Published in Nature Climate Change: Future Freshwater Stress for Island Populations

April 10, 2016

By accounting for [evaporation] at 80 island groups distributed among Earth’s major ocean basins, we reveal a robust yet spatially variable tendency towards increasing aridity at over 73% of island groups (16 million people) by mid-century ... has important implications for climate change adaptation scenarios for vulnerable human populations living on islands across the world ocean.Read more »

Published in Nature SREP: Mitigation of Coral Reef Warming Across the Central Pacific by the Equatorial Undercurrent: A Past and Future Divide

Feb. 16, 2016

A unique suite of in situ measurements coupled with GCM simulations enables us to quantify the mitigation potential of the projected circulation change for three coral reef ecosystems under two future scenarios ... The pace and extent to which GCM projections overwhelm historical trends will play a key role in defining the fate of marine ecosystems across the tropical Pacific.Read more »

Dec. 1, 2015

"Upon stepping off the HMS Beagle in 1835, what biota would Charles Darwin have found, and how might that have influenced contemporary thought, philosophy, religion, and the development of evolutionary biology? It is this fluke of geography that helped create such abundant biodiversity in the Galápagos, but also the islands vulnerability to Earth’s great climatic heartbeat, El Niño."Read more »
