Sea Level Rise – sponsored by Island County Marine Resources Committee

Sponsored by the Island County Marine Resources Committee (MRC), Ian Miller PhD of University of Washington presented to capacity crowds on both Camano and Whidbey Island explaining the causes and possible consequences of sea level rise due to climate change. One source of added water in the oceans is the melting ice above ground that is visible from year-after-year photos of Antarctica and Greenland. When this ice melts, since it wasn’t part of the ocean to start with, it adds volume. Furthermore, rising ocean temperatures mean the water is expanding.

Dr. Miller explained the uncertainty related to making predictions about the impacts, both in terms of when and by how much. For Washington waters, “There is a 50% assessed likelihood that sea level will be 2.1 feet or higher relative to present by 2100 if emissions track RCP 8.5.” RCP 8.5 refers to a ‘business as usual’(we make no changes) global scenario for Representative Concentration Pathway. Dr. Miller then compared that to RCP 4.5 (a pathway in which the world takes actions to reduce carbon emissions) for Island County which shows 50% assessed likelihood that sea level rise will be 1.8 feet.

After reviewing probability tables with the group, we then had the opportunity to look at possible scenarios for ourselves. MRC had outfitted the room with seven laptops, one for each table of participants. We viewed our local neighborhoods and beaches using the sliding scale on the left to see what was under water at 1 foot, at 2 feet of sea level rise and so on. [The Camano group noticed portions of Highway 532 in Stanwood would be under water at 1 foot of sea level rise.]

You too can use the Sea Level Rise online tool to see how the low areas get covered as sea levels rise. It is on a website managed by NOAA Office of Coastal Management. https://coast.noaa.gov/digitalcoast/tools/slr.html  When you arrive at the website you need to launch the application then put in a zipcode or street address. I encourage you to check it out.

Dr. Miller’s research is part of a coastal communities regional resilience project to help inform people who live on the shores. Sea level rise can contribute to coastal flooding (higher surges, more frequent flooding), habitat loss (loss of mudflats, marshes), salinity change which could affect wells and groundwater) and shoreline erosion.

Tim’s whitepaper (2013) to WSU Extension Director on proposed future scenario

E-mail from Barb dated May 14, 2013: [NOTE: a link to the whitepaper follows the email message]

Dear Beach Watchers,

Several months ago, Tim Lawrence, Director, WSU Island County Extension, presented the attached White Paper to the Director of WSU Extension.   While the original assignment was to consider the future of the Beach Watchers program, Dr. Lawrence took this opportunity to research university-based environmental programs across the country and develop suggestions for WSU’s environmental outreach statewide.  The Beach Watchers program is included in the broad, conceptual framework described in the attached paper.

 The paper has been well received and a committee has been formed, under Tim’s leadership, to define a way forward on the concepts and to develop a core environmental curriculum for outreach programs.  That committee has met 2 times and I am pleased to serve on the committee.

 This paper sets out themes that will likely shape the future of the Beach Watchers program and other WSU environmental outreach programs.  It invites the potential of strong and diverse statewide environmental outreach and sets the stage for exciting possibilities ahead.
