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 »

What Works in Conservation 2018

23 05 2018

Do you have a copy of this book? If not, why not?


This book is free to download. This book contains the evidence for the effectiveness of over 1200 things you might do for conservation. If you don’t have a copy, go and download yourself a free one here, right now, before you even finish reading this article. Seriously. Go. You’ll laugh, you’ll cry, it’ll change your life.

Why you’ll laugh

OK, I may have exaggerated the laughing part. ‘What Works in Conservation 2018’ is a serious and weighty tome, 660 pages of the evidence for 1277 conservation interventions (anything you might do to conserve a species or habitat), assessed by experts and graded into colour-coded categories of effectiveness. This is pretty nerdy stuff, and probably not something you’ll lay down with on the beach or dip into as you enjoy a large glass of scotch (although I don’t know your life, maybe it is).

But that’s not really what it’s meant for. This is intended as a reference book for conservation managers and policymakers, a way to scan through your possible solutions and get a feel for those that are most likely to be effective. Once you have a few ideas in mind, you can follow the links to see the full evidence base for each study at, where over 5000 studies have been summarised into digestible paragraphs.

The book takes the form of discrete chapters on taxa, habitats or topics (such as ‘control of freshwater invasives’). Each chapter is split into IUCN threat categories such as ‘Agriculture’ or ‘Energy production and mining’. For each threat there are a series of interventions that could be used to tackle it, and for each of these interventions the evidence has been collated. Experts have then graded the body of the evidence over three rounds of Delphi scoring, looking at the effectiveness, certainty in the evidence (i.e., the quality and quantity of evidence available), and any harms to the target taxa. These scores combine to place each intervention in a category from ‘Beneficial’ to ‘Likely to be ineffective or harmful’. Read the rest of this entry »

Science + music = productivity

17 05 2018

da2a4c4015f37dcd15015a2bfcef2a2dA take on a small section of my recent book, The Effective Scientist, about the importance of music in science.

I don’t know any scientists who don’t love music, and I will go out on a limb by stating that most of us probably combine our science activities with music during the quieter times in front of the computer.

One tool that can effectively mask distractions when writing or coding, especially noisy ones, is music. I consider my earphones to be an essential tool of the science trade, for they allow me to ‘tune out’ as I ‘tune in’ to my favourite mood music.

However, a little caution is required here. If the music is set to loud to mask the ambient noises that you are presently finding annoying, you might discover that your capacity to concentrate is reduced. The style of music is also important. When I am writing actual text, anything that could induce the slightest foot tapping or head banging tends to send me off into space; I prefer something light and instrumental in these circumstances, like Vivaldi, Mozart, or Miles Davis.

On the contrary, if I am merely transcribing data, coding, analysing, or creating display items, then I tend to go more for heavy metal or electronica to set an intense pace. While this is absolutely a personal choice, you might do well inevitably to find some combination of music styles that works best for you.

I’m going to use this occasion though to list my top-10 metal/hard-core tracks that I find particularly good for coding. Somehow for me, heavy metal and coding go together like Vegemite and toast (but the combination doesn’t work for writing papers, although at this very moment I’m listen to some of the tracks listed below). This list is also a little window into my own frustration with the Anthropocene and the political inertia about limiting the damage we humans are doing to our own life-support system.

In no particular order, here are my top-10 heavy-metal/coding/angst/frustration tunes (listen to the lyrics — they help): Read the rest of this entry »

A life of fragmentation

9 05 2018

LauranceWhat do you say to a man whose list of conservation awards reads like a Star Wars film intro, who has introduced terms like the ‘hyperdynamism hypothesis’ to the field of ecology, and whose organisation reaches over one million people each week with updates of the scientific kind?

Interview with Bill Laurance by Joel Howland (originally published in Conjour)

Well, I started by asking what it is that leads him to love the natural world to the extent he does. His answer was disarmingly simple.

“I grew up in the country, on an Oregon cattle ranch, and I think my love of nature just evolved naturally from that. When I was a young kid my dad and I did some fishing and ‘rock-hounding’— searching for rare stones and fossils. As an adolescent and teen I loved heading off into a forest or wilderness, rifle in hand – back in those days you could do that – to see whatever I could find. I watched red foxes hunting, eagles mating, and even heard a mountain lion scream. I got to be a pretty good duck and game-bird hunter.”

He’s quick to point out, however, he realised his taste for guns was not so developed as his love of nature.

“I gave up my rifles for a camera, and enjoyed that even more. I really got into photography for a while. Nature has always just calmed and fascinated me —I guess that’s partly why I became a conservationist.”

Who is Bill Laurance?

William F. Laurance is one of the leading ecology and conservation scientists globally, publishing dozens of papers in journals like Nature and Science, and rewriting the way scientists in the field research the complex interactions between flora and fauna — particularly in rainforests like the Amazon.

