Why Are Climate Scientists Ignoring Peak Oil and Coal?

9 02 2014

While looking for evidence of whether Kevin Anderson realises we have problems with resources constraints, I found the below article (written three years ago mind you) which goes some way towards explaining why Climate Scientists are ignoring Peak Oil and Coal……

Climate scientists often make assumptions about large-scale growth in resource extraction without thoroughly referring to relevant studies in other disciplines. This is partially understandable given that they are not economists or political scientists. Yet I believe it is cause for concern.

While criticising the pervasive obsession with infinite growth of our political and economic institutions, it appears that many (albeit not all) climate scientists hold the belief that human ingenuity will somehow substitute declining oil with different forms of natural-gas, liquefied-coal, shale gas, and other carbon fuels at prices that can sustain growth.

For example, at the Cancun climate summit there was a paper by Professor Kevin Anderson that stated that “the only way to reduce global emissions enough, while allowing the poor nations to continue to grow, is to halt economic growth in the rich world over the next twenty years. There is compelling evidence that economic growth has already reached its global peak and that any strong return to growth (manifested by countries in the OECD or emerging economies such as China or India) will be met by a wall of triple-digit oil prices triggering another economic collapse. Continuing economic growth will also depend heavily on heavy fossil fuels, such as coal.

However, according to a study by Tadeusz W. Patzek and Gregory D. Croft, the world could also face peak coal in 2011, after which “the production rates of coal and CO2 decline, reaching 1990 levels by the year 2037″.

This estimate of the peak is early compared to other studies predicting peaks over the next few decades, but the report authors claim that this is because the world will seek to consume the highest-quality and most accessible coal first and leave the less energy-dense and least accessible coal to burn later (and most likely only for certain critical economic/military sectors).

The crucial point is that all our theoretically large supplies will not become economically viable because of a lower energy return on energy invested (or EROEI).  This will ultimately have repercussions for economic growth and affordable prices.

A piece written by Uppsala University physics professor Kjell Aleklett also criticizes the level of economic awareness of Intergovernmental Panel on Climate Change (IPCC) scientists with respect to coal.

“Our conclusion is that the assumptions of coal use that the IPCC recommended that climate researchers refer to in calculating their future horror scenarios are completely unrealistic. The question is why at all these gigantic volumes of carbon dioxide emission are to be found among the possible scenarios. The IPCC bears a great responsibility for the fact that thousands of climate researchers around the world have dedicated years of research to calculating temperature increases for scenarios that are completely unrealistic.”

The question is, how much impact will coal have on CO2 given how dependent the global economy is on oil? Dave Cohen of the Association for the Study of Peak Oil and Gas writes concerning the projected “business as usual” (BAU) scenario in a world of peak oil:

“In all BAU scenarios, it is presumed that energy technology (coal-to-liquids, biofuels, electric cars, any or all of these) will seamlessly step up to replace oil as the need arises. This assumption is not yet proven, and it appears to be tragically unrealistic.”

Cohen also mentions how CO2 emissions fell in the United States as a response to the recession, and they also fell in many industrialized nations in 2008 (albeit global emissions rose slightly overall due to Chinese and Indian growth), but with a global fall being confirmed for 2009.

[NOTE: they have significantly risen since 2009…]

Importantly, any significant prospect of economic growth is likely to trigger another oil price-hike and another recession with its associated emissions declines. Obviously though, the emission declines are nowhere near enough to prevent growth in overall CO2 concentration in the atmosphere.

Growth misunderstandings

Looking at the predictions of climate scientists, we see certain assumptions about growth without factoring in the economic impacts that occurred as a result of the 2007-08 recession. For example, Climate Progress’s Joseph Romm reports that “[c]onsequently, and with tentative signs of global emissions returning to their earlier levels of growth, 2010 represents a political tipping point.”

It is hard to tell when such strong growth will occur once more. But what seems clear is that any strong increase in demand will quickly tell us that we are at the end of growth — particularly when we have a global derivatives debt that is almost 20 times the size of the world economy. These derivatives are basically a complex form of financial gambling and future risk-taking. They are part of our hugely problematic debt-based money system which seemingly insists on infinite growth; a perverse concept which violates the limits of our biosphere.

So, are most climate scientists aware that the world has likely hit the limits to industrial economic growth already? It seems that global warming scenarios are based around assumptions of continuing emissions growth facilitated by a world where political, monetary, and energy systems are not in a state of turmoil. Romm makes the following assumptions:

“We’re at about 30 billion tons of carbon dioxide emissions a year — and notwithstanding the global economic slowdown, probably poised to rise 2% per year (the exact future growth rate is quite hard to project because it depends so much on what China does and how quickly peak oil kicks in). We have to average below 18 billion tons (below 5 GtC) a year for the entire century if we’re going to stabilize at 450 ppm (see “Nature publishes my climate analysis and solution“). We need to peak around 2015 to 2020 at the latest, then drop at least 60% by 2050 to at most 15 billion tons (4 billion tons of carbon), and then go to near zero net carbon emissions by 2100.”

