Climate change: the fault of humanity?

The sixth report from the Intergovernmental Panel on Climate Change (IPCC) runs to nearly 4,000 pages.  The IPCC has tried to summarise its report as the ‘final opportunity’ to avoid climate catastrophe.  Its conclusions are not much changed since the previous publication in 2013, only more decisive this time.  The evidence is clear: we know the cause of global warming (mankind); we know how far the planet has warmed (~1C so far), we know how atmospheric CO2 concentrations have changed since pre-industrial times (+30%) and we know that warming that has shown up so far has been generated by historical pollution.  You have to go back several million years to even replicate what we have today.  During the Pilocene era (5.3-2.6 million years ago) the world had CO2 levels of 360-420ppm (vs. 415ppm now). 

In its summary for Policy makers, the IPCC states clearly that climate change and global warming is “unequivocally caused by human activities.” But can climate change be laid at the door of the whole of humanity or instead on that part of humanity that owns, controls and decides what happens to our future?  Sure, any society without the scientific knowledge would have exploited fossil fuels in order to generate energy for production, warmth and transport.  But would any society have gone on expanding fossil fuel exploration and production without controls to protect the environment and failed to look for alternative sources of energy that did not damage the planet, once it became clear that carbon emissions were doing just that? 

Indeed, we now know that scientists warned of the dangers decades ago.  Nuclear physicist Edward Teller warned the oil industry all the way back in 1959 that its product will end up having a catastrophic impact on human civilization.  The main fossil fuel companies like Exxon or BP knew what the consequences were, but chose to hide the evidence and do nothing – just like the tobacco companies over smoking.  The scientific evidence on carbon emissions damaging the planet, as presented in the IPCC report, is about as inconvertible as smoking in damaging health.  And yet little or nothing has been done, because the environment must not stand in the way of profitability. 

The culprit is not ‘humanity’ but industrial capitalism and its addiction to fossil fuels. At a personal level, in the last 25 years, it is the richest one percent of the world’s population mainly based in the Global North who were responsible for more than twice as much carbon pollution as the 3.1 billion people who made up the poorest half of humanity. A recent study found that the richest 10 percent of households use almost half (45 percent) of all the energy linked to land transport and three quarters of all energy linked to aviation. Transportation accounts for around a quarter of global emissions today, while SUVs were the second biggest driver of global carbon emissions growth between 2010 and 2018. But even more to the point, just 100 companies have been the source of more than 70% of the world’s greenhouse gas emissions since 1988, according to a new report. It’s big capital that is the polluter even more than the very rich.

The IPCC material distils a massive pool of data into a report that it hopes is irrefutable and alarming enough to force more radical change.  And it provides various scenarios on when global temperatures will reach the so-called Paris target of 1.5c degrees above average pre-industrial levels.  Its main scenario is called the Shared Socioeconomic Pathway (SSP1-1.9) scenario in, in which it is argued that if net carbon emissions are reduced, then the 1.5C target will be reached by 2040 at the latest, then breach the target up to 2060 before falling back to 1.4C by the end of the century. 

But this is the most optimistic of five scenarios on the pace and intensity of global warming in the 21st century and it’s bad enough!  The other scenarios are way bleaker, culminating in SSP5-8.5 which would see global temperatures rise 4.4C by 2100 and continuing upward thereafter (Inset 1).  There isn’t a scenario better than SSP1-1.9 and these are ignored by the IPCC.

Shared socioeconomic pathways

SSP1-1.9 is the most optimistic scenario, global CO2 emissions are cut to net zero by 2050. There is a huge shift to sustainable development, with well-being prioritised over pure economic growth.  Investments in education and health rise and inequality falls.  Extreme weather continues to increase in frequency, but the world avoids the worst impacts of climate change.  Global warming is kept to around 1.5C, stabilising around 1.4C by the end of the century.

SSP1-2.6 is the next-best scenario, global CO2 emissions fall but net zero is not reached until after 2050.  It assumes the same socioeconomic shifts as in SSP1-1.9 are met. But temperatures are left 1.8C higher by 2100.

SSP2-4.5 is the “middle of the road” scenario (i.e. the most likely).  CO2 emissions hover around current levels before starting to fall mid-century, but do not reach net-zero until nearer 2100.  Shifts towards a more sustainable economy and improvements in inequality follow historic trends.  Temperatures rise 2.7C by the end of the century.

SSP3-7.0 is one where emissions and temperatures continue to rise steadily, ending at roughly double current levels by 2100.  Countries become more competitive national and food security is prioritised.  Average temperatures rise by 3.6C.

