The dangers of data deficiency

The dangers of data deficiency

Below is a guest post by Chris Mull, a PhD student in the Dulvy Lab at Simon Fraser University.  Chris studies shark biology and evolutionary neuroecology.  You can read more about his research here. Over this past week science headlines have been flooded with the news that one-quarter of all chondrichthyans (sharks, skates, rays, and chimaeras) are […]


Ovik Banerjee 1989-2014

Ovik Banerjee 1989-2014

I regret sharing the devastating news that Ovik Banerjee passed away last Monday.  He was only 24. Ovik worked in our lab in 2011. He and Amanda and Juan de spent the summer that year in Muisne Ecuador, working on a mangrove restoration – blue carbon project (DelVecchia et al. 2013).  This is what Ovik […]

Scientists as advocates and is climate change really bo-ho-horing?

There has been a broad, intense, and interesting discussion about science outreach sparked by Gavin Schmidt’s talk at AGU this year (below). The Yale forum has a great piece on it, breaking down some of Gavin’s main points: Scientists must be careful, however, and follow a handful of rules of engagement that will protect their […]


Just a green crab, doin green crab thangs

I love science rap.  Especially rap by Eric Axelman:


Do the facts matter?

Do the facts matter?

Chris Mooney has an interesting piece on whether the climate change “consensus” is a useful policy approach. Is it changing the minds of people that formerly didn’t “believe in” climate change? And more broadly whether facts ever change minds. As two top researchers studying the science of science communication—a hot new field that combines public opinion research […]


Q: What does the new IPCC report say about sea level rise?

Q: What does the new IPCC report say about sea level rise?

A: Nothing good. See the plot below of observed past and predicted future sea level (rise). Note the two plotted future scenarios are based on the new Representative Concentration Pathways (RCPs): plausible trends in atmospheric CO2 (and other greenhouse gases) concentration named for the corresponding additional heat retained by 2100 in W m-2. For the past, proxy data are shown […]


Graph of the day: climate velocity of marine taxa

Graph of the day: climate velocity of marine taxa

From Pinsky et al. 2013 Science “Marine Taxa Track Local Climate Velocities”. Predicted and observed northward latitudinal shifts of marine taxa in the N Atlantic and N Pacific oceans. The velocity of climate (as first described by Burrows et al. 2012 PDF for the oceans) is an imperfect but fairly good predictor of geographic shift in […]

Parliament of Fools

new from Monbiot: The US disease has arrived in Britain: representatives waging an all-out war against science. By George Monbiot, published in the Guardian 17th September 2013 A “flat-earth love-in”. That’s how one MP described the debate he witnessed in parliament last week(1). The politics with which citizens of the US, Canada and Australia are […]

What we know about coral loss

What we know about coral loss

See updates below in red Without empirical evidence that a population or guild of critters is declining it is pretty hard to understand why they are becoming scarce or to justify any remediation. This kind of work is essentially ecological bookkeeping. Or a form of empirical environmental journalism. I hear all the time from science […]


My congressional testimony on Magnuson-Stevens

I will be testifying tomorrow before the Committee on Natural Resources on the Reauthorization of the Magnuson Stevens Fishery Conservation and Management Act. Watch the hearing live here. This is my opening statement: Chairman Hastings and Ranking Member DeFazio, My name is John Bruno and I am a marine community ecologist and Professor of Biology at […]


Top 10 crazy things said about climate change

10) “It could just be a shift on the axis.” —Congressman Bill Cassidy (R-LA) 9) “[Climate Change] led to the Vikings dominating Europe for several hundred years.” —Congressman Morgan Griffith (R-VA) 8) “Every cow in the world, you know, when they do what they do, you’ve got more carbon dioxide.” —Speaker of the House John […]

Global imprint of climate change on marine life

Global imprint of climate change on marine life

An NCEAS working group I was a minor participant in has an important new paper out in Nature Climate Change (Poloczanska et al 2013 PDF). Summary: We synthesized all available studies of the consistency of marine ecological observations with expectations under climate change. This yielded a metadatabase of 1,735 marine biological responses for which either regional or global climate […]


Saying goodbye to village life

Saying goodbye to village life

This evening we said a sad goodbye to our wonderful hosts in Nagigi village here in Fiji. Everyone has been incredibly welcoming and warm to us and it honestly felt like a great privilege to spend time in their company – more on that later. But for now, since it’s already late and we have another 4am […]

Meet the new Representative Concentration Pathways (RCPs)

Meet the new Representative Concentration Pathways (RCPs)

The Intergovernmental Panel on Climate Change (IPCC) has replaced their older climate change scenarios with ‘Representative Concentration Pathways’ (RCPs) developed for IPCC AR5 report, scheduled to be published in 2014. Unlike the scenarios they replace (A1, B1, A1F1, etc.), the RCPs are not based on social, technological, and economic storylines. Instead, they are simply plausible […]


Continued coral reef accretion requires vastly reduced CO2 emissions

Continued coral reef accretion requires vastly reduced CO2 emissions

An important new modeling study (Kennedy et al 2013  download PDF) forecasts the structural decay of Caribbean reefs based on emission scenarios from the new ‘representative concentration pathways’ (RCPs). Excerpted  Authors Summary: Coral reefs face multiple anthropogenic threats, from pollution and overfishing to the dual effects of greenhouse gas emissions: rising sea temperature and ocean […]


Fiji’s blue ocean – just to make you jealous

Fiji's blue ocean - just to make you jealous

Today was our first day of field work here in Fiji. We’re all exhausted from diving, interviewing, and processing fish samples. So I’m afraid all I have for you is some envy-inducing photos. (I promise to post more about the science soon!).
