Climate Change on Tropical Islands: Dynamics and Impacts
by Kristopher B. Karnauskas - Cooperative Institute for Research in Environmental Sciences & Department of Atmospheric and Oceanic Sciences, University of Colorado Boulder
Tropical islands are home to some of the most vulnerable human and natural systems on Earth. For example, coral reefs are susceptible to ocean warming, penguins (on the Galapagos) depend on a marine food web fueled by upwelling, and remote human civilizations are particularly sensitive to freshwater resources. Our ability to connect large-scale dynamics to such local impacts is fundamentally limited by model resolution and sparse observations. In this synthesis talk, I will present my latest research aimed at leveraging in situ measurements, satellite observations, and global climate model simulations toward mechanistic and quantitative projections of anthropogenically forced changes in tropical climate and their likely impacts on marine ecosystems and remote human populations.
