Future changes in wind-wave patterns have broad implications for ecosystems, as well as the design and operation of coastal, near-and-off-shore industries. Changes in response to global warming may further exacerbate the anticipated vulnerabilities of coastal regions to projected sea-level rise.

This research investigated surface wind and wave response to global warming, using the GFDL coupled atmosphere-wave model (HiRAM, coupled to WAVEWATCH III). Sea surface temperatures were perturbed using projections for climate late in the 21st century, generated by coupled models for the IPCC – Assessment Report 4 (A1B scenario).

Change in the global wind-wave climate is one of the main drivers, in the assessment of the effects of climate change on coastal erosion and risks to coastal population and ecosystems, as recognized by the IPCC Working Group II (Nicholls, et al. 2007). The goal of this study was to provide global dynamic wave projections for the remainder of this century.
