I can barely believe it. One of Germany’s best-value exports (i.e. in the non-luxury end of the car market) has been caught faking the CO2 emission test data on its diesel cars in the USA (and, it has subsequently emerged, elsewhere).
Has it been doing the same in Europe? Is this the beginning of an international scandal similar to the rigging of financial markets in the City of London?
One thing is for sure, in putting profit before doing their bit to reduce the carbon footprint of their cars, I think the manufacturer should be re-branded:
US Senator James Inhofe (R-OK) is a climate change sceptic primarily because he believes God has promised not to flood the Earth again; and the rainbow in the sky tells him it must be true.
Such ideologically-driven wilful blindness is very dangerous. Indeed, most climate scientists agree that it threatens the future of most life on Earth.
Sadly, such ideological blindness is not unique to those foolish enough to believe the Earth was created in 6 days only 6,000 years ago. As Stephan Lewandowsky et al have pointed out, adherence to libertarian ideology and free market economics are strongly correlated with a rejection of the scientific consensus that humans are the primary cause of post-Industrial climate change. Pseudo-skeptics may have attempted to discredit this research but, they cannot refute the empirical evidence for the above correlation.
Indeed, in his book ‘Poles Apart: The international reporting of climate scepticism‘, James Painter provides ample evidence that climate change ‘scepticism’ is predominantly a feature of right-wing newspapers in English-speaking countries.
However, I digress from the story I want to tell…
It is no secret that stories of a global flood, like that of Noah and his Ark, are found in the earliest writings of numerous ancient civilisations around the World. Until yesterday, however, I had no idea what this might have to do with an abrupt but temporary global cooling event, known as the Younger Dryas, which occurred between 11,500 and 12,900 years ago.
This came to my attention yesterday morning while watching television, when the presenters of BBC Breakfast began interviewing a journalist I had never heard of before.
For at least 20 years, Graham Hancock has, apparently, being telling anyone that would listen that a comet impact in Antarctica about 12,000 years ago – and the sudden sea level rise it caused – wiped out most evidence of an advanced human civilisation that predates any of the others by about 5,000 years. In doing some research on this yesterday, I discovered that this was something that the Huffington Post had picked up on in May this year. However, digging a little deeper, I found that it is over 5 years since Hancock’s ‘smoking gun’ evidence was reported in the Scientific American magazine. It would therefore appear that Hancock is very good at self publicity and recycling old news.
Even so, I nearly choked on my breakfast when Hancock suggested that the Giant Sphinx at Gaza was not built by the Egyptians. He pointed out that the Sphinx appears much more weathered (by rainfall) than the in-situ stone on the pyramids around it. However, the real clincher for his argument was the fact that organic material – which can be carbon dated – found at the Gobekli Tepe site in Turkey is about 12,000 years old. This is significant because all other early civilisations – that left behind monumental architecture – are thought to date from no more than 7,000 ago.
This has long been a mystery that archaeologists could not explain, but which is explained by the comet impact.
However, again as a result of research I did yesterday, I was amazed to find out that suggesting a comet impact might explain the origins of the story of Noah’s Ark was not just Hancock’s idea. It is one that can be traced all the way back to Edmund Halley in 1694, as blogger Jason Colavito pointed out in his summary of Graham Hancock at the end of last year.
So, Graham Hancock has used his skills as an investigative journalist to pull together evidence from different spheres of science to solve the archaeological mystery of Gobekli Tepe. Therefore, given the amount of criticism he received 20 years ago for putting forward an idea with no supporting evidence, it is perhaps understandable that he is now making so much of the fact that the evidence has since been found.
However, even if the idea was not really his in the first place, I think this explanation for the Younger Dryas event is important because it highlights the fact that the vast majority of modern human civilisation is in danger of being wiped off the face of the Earth if large amounts of land-based ice slide into the sea.
Sadly, those who continue to dispute that this might happen – and/or assert that Antarctica is actually cooling – have picked a fight with science and history that they are bound to lose.
On what basis do I say this, you may well wonder. Well, for the record, here are two good reasons:
1. It is impossible to explain the totality of post-Industrial warming without acknowledging that the dominant factor is the 40% increase in atmospheric CO2 caused by the burning of fossil fuels (see also Fig 5 in Hansen et al 2007 below).
2. Although the interior of Antarctica may be cooling – and the sea ice around it may not be shrinking because of the huge expanse of the surrounding Southern Ocean – the West Antarctic Ice Sheet and Antarctic peninsula are amongst the fastest-warming places on the planet.
To conclude, I can do no better than to refer, once again, to the six reasons put forward by the formerly-sceptical economist William D. Nordhaus as to ‘Why the global Warming Skeptics are Wrong‘.
10 Sept 2015 (15:00 BST): With apologies for any confusion caused, this blog post has now been edited to remove repetition and ambiguity resulting from my hasty/poor proof-reading of the original.
