I often used to tell people, “If you can’t say anything positive then don’t say anything at all!”.
When it comes to this blog, however, I have repeatedly failed to take my own advice.
I therefore think I may have to stop blogging unless or until I can be more positive.
In the meantime, I would encourage all those who can to make their voices heard by engaging in positive collective action and/or peaceful public protest.
In the UK, there is an opportunity to do this next week – on June 17 – and I do hope it remains peaceful.
For the record, however, I have also added an addendum to my last post, which includes this link to an attempt by The Carbon Brief to be positive about the G7’s latest statement of intent:
Sadly, it too makes sobering reading – highlighting the similarities with the [then] G8’s pronouncements in 2009 and the fact that the [now] G7 produce less than 20% of global CO2 emissions. I would therefore agree with former Australian prime minister, Kevin Rudd, who suggested recently that the larger G20 must drive the planned global climate deal.
Whatever happens, I hope we do not see further nefarious and/or criminal acts to prevent progress (e.g. such the entirely bogus ‘Climategate’ scandal in 2009).
Despite the scientific and economic consensus – that 80% of known fossil fuels must be left in the ground if humanity is to avoid allowing climate change to become unstoppable and irreversible (IEA, IMF, IPCC, OECD, etc.) – the best the G7 can do is propose that we stop burning fossil fuels by the end of the century…
If the BBC report of the second day of this week’s G7 Summit in Germany is to be believed, this may be due to more tangible fears of a Greek exit from the Euro-zone and/or emerging threats like Islamic State.
However, I suspect that our global politicians are simply unwilling or unable to face the reality that such a proposal – that humanity can take 85 years to wean itself off its hydrocarbon addiction – is not a strategy that a significant proportion of species on Earth are likely to survive…
But please don’t take my word for it, just Google “80% of species face extinction by climate change” and take a look at the results you get, like this one: One in six species faces extinction as a result of climate change (i.e. even 17% would be significant).
The above article, on The Conservation website, cites research recently published by the author, Mark Urban, in the Science journal; the abstract of which reads as follows:
Current predictions of extinction risks from climate change vary widely depending on the specific assumptions and geographic and taxonomic focus of each study. I synthesized published studies in order to estimate a global mean extinction rate and determine which factors contribute the greatest uncertainty to climate change–induced extinction risks. Results suggest that extinction risks will accelerate with future global temperatures, threatening up to one in six species under current policies. Extinction risks were highest in South America, Australia, and New Zealand, and risks did not vary by taxonomic group. Realistic assumptions about extinction debt and dispersal capacity substantially increased extinction risks. We urgently need to adopt strategies that limit further climate change if we are to avoid an acceleration of global extinctions.
Urban, M.C. (2015), ‘Accelerating extinction risk from climate change’, Science 348 (6234) pp.571-573
17% may be a lot less than 80% but, as this most recent synthesis of available research states, previous estimates of the risk “vary widely” and – given the complexity of ecological systems upon which we rely for food production (etc) – I think most biologists would agree that 17% is still very significant.
The scientific and economic consensus is that global CO2 emissions must peak within a decade in order to avoid a runaway greenhouse effect taking hold. Is failing to do this really a risk that humanity should be taking?
As the BBC has pointed out, the G7’s stance may well signal (to investors) that the end of fossil fuel era is approaching. However, whereas the G7’s mid-century target is for emissions to be cut 40-70% globally compared with 2010, the scientific and economic consensus makes the G7 appear reckless and/or complacent in suggesting that we can afford to burn fossil fuels at all past 2050.
Ultimately, I think the reason for humanity’s collective failure to address the urgency of the need for action on climate change comes down to psychology. After all, being in denial is cheaper than being in therapy.
Also worthy of note is this attempt by The Carbon Brief to be positive about the G7’s communique:
James Delingpole is the reason that I started blogging four years ago. (If this is news to you, please see Background.) I have therefore been drawn out of blogging hibernation by the fact that James’ name features on the winning exhibit of this year’s Anglia Ruskin Sustainability Art Prize.
The award-winning piece, by third year BA (Hons) Fine Art student Ian Wolter, is a supposed memorial inscribed with the names of a (hopefully) dying breed of individuals who – entirely illegitimately – claim to be climate change ‘sceptics’. That is to say, they claim to be ‘sceptical’ about the fact that humans are the primary cause of post-Industrial climate change.
