Professor Laurence Smith reflects on the impact of drought and climate change on “economic powerhouse rivers” and offers ideas to reimagine their use, such as diverting rivers to deposit sediment on fragile coastline or removing structures to restore rivers to a free-flowing state. “Radical new thinking is the only way to make sure our rivers endure,” he said. “There are no new rivers left to tap.”

Brown study Breathe Providence monitors local air quality

To better understand the local distribution of air quality, University researchers (including professor Meredith Hastings) are setting up air pollution monitors across Providence in a study called Breathe Providence. Funded by the Clean Air Fund, the study aims to provide communities — especially those of lower socioeconomic status — with data to inform pollution reduction initiatives.

"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.

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.