We now know that the IEA has admitted that conventional crude reached its all-time peak in 2006. In their 2010 report they state the following:

“Crude oil output reaches an undulating plateau of around 68-69 mb/d [million barrels per day] by 2020, but never regains its all-time peak of 70 mb/d reached in 2006, while production of natural gas liquids (NGL) and unconventional oil grows quickly.”

A German think-tank also stated a few years ago that conventional crude oil peaked in 2006.  And, when considering “unconventional” liquid-fuels as a possible measure to alleviate the impact of the peak in conventional crude, it is important to realise that there is no real evidence to suggest that  these  alternatives (such as Canada’s tar sands) can fill the gap at prices that we can afford to burn.

Facing reality

Perhaps, it is worth highlighting here that speculative assumptions leave much room for error when it comes to mathematical modelling of a system that is highly dynamic and/or based on certain unknowns. Nevertheless, the current scientific predictions make it clear that we face a hostile climate in the coming decades. Many places are likely to become badly affected by higher temperatures with global average increases of between 2-2.8 degrees Celsius (assuming a rapid decline as depicted by the Hadley Centre).

However, the triggering of any climate feedback tipping points may depend on human economic activities that are helping to perpetuate these mechanisms; and these activities in turn are dependent on affordable oil prices in a global economy.

In the worst case, triple-digit oil prices and demand-destruction, political crises and wars, etc., will likely contract the GDP of industrial nations by a large amount. For example, a possible conflict with Iran could cause oil prices to soar rapidly. Also, the US Joint Forces Command 2010 report has warned that “surplus oil production capacity could entirely disappear” by 2012 as well as warning of potential energy-based conflicts. Unfortunately, these factors are not included in the climate change projections made by bodies like the IPCC.

In a world of peak oil and of escalating political volatility, the fears and worries expressed by climate change scientists (such as those at the recent Cancun summit) concerning catastrophic climate scenarios, are looking less justified. However, as discussed above, a rapid decline in CO2 output can still potentially lead to a 2.8ºC global average temperature increase by the end of this century. Although, one could argue that even this level of CO2 growth may not come to fruition if conflicts break out over energy resources in the next few decades. This could end up forcing governments to ration energy to be used only for bare essentials.

In order for any energy system in the future to work, there must be an end to the “just-in-time” market inventory system that makes us very vulnerable to shortages. (The just-in-time system is one in which the materials needed for the manufacture of a good are delivered to the factory just as they are needed. This reduces in-process inventory and carrying costs, freeing up cash for other purposes.)

Better still, instead of waiting around for governments and businesses to move beyond their growth-fetishes, people can consider getting involved in the Transition movement as a way of empowering themselves in a world where large-scale economies can no longer operate.

How strange, I just mentioned in your comment section the other day, the one the only Dave Cohen and here you are quoting the Dave of yesteryear. Here is a link to the Dave of today: http://www.declineoftheempire.com/2013/05/chinese-demand-peak-oil-and-realism.html.
Because Dave Cohen thinks and functions on an higher level then the average Homo laeviculus: http://www.declineoftheempire.com/2011/09/homo-laeviculus-clueless-man.html. he has no problem admitting when he has got something wrong.
Mike, Dave continues to write his blog despite it having not natural constituency: http://www.declineoftheempire.com/2013/04/dote-has-no-natural-constituency.html. His is truly a voice crying in the wilderness.
Another realist you might consider familiarizing yourself with is Stephen Emmott. In his “Ten Billion” Emmott head of Computational Science at Microsoft Research state he is “not worried about running out of oil and gas”.
Oh, yes I agree with Cohen EROEI is the last refuge of Peak Oilers.
Because I do like you I will leave you with the end of the Oswald Spengler quote I brought to Dave Cohen attention:
“The fight against Nature is hopeless and yet — it will be fought out to the bitter end”. “Man and Technics” p. 45

Why did you not post my comments I left the other day pointing out that Dave Cohen has changed his views since 2009? Here again is the link:http://www.declineoftheempire.com/2013/05/chinese-demand-peak-oil-and-realism.html. I also pointed out that Stephen Emmott head of Computational Science in his “Ten Billion” also states that he is not worried about “running out of oil and gas”. Both Cohen and Emmott are realists. Both are will to follow the data. Dave Cohen in particular should be applauded for being one of those rare public commentators who is will to publicly admit he has changed his views. I fail to see why you are posting this out of stuff. It adds nothing the contemporary discussion and diminishes the quality of your blog.

Sorry, simple oversight…… first time commenters are moderated in an attempt to screen out spam, and I must’ve just forgotten to approve yours after reading it…… I’m only human too!

Hundreds disagree with you….. DTM is recording record traffic at the moment.
