Impacts of a Changing Climate on Wetland Ecosystems

April 27th, 2020

Presenter Slides


This webinar will review the potential impacts of a changing climate on wetland ecosystems, with a focus on the glaciated northeast. The presentation will review three types of wetlands: vernal pools, peatlands and tidal marshes with an eye to the vulnerability and potential resilience of such systems to the current and projected changes is temperature, precipitation and atmospheric carbon dioxide content. Response of these ecosystems to such disturbances will be considered through different spatial scales.


Presenter: Prof. Michael Simpson has graduate degrees from both Dartmouth College and Antioch New England Graduate School where his focus of studies was wetlands ecology and economics.

He has been a senior environmental scientist, and partner, for two environmental consultant firms in the Northeast. He has also worked for both the NH Dept. of Environmental Services and the MA Dept. of Environmental Protection.

He is a licensed wetlands scientist with over thirty-years of experience in wetland and riparian corridor assessments. He has also designed created-wetlands to mitigate both wastewater and non-point source pollution. These projects have been accompanied by economic cost/avoided cost analyses related to decisions regarding resource utilization and conservation.

Currently, he is the Director of the graduate Resource Management and Administration program, within the Environmental Studies Dept at Antioch University New England, and Co-Director of the Center for Climate Preparedness and Community Resilience. Within the department, he has taught graduate level courses in wetlands ecology, watershed management, environmental site assessment and principles of sustainable systems.

His research has ranged from impacts to springs, seeps and wetlands from large groundwater withdrawal to multi faceted analyses of the vulnerability of stream-road crossings for both peak flow conveyance and aquatic organism passage. Research, funded by NOAA and the US EPA, focused on assessing the vulnerability of riparian corridors from a changing climate within the context of a changing landscape.

Upcoming Events


Policy Advocacy: Climate Change

This course will provide participants with step-by-step skills in utilizing the tools of democracy to take meaningful civic action on climate change. Participants will learn the levers for building political will and the essentials of climate change communication. You will apply your learning by taking action in collaboration with a local environmental organization, and further your learning with your peers via Antioch’s online learning platform and optional one-on-one meetings with the instructor.

Climate Impacts: Vulnerability and Adaptation Planning

Local and regional governments are leaders in climate change due to their unique position to make a wide range of decisions that can mitigate and adapt to our changing climate. Because they are on the frontline, many communities have conducted vulnerability assessments and engaged in adaptation planning. This module will enable participants to assess impacts to a business, community, or sector based on specific climate projections for a specific locale.

Climate Impacts: Communication, Facilitation, and Stakeholder Capacity Building

Collective actions at the societal level (civic or political action behaviors) include involvement and support of policies, plans, and funding for implementation of municipal projects that could increase local climate resilience. Community engagement with the issue of climate change typically is lacking at the local level. How individuals feel about climate change, how much they know about the issue, and how they act are all types of engagement that are needed for societal change.