Thus, I say “entirely illegitimately” because, as I have often said before, true ‘scepticism’ is the foundation of modern science: It is the reason modernity emerged from the mysticism of the Earth-centred Universe wherein the Roman Catholic Church attempted to hold back the progress of scientific enquiry.
True scepticism is the willingness to follow the evidence wherever it leads you. This is in stark contrast with supposed climate change ‘sceptics’ who choose to believe in scientific and/or political conspiracy theories – and reject all the evidence that conflicts with their ideological prejudices.
The prize-winning artwork includes the names of many of those that featured in my MA dissertation and my book – and who have featured on this blog (see ‘Peddlers of Doubt – monkeys or organ grinders’ (20 Feb 2012) and the posts that followed it).
Whereas the third Viscount – and former Lord – Christopher Monckton of Brenchley has described the artwork as a “death threat” , it is simply an optimistic assertion that the days of pseudo scepticism are numbered… As, indeed, was a recent post on the Yale [Unversity] Climate Connections website – entitled ‘Climate Warnings: Heard, but not Listened to’ (subtitled “With all that climate scientists have cautioned us about over the past three decades, we’ve forfeited all rights to say ‘nobody saw this coming'”), which began as follows:
The trouble is, of course, that these supposed sceptics refuse to accept the validity of any evidence that conflicts with what they want to believe (i.e. that humans are not primarily responsible for ongoing climate disruption): They are like the ‘Hear No Evil, See No Evil, Speak No Evil’ monkeys.
Twenty-seven years ago, when the world briefly awoke to the threats of global warming and tropical deforestation, scientists could only speculate on what changes might come in the future. Now, one need only look and observe.
The really crazy thing in all of this – and the primary reason for this blog post – is the length James Delingpole has gone to defend the self-confessed ideological basis of his rejection of the fact that climate change is an inevitable consequence of pumping 300 million years-worth off carbon into the atmosphere in about 300 years…
I say James Delingpole is “full of sheet” because of the two full pages that the Daily Mail newspaper allowed to cover with his Watermelon conspiracy theory – that dismisses all those who assert that human-caused climate change is a reality that must be faced as “climate zealots”.
Indeed, rather than accepting that the majority of relevantly-qualified scientists might actually be right, he prefers to dismiss them all as part of…
“…[a] powerful climate alarmist establishment — which includes everyone from the UN, Nasa and the Royal Society to the BBC and The Guardian [newspaper]…”
So, as I said, James is a self-confessed conspiracy theorist and – since he also admits to being completely incapable of – and uninterested in – assessing science for himself, I am not going to waste any more time refuting his cognitive dissonance.
I recently became aware of an article published on The Conversation website over a year ago, written by James Painter, author of Poles Apart: the reporting of international scepticism. The article, entitled Enough scientific certainty exists on climate change to challenge media sceptics (4 March 2014), is still worth reading if you haven’t seen it. Here is the crux of his argument:
So when sceptics stress the “nobody knows” narrative, they are misrepresenting the existence of any uncertainty at all as meaning that, for example, no action to reduce carbon emissions is necessary. It’s the nature of climate science that there are lots of uncertainties, but this doesn’t mean scientists know nothing, or are simply speculating.
However, it should be noted here that Painter uses the terms ‘scepticism’ and ‘sceptics’ solely for convenience: As is self-evident from what he writes, he does not accept this is an accurate term for those whose statements he analyses.
If you do not understand what I mean, perhaps the following will help:
Having read the above article, I decided to look at the comments, amongst which I found this from someone going by the name goldminor sanchez:
Here is another way to look at co2. Human emissions of co2 equal approximately 4% of the yearly release that goes into the atmosphere, the other 96% is natural. Co2 itself constitutes 400 parts per million of the atmosphere. So we have only added a tiny fraction of the total amount of a fractional gas. If the Earth was that sensitive to such a tiny change, then man and most life forms would have been wiped out many billions of years ago. That is something to consider.
This comment is so misleading, or simply betrays an astonishing level of scientific illiteracy, that I felt compelled to respond (even though over one year late). I also reported sanchez for being misleading.
