How serious of an issue is climate change? Does global warming really threaten human civilization? Can it be reversed, or is it already late?
In this exclusive interview for Truthout, two scholars, Noam Chomsky, one of the world’s leading public intellectuals, and Graciela Chichilnisky, a renowned economist and climate change authority who wrote and designed the carbon market of the Kyoto Protocol, concur on a few key points. First of all, global warming and climate change constitute the greatest challenge facing humanity, and may pose an even greater threat to our species than that of nuclear weapons. Secondly, the operations of the capitalist world economy are at the core of the climate change threat because of over-reliance on fossil fuels and a perverse sense of economic values. Thirdly, the world needs to adopt alternative energy systems as quickly as possible. And finally, it is crucial to explore technologies to assist us in reversing climate change — as time is running out.
C. J. Polychroniou: A consensus seems to be emerging among scientists and even political and social analysts that global warming and climate change represent the greatest threat to the planet. Do you concur with this view, and why?
Noam Chomsky: I agree with the conclusion of the experts who set the Doomsday Clock for the Bulletin of Atomic Scientists. They have moved the Clock two minutes closer to midnight — three minutes to midnight — because of the increasing threats of nuclear war and global warming. That seems to me a credible judgment. Review of the record shows that it’s a near miracle that we have survived the nuclear age. There have been repeated cases when nuclear war came ominously close, often a result of malfunctioning of early-warning systems and other accidents, sometimes [as a result of] highly adventurist acts of political leaders. It has been known for some time that a major nuclear war might lead to nuclear winter that would destroy the attacker as well as the target. And threats are now mounting, particularly at the Russian border, confirming the prediction of George Kennan and other prominent figures that NATO expansion, particularly the way it was undertaken, would prove to be a “tragic mistake,” a “policy error of historic proportions.”
As for climate change, it’s by now widely accepted by the scientific community that we have entered a new geological era, the Anthropocene, in which the Earth’s climate is being radically modified by human action, creating a very different planet, one that may not be able to sustain organized human life in anything like a form we would want to tolerate. There is good reason to believe that we have already entered the Sixth Extinction, a period of destruction of species on a massive scale, comparable to the Fifth Extinction 65 million years ago, when three-quarters of the species on earth were destroyed, apparently by a huge asteroid. Atmospheric CO2 is rising at a rate unprecedented in the geological record since 55 million years ago. There is concern — to quote a statement by 150 distinguished scientists — that “global warming, amplified by feedbacks from polar ice melt, methane release from permafrost, and extensive fires, may become irreversible,” with catastrophic consequences for life on Earth, humans included — and not in the distant future. Sea level rise and destruction of water resources as glaciers melt alone may have horrendous human consequences.
Graciela Chichilnisky: The consensus is that climate change ranks along with nuclear warfare as the top two risks facing human civilization. If nuclear warfare is believed to be somewhat controlled, then climate change is now the greatest threat.
As difficult as it is to eliminate the risk of nuclear warfare, it requires fewer changes to the global economy than does averting or reversing climate change. Climate change is due to the use of energy for industrial growth, which has been and is overwhelmingly based on fossil fuels. Changing an economic system that is bent on uncontrolled and poorly measured economic growth and depends on fossil energy for its main objectives, is much more difficult than changing how nuclear energy is used for military purposes. Some think it may be impossible.
Virtually all scientific studies point to increased temperatures since 1975, and a recent story in The New York Times confirms that decades-long warnings by scientists on global warming are no longer theoretical as land ice melts and sea levels rise. Yet, there are still people out there who not only question the widely accepted scientific view that current climate change is mostly caused by human activities, but also cast a doubt on the reliability of surface temperatures. Do you think this is all politically driven, or also caused by ignorance and perhaps even fear of change?
Chomsky: It is an astonishing fact about the current era that in the most powerful country in world history, with a high level of education and privilege, one of the two political parties virtually denies the well-established facts about anthropogenic climate change. In the primary debates for the 2016 election, every single Republican candidate was a climate change denier, with one exception, John Kasich — the “rational moderate” — who said it may be happening but we shouldn’t do anything about it. For a long time, the media have downplayed the issue. The euphoric reports on US fossil fuel production, energy independence, and so on, rarely even mention the fact that these triumphs accelerate the race to disaster. There are other factors too, but under these circumstances, it hardly seems surprising that a considerable part of the population either joins the deniers or regards the problem as not very significant.