SSP5-8.5 is the apocalyptic scenario. CO2 emissions roughly double by 2050.  The global economy continues to grow quickly by exploiting fossil fuels, lifestyles remain energy intensive and average global temperatures are 4.4C higher as we enter the 22nd century.

No probabilities are offered for any of these scenarios – just the hope and expectation that SSP1 will happen.  But the pace of emissions growth and temperature is already on a much faster trajectory.  The planet has already warmed 1.0-1.2C depending on how you want to measure it (current or 10-year average).  The trend is well established and is tending to surprise on the upside, not the downside.  Furthermore, the rate of change in atmospheric chemistry is unprecedented and continues to accelerate.

Even at 1.5oC, we will see sea level rises of between two and three metres. Instances of extreme heat will be around four times more likely. Heavy rainfall will be around 10 percent wetter and 1.5 times more likely to occur. Much of these changes are already irreversible, like the sea level rises, the melting of Arctic ice, and the warming and acidification of the oceans. Drastic reductions in emissions can stave off worse climate change, according to IPCC scientists, but will not return the world to the more moderate weather patterns of the past.

Even if we assume the SSP1-1.9 objectives can be met by 2050, cumulative global CO2 emissions would still be a third higher than the current 1.2trn tons of CO2 emitted since 1960.  That would push atmospheric CO2 beyond 500ppm, or 66% higher than where things stood in the pre-industrial period.  That pathway implies 1.8C of warming by 2050, not 1.5C.

The reality is that the IPCC’s very low emissions scenario is improbable: and the global temperature is likely to hit 1.5C much earlier than 2040 and reach a much higher level, even with the conditions of SSP1 in place, namely a 50% reduction in CO2 emissions by 2050.

More likely, global warming will reach around 1.8C by 2050 and 2.5C by the end of the century.  That means even more drought and flood events than currently forecast and so even more suffering and mounting economic losses from the mix – a loss in world GDP of 10-15% on current trajectories and double that in the poor Global South.

António Guterres, the secretary-general of the United Nations, responded to the report by taking aim at the fossil fuel industry: “This report must sound a death knell for coal and fossil fuels, before they destroy our planet.” But how? First and foremost, it’s not enough to end the government subsidies and financing of fossil fuel sectors by governments around the world (and that is still going on). Instead, there must be a global plan to phase out fossil fuel energy production. 

Left Democrat Robert Reich, former official in the Clinton administration, reckons the answer is to stop oil company lobbying, oil exploration, ban oil exports and make the oil companies pay compensation.  He stops short of public ownership.  But how can a really successful plan to stop global warming work unless the fossil fuel companies are brought into public ownership?  The energy industry needs to be integrated into a global plan to reduce emissions and expand superior renewable energy technology.  This means building renewable energy capacity of 10x the current utility base.  That is only possible through planned public investment that transfers the jobs in fossil fuel companies to green technology and environmental companies, where there will be many jobs.

Second, public investment is needed to develop the technologies of carbon extraction to reduce the existing stock of atmospheric emissions.  The IPCC says that going beyond net zero by removing large quantities of carbon from the atmosphere “might be able to reduce warming”, but carbon removal technologies “are not yet ready” to work at the scale that would be required, and most “have undesired side effects”.  In other words, private investment is failing to deliver on this so far.  

Decarbonizing the world economy is technically and financially feasible.  It would require committing approximately 2.5 percent of global GDP per year to investment spending in areas designed to improve energy efficiency standards across the board (buildings, automobiles, transportation systems, industrial production processes) and to massively expand the availability of clean energy sources for zero emissions to be realized by 2050. That cost is nothing compared to the loss of incomes, employment, lives and living conditions for millions ahead.

End fossil fuel production through public ownership and a global investment plan – this is just utopia, critics may say.  But then, market solutions of carbon pricing and taxation, as advocated by the IMF and the EU, are not going to work, even if implemented globally – and that is not going to happen.

There is less than three months before the delayed COP26 conference in Glasgow. The previous two major conferences produced nothing at all: COP15 in Copenhagen in 2009, and COP21 in 2015 (the Paris Agreement) only committed nations to voluntary emissions reductions targets that would lead to about 2.9oC of warming if achieved. Glasgow is shaping up to be no less of a failure.