Therefore, just in case his comment is removed, I have included it above. However, for ease of reference, here is my response (which explains what real sceptism is):
Here is yet another way to look at it… “Natural” CO2 is in constant circulation between the biosphere and the atmosphere (as is water), whereas “unnatural” CO2 has been out of circulation for millions of years. Thus, humans are well on the way to adding all this geospheric carbon back into the biosphere in just 300 years (thousands if not millions of times faster than the Earth can recycle it).
There have been 5 mass extinctions in geological history, all of which have resulted from climatic changes that occurred faster than organisms could adapt. Post-industrial change is about ten times faster than any “natural” change in geological history. That is why biologists have concluded that the 6th mass extinction is already underway.
To be sceptical is to accept that all our beliefs about reality are potentially falsifiable by contradictory evidence. Therefore, rejecting all evidence contrary to your antecedent beliefs (as young earth creationists do) is the opposite of being sceptical.
Given all of the above, it should be clear that disputing the primary human responsibility for ongoing climate change is not consistent with some very basic physics,* the totality of what we should learn from the Earth’s geological history, and the philosophical roots of genuine scepticism.
Australian Prime Minister Tony Abbott has announced that Australian taxpayers are now going to finance attempts to disprove the need to decarbonise our global power generation systems as fast as possible (see yesterday’s article on the Guardian website). However, Lomborg’s position is very confused (and confusing):
Lomborg: “Natural science has undeniably shown us that global warming is manmade and real. But just as undeniable is the economic science which makes it clear that a narrow focus on reducing carbon emissions could leave future generations with major costs, without major cuts to temperatures.”
Reality: Natural science has undeniably shown us that global warming is real and predominantly manmade. Just as undeniable is the economic assessment that any further delay in reducing carbon emissions will make it harder and more expensive to mitigate and/or adapt to increases in global temperatures.
My suggestion to both Lomborg and Abbott is that they should take time out to read the assessment of the formerly-skeptical Yale Professor of Economics, William D. Nordhaus:
‘Why the Global Warming Skeptics Are Wrong’ by William D. Nordhaus (2012).
Writing in response to an article in the Wall Street Journal signed by sixteen fossil fuel-funded ‘Merchants of doubt’ (including Richard Lindzen), Nordhaus began thus:
I have identified six key issues that are raised in the article, and I provide commentary about their substance and accuracy. They are:
— Is the planet in fact warming?
— Are human influences an important contributor to warming?
— Is carbon dioxide a pollutant?
— Are we seeing a regime of fear for skeptical climate scientists?
— Are the views of mainstream climate scientists driven primarily by the desire for financial gain?
— Is it true that more carbon dioxide and additional warming will be beneficial?
As I will indicate below, on each of these questions, the sixteen scientists provide incorrect or misleading answers. At a time when we need to clarify public confusions about the science and economics of climate change, they have muddied the waters. I will describe their mistakes and explain the findings of current climate science and economics…
Therefore, if anyone is inclined to think Bjorn Lomborg’s position on climate science has any credibility, I would suggest that they need to read (or if necessary re-read) what Nordhaus wrote over three years ago.
I have been looking back at some of my earliest posts on this blog; and have decided that now would be a good time to pull together some of the key points I have highlighted over the years – regarding anthropogenic climate disruption (ACD). I prefer the use of ‘ACD’ because it is far more accurate than more popular terms such as ‘climate change’ and ‘global warming’.
Firstly, then, ACD is an observed multi-decadal reality that cannot be explained by natual causes (i.e. sunspot cycles or volcanic eruptions, etc). See:
Comfortably numb is not good enough (3 September 2012).
The reason we keep getting double six (7 August 2012).
Secondly, climate science is not complicated or contentious, it is simply inconvenient for big business to accept. This is why the fossil fuel industry has spent the last 50 years trying to perpetuate the myths that it is both of these things. See:
Climate science in a nutshell – Part 1 (31 October 2011) (see also Part 2 that followed it).
Peddlers of doubt – monkeys or organ-grinders (20 Feb 2012).
Thirdly, and most importantly, the key thing to which the title of this post alludes: Research by a team at the University of Oxford published in 2009, which I first referenced in the first month of this blog’s existence (August 2011). This research shows that it is the total (i.e. cumulative) amount of fossilised carbon that we (have and will) put into the atmosphere that will determine the temperature change we will see over the next 50 years or so.
As per the Climate Change By Numbers programme on BBC4 Television, climate scientists are agreed that, in order to avoid irreversible and unsurvivable changes to the Earth’s climate, humans need to avoid adding 1 trillion tonnes of fossilised carbon (1000 GtC) to the atmosphere.
