See the Tabbed Pages for links to video tutorials, and a linked list of post titles grouped by topic.

This blog is expressly directed to readers who do not have strong training or backgrounds in science, with the intent of helping them grasp the underpinnings of this important issue. I'm going to present an ongoing series of posts that will develop various aspects of the science of global warming, its causes and possible methods for minimizing its advance and overcoming at least partially its detrimental effects.

Each post will begin with a capsule summary. It will then proceed with captioned sections to amplify and justify the statements and conclusions of the summary. I'll present images and tables where helpful to develop a point, since "a picture is worth a thousand words".

The Will to Change: Oil Companies Should Embrace Renewable Energy

Summary: Exxon’s scientists conducted extensive research in the 1970’s and 1980’s showing that use of fossil fuels produces greenhouse gases that warm the planet.  These results were accepted by the company’s management.  By the 1990’s, however, the fossil fuel industry changed its message.  It began a campaign to plant doubts in the minds of the public about the reality of manmade global warming and its effects.

Although many large American companies have prospered because they embodied an optimistic culture, a “can-do” spirit, by the end of the 20th century the fossil fuel companies adopted a “won’t change” attitude.  They resisted the scientific reality of manmade global warming, seeking to continue their business model of producing fossil fuels to supply the world’s energy.

Yet objective climate science shows that continued atmospheric accumulation of greenhouse gases such as carbon dioxide will lead to large increases in the global average temperature.  In face of this threat the world needs to move rapidly toward a carbon-free energy economy.  The large fossil fuel companies can play a major role in this shift, were they to adopt a “can-do” spirit.  The technologies already exist, the labor market is waiting, and they have the resources to carry out this transformation while remaining profitable.

  

Exxon’s Own Research on Global Warming.  As the issue of manmade global warming gained prominence in recent decades, scientists at Exxon carried out research on the phenomenon in its own laboratories.   This program was extensive enough that it led to about 50 publications in peer-reviewed scientific journals.  An Exxon scientist involved in this work told his corporate superiors that their company should embark on measures that would reduce emissions of greenhouse gases (GHGs).   

By the end of the 1980s, however, the corporate view on warming reversed sides.  The company sought to raise doubts about the reality of global warming.  As the United Nations-sponsored negotiations leading to the Kyoto Protocol, limiting emissions from developed countries, came to fruition, Exxon and other fossil fuel companies opposed the treaty, undertaking extensive lobbying efforts.  When the time came to consider the Protocol in the U. S. Senate in 1997, the vote to take up the treaty for debate failed unanimously.

Promoting Doubt about Global Warming.  From that period to the present, fossil fuel companies have engaged in a campaign that seeks to raise questions about global warming in the minds of citizens, leading them to doubt its reality and especially of its manmade cause.  This tactic had previously been used advantageously by the tobacco industry in its struggle to dissociate smoking from its harmful effects on smokers’ health (Naomi Oreskes and Erik M. Conway, “Merchants of Doubt”, Bloomsbury Press, 2010).  Indeed, some of the same personalities, having seemingly authoritative backgrounds in science, appeared in both battles.  Such doubt results in reduced pressure for change such as abandoning the extraction of fossil fuels that emit carbon dioxide, an important GHG. 

“Can-Do” Optimism.  This writer pointed out in the preceding blog post that the optimistic, “can-do” spirit that drove the growth of the U. S. during the nineteenth and early twentieth centuries has faded somewhat.  Now, many powerful industries, including the fossil fuel industry, when faced with indisputable scientific evidence indicating that they should change their operations, resist stubbornly.  They do this by promoting doubts about the scientific findings in question, and by adopting “won’t change” attitudes. 

Simplified historical sketches are presented below of three large American corporations.  The first two are considered “can-do” companies here. They have confronted technological changes in their industries and adopted new business plans to adapt to them.   The third one is ExxonMobil.

International Business Machines (IBM) was founded in 1911 when three companies combined to form the Computing-Tabulating-Recording Company, IBM’s precursor.  The company wrote “[f]rom the beginning, IBM defines itself not by strategies or products—which range from commercial scales to punch card tabulators—but by forward-thinking culture and management practices…”.  This culture informed the company’s development of new apparatuses that, for example, contributed logistics enabling the Social Security Act of 1935, a major piece of anti-Great Depression policy, to function.  In the post-war years IBM expanded by developing electronic computers, which permitted it to become an important international company. In the following decade IBM responded to new challenges by expanding its mainframe computer systems, leading to five-fold growth in income.  From 1971 to 1992 it overhauled its business model to adapt to the growing trend toward personal computing, but even so confronted difficulties created largely by its own successes.  As use of the internet has expanded, IBM has moved away from hardware to provide software and computing services.

