x46-enxsA
Whatever you may think of his style, he puts a great deal of work into those videos. In this latest video, he lists the 45 references. And it's had nearly 120,000 views, so it actually gets watched despite its length.

Ive read Hayeks book "A Road to Serfdom. Its really just a short treatise (thank god for that) arguing central planning of the soviet sort doesn't work because the planners can't possibly have enough information and computing power to process it (the book was back in the 1950s I think) and so free markets with decentralised private ownership work best. I've read quite good arguments that with our better knowledge today centrally planned economies could work as well as private markets, although I think it just goes too much against our natural instinct for private ownership. It would put a lot of trust in a very powerful government.
But I don't recall Hayek arguing that goverment had no role in economic affairs such as environmental regulation. Laissez faire economics like this has a poor record, eg early Victorian England. Economic growth was good but human suffering was terrible, until they slowly introduced child protection laws etcetera.
Scandinavia has a nice model that combines the best of free market capitalism and state control and ownership where this makes sense. There's a reasonable balance between freedom and control. I doubt we will do much better. Their economic and social data is good, and climate mitigation is quite good, and this is the ultimate test of the model. But I phlosophise too much...

"Globally, 2020 was 1.2°C above pre-industrial." Yes, but of course this is just an average. Australia was 1.52 degs c above even the 1960 - 1990 baseline in 2019. Canada was 1.7 degs c above this baseline.
www.bom.gov.au/climate/current/annual/aus/
But I believe these numbers are combined land / ocean data, (?) which would make Australia's land temperatures more than 1.52 degress above the baseline. Obviously this is where people live so its the more relevant number. But I'm not sure of what the 1.52 deg c number is, combined land and oceans, or just land.

This "new colour" can now be seen more often and longer. We have to act BEFORE all becomes irreversible!

Nic Palmer @ 4: " It does tend to be US types who most have that particularly extreme notion of 'freedom' though."

Eclectic at 20:42 PM on 24 January 2020Breathing contributes to CO2 buildup
Paul @131 ,
if you consult Wikipedia more closely, you will see that you have forgotten to add in a vastly greater living mass ~ plants , fungi, and various types of mono-cellular microbes.
They all respire CO2. And even though their metabolic rate is slower than warm-blooded humans, the sheer enormous size of their biomass means that they exude CO2 at a total rate enormously higher than humans.
So there's that.
Worth consideration !
I wonder why the expert scientists are not the slightest concerned about that?

PaulRittmann at 19:05 PM on 24 January 2020Breathing contributes to CO2 buildup
I believe breathing is a good thing and should not be interrupted for very long.
Let me summarize what seems to be relevant to people adding CO2 to the atmosphere. First, an adult produces about 1 kg CO2 each day, or 365 kg CO2 each year. Second, there are about 8 billion adults & children doing this. So how much CO2 does human respiration add each year? Here comes the math:
(8 billion people)*(50 kg/person average) = 0.4 GT live biomass
(365 kg CO2 per year)/(62 kg person) = 6 kg CO2 per year per kg live biomass
(0.4 GT)*(6 GT CO2/yr per GT live biomass) = 2.4 GT CO2 per year
For comparison, motor vehicles generate about 3 GT CO2 per year. All fossil fuels (& cement making) generate maybe 40 GT CO2 per year. It looks to me like respiration should not be discounted or ignored. Especially when livestock, earthworms, and marine critters are added.
From what I saw in Wikipedia on Biomass, the total livestock mass is about 0.7 GT. Also, the total for ants, worms, and termites is maybe 7 GT. Marine adds 2 GT. All these are rough estimates, so the total is roughly 10 GT living biomass.
If all the living things generate CO2 at the same rate we do, then the total respiration rate is 60 GT CO2 per year. This exceeds all the fossil fuels & cement production.
In conclusion, I'd say respiration is a significant source of CO2.
Moderator Response:[DB] Scientists know through due diligence that the rise in atmospheric concentration of CO2 is from the human combustion of fossil fuels due to the unique and characteristic isotopic nature of that rise and because it occurs in lockstep with the decline in atmospheric oxygen levels. Because they've done the research demonstrating both.