It therefore strikes me now, looking again at the above graph, that limiting global cumulative emissions of fossilised carbon to 1000 GtC will only be feasible if emissions peak within the next 10 years and the later the peak the more rapid the phase-out needs to be to keep the area under the graph the same (i.e. equivalent to 1000 GtC).
Governments around the world were very slow to react to the existential threat of the Ebola outbreak in West Africa last year. Evidence is now growing that, in taking over 25 years to take decisive action to minimise ACD, our governments have endangered the future survival of the vast majority of species on the planet (see biological and financial evidence below).
This is an avoidable tragedy. What our governments have lacked is a public mandate to act. I really hope this will soon emerge because, if it does not, evidence is growing that the sixth mass extinction of speies is already underway. See:
‘Has the Earth’s sixth mass extinction already arrived?’ (Nature, 471, 51–57, 3 March 2011).
That being the case, given the glacial pace at which progress has been made thus far, I think it is fair to say that humanity is rapidly running out of time to act. Furthermore, the problem is compunded by the fact that, under pressure from government-appointed scrutineers and/or sock-puppets of the fossil fuel industry, the UN/IPCC have consistently underestimated the costs of adapting to climate change. See:
‘Assessing the costs of adaptation to climate change’ (IIED, 2009).
I know I have been a bit slow but, I have now signed the Guardian’s new climate change petition.
Indeed, I was – and am – very pleased to see editor-in-chief Alan Rusbridger leading their campaign to phase-out institutional investment in the fossil fuel industry over the next five years, which includes an online petition, at:
Alan begins by pointing out that:
The world has much more coal, oil and gas in the ground than it can safely burn. That much is physics… Anyone studying the question with an open mind will almost certainly come to a similar conclusion: if we and our children are to have a reasonable chance of living stable and secure lives 30 or so years from now, according to one recent study 80% of the known coal reserves will have to stay underground, along with half the gas and a third of the oil reserves…
He then goes on to explain why divestment campaigns are working based on two arguments; one moral and the other financial.
The basis of the moral argument for divestment is summarised as follows:
The moral crusaders… see divestment from fossil fuels in much the same light as earlier campaigners saw the push to pull money out of tobacco, arms, apartheid South Africa – or even slavery. Most fossil fuel companies, they argue, have little concern for future generations. Of course, the companies are run by sentient men and women with children and grandchildren of their own. But the market pressures and [their duty to their shareholders] compel… [directors to pursue…] business as usual, no matter how incredible it may seem that they will be allowed to dig up all the climate-warming assets they own…
As such, there is a moral imperative to demand an end to the enormous subsidies that enable fossil fuel companies to pursue such an insanely short-sighted and ultimately self-destructive business strategy.
The pragmatic basis of the financial argument for divestment is summarised as follows:
If… the companies cannot, for the sake of the human race, be allowed to extract a great many of the assets they own, then many of those assets will in time become valueless. [Therefore, people…] managing endowments, pension funds and investment portfolios… will want to get their money out of these companies before the bubble bursts…
However, Alan makes it clear that:
The intention is not to bankrupt the companies, nor to promote overnight withdrawal from fossil fuels – that would not be possible or desirable… Divestment serves to delegitimise the business models of companies that are using investors’ money to search for yet more coal, oil and gas that can’t safely be burned. It is a small but crucial step in the economic transition away from a global economy run on fossil fuels.
Finally Alan explains why the Guardian‘s campaign is focussed on two organisations:
The Wellcome Trust handles a portfolio of more than £18bn and invests around £700m a year in science, the humanities, social science education and medical research. The Bill and Melinda Gates Foundation has an endowment of $43.5bn. Last year it gave away $3.9bn in grants towards health and sustainable development… Because both foundations are a) so progressive in their aims and actions and b) have human health and science at the heart of everything they do, we hope they, of all institutions, will see the force of the call for them to move their money out of a sector whose actions, if unchecked, could cause the most devastating harm to the health of billions [see footnote]… We understand that fund managers do not like to make sudden changes to their portfolios. So we ask that the Gates Foundation and Wellcome Trust commit now to divesting from the top 200 fossil fuel companies within five years… [and] immediately freeze any new investment in the same companies.
If you have not done so already, I would encourage all to read the full article and sign the petition at:
