Coastal Wetlands Highly Vulnerable to Sea-Level Rise

Photo: istockphoto.comSea-level rise from climate change is a serious global threat, and there is overwhelming scientific evidence that sea-level will continue to rise for centuries even if green house gas concentrations were to be stabilized today.

Recently, Brian Blankespoor, Benoit Laplante and I investigated potential impacts of sea-level rise on coastal wetlands. Our study indicates a rise in sea levels due to climate change of just one meter could destroy more than 60 percent of the developing world’s coastal wetlands currently found at one meter or less elevation. We estimate that such a rise would lead to economic losses of around $630 million per year.
