Sea Levels and Climate Change

author: David T. Pugh, Intergovernmental Oceanographic Commission - UNESCO

Description

Popular interest and scientific concerns have focussed on the potential for sea level rise and increased risks of coastal flooding in a future warmer world.

This talk will review the recent global evidence for changes, including the 2007 IPCC Report and look in detail at changes observed at the principal UK Tide Gauge site, Newlyn, from 1915 to 2005. Changes may include not only mean sea level rises, but also increased meterorological effects on surges, and changes in tidal regimes.
