Climate Change Denial: Heads in the Sand

Climate Change Denial: Heads in the SandJohn Cook’s website Skeptical Science is held in high regard for its patient examination of the arguments put up by climate change deniers and its marshalling of the answers mainstream climate science provides. The result is quietly devastating as the scientific inadequacy of the deniers’ arguments becomes apparent.

Cook has now collaborated with environmental scientist Haydn Washington in a book which puts denial in all its forms under the spotlight of reason and challenges readers to recognise it for the delusion it is. Climate Change Denial: Heads in the Sand not only focuses on the deniers who claim that the science is wrong but also, as the subtitle indicates, conducts a telling examination of the full range of societal denial. Some denial is active and aggressive, but the persistent refusal of society to adequately face up to the reality of climate change is also a form of denial, one which the book addresses with urgency.

Adapting to climate change in Vietnam and the Philippines

I stumbled across a documentary programme on BBC World during the weekend, Nature Inc. It visited two Asian regions where the impacts of climate change are being experienced and described the active local measures under way to cope with them. It’s the sort of programme we ought to be seeing a great deal more of as the evidence of climate change effects accumulate around the world. The narrator presumably felt obliged to mention in passing that sceptics dispute the impacts of climate change identified by the local people, but that kind of disputing will surely wither in the face of the realities such populations are facing. Facing with energy and purpose in the two cases covered by the short documentary.

Ratcliffe coal protesters invited to appeal conviction

The defence of the Ratcliffe coal power plant protesters in the UK, charged with conspiracy to commit aggravated trespass, was that they were acting through “necessity” to prevent death and serious injury caused by carbon dioxide emissions and climate change. James Hansen was among the defence witnesses, testifying to the reality of the danger from climate change. The prosecution argued that the defendants were not really intending to stop carbon emissions, but instead engaged in a publicity stunt. I wrote in this post in January of the lenient sentencing from a judge who was clearly impressed by the motivation of these “decent men and women with a genuine concern for others”. They were found guilty and had to be punished, albeit leniently.

Their conviction now appears likely to be overturned. The Director of Public Prosecutions, no less, has urged them to appeal their convictions after allegations that police suppressed potentially crucial evidence from an undercover police officer. “I have invited the defence to lodge an appeal and to include the issue of non-disclosure of material relating to the activities of an undercover police officer in any grounds of appeal.”

Alley’s documentary: upbeat and optimistic

Richard Alley’s book Earth: The Operators’ Manual, which I reviewed recently, was written as a companion to a PBS documentary of the same name. The documentary has recently screened in the US and is now available for viewing here. The broad themes are the same as those of the book. They’re not complicated: taking our energy from fossil fuels has caused climate change, but there are clean energy alternatives more than adequate to human needs and the sooner we move to deploy them the better.

Funded by the National Science Foundation, the documentary takes Alley to many places and countries, including New Zealand. He dwells on the human need for energy, the kind of energy demands a growing population will make, and the ultimate inability of fossil fuels, a limited resource, to meet that demand even if we could carry on burning them with impunity. But we can’t, and Alley explains why. A visit to the Franz Josef and Tasman glaciers, with some great photography, is part of what he uses to explain the real world impact of changing levels of CO2. A fascinating visit to the national ice core laboratory in Denver, Colorado demonstrates that today atmospheric CO2 is at a level not seen in cores that go back as far as 400,000 years – far above them, in fact. Then it’s back to New Zealand as, against the background of Rotorua thermal activity, Alley explains the isotopic evidence that backs up the relative volume measurements to confirm that the increased CO2 is the result of burning fossil fuels, dwarfing natural volcanic processes.

Engaging the Public with Climate Change

Engaging the Public with Climate Change: Behaviour Change and CommunicationClimate scientists and those working in associated fields have established a clear picture of human-caused climate change and what it is likely to mean in the future. The basic information is readily understandable. It’s alarming in what it portends and a rational human society would by now be well on its way to the change of direction which would reduce the need for alarm. But we are not well on the way and there’s little urgency in our approach to the issue. Wide public alarm is rarely even voiced, let alone a stimulus to determined action. The science may be clear, but its appropriation by society at large is obviously no straightforward matter.

Can the social sciences help us? I was attracted by the title of a recently published book, Engaging the Public with Climate Change: Behaviour Change and Communication, edited by three academics, Lorraine Whitmarsh, Saffron O’Neill and Irene Lorenzoni. In its twelve chapters a couple of dozen social researchers and practitioners look at how climate change can be constructively woven into public perception and action. The writers are clear about the urgent need to tackle climate change, but the book doesn’t offer strong advocacy so much as close investigation of the dynamics at work in obtaining and supporting positive public engagement.
