Keeping an eye on how scientific information embargoes affect news coverage

Another embargo break for PNAS, for a climate change paper

with one comment

pnas 14PNAS has had a rash of embargo breaks recently.

The journal’s press office sent this email to its media list a few minutes before 11 a.m. Eastern yesterday, about four hours before the journal’s scheduled embargo time:

Due to an embargo break, PNAS is lifting the embargo early on the following paper. All other articles are under the scheduled embargo:

  • Urban adaptation and regional climate warming

Urban adaptation strategies such as green roof, cool roof, and hybrid technologies can help offset not only future climate warming due to urban expansion but also temperature increases driven by greenhouse gases, according to a study. Recent modeling studies have suggested that in the absence of adaptive urban design the spread of population centers in the United States during the coming century could raise temperatures by as many as 3 degrees—independently of greenhouse gas-induced warming. Using a suite of regional climate simulations, Matei Georgescu and colleagues assessed the ability of commonly proposed urban adaptation strategies, such as green roofs, cool roofs, and hybrid approaches to ameliorate the warming due solely to so-called megapolitan expansion. According to the authors, the simulations revealed that judicious planning and design choices can not only counteract rising temperatures due to increasing urban sprawl but also offset a significant portion of anticipated greenhouse gas-driven warming, at scales that extend beyond individual cities to large swaths of the country. According to the authors, urban-induced climate change depends on specific geographic factors that must be assessed when choosing optimal approaches, as opposed to universal solutions.

PNAS tells us:

We found stories in an Italian outlet called Gaia News and the web site Science Codex that were published ahead of the scheduled embargo. The author’s institution had posted a press release with incorrect embargo information.

This is the third time this year that PNAS has had to lift the embargo on papers early because of breaks.

  1. Would not call this an embargo break. It represents an error on the part of the author’s institution.