He is a Distinguished Research Professor at James Cook University in Australia, a Fellow of the Australian Academy of Science and the American Association for the Advancement of Science, and has received an Australian Laureate Fellowship from the Australian Research Council.

All this for a man from western USA who dreamed of running a zoo. Instead, he has travelled a path of intricate and game-changing research, trailblazing awareness campaigns and inspirational writings that have driven the way many see the environment over the past few decades.

Despite this profile, Laurance gave some time to tell Conjour about his life, his passion and his aims. I asked him what — considering his impressive CV — the future holds.

His response seems a real insight to the man. Read the rest of this entry »

Why do they take so long?

4 05 2018

phd1This is probably more of an act of self-therapy on a Friday afternoon to alleviate some frustration, but it is an important issue all the same.

An Open Letter to academic publishers:

Why, oh why, do some of you take so bloody long to publish our papers online after acceptance?

I have been known to complain about how the general academic-publishing industry makes sickening amount of profit on the backs of our essentially free labour, and I suppose this is just another whinge along those lines. Should it take weeks to months to publish our papers online once they are accepted?

No. it shouldn’t.

I’m fully aware that most publishing companies these days outsource the actual publishing side of things to subcontracting agencies (and I’ve noticed more and more that these tend to be in developing nations, probably because the labour is cheaper), and that it can take someone some time to work through the backlog of Word or Latex documents and produce nice, polished PDFs.

Prioritising your academic tasks

18 04 2018

The following is an abridged version of one of the chapters in my recent book, The Effective Scientist, regarding how to prioritise your tasks in academia. For a more complete treatise of the issue, access the full book here.

How the hell do you balance all the requirements of an academic life in science? From actually doing the science, analysing the data, writing papers, reviewing, writing grants, to mentoring students — not to mention trying to have a modicum of a life outside of the lab — you can quickly end up feeling a little daunted. While there is no empirical formula that make you run your academic life efficiently all the time, I can offer a few suggestions that might make your life just a little less chaotic.

Priority 1: Revise articles submitted to high-ranked journals

Barring a family emergency, my top priority is always revising an article that has been sent back to me from a high-ranking journal for revisions. Spend the necessary time to complete the necessary revisions.

Priority 2: Revise articles submitted to lower-ranked journals

I could have lumped this priority with the previous, but I think it is necessary to distinguish the two should you find yourself in the fortunate position of having to do more than one revision at a time.

Priority 3: Experimentation and field work

Most of us need data before we can write papers, so this is high on my personal priority list. If field work is required, then obviously this will be your dominant preoccupation for sometimes extended periods. Many experiments can also be highly time-consuming, while others can be done in stages or run in the background while you complete other tasks.

Priority 4: Databasing

This one could be easily forgotten, but it is a task that can take up a disproportionate amount of your time if do not deliberately fit it into your schedule. Well-organised, abundantly meta-tagged, intuitive, and backed-up databases are essential for effective scientific analysis; good data are useless if you cannot find them or understand to what they refer.

My interview with Conservation Careers

10 04 2018


The online job-search engine and careers magazine for conservation professionals — Conservation Careers — recently published an interview with me written by Mark Thomas. Mark said that he didn’t mind if I republished the article here.

As we walk through life we sometimes don’t know where our current path will take us. Will it be meaningful, and what steps could we take? Seeking out and talking to people who have walked far ahead of us in a line of work that we are interested in could help shape the next steps we take, and help us not make the same mistakes that could have cost us precious time.

A phrase that I love is “standing on the shoulders of giants” and this conversation has really inspired me — I hope it will do for you as well.

Corey Bradshaw is the Matthew Flinders Fellow in Global Ecology at Flinders University, and author to over 260 hundred peer-reviewed articles. His research is mainly in the area of global-change ecology, and his blog ConservationBytes critiques the science of conservation and has over 11,000 followers. He has written books, and his most recent one ‘The Effective Scientist’ will be published in March (more on this later).

What got you interested in ecology and conservation?

As a child I grew up in British Columbia, Canada, my father was a fur trapper, and we hunted everything we ate (we ate a lot of black bear). My father had lots of dead things around the house and he prepared the skins for the fur market. It was a very consumptive and decidedly non-conservation upbringing.

Ironically, I learnt early in life that some of the biggest impediments to deforestation through logging was the trapping industry, because when you cut down trees nothing that is furry likes to live there. In their own consumptive ways, the hunters were vocal and acted to protect more species possibly than what some dedicated NGOs were able to.

So, at the time, I never fully appreciated it, but not having much exposure to all things urban and the great wide world, and by spending a lot of time out in the bush, I ended up appreciating the conservation of wild things even within that consumptive mind-set. Read the rest of this entry »