  1. Absolutely amazing, that you can write a whole article about COP26 and not mention not 1, nor 2 but 3 elephants in the room, namely China or India or the rest of Southeast Asia, and their reliance on fossil fuels. Is that because it’s embarrassing that they are leading the world to doom in a handcart but cannot be mentioned because it doesn’t fit the woke narrative, But In India’s case they have a terrific answer “the West should reduce their emissions/capita to that of India. This is just one of the arguments that will sink COP26. The others are that China has no intention of doing anything else and instead has just opened up another 44 coal mines so that they can play catch up with the west in terms of emission/capita. The same argument is used by Bellisario when discussing his stewardship of the Amazon with Macron. “When you have the same tree density as we have then we can discuss Climate Change.” Of course, Macron is absolutely scared stiff of the Mouvement des gilets jaunes which started in response to Macron putting green taxes on diesel fuel. The same response is going to come from all the BRICS. “You first” will be the response to emissions reduction. As regards to the present incumbant of the White House the you really do see stupid. First he bans fracking on Federal Land and the uses Federal Statute to gooble all available land. Then he finds out that California which has already banned fracking, is running out of gas for consumers so he authorises purchese of gas from China, Russia. He then bans the Keystone pipeline but authorises the Nord Stream 2 pipeline from Russia to Germany who are already building new Thermal Power Stations using lignite. To achieve this they are strip mining, cutting down a 20,000 acre forest and leveling a village. Of course Boris wants to get in on the act and has now the quandarry of authorising the construction of a new mine in Cumbria and drilling for oil of the Scottish coast. But the mine is to produce coking coal, which according to the great and good is for the production of steel. According to the greens Sweden is already showing that Steel can be produced without generating CO2. Except that to replace coal requires 55 Trillion watt hours which is roughly what Swedens nuclear plants produce except that under pressure from the greens the Swedish government wants to close thaat down. So Sweden only produces 134 Trilionwatt hours and is now presented with a demand for 90 Terawatthours to replace nuclear and produce Carbon free steel. Oh and by 2030.These people cannot even read otherwise they would understand that Steel is produced using Carbon.

    Once upon a time before socialists morphed into Woke, they would support the mining idustry. In those days CO2 was considered a fertiliser and was responsible for greening the Safel and the Sahara. They looked forward to having a flying holiday once or twice a year and could purchase a diesel car which they could fill up in 3 minutes instead of 7 1/2 hours with EV’s. Socialists would also argue for a better standard of living unlike some who will tell us when we can use our carbon permits.

    1. One 1500 word post cannot cover everything but you are right about the emissions from those elephants precisely because they are elephants. Reliance on fossil fuels does not apply to the Global North alone but even more to the Global South.

      1. Hmmm… China may well lead the world in CO2 emissions but it has an enormous population (18% of the world total), whereas the USA, the 2nd HIGHEST producer of C02, has only 5% of the world’s population, so absolute numbers are meaningless without context. I might add, that the US military-industrial complex, is the single BIGGEST contributor to global meltdown. And at least China has (belatedly) woken up to the coming catastrophe (probably too late), are doing a damn sight more than the US is, which has actually gone backwards!

  2. Thank you for this interesting article (as always), but – please do not take this bad – I think that you are making yourself illusions. You talk about public ownership, green technology and environmental companies (with a lot of jobs), decarbonizing technologies, an end to all fossil fuel production. You hope that humanity will, at one point, understand that these market-based approaches do not work and that this realization will then, at last, produce the impetus for intelligent and efficient policy-making. Let’s hope that you are right, but I do not think so. It is not only fossil fuels, it is also agriculture, it is construction, it is electronics, there is hardly anything at all that you can think about that does not produce greenhouse emissions. It is not only emissions directly produced by humans, Earth itself produces ever increasing methane emissions due to the warming of the permafrost. How are we going to deal with all of that at the same time? You can assume that at one point the elephants and the global North will make a deal, but nothing points in that direction. The most important result of Copenhagen was that Obama succeeded in breaking up the solidarity between the countries of the global South. To implement the plans you are talking about, we need to win elections (something new) all over the globe or else we need a global revolution. Who is going to win these elections? Do you think that winning elections suffices? You can forget about the social democrats and over here, at least in my opinion, neither the left nor the greens have any idea about what to do. There is simply no plan whatsoever. Put on the radio and you hear what people talk about: it is about immigration, not climate change or macroeconomics. If you were right, I think, that we should see action today – not next year or the next decade, but today, after all the North pole is melting, the ice on the South pole is melting, the Greenland ice sheet is melting – two days ago by 8 miljard liter a day (enough to cover Florida with 5 cm of water) – the Gulf Stream is slowing down, the Amazon is a carbon emitter, several cities, countries and whole regions (such as the MINA or Peru, Bolivia and Columbia) are running out of water, in Siberia woods are burning on a surface bigger than the Netherlands and so on and so forth. I have heard the news today. What were they talking about? It was about immigration in this country with a population density of 25 people per square km. There is simply no hope left.

