Assessment of Climate Impacts on Oceans and Marine Resources of the United States

Session ID#: 28475

Session Description:
The 4th US National Climate Assessment (NCA4) has been asked to evaluate the risks to the United States from a changing climate and to consider vulnerabilities and opportunities to adapt. This tutorial will provide an overview of the assessment process and will present draft key findings related to oceans and marine resources. One of the emerging themes from the entire assessment is the heightened vulnerability of coastal communities to climate change. Many coastal communities, including island communities in the continental US and US territories, are highly dependent on marine ecosystems that are changing rapidly.  These communities also face rising sea level, and the challenges are compounded for communities that are isolated geographically or culturally. Recent marine heatwaves, including the 2012 North Atlantic heatwave and the 2014/15 “Blob” in the North Pacific also reveal the complex connections between people and changing ocean conditions.  Abrupt warming resulted in changes in the seasonality and productivity of key fisheries, expanded harmful algal blooms, and revealed unexpected interactions between fisheries and protected species. Improved seasonal and long-range forecasting provides an opportunity  to anticipate changing conditions, and alongside new management strategies, these tools are being developed to help build resiliency within coastal communities.
