Communicating climate change

5 06 2018

Both the uncertainty inherent in scientific data, and the honesty of those scientists who report such data to any given audience, can sow doubt about the science of climate change. The perception of this duality is engrained in how the human mind works. We illustrate this through a personal experience connecting with global environmentalism, and synthesise some guidelines to communicate the science of climate disruption by humans.

In January 2017, the Spanish environmental magazine Quercus invited us to give a talk, at the Cabinet of Natural History in Madrid, about our article on the effects of climate change on the feeding ecology of polar bears, which made to Quercuscover in February 2017 (1) — see blog post here. During questions and debate with the audience (comprising both scientists and non-scientists), we displayed a graph illustrating combinations of seven sources of energy (coal, water, gas, nuclear, biomass, sun and wind) necessary to meet human society’s global energy needs according to Barry Brook & Corey Bradshaw (2). That paper supports the idea that nuclear energy, and to a lesser extent wind energy, offer the best cost-benefit ratios for the conservation of biodiversity after accounting for factors intimately related to energy production, such as land use, waste and climate change.

While discussing this scientific result, one member of the audience made the blunt statement that it was normal that a couple of Australian researchers supported nuclear energy since Australia hosts the largest uranium reservoirs worldwide (~1/3 of the total). The collective membership of Quercus and the Cabinet of Natural History is not suspicious of lack of awareness of environmental problems, but a different matter is that individuals can of course evaluate a piece of information through his/her own and legitimate perspective.

The stigma of hypocrisy

Indeed, when we humans receive and assimilate a piece of information, our (often not self-conscious) approach can range from focusing on the data being presented to questioning potential hidden agendas by the informer. However, the latter can lead to a psychological trap that has been assessed recently (3) — see simple-language summary of that assessment in The New York Times. In one of five experiments, a total of 451 respondents were asked to rank their opinion about four consecutive vignettes tracking the conversation between two hypothetical individuals (Becky & Amanda) who had a common friend. During this conversation, Amanda states that their friend is pirating music from the Internet, and Becky (who also illegally downloads music) can hypothetically give three alternative answers: Read the rest of this entry »

Appalling behaviour of even the most influential journalists

I’ve said it a few times in public and in private – one of the main reasons I, as a busy scientist with probably insufficient time to devote to a lay blog (no different to any busy scientist, mind), got into this whole gig in the first place was to fight back against dodgy reporters and shonky ‘journalists’.

For the most part I have to say that I’ve been represented reasonably well in the media – even if most of it is owned by a few highly questionable moguls who espouse wildly partisan views. There have been a few occasions though where I’ve been the victim of simply crap reporting, terribly investigation and downright dirty tactics done by so-called journalists. I’ve talked about this on a few occasions on (see ‘Crap environmental reporting‘, ‘Science turned bad by the media‘ and ‘Poor media coverage promotes environmental apathy and untruths‘).

In a bit of a coincidental turn of events, Bill Laurance sent me an interesting piece published in Nature on this very subject just while Paul Ehrlich and I (most of you know that Paul is in Adelaide at the moment) were talking about ways in which scientists could turn around public opinion from one of suspicion of science, logic and intellectualism, to one applauding the application of objective techniques to solve the world’s worst problems. Paul half-jokingly said “what if there is no solution?” – but I suspect that one such as he has found that constant writing, outreach and excellent research are the only ways to tear down the walls of ignorance, despite all the stupidity of certain elected officials. Two steps forward, one step back.

Bill suggested ConservationBytes would be a good place to reproduce this excellent article by Simon Lewis of the University of Leeds, and I agree. So here it is: Read the rest of this entry »

Wolves in sheep’s clothing: industrial lobbyists and the destruction of tropical forests

25 10 2010



As of this morning, a group of distinguished scientists (which I have had the honour of being invited to join) has released an Open Letter to be published in various media outlets worldwide. The letter addresses some of our major concerns over the misinterpretation of facts, and openly misleading statements, by proponents of deforestation in the Asian tropical region. Professor Bill Laurance, an old favourite on, has led the charge and organised a most impressive and shocking list of assertions. I produce the letter below – I encourage all my readers to distribute it as far and wide as possible in the social media-verse.

An Open Letter about Scientific Credibility and the Conservation of Tropical Forests

To whom it may concern:

As professional scientists employed by leading academic and research institutions, we are writing to alert the general public about some of the claims and practices being used by the World Growth Institute (WGI) and International Trade Strategies Global (ITS), and their affiliated leadership.

WGI and ITS operate in close association. ITS is owned by Alan Oxley, an Australian industrial lobbyist, former trade representative, and former Ambassador who also heads WGI. According to its website1, ITS also has “close associations” with several politically conservative US think tanks, including the American Enterprise Institute, the Competitive Enterprise Institute, and the Heritage Foundation.

In our personal view, WGI and ITS — which are frequently involved in promoting industrial logging and oil palm and wood pulp plantations internationally — have at times treaded a thin line between reality and a significant distortion of facts. Specifically, we assert that: Read the rest of this entry »