    1. Alexander Cockburn liked to play the role of contrarian, but unlike Cristopher Hitchens (who posed in Iraq’s Green Zone with Donald Rumfeld) Cockburn wasn’t posing. He raised a lot of static on the left by claiming not to believe in global warming. He even produced some interesting arguments, the most interesting of which was that if even the most dire predictions regarding global warming were true, they could only serve to divert attention from the immediate, do-able task at hand: ridding ourselves of the every day human disaster of the capitalist mode of (destructive) production.

    2. ‘’ To implement the plans you’re talking about, we need to win elections (something new) around the world or else we need a global revolution. ’’
      It will be the second option. About the year 2,040, according to some calculations. The modes of production are not overthrown with electoral ballots.

    3. Obama found that BRICS were making a deal behind his back and had to barge into the room. At CopenhagenChina did exactly what China always does. and destroyed any hope of 1.5 deg limit 11 years ago. Before we join the greens in chastising the BRIC countries as Greta does, we ought to remember that their scientists do not accept that CO2 increases are destroying the planet, Khabibullo Abdussamatov from the Russian Academy of Sciences promotes the same line as Willie Soon and Nir Shaviv, in that changes in the earth’s climate closely follows solar irradiance. But I expect they are all in the pay of fossil fuel companies.

    4. Absolutely! Just how do you turn around this runaway machine called global capitalism? It sounds naive but there’s only one way, and that’s one step at a time but it requires a coherent Left to lead it and unfortunately, such a creature no longer exists in precisely the countries that need one most, the Imperialist heartland, or G8 if you prefer. I also blame the environmental movement for its total lack of political understanding and its generally anti-socialist views.

  3. Again, a succinct summing up and I agree with almost everything in the comments. What is to be done, then? Dordi makes the point that the left with a green -socialist agenda is unlikely to win an election. I suggest we agitate to demand that all major decisions are decided by referenda (i.e a step towards real democracy, whereby citizens must live and die by their decisions) and the first demand be for a wartime-style economy, which had central government planning, state direction of industry and labour, severe rationing of raw materials and food, inroads into the rights of private property and taxation of the rich at 90%. Unfortunately, there are still those on the left who are unwilling to face up to climate change implications and still cling to the utopian vision of a post-capitalist world of a cornucopian abundance. As one leading socialist told me: people won’t like rationing, we as socialists need to get rid of low wages, and referenda raise issues that are too complicated for the working class! ‘There is simply no hope left.’ Alas, I tend to agree. At any rate, as socialists I think we now need to be drawing up a communist manifesto that addresses the question of how at least some modest part of humanity might survive capitalism. So many Marxists seem to be putting their heads in the sand. As a colleague of mine satirised what diverts so many from real issues:”Comrades, what are the political lessons that must be drawn from the recent discovery in Soviet archives that on the 23rd of September, 1923 Stalin had two eggs for breakfast, but Trotsky only one?”

  4. ‘’ To implement the plans you’re talking about, we need to win elections (something new) around the world or else we need a global revolution. ’’
    It will be the second option. About the year 2,040, according to some calculations.The modes of production are not demolished only with electoral ballots.

  5. The oil, coal and gas companies have to be seized without compensation. Their activities have to then be curtailed, with the workers given other useful environmental work, at public projects, with public monies. My fantasy is that the Board of Directors of each corporation will be arrested by a ‘people’s army’ and charged with criminal acts, and this has to happen in the very near future.

  6. Michael RE Your sea level rise. Here’s an Article from Nature Climate Change.

    Ocean Circulation Patterns Control Sea Levels
    Using measured data instead of climate model simulations, research published in Nature Climate Change shows natural factors, in particular large-scale ocean circulation patterns, drive changes in coastal sea levels.
    Large-scale ocean circulation patterns, and the causes and consequences of their shifts, are not well understood and thus are not accounted for well in climate models. The researchers involved in this study used a “global set of tide-gauge records over nine regions to analyze the relationship between coastal sea-level variability and open-ocean steric height [the vertical distance between two surfaces of prescribed pressure], related to density fluctuations.”
    On annual and decadal scales, sea-level variability follows open-ocean steric height variations along most coastlines, the research indicates.
    The scientists’ analysis of the large data set shows ocean circulation patterns alone account for 91 percent of coastal sea level change. Land subsidence or heaving (swelling or rising) and increased runoff from land (glaciers and channelized waterways) contributed modestly to coastal sea level changes as well. If this study is correct, these three factors alone account for almost all, if not all, change in coastal sea levels since 1960.
    “We find ocean circulation has dominated coastal sea-level budgets over the past six decades, reinforcing its importance in near-term predictions and coastal planning,” the authors write.

