DEEPS Assistant Professor Daniel Ibarra shared his thoughts with the Brown Daily Herald in their recent story about Brown's Southeast Asian Studies Initiative: "It’s a way for the students to push the faculty and the upper administration to think: How can we not just be a local university, but how can we expand our global impact?”

DEEPS alumnus David Grinspoon ’82, senior scientist at the Planetary Science Institute in Tucson, Arizona, has been selected by NASA to participate in its independent study team on unidentified aerial phenomena, aka UFOs.

"We're going to see almost a foot – somewhere between nine and 11 inches – of sea level rise by 2050 – a generation and a half, we see that amount," Fox-Kemper explained while standing at the waters’ edge. "And the 2050 numbers are already baked in. So even if we were to cut all of our emissions today, we still are going to see sea level rise."

Why was the long-term global cooling trend of the Cenozoic interrupted by a several-million-year interval of warming during the middle of the Miocene? Herbert et al. present a reconstruction of global ocean crustal production to show that tectonic degassing of carbon can account for most of the long-term ice sheet and global temperature evolution for the past 20 million years (see the Perspective by von der Heydt). These results provide further support for the idea that sea floor spreading rates can control global changes in climate.

Muskrats have been considered so prevalent and unremarkable that even people in tune with environmental goings-on have been unaware of the species’ 50-year decline. Biologists noted the nationwide trend early through trappers’ harvest data, but earnest study is a recent phenomenon.

Sharp fronts and eddies that are ubiquitous in the world ocean, as well as features such as shelf seas and under-ice-shelf cavities, are not captured in climate projections. Such small-scale processes can play a key role in how the large-scale ocean and cryosphere evolve under climate change, posing a challenge to climate models.
