Global Warming: It’s All About Energy

by Michael T. Klare

Finally, after years of effort by dedicated scientists and activists like Al Gore, the issue of global warming has begun to receive the international attention it desperately needs. The publication on February 2 of the most recent report by the Intergovernmental Panel on Climate Change (IPCC), providing the most persuasive evidence to date of human responsibility for rising world temperatures, generated banner headlines around the world. But while there is a growing consensus on humanity’s responsibility for global warming, policymakers have yet to come to terms with its principal cause: our unrelenting consumption of fossil fuels.
When talk of global warming is introduced into the public discourse, as in Gore’s “An Inconvenient Truth,” it is generally characterized as an environmental problem, akin to water pollution, air pollution, pesticide abuse, and so on. This implies that it can be addressed – like those other problems – through a concerted effort to “clean up” our resource-utilization behavior, by substituting “green” products for ordinary ones, by restricting the release of toxic substances, and so on.

But global warming is not an “environmental” problem in the same sense as these others – it is an energy problem, first and foremost. Almost 90% of the world’s energy is supplied through the combustion of fossil fuels, and every time we burn these fuels to make energy we release carbon dioxide into the atmosphere; carbon dioxide, in turn, is the principal component of the “greenhouse gases” (GHGs) that are responsible for warming the planet. Energy use and climate change are two sides of the same coin.

Many political and business leaders wish to deny this fundamental reality. They may claim to accept the conclusions of the IPCC report. They will admit that vigorous action is needed to stem the buildup of greenhouse gases. But they will nevertheless seek to shield energy policy from fundamental change.

Typical of this approach is a talk given by Rex W. Tillerson, the CEO of Exxon Mobil, at a conference organized by Cambridge Energy Research Associates on February 13. As head of the world’s largest publicly traded energy firm, Tillerson receives special attention when he talks. That his predecessor Lee Raymond often disparaged the science of global warming lent his comments particular significance. Yes, Tillerson admitted, atmospheric carbon dioxide levels were increasing, and this contributed to the planet’s gradual warming. But then, in language characteristic of the industry, he added, “The scale advantages of oil and natural gas across a broad array applications provide economic value unmatched by any alternative.” It would therefore be a terrible mistake, he added, to rush into the development of energy alternatives when the consequences of global warming are still not fully understood.

The logic of this mode of thinking is inescapable. The continued production of fossil fuels to sustain our existing economic system is too important to allow the health of the planet to stand in its way. Buy into this mode of thought, and you can say goodbye to any hope of slowing – let alone reversing – the buildup of greenhouse gases in the atmosphere.