General Electric (GE) was founded in 1889 by Thomas Edison based on his electric lamps, electric generators and motors, and power distribution.  Over the years, it developed or acquired businesses such as radio broadcasting, railroad and aircraft locomotion, electronic computing, finance, and medical diagnostic technology.  The list of its acquisitions and divestments is extensive, and was responsive to the changing business environments the company’s operations encountered.  Finance, for example, was intended to provide funds for purchasing its products, but portions have been sold off in recent years.  Additionally, as an outgrowth of its generation technology, GE manufactures industrial-scale wind turbines.

ExxonMobil began operations shortly after oil was discovered in Pennsylvania in 1859.  John D. Rockefeller formed Standard Oil in 1870 to harvest the oil; at that time the principal refined product was kerosene.  The company grew rapidly, operating in many states and abroad, but was forced to break up its units by two antitrust decisions of the U. S. Supreme Court, in 1892 and again in 1911.  Nevertheless, the separate companies prospered and many recombined again to form a smaller number of Standard companies.  In this period, as the number of automobiles powered by internal combustion engines grew gasoline production surpassed that of kerosene. 

Over the following decades, the various Standard Oil companies focused on extracting petroleum, refining it to yield gasoline, and distributing it at retail.  They also produced lubricating oils, petrochemicals and other products as years passed.  A principal Standard Oil company adopted the brand “Esso” (pronouncing the letters “S” and “O”) in 1926, which was changed to Exxon in 1972.  Exxon merged with Mobil, itself another Standard Oil company, in 1999 to become ExxonMobil.  ExxonMobil is now the largest non-state producer of petroleum and its products in the world.

Exxon set up its Solar Power Corporation in 1973 to make solar photovoltaic cells.  After determining that solar would not become profitable until 2012 Exxon sold Solar Power off in 1984.  (Mobil also had a solar venture from 1974–1994.)  From 1970 to 1986 Exxon ran a nuclear fuel preparation company.  Wikipedia (as of August 2016) lists no other non-fossil fuel ventures for Exxon.

In 2002 ExxonMobil, General Electric and others formed the Global Climate and Energy Project at Stanford University to develop new energy technologies emitting greatly reduced greenhouse gas emissions.  It intended to invest more than US$200 million over 10 years.  As of 2015, 46 research institutions worldwide are participating.  In 2009 ExxonMobil and Synthetic Genomics Inc (SGI). began research in their algae biofuels program.  Unfortunately, the project did not provide positive results and ExxonMobil cut back its support severely in 2013.   The company also established an energy research program with the University of Texas (Austin) Energy Institute.

Two “Can-Do” companies.  IBM and GE are categorized here as “can-do” companies.  Their histories embody a spirit of optimism, confronting the challenges of changing times and overcoming them to continue as successful ventures with new products.  IBM especially had troubles, and is currently dealing with yet more rapid change in information technology.

Energy demand is high and increasing, especially in countries of the developing world.  As their economies grow, the need for energy supplies grows in pace with their economies.  Their populations are becoming more affluent, entering the middle classes.  The most populous developing countries are China and India, and their demand for energy has been growing dramatically in recent decades.  In addition, whereas China’s population is relatively stable, that of India is growing rapidly.  In many developing countries including India, energy demand is fed both by growth in economic activity and by increasing populations.  The world’s population, now more than 7 billion people, is expected to grow to 9 billion by about 2040.

The fossil fuel industry has not had to overcome industry-wide challenges in order to grow.  The long-term worldwide demand for fossil fuels has never been in doubt (barring a few short-term hiccups and the current decline in demand for coal in the U.S. and Europe).  Commercial pressures in this industry have come primarily from within to improve its core technologies, rather than from a need to reinvent the companies by formulating new business models.  The large size of this industry and the confidence that demand for its products would stretch indefinitely into the future has led to its seeming complacency. 

ExxonMobil is actively resisting change.  In order to continue defending the role of the industry in the global economy, ExxonMobil and other fossil fuel companies are digging in their heels, resisting pressures for change coming from the need to minimize further warming of our planet.  As outlined above their attitude is one of resisting change, and of mobilizing their considerable financial resources and political influence to create doubt and oppose the need for change.  This may be changing, however.  Six non-U.S. oil companies and ExxonMobil have recently endorsed a price on carbon.