PS @16. Here is how the Victorian Government has ignored the Black Saturday Royal Commission recommendation of 5% control burned each year up from the then current 2%.
www.abc.net.au/news/2019-02-07/black-saturday-fire-fuel-threat-planned-burns-needed/10787050
"In the past three seasons, the number of hectares burned nosedived from 185,000 down to 65,000."

nigelj at 17:30 PM on 24 January 2020How did climate change get so controversial?
Nick Palmer says " If the world had perfect information about the actual rigidly defined results and timescales of climate policies and the definite results if such policies were not employed, I think it would be very easy for the people of the world to decide what to do"
Yes, but I'm inclined to think plenty of people would still kick the can down the road and have a big party and to hell with the climate problem. There is nothing to suggest market economics and the invisible hand will lead to sensible environmental outcomes. The market works reasonably well to allocate resources, and encourage innovation and as a mechanism to avoid the problem of dictatorships and communism. That's all it really does. It can't replace sensible government functions. It can't fix every problem. And I'm a fan of free markets in a general sense, but I'm not blinkered about their limitations.
Imho looking after the environment is a complicated value judgement sort of thing that requires a set of laws, or more informal agreements and a lot of complicated trade offs, and analysis, although a lot of its commonsense as well. Personally I like the Obama doctrine "dont do stupid stuff" :)

JohnMashey @14 , thanks for that. The picture has been bleak for a long time.
Nick Palmer @13 , it would become a can of worms, to properly define economics (just as it would, to properly define democracy ).
The modern "science" of economics (think Friedman . . . and worse) tends to dismiss externalities and the bigger picture in general. As you are well aware, I'm sure. To a large degree it is divorced from evolutionary darwinism (except social-darwinism !!) and from human neurology . . . and from human compassion.
I am too cynical to accept your "perfect information" hypothesis. The basic problem is that the selfishness aspect of our human nature does override our altruistic tendencies, when we live in the anonymous conglomerates of mega-cities and mega-towns. The healthy sense of community gets diminished.
The old "Invisible Hand" concept worked well at the village level of long ago, but - as history shows us - works poorly in more modern circumstances. Today, the real Invisible Hand is cartels and Facebook and the likes of Cambridge Analytica . . . and insider-trading . . . and the newer forms of the Tragedy of the Commons.
Yet it is the standard economist "religion" that the bus will follow the best road if we push down on the accelerator and take our hands off the steering wheel.
That's a crazy religion. Realistically, we should take a giant lesson from the control systems within the biological creatures that have survived & flourished over millions of years. ~But that would go against the entrenched religious dogma of capitalism & communism & and other -isms.
Ah, getting too philosophical. Sorry.

Dark Money: Excellent suggestion for all! Jane is one of the very best investigative journalists in US, honest, fearless and a relentless digger and teller of truth.
As it happens, I've been looking at Kochs for a long time: search for Koch in Crescendo to Climategate Cacophony(2010)
or look especially at p.47 and then pp.93-95, that shows which funders give money to which organizations that do climate denial. p.96 has summaries: the 3 main Koch-related foundations (there's a 4th, but small) gave much more than Exxon. Of course, at that point I didn't know about the Kochs+allies' money anonymizer DONORS TRUST/CAPITAL FUND, which I only figured out in early 2012, updated later in Fakery 2. See pp.68-76. See also Robert Brulle's more extensive research, summarized in Study Details Dark Money Flowing to Climate Science Denial(2013). Over time, Koch direct funding down, DONORS way up as seen in graph there. Charles Koch always hated having to report recipients of money from his private foundations. Lately, Donor Advised Funds are increasingly used by some to obscure what they're doing, i.e., N donors give money to a DAF, which then writes the checks, but without identifying the sources. Occasionally one can figure that out, but only with luck.

Eclectic at 14:01 PM on 24 January 2020Animal agriculture and eating meat are the biggest causes of global warming
Barb @46 , please don't feel any heat (metaphorically speaking). You are most welcome to post.
My principal objection to your initial comments was that you urged climate scientists to expand their advocacy into the simultaneous advocacy of veganism. IMO, such action by them (or by anyone linking climate matters and veganism) would be wrong because counterproductive (to the point of self-sabotage) in the urgent tackling of AGW.
Your economic arguments are good ~ their main weakness being because based on the assumption that the current methods of "meat production" would continue at present levels (or higher, worldwide). For all sorts of reasons - some touched on, earlier - it is likely that "farm meat" consumption per capita will decline in the latter half of this century. But it need not go down to zero, to be ecologically sound.
Your health/medical arguments are weak in their science ~ but they are a "Motivated Reasoning" consequence of your veganism . . . and there would be little point in me firing torpedoes at them. Plus, it would be off-topic.
I shall submerge to 20 fathoms, and switch to electric motors.

Markoh at 13:23 PM on 24 January 2020Australia's heat and bushfires are signs of fundamental shifts in its climate
John @15 my understanding is that bushfires do not count towards a country's emission commitments, only controlled burns add to the Paris commitment. Hence the reluctance by states to do controlled burns.
Moderator Response:[PS] what is your evidence reluctance by states to do back controlled burns? Seems to be contradicted in this factcheck.
A reminder yet again to back assertions with references.
