CIG Scientist Harriet Morgan to present in Washington Sea Grant/EarthLab event

Building Resilience to Sea Level Rise Through Science Innovation and Community Engagement

Date: Tuesday, May 11
Time: 12:30-1:30 p.m.


Harriet Morgan of the Climate Impacts Group will join Washington Sea Grant’s Ian Miller and Nicole Faghin in this virtual webinar to discuss their work as part of the Washington Coastal Resilience Project. They will delve into the hazards people living in Washington’s coastal areas face – ranging from nuisance flooding during King Tide events, eroding coastlines and wave damage – and how sea level rise is exacerbating these hazards. They will detail how incorporating sea level rise projections into the decision-making process will help Washington communities build resilience to coastal hazards, and how the Washington Coastal Resilience Project employed technical innovations and community engagement to rapidly increase the state’s capacity to support proactive local action on these hazards.

This virtual webinar is part of a series celebrating Washington Sea Grant‘s 50th anniversary of providing research, outreach, communications and education to Washington’s marine communities. EarthLab has partnered with Washington Sea Grant for a special three-part series that builds upon Collaborating Across Difference, an exploration in how individuals from different disciplines, communities or geographies come together around a common goal.


CIG launches new tool and webinar for climate-smart stormwater design

The UW Climate Impacts Group has released an online tool to help stormwater and wastewater managers in the Northwest design and operate with climate change in mind. Developed in collaboration with the City of Portland, City of Gresham and Clackamas County, all in Oregon — and building on previous collaborations in Washington State — the tool provides new localized projections of changing heavy rain events through the end of the 21st century.

Interested in learning more about how to use the tool? Join UW Climate Impacts Group scientists Harriet Morgan and Guillaume Mauger and King County’s Bob Swarner for an informational webinar in May. Morgan and Mauger will provide an introduction to the tool, and Swarner will describe how King County is using the projections in wastewater planning.

Most stormwater and wastewater systems are designed based on the assumption that heavy precipitation events are static or unchanging. Yet recent research has shown that Pacific Northwest rainstorms are projected to become more intense with climate change. Projected changes in heavy precipitation events could strain our stormwater and wastewater systems.

To help stormwater managers meet this challenge, climate researchers at the UW Climate Impacts Group and officials in local and city government in Oregon collaborated to develop a tool that will guide the design and operation of 21st century stormwater management systems. Users can hone in on the precipitation frequencies and durations that are most relevant to their specific needs, and results and graphics can be downloaded for later use. Some broad take-aways from the new projections:

  • Extreme events are projected to get larger nearly everywhere in the Northwest, with the largest changes expected in some of the wettest parts of the region (high elevations and windward slopes)
  • Shorter (e.g., one hour) precipitation durations show larger changes than longer (e.g. 48 or 72 hour) durations.

This project builds on collaborations between the UW Climate Impacts Group and local governments in Washington State, including: King and Thurston Counties, the City of Everett, and the Port Gamble S’Klallam Tribe. The tool shows precipitation data for Washington, Oregon, Idaho, and parts of British Columbia, California, Montana and more.

Dr. Snover to Give Virtual Briefing on Linking Science & Action

Director Dr. Amy Snover will give a Livecast briefing for Congressional staff and the broader community on Thursday, April 16, 9–9:45 a.m. PT. In her briefing, “Bridging the Gap Between Science and Decision-Making,” Dr. Snover will discuss the University of Washington Climate Impacts Group and Northwest Climate Adaptation Science Center’s programs and methods for advancing climate resilience in the Northwest. The briefing is sponsored by the non-partisan Environmental and Energy Study Institute. Dr. Snover will appear as part of the Institute’s Climate Adaptation Data Week, a briefing series focused on coastal climate adaptation data needs and applications.