Total accumulated GHGs dictate how much warming (on average) Earth will undergo.  As manmade carbon dioxide and other GHGs continue accumulating in the atmosphere, the projected further increase in global average temperature rises accordingly.  This is shown in a chart from the Fifth Assessment Report (2013) of the Intergovernmental Panel on Climate Change, below:

Dependence of the projected change in global average temperature from about 1870 to 2100 (vertical axis) on the total amount of manmade carbon dioxide (as the main GHG; horizontal axis) foreseen from four emission “scenarios”, starting in 1890.  Circles represent each decade.  BLACK, historical data to 2010.  DARK BLUE, LIGHT BLUE, ORANGE, and RED represent projections for successively less stringent limits on emissions, from almost complete of emissions by 2050 to no meaningful limitation at all.
Source: Intergovernmental Panel on Climate Change, Fifth Assessment Report http://www.climatechange2013.org/images/report/WG1AR5_SPM_FINAL.pdf


The graphic makes clear that the increase in the total accumulated manmade carbon dioxide concentration in the air governs the change in global average temperature.  Only by minimizing future emissions using the most stringent constraints possible (DARK BLUE line and dots in the chart) can humanity keep further increases in global average temperature as small as possible.

The fossil fuel industry needs rapidly to change its business model. In the 1970s-1980s Exxon understood the threat from global warming.  But by the end of the 20th century it and rest of the fossil fuel industry were sowing doubts about manmade global warming and resisting the need to change.  Even so, the reality shown in the image above is that continued extraction and burning of fossil fuels moves the world further along the trajectory of higher atmospheric carbon dioxide and higher global average temperature, to the detriment of all humanity. 
 
There is no avoiding the imperative to abandon further extraction, and to begin at the present time to decarbonize the world’s energy economy.  Many needed  technologies already exist, the labor force awaits the coming job opportunities, and the large international fossil fuel companies have the resources to undertake these changes.  What’s missing is the will to change their business models.  The world looks to them to adopt the “can-do” spirit that drives capitalism, leading to new sources of revenue and profit, by creating a decarbonized economy.

Sources and Content of Contrarian Communications about Climate Science

A rigorous computer-driven analysis of organizations producing documents and speeches deemed to express contrarian views on climate change, the texts of these documents, and energy companies providing funding to those organizations has been carried out.  Entities receiving funding are more closely connected to one another than are those not supported.  The entities most active in generating communication are highly influential in the contrarian movement.  Several contrarian topics, from energy industry-funded entities, were the subjects of communications that increased in number strongly in the years since about 2007 compared to those from nonsupported entities.  Entities receiving funding were more likely to have produced contrarian writings.  These findings provide some understanding of why public opinion in the U. S. is more dismissive of the findings of climate science than it is in other industrialized countries.
 

The United States Congress in recent times has opted against enacting national policies that would lower the annual rate of emission of greenhouse gases (GHGs), especially carbon dioxide (CO2).  We in the U. S. have already suffered significant damages and harms brought on by the effects of global warming.  These include fair weather ocean flooding and heat-driven droughts in the Midwest and Southwest.  Damage from extreme events has high costs for recovery which ultimately end up being paid by individuals directly, or indirectly due to higher taxes needed for the extra, unforeseen government services.  On the other hand, federal legislation to combat warming and its harms would recognize, and counteract, the increasingly significant role of human activities in the energy economy that result in higher GHG emissions. 

In a democratic republic such as the U. S. we idealize that our representatives are responsive to the positions taken by their constituents.  In reality, however, the American political system has long been accused of being in the thrall of powerful economic interests who contribute to the election campaigns of our Congresspersons.  Campaign support from the fossil fuel industry is a prime focus in such discussions.  This undercurrent, while widespread among the electorate, is difficult to prove.

Justin Farrell has recently published two reports on potential connections between funding from energy producers and public discourse.  Farrell’s interest is the pronounced polarization in policy discussions of climate change.  He points out that earlier work in this field has been conducted at an individualized level of inquiry.  In contrast, he has taken advantage of the power of contemporary computing power to analyze effects that funding contributions from the energy sector may have had on climate change discussions from 1993 to 2013 (see Details at the end of this post).  

In one article (Farrell (2015) Nature Climate Change, published online)  the author applies computational social science to analyze networks among individuals and organizations producing discourse promoting climate-contrarian points of view, as well as the effect that funding from two fossil fuel corporations have on the networks (see Details).   Organizations receiving funding from the corporations are more closely tied to one another with high significance, in a test of connectivity, than those that are not so funded.  The funded entities thus “have greater influence over flows of resources, communication, and the production of contrarian information.” 

The most important factor in this result is the very fact of being funded.  The funded entities achieve a higher level of similarity in phrasing and expression in news reports, to a very high level of statistical significance.  Power within the organizational network is not evenly distributed, but rather is highly centralized among that smaller group of organizations having ties to private sector entities.  In Farrell’s view, these “findings … help to explain why climate science rejection is so pronounced in the United States compared to other developed nations.”

