Worldwide coastal warming assessment data

Coastal warming from 1982 to 2011 (in °C/decade)

This file (in google earth format, .kmz) shows the average changes in sea surface temperature (SST) observed along the coastlines of the world since 1982. Please click on the coastal points to get more information.

Please provide acknowledgement of the use of these data in publications or presentations. See the folowing examples:

  • Acknowledgments example:”Coastal SST warming data were obtained from the Worldwide Coastal Warming Assessment project website at (2011).”