I know this is very late but, it is such significant moment, I feel I must comment on the recent decision of Lancashire County Council to refuse to allow fracking to proceed in their county.
Never mind that their decision was primarily the result of NIMBYism… spurious worries about earth tremors; slightly-less spurious worries about groundwater contamination; and probably-valid worries about methane escaping into overlying aquifers (rather than being sucked out of the ground)… this was a great result for anti-fracking campaigners all around the world.
This decision sets an important precedent that I hope will not be overturned by the inevitable appeal by Cuadrilla; and/or over-ruled by the same national government that has promoted the cause of NIMBYism when it comes to opposing onshore wind turbines and solar farms.
Our supposedly “greenest government ever” could and should therefore be decried as hypocritical if they try and go against the wishes of local people in Lancashire.
Long-standing readers of this blog, written as it is by someone with a geological and hydrogeological background, may recall some of my previous posts on the subject of fracking. However, in a nutshell (or perhaps I should say “in a drill casing”), my opposition to fracking has hardened over time. Initially, my opposition was based on the same logical grounds as that against drilling for oil in the Arctic: Having established that burning fossil fuels is changing our climate, humans should now be trying to stop burning them as soon as possible. Now, however, I am also against it because it has been proven to give rise to methane contamination of groundwater; and because as little as 3% of the gas will actually be recoverable.
Given that China has now announced that it intends to make its carbon emissions peak within 15 years, can the G7 now be shamed into doing the same? We can but hope.
However, I digress from fracking (and Lancashire): In May this year, I was delighted by the appointment of Amber Rudd, as the new Climate Change Minister. This was partly because she is a woman. However, I was mainly pleased because, unlike so many totally ill-qualified, ‘sceptical’ non-experts — with Degrees in subjects like economics (Lord Lawson), Sociology (Benny Peiser), English (James Delingpole) or Classics (Christopher Monckton) — Amber Rudd accepts that the IPCC is not part of a global conspiracy to foist environmental alarmism upon a credulous world.
Amber Rudd, in common with the vast majority of relevant experts with a history of producing peer-reviewed scientific research, has concluded that the growing disruption to the Earth’s climate is being predominantly caused by the burning of fossil fuels in the last 200 years.
The only people now disputing this (as-near-as-science-ever-gets-to) certain fact are those with a vested interest in the perpetuation of the oil industry… and a handful of credulous (or wilfully blind) economists and journalists who perpetuate the myth that the science is uncertain.
Sadly, whether deliberately or otherwise, these very same people have, just as they did for the tobacco industry, succeeded in delaying for decades the effective regulation of an environmentally-damaging product.
That being the case, investment in fossil fuel companies should not only be seen as financially unwise; it should be seen as corporately irresponsible and socially unacceptable. We can but hope.
However, in the UK at least, there is of course the problem of the Energy Gap: The UK is being forced to close down it’s ‘dirty’ (i.e. high carbon intensity) coal-fired power stations. Unfortunately, the mix of low-carbon and renewable sources (i.e. wind, solar, tidal, and nuclear) — which even the fossil fuel executives of 50 years ago thought would have become dominant in the power-generation sector by now — is nowhere near to being in a position to replace coal. This leaves the UK importing huge amounts of liquefied natural gas (LNG).
As a quick aside, I would like to encourage all non-scientific types not to be intimidated by jargon. Take “carbon intensity” as an example. This is merely a reference to the number of carbon atoms in the product being burnt. As such, mining tar sands is ‘highest’ and burning methane is ‘lowest’.
Sadly, however, none of this changes the fact that burning any fossilised carbon increases the total amount of CO2 circulating within the biosphere, which is warming the planet as a result of the basic Laws of Physics. To make matters even worse extra atmospheric CO2 is slowly reducing the pH of seawater, which is making it harder for shellfish of all kinds to live and grow. This is a much more serious problem because they are the only means Nature has for removing excess carbon from the biosphere (by the processes that created the fossil fuels in the first place)…
Getting back to LNG: Clearly, it would be much better if the UK did not have to do this. However, if we accept the science, we do not have the luxury of taking decades to phase-out fossil fuel use.
China is right and the G7 should follow their lead.
As many economists have now pointed out, humanity needs to treat climate change as an existential threat — far more potent than any Earthbound terrorist group — that requires mobilisation of the military-industrial complex to minimise and/or adapt to it. Sadly, far too much of the military-industrial complex is still fighting a rear-guard action to perpetuate its own existence — rather than on trying to safeguard the habitability of planet Earth for future generations.
World-famous film director, James Cameron, might well have cited the ill-fated MS Titanic as an analogy for humanity today. However, I am sure we would all rather that money would be invested in minimising climate change; rather than on constructing Elysium.
We can but hope.
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:
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.
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).
