Greta Thunberg’s speech to the UN Climate Action Summit
My message is that we’ll be watching you. This is all wrong. I shouldn’t be up here. I should be back in school, on the other side of the ocean. Yet you all come to us young people for hope. How dare you? You have stolen my dreams, and my childhood, with your empty words.…

Bruno et al. 2019 ARMS review: Supplemental info on MPA enforcement
One question I’ve gotten recently after presenting the results of the primary meta-analysis in this paper is whether the MPAs (most of which are fully protected marine reserves) were effective in protecting fish populations. Are they well-designed, well-enforced, etc. and are there more fishes, particularly herbivorous fishes, inside them than in neighboring unprotected sites? It’s…

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?
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…

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…

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…
