TITLE: Sea level as an indicator of climate change
Reconstructions of global mean sea level (MSL) based on tide gauge observations include decadal time scale MSL fluctuations that have been attributed to various climate phenomena, including volcanic activity, enhanced land ice melt, and changes in ocean circulation and heat uptake. Alternatively, these decadal MSL variations may be artifacts associated with the limited spatial sampling afforded by the tide gauge network. To gain further insight into the sea level response to climate forcing, we consider how effective the temporally evolving tide gauge network is at distinguishing regional sea level patterns from MSL change. The results suggest marked differences in global and regional sea level variations over the past century compared to the satellite altimeter period. Connections between regional sea level change and variability in surface wind patterns will be considered.
