When Climate Change Was a Nonpartisan Issue
June 23, 1988, marked the date on which climate change became a national issue. In聽聽before the U.S. Senate Energy and Natural Resources Committee, James Hansen, then director of NASA鈥檚 Institute for Space Studies, stated that 鈥済lobal warming has reached a level such that we can ascribe with a high degree of confidence a cause-and-effect relationship between the greenhouse effect and observed warming 鈥 In my opinion, the greenhouse effect has been detected, and it is changing our climate now.鈥
Hansen鈥檚 testimony made clear the threats posed by climate change and attributed the phenomenon to human exploitation of carbon energy sources. Its impact was dramatic, capturing and other major newspapers. As politicians, corporations, and environmental organizations acknowledged and began to address this issue, climate change entered into the political arena in a largely nonpartisan fashion.
Yet despite decades of public education on climate change and international negotiations to address it, progress continues to stall. Why?
One reason for the political inaction is the gaping divide in public opinion that resulted from a deliberate鈥攁nd still controversial鈥攎isinformation campaign to redirect the public discussion on climate change in the years following Hansen鈥檚 testimony.
Just as predicted
Four years after Hansen testified to Congress, 165 nations signed an international treaty, the United Nations Framework Convention on Climate Change. They committed themselves to reducing carbon emissions to avoid dangerous disruption of the Earth鈥檚 climate system, defined as limiting future temperature increases to 2 degrees Celsius. The signatories have now held 25 annual UNFCCC conferences dedicated to developing goals, timetables, and methods for mitigating climate change, the most consequential of which are encompassed in the Paris Agreement of 2015.
But as of today, not one single major northern industrial country has fulfilled its , and the nonprofit Climate Action Tracker has rated the United States鈥 plan to achieve the Paris goals
Last year, President Trump, advised by EPA Administrator Scott Pruitt, pulled the U.S. out of the international Paris agreement on climate change, marking the dramatic shift away from one-time Republican support for action on global warming.
Concern about climate change now falls along partisan lines.
There have been more than 600 congressional hearings on climate change, according to my calculations, and numerous attempts to pass binding limits on carbon emissions. Despite those efforts, the United States has yet to take meaningful action on the problem鈥攁 discrepancy compounded by President Donald Trump鈥檚 decision last year to .
In the three decades since Hansen鈥檚 testimony, the scientific certainty about the human causes and catastrophic effects of climate change on the biosphere and social systems has only grown stronger. This has been documented in five Intergovernmental Panel on Climate Change assessment reports, three U.S. National Climate Assessments, and thousands of peer-reviewed papers.
Yet carbon dioxide levels continue to rise. In 1988, atmospheric CO2 levels stood at 353 parts per million, or ppm, the way to measure the concentration of CO2 molecules in the atmosphere. As of June, they have ,聽the highest monthly average .
The of these increased concentrations are just as Hansen and others predicted, from disastrous wildfires in the western U.S. and massive hurricanes associated with historical flooding to extended droughts, rising sea levels, increasing ocean acidification, the pervasive spread of tropical diseases, and the bleaching and death of coral reefs.
Massive gap on public opinion
Future generations will look back on our tepid response to global climate disruption and wonder why the world did not act sooner and more aggressively.
One answer can be found in the polarization of public opinion over climate change in the United States. The shows that concern about climate change now fall along partisan lines, with 91 percent of Democrats saying they are worried a great deal or fair amount about climate change, while only 33 percent of Republicans saying the same.
Clearly, a massive gap between Republicans and Democrats has emerged regarding the nature and seriousness of climate change. This has led to an extreme political conflict over the need for climate action and helps to explain Congress鈥檚 failure to pass meaningful legislation to reduce carbon emissions.
Polarizing public opinion
The current political stalemate is no accident. Rather, it is the result of a well-financed and sustained campaign by vested interests to develop and promulgate misinformation about climate science.
documents the coordinated efforts of conservative foundations and fossil fuel corporations to promote uncertainty about the existence and causes of climate change and thus reduce public concern over the issue. Amplified by , this campaign has significantly altered the nature of the public debate.
These findings are supported by recent showing that since the 1970s top executives in the fossil fuel industry have been well aware of the evidence that their products amplify climate warming emissions. Indeed, industry scientists had conducted their own extensive research on the topic and participated in contemporaneous scientific discussions.
The corporate drive to spread climate misinformation continued beyond fighting Kyoto.
The American Petroleum Institute, an industry trade group, even circulated these research results to its members. By 1978, a senior executive at ExxonMobil had creating a worldwide 鈥淐O2 in the Atmosphere鈥 research and development program to determine an appropriate response to growing evidence of climate change.
Unfortunately, that path wasn鈥檛 taken. Instead, in 1989, a group of fossil fuel corporations, utilities, and automobile manufacturers banded together to form the Global Climate Coalition. The group was convened to prevent the U.S. adoption of the , an international agreement to limit greenhouse gas emissions. In its public statements, the coalition鈥檚 was to claim global warming was real but that it could be part of a natural warming trend.
The corporate drive to spread climate misinformation continued beyond fighting Kyoto. In 1998, API, Exxon, Chevron, Southern Co. and various conservative think tanks initiated a broad public relations campaign with a goal of ensuring that the 鈥溌燽ecomes part of the 鈥榗onventional wisdom.鈥欌
While that coalition disbanded in 2001, ExxonMobil reportedly continued quietly to fund climate misinformation, funneling donations through conservative 鈥渟keptic鈥 think tanks such as the Heartland Institute, until 2006, when the nonprofit Union of Concerned Scientists . ExxonMobil鈥攖he nation鈥檚 largest and wealthiest company鈥攃ontinues to work with the , a self-described public-private partnership of corporations and conservative legislators, to .
Holding fossil fuel companies responsible
ExxonMobil鈥檚 conduct鈥攑romoting uncertainty about climate science it knew to be accurate鈥攈as generated public outrage and led New York鈥檚 attorney general to into whether the company has illegally misled the public and its investors about the risks of climate change. This trend in litigation has expanded, and there are now several ongoing climate litigation suits.
While important, lawsuits cannot fully address the larger issues of corporate social and political responsibility to acknowledge and address climate change. Just as Congress investigated in the 1990s efforts by the tobacco industry to dupe the public into believing its products were harmless, a full and open inquiry is needed now to unmask the vested interests behind scientific misinformation campaigns that continue to delay our efforts to mitigate a global threat.
American voters deserve to know who is behind climate disinformation efforts.
At a minimum, the U.S. needs to change the system of hidden funding, in which companies such as ExxonMobil or the Koch brothers use pass-through organizations to . Current U.S. tax rules for nonprofit organizations, including climate-denying think tanks, do not require them to reveal their donors, enabling them to support large-scale political activities while remaining unaccountable. American voters deserve to know who is behind climate disinformation efforts, and revising nonprofit reporting laws is a good place to begin.
In my view, the central concern here is nothing less than the moral integrity of the public sphere. The Declaration of Independence states that governments 鈥渄erive their just powers from the consent of the governed.鈥 But when vested interests with outsize economic and cultural power distort the public debate by introducing falsehoods, the integrity of Americans鈥 deliberations is compromised.
So it is with the fossil fuel industry鈥檚 efforts to distort public discourse on the urgent subject of climate change. If corporations and public relations firms can systematically alter the national debate in favor of their own interests and against those of society as a whole, then democracy itself is undermined. I believe Congress can and should act to investigate this issue fully. Only then can we restore trust and legitimacy to American governance and fulfill our society鈥檚 moral duty to address climate change at a scale commensurate with its significance.
