The need for positive action

with 2 comments

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:
http://www.carbonbrief.org/blog/2015/06/g7-leaders-target-zero-carbon-economy/

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).

Why is the G7 still ignoring what scientists and economists say?

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:

Polite suggestion for Bjorn Lomborg and Tony Abbott

with 6 comments

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.

Peak carbon by 2025 or mass extinction of species

with 11 comments

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.

Myles Allen's graph of 1 trillion tonne emissions curves

Extract of paper presented at ‘4 Degrees and Beyond’ conference (2009)

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).

The argument for leaving fossil fuels in the ground is overwhelming

with 4 comments

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:

The argument for divesting from fossil fuels is becoming overwhelming (Guardian website, 16 March 2015)

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:

The argument for divesting from fossil fuels is becoming overwhelming (Guardian website, 16 March 2015)

Footnote: See a landmark report by the Lancet and University College London, which concluded in 2009: “Climate change is the biggest global health threat of the 21st century.”

It could never happen here (could it?)

As reported on the DeSmog blog, in Florida, acceptance of climate science has been equated with mental illness…

Barton Bibler is a long-time DEP employee who now serves as Land Management Plan Coordinator in its Division of State Lands. He attended a Florida Coastal Managers Forum on February 27, 2015 at which climate change and sea-level rise were discussed among a mix of public attendees. Mr. Bibler’s official notes on this meeting reflected all of that discussion. He was directed to remove any hot button issues, especially explicit references to climate change, and then was given a letter of reprimand for supposedly misrepresenting that the “official meeting agenda included climate change.”

As he was given the reprimand on March 9th, Mr. Bibler was told to not return to work for two days which would be charged against his personal leave time. Two days later he received a “Medical Release Form” requiring that his doctor supply the DEP with an evaluation of unspecified “medical condition and behavior” issues before being allowed to return to work.

Read the whole story at DeSmog blog.

Addendum (1800 GMT, 27 March 2015):
Having compiled it, I think my response to Catweazle (below) is worth adding here. This is because it includes references to useful sources that validate acceptance of climate science as objective and its denial as ideological, as follows:

I accept that hydrocarbons are essential to modern life (as demonstrated by the way the oil price affects the price of almost every commodity money can buy). However, the IEA, IMF and OECD all accept that those who have a genuine choice to divest from fossil fuels should do so wherever possible.
http://www.oecd.org/site/tadffss/reports-to-g20-fossil-fuel-subsidies.htm

Sadly, even this agreement is based on a significant underestimate of the costs of futher delay in taking effective action to mitigate and/or adapt to anthropogenic climate disruption (ACD).
http://www.iied.org/costs-adapting-climate-change-significantly-under-estimated

If the disputation of ACD were based on truly objective and scientific scepticism it would not have such a clear ideological and political bias (Painter, 2011).

Merchants of Doubt need to do the math

with 5 comments

A feature-length documentary, based on the content of the Merchants of Doubt book by Naomi Oreskes and Erik Conway, went on general release at movie theatres in the USA this weekend.

As Desmogbog.com points out, it has already attracted the attention of an odd mixture of ideologically-motivated deniers of the reality of anthropogenic climate disruption.

I say “odd” because, as per the above link, those who prefer to see climate science as a conspiracy to raise taxes (and install worldwide Communist government via the united Nations, etc.) include both longstanding disputers of inconvenient science like Fred Singer (who questions whether the movie is defamatory) and self-confessed non-experts like James Delingpole.

Both of the above would have done well to watch a recent BBC Four (television) programme – Climate Change by Numbers. In contrast to just about every other programme about climate change that you might have seen, this one is presented by three mathematicians. A 30-second trailer is inserted below but, if you have not seen the full 74-minute programme (opens in a new window), I really would recommend it.

The programme focuses on three numbers:
— 0.85 Celsius – the rise in average global surface temperatures since the 1880s.
— 95% – the certainty of the scientific community that this is primarily human-caused.
— 1 trillion tonnes – humanity’s carbon budget to avoid 0.85 increasing to 2 Celsius.

Along the way, the programme highlights the early work of Svante Arrhenius – who determined that a halving of atmospheric CO2 could cause a 4 Celsius drop in temperature (and therefore that a doubling of CO2 will cause a 4 Celsius rise).

With regard to the accuracy of computer models, the programme highlights the way in which this has been proven by their ability to predict the cooling effects of large volcanic eruptions.

With regard to our carbon budget, the programme highlights the fact that humanity has already burnt 0.5 trillion tonnes and, unless radical changes are made to global trends, will burn the remaining 0.5 trillion tonnes within 30 years. It also points out that, as ongoing events might well suggest, even 2 Celsius could have severe and pervasive impacts (as the IPCC described them last year).

All very inconvenient for libertarians everywhere, I guess.

Addendum (17 March 2015):
The final third of the programme includes a discussion of ‘extreme value analysis’ (EVA), which Wikipedia helpfully describes as “a branch of statistics… [that] seeks to assess… the probability of events that are more extreme than any previously observed”. Flood defences like the Woolwich Barrier on the Thames estuary were designed using EVA. However, crucially, EVA assumes that average parameter values do not change over time. Therefore, given that climate change invalidates this assumption, it is now accepted that London will need greater protection from flooding in the future. This is why I included a link to (my blog post about) the ‘Climate Departure’ reseach of Mora et al. (i.e. below), which estimates the regional variation in the date by which future climates will have departed from what has hitherto been considered normal.