  7. We should socially own and democratically manage the wealth we produce and that which lies in natural resources so that we can have the power to distribute it on the basis of need and live in harmony with the Earth.

    But will we?

    Not if we don’t get on our bikes and push for it. I propose this for Australia. Of course, nobody will get behind it. Hey, but I tried:

    Political Programme of the Commonwealth Party
    We should socially own and democratically manage the wealth we produce and that which lies in natural resources so that we can have the power to distribute it on the basis of need and live in harmony with the Earth.

    That the emancipation of the productive class is that of all human beings without distinction of sex or so-called “racial difference”;
    That the producers can be free only when they are in possession of the means of production;
    That there are only two forms under which the means of production can belong to them
    The individual form which has never existed in a general state and which is increasingly eliminated by industrial progress;
    The collective form the material and intellectual elements of which are constituted by the very development of capitalist society;
    That this collective appropriation can arise only from the revolutionary action of the productive class – or workers – organized in a distinct political party;
    That a such an organisation must be pursued by all the means the working class has at its disposal including universal suffrage which will thus be transformed from the instrument of deception that it has been until now into an instrument of emancipation;
    The Australian workers, in adopting as the aim of their efforts the eventual political and economic expropriation of the capitalist class and the return to community of all the means of production so that the community can have the power to live in harmony with Nature and establish equal political power between all human beings, have decided, as a means of organisation and struggle, to enter the elections with the following immediate demands:
    1. All individuals, companies, banks, institutions and governments immediately halt all investments in fossil fuel exploration and extraction, immediately end all fossil fuel subsidies and immediately and completely divest from fossil fuels.
    2. Abolition of all laws over the press, meetings and associations.
    3. Suppression of the public debt.
    4. Legislated reduction of the working day to four hours with no cut in pay.
    5. Increase in funds allocated to the Age Pension with 55 being the age of eligibility.
    6. Abolition of all sales taxes and user fees replaced by a progressive tax on incomes beginning at $80,000 with an increase of the company tax to 49% (where it was in 1987).
    7. Construction of social housing with the goal of eliminating the waiting list within four years.
    8. Universal bulk billing for healthcare.
    9. Free public education through university and TAFE for all citizens.
    10. The Community to be master of its administration and its police.

    Professor Roberts lays out the humanoid’s dire dilemma….ends on a realistic note:

  9. There will be no transition from fossil fuels because there is no replacement for fossil fuels. Quitting oil means quitting mankind as we know it. It means going straight to the Middle Ages with the tiny inconvenience of a ten times larger population. But let’s don’t desperate, oil is quitting US: “Global conventional crude oil production peaked in 2008
    at 69.5 mb/d and has since fallen by around 2.5 mb/d.” (Page 45 of the Outlook 2018 by the International Energy Agency. Downloadable from

    1. There’s already been a transition as “renewables” in the US now equal or exceed the energy derived from coal. There’s no reason renewables can’t account for progressively larger portions of US energy supply, other than profitability and the weight of the “legacy value” of capital intensive hydrocarbon extraction. Petroleum provides for 98 percent of the energy consumed in transportation. That quantity can be radically reduced.

      Your stats on world production are a bit out of date: recent daily production of petroleum and other liquids globally exceeds 100 million barrels/day…unfortunately.

  10. Hi, Michael! I recently read your review of A. Shaikh’s book» Capitalism: Competition, Conflicts and Crises», where I saw that you wrote that A. Shaikh predicted the great recession in 2003, and you in 2005. Can you give links to specific works with these forecasts, please?

    1. My own forecast of the Great Recession was from my book The Great Recession p72. It says March 2006 but really was written earlier. Shaikh’s forecast can be found in his Capitalism book p749.

  11. @thesuninnclun

    Although I don’t like your tone, I actually agree with a lot of what you say.

    Like you, I’d bet that the BRICS will say exactly as you say: “You first”. They won’t be alone. That’s precisely what the psychopaths running Australia will say.

    But unlike you seem to believe, that is really what the west should do: “reduce their emissions/capita to that of India”.

    I don’t like that any more than you. It won’t be easy, much less pleasant. In fact, it will be terrible. But there is no way around. That is precisely what has to be done, or we’ll all go back to the stone age.

    Get this: emissions per capita (2019): US 15.52 tonnes; Bangladesh 0.66

    It’s not a matter of us being “woke”, it’s a matter of them having no emissions to reduce. That’s not that hard to understand, is it?
