The potential link between fossil fuel combustion at atmospheric temperature increase has been widely
discussed in scientific literature and academic texts relevant to the oil industry for more than a century.
The earth receives a constant stream of radiant energy from the sun. This solar radiation is critical to
maintaining planetary temperatures at a level which will support life. It has been equally critical to life
and to a stable human civilization, however, that a significant portion of the radiation the earth receives
from the sun is reflected back into space, thus ensuring that the planetary temperatures do not increase
uncontrollably. Beginning with the work of John Tyndall in 1859, it has been widely recognized that
certain “greenhouse gases”, such as carbon dioxide, make the earth’s atmosphere more opaque to that
reflected radiation, trapping energy that would otherwise be released back into space.2 At the same time,
scientists and industry experts alike have long recognized the simple and irrefutable fact that the
combustion of fossil fuels—including coal, oil, and natural gas—releases tremendous amounts of carbon
dioxide (CO2) into the atmosphere; and that, indeed, CO2 comprises the largest waste stream by far from
fossil fuel combustion processes.3
The proportion of carbon dioxide in the atmosphere has a strong positive correlation with planetary
temperatures. For more than a century, this relationship between carbon dioxide and planetary
temperatures has been routinely discussed in the scientific literature, including specialist journals and
textbooks for the geology and minerology communities, in the general and popular scientific press, and
even in newspaper reports.4 For decades, however, the relationship between fossil fuel combustion,

amounts to about 2,200,000,000,000 tons, equivalent to 600,000,000,000 tons of carbon. … The annual
consumption of coal, estimated by A. Krogh at 700,000,000 tons in 1902, adds yearly to the atmosphere about onethousandth of its present content in carbon dioxide. In a thousand years, then, if the rate were constant and no
disturbing factors interfered, the amount of CO, in the atmosphere would be doubled. If we take into account the
combustion of fuels other than coal and the large additions to the atmosphere from the sources previously
mentioned, the result becomes still more startling. Were there no counterbalancing of this increase in atmospheric
carbon, animal life would soon become impossible upon our planet.”); Robert E. Swain, “Atmospheric Pollution by
Industrial Wastes,” Ind. Eng. Chem., 15 (3), p. 296–301 (1923) (“The greatest single waste product in industry is a
gas, carbon dioxide, which is usually discharged as it is produced directly into the air….If all the coal consumed
annually in this country were completely burned, there would be produced approximately nine hundred thousand
billion cubic meters, or one billion eight hundred million metric tons of this gas. The combustion of petroleum
would add two hundred million metric tons, and of natural gas ninety million metric tons, while the burning or decay
of wood, and of plant products and tissues, would add an indeterminable but enormous total to these figures. … But
it is a remarkable fact that, rapidly disbursed as it is into the great ocean about us, this gas is present in the strikingly
small and uniform amount of three parts by volume of carbon dioxide to ten thousand parts of air, or three hundred
parts per million parts of air.”)
