SMOKE AND FUMES
“[M]an has a time window of five to
ten years before the need for hard
decisions regarding changes in
energy strategies might become
critical.”
— JAMES BLACK, 1978
1978-1979. The report acknowledges
“[t]here is no doubt that increases in
fossil fuel usage and decreases in forest
cover are aggravating the potential
problem of increased CO2 in the
atmosphere.”117 Significantly, the memo
expressed the view that Exxon possessed
the technology to dramatically reduce
emissions, but that doing so would result
in an unacceptable increase in costs.
By 1981, Exxon had internally
acknowledged the risks of climate change
and the role fossil fuel combustion played
in increasing carbon dioxide
concentrations in the atmosphere. A
position memo from Henry Shaw in May
1981 includes as Exxon’s current position
on the CO2 greenhouse effect that a three
degree increase in average temperatures
will result in a ten degree increase at the
poles, “[m]ajor shifts in rainfall/
agriculture,” and that “[p]olar ice may
melt.”118
By 1982, any lingering doubts were put
to rest by a memo from Roger Cohen,
then Director of Exxon’s Theoretical and
Mathematical Sciences Laboratory. In this
memo, Cohen noted that “a clear
scientific consensus had emerged
regarding the expected climatic effects of
increased atmospheric CO2.”119 This
consensus determined that doubling
“[In] summary, the results of our
research are in accord with the
scientific consensus on the effect of
increased atmospheric CO2 on
climate.”
— ROGER COHEN, 1982
atmospheric CO2 would result in a global
temperature increase of three degrees
Celsius, plus or minus 1.5 degrees
Celsius.120 In this memo, Cohen also
acknowledged the work of a scientist who
believed increased water evaporation and
cloud cover would suppress global
temperature increases. Cohen concluded,
however, that this analysis was consistent
with predictions that atmospheric
temperature increases would be nonuniformly distributed across the globe,
with little warming at the equator and
greatest warming at the poles. He
concludes that, “[in] summary, the results
of our research are in accord with the
scientific consensus on the effect of
increased atmospheric CO2 on
climate.”121
Later that year, on November 12, 1982,
Exxon circulated a 43-page climate
change primer to several members of
Exxon management to “familiarize Exxon
personnel with the subject.”122 By this
point, Exxon was fully aware and
internally acknowledging that climate
change was real, caused by burning fossil
fuels, and would have significant impacts
on the environment and human health
and wellbeing.
As Early as the 1970s and No
Later than the 1980s, Climate
Change Projections Were Being
Used in Business and Operational Planning
Internal documents uncovered by the Los
Angeles Times and the Columbia School
of Journalism demonstrate that by the
mid-1980s, Exxon was incorporating
climate change projections into its Arctic
operations planning while discounting
the risks when communicating with the
public.123
In 1986, a team of researchers led by Ken
Croasdale of Imperial oil, an Exxon
subsidiary, was “trying to determine how
global warming could affect Exxon’s
Arctic operations and its bottom line.” In
1991, Croasdale reported to an
engineering conference that “[c]ertainly
any major development with a life span
of say 30-40 years will need to assess the
impacts of potential global warming,”
and that “[t]his is particularly true of
15
Arctic and offshore projects in Canada,
where warming will clearly affect sea ice,
icebergs, permafrost, and sea levels.”124
Similarly, evidence uncovered by The
Guardian demonstrates that Shell was
also directly put on notice of climate risks
and incorporating those risks into
planning. A 1986 report seen by The
“Certainly any major development
with a life span of say 30-40 years
will need to assess the impacts of
potential global warming…This is
particularly true of Arctic and
offshore projects in Canada, where
warming will clearly affect sea ice,
icebergs, permafrost, and sea
levels.”
— KEN CROASDALE, 1986
Guardian addressed the issue directly. The
report “notes the large uncertainties in
climate science at the time but
nonetheless states: ‘the changes may be
the greatest in recorded history.’”125
Later, in 1989, Shell Oil announced that
it was redesigning a $3 billion natural gas
platform it had been designing for use in
the North Sea.126 The original design had
the platform sitting 30 meters above the
ocean’s surface, but the redesign would
raise the platform by one to two meters to
account for rising sea levels as a result of
global warming.127
This evidence of early action to protect
industry assets from climate change
should be considered a baseline for
further investigation into both prior and
subsequent industry conduct. Anecdotal
evidence, including interviews with longtime industry insiders, strongly suggests
the oil and gas industry may have begun
accounting for climate change in the
design of its own infrastructure far earlier
than the 1980s. In a filmed interview
with one of the authors of the present
report, a long-time oil industry engineer
reported that he had been instructed to
plan for melting permafrost in the design
and construction pads for the TransAlaska
Pipeline in the early 1970s.128 A second