In his second article (Farrell (2015) Proceedings of the [U.S.] National Academy of Sciences, published online) the author examined relationships among the contrarian organizations, their ties to the funders, and the effects of funding on the thematic material produced.  First, to a high degree of statistical significance, the “results suggest that organizations within the movement who made an effort to produce textual discourse about climate change are the most central to the movement itself, providing them more influence over the transfer of information.”  Other analyses yielded the topics prevalent in the document texts, established clustered relationships among the topics, and compared the time-dependent production of topics by funded entities vs. nonfunded entities.  Examples of timelines for the topics “CO2 Is Good” and “Climate Change is a Long-Term Cycle” are shown below.

The vertical axis indicates how much the topic was written about, expressed as a decimal fraction. The red line represents the prevalence of the topic in the texts of contrarian organizations who received money, and the black line represents the prevalence of the topic for contrarian organizations who did not receive money.

Importantly, energy corporate funding is seen to have influenced the extent of polarization in climate change writing over the 20 years ending 2013.  In particular, thematic content on topics such as “CO2 Is Good” and “Climate Change is a Long-Term Cycle” (left and right panels, respectively, in the graphic above), deemed polarizing and subject to debate, produced by funded organizations was far more prevalent in the last few years of this period, compared to content from nonsupported entities.

Farrell concludes that “corporate funding influences the actual language and
thematic content of polarizing discourse.”  Entities that received funding from the energy companies were more likely to have produced texts characterized as polarizing discourse on climate change than those not so funded.  He also concludes “organizations that received corporate funding were more likely to have written and disseminated contrarian texts”.

The author emphasizes that, because of the computationally large size and objective analytical approach using robust procedures (see Details), these findings are highly significant, confirming earlier but more poorly substantiated concepts on climate change knowledge and politics.
 

Discussion
 

Farrell has analyzed the interrelationships among sources of contrarian discourse that were identified by others, their contrarian writings, and the existence of funding from energy company sources (exemplified here by ExxonMobil and the Koch family foundations).  The period considered is from 1993 to 2013.  He finds statistically strong correlations between funding and the connectedness between sources of discourse, such that funded organizations wield considerable influence in establishing the frames of discussion.  Corporate funding affected the wording and overall themes of discussion on topics considered to be polarizing in the sense that the positions taken are either contrary to, or dubious in the face of, reality.   The author concludes that his characterizations help us understand the basis for the relatively high prevalence of rejection of climate science in the U. S., when compared with other industrialized countries of the world.

The energy companies studied by Farrell are representative of those in the energy industry more generally.  In a time of great ferment worldwide seeking to reduce GHG emissions to near zero, energy companies clearly have an interest in preserving the status quo, so that the demand for their products continues unconstrained.  Farrell’s work shows that in the U. S. the financial support provided by the two energy companies studied here correlates strongly with the written and verbal communications produced by the organizations receiving the funding.  These writings run contrary to the objective findings of the worldwide climate science community and the policies that these findings strongly suggest.

The nations of the world are coming to realize the need for a universal effort to limit bring annual emissions to very low levels by mid-century.  They, and their populations, have to resist the flow of contrarian writings and speeches.  The science underlying contemporary climate change is beyond questioning, and has reached the stage requiring concerted, meaningful actions.  Contrarian communication from energy companies seeking to preserve “business as usual” must be resisted.
 

Details

 
In both articles (Farrell (2015) Nature Climate Change, published online; and Farrell (2015) Proceedings of the [U.S.] National Academy of Sciences, published online) the author used computational analysis first, of institutional and social network structure among individuals and organizations promoting climate contrarian points of view, and second, of analysis of texts containing climate contrarian viewpoints.  Farrell labeled “contrarian organizations [as] those identified by prior peer-reviewed research as overtly producing and promoting skepticism and doubt about scientific consensus on climate change”. 

The social network comprises 4,556 individuals connected to 164 organizations promoting contrarian viewpoints.  The organizations include think tanks, foundations, public relations firms, trade associations, and ad hoc groups. 

The texts were produced between 1993 and 2013, and include written and verbal content from the organizations identified, as well as from three major news outlets, the U. S. presidents and floor speeches in the Congress (40,785 documents containing over 39 million words).  They were analyzed computationally to produce contextually-driven topics using a process called Structural Topic Modeling, with sets of word stems identified for each topic.  This process was chosen because it permits consideration of document attributes such as the year written, or organizational attributes considered in the article such as corporate funding.  Importantly, the topics are not assigned manually in advance.   Rather, they are identified as a result of the self-learning features incorporated into the analysis.  In addition, Farrell considered whether the individuals or organizations had ties to energy industry entities.

Energy companies were restricted in the end to only ExxonMobil and the three Koch family foundations, the philanthropic organizations established by Koch Industries, because of the greater reliability of the information on contributions available for them.  (Koch Industries is a conglomerate active in the exploration, production, refining and distribution of petroleum and its products, among other endeavors.)
