Sea level rise over the next century will inundate portions of coastal states, requiring some kind of adaptation from local populations. In this talk, John Callahan of the Delaware Geological Survey shares the sea level rise projections he has developed for the state, and Phil Barnes, of the Institute for Public Administration in the Biden School of Public Policy, addresses options communities have to deal with rising waters.

Dr. Callahan's Areas of Expertise

- Expertise in climatology, meteorology and storms, sea-level rise and climate change, tides and coastal flooding, remote sensing, GIS, geospatial and time series statistics.
- Research projects include storm surge from tropical and extra-tropical cyclones in the Delaware and Chesapeake Bays; dendrochronology of Atlantic White Cedar trees; habitat identification of Delmarva Fox Squirrel; atmospheric water vapor over the Amazon Rainforest from satellites; and development of coastal flood early warning system.
- Serves on the Delaware River Basin Commission Advisory Committee on Climate Change.
- Lead author of Recommendations of Sea-Level Rise Planning Scenarios for Delaware: Technical Report.

Curriculum Vitae

Philip’s research focuses on local climate change adaptation planning and implementation, with an emphasis on flooding and sea level rise mitigation. He also conducts research on non-traditional transportation policy such as bikeshare networks, electric vehicles, and autonomous vehicles. Philip works closely with state agencies on applied research to enhance local community resiliency.

Sussex County is #3 among coastal counties for building the most homes in the highest-risk areas,

$500M homes built on vulnerable land in Sussex County since 2010.

Homes built in DE are 2.6 times faster in flood zones than non-flood zones.

38-78% of Delaware's dams, dikes and levees may be inundated by SLR by 2100.

Flood claim denied for restaurant turned 'basement' after Miami Beach raised street

Questions:

Does the beach replenishment artificially change the shoreline in the long run and also delay the effects of the sea level rise? Why should the taxpayers keep funding the lifestyle of people who choose to live in the flood-prone areas?
If FEMA is providing all fund to buy out homes, what incentives are there for local governments to not encourage expensive homes in the water-front areas to increase their tax base?
Isn't it predictable that the local governments would offer only the less expensive towns for buyouts so that they still collect higher property taxes from expensive areas while they survive?

Icy Seas off Greenland: Scientific Musings of a Sailor in a Changing Climate

Lecture by Dr. Andreas Muenchow - 8/20/2020

Andreas Muenchow describes his experience sailing the coastal waters of northern Greenland for over 20 years. In Muenchow's words, "While oceans, sea ice, and glaciers have much changed over time as have sensing technologies and global climate modeling, ships and sailors still extract truths not accessible by satellites and computer codes. Field work in a cold and hostile place of stunning beauty humbles the observer when nature’s plan differs from that of the sailor as it often does.

High salinity brings the freezing point down to 29 degrees F from 32 of fresh water. As going down the ocean depth, salinity gets higher and the temperature stays stable, often warmer than the surface where the ice melts.

About an hour into the lecture, Dr. Muenchow explains the speed of glacier melting and the sea level rise. When the ice melts, it immediately forms a shielding blanket around the bottom of the iceberg preventing it from melting further. However, the ocean currents and forces stir up the blanket and remove it, then the ice melts again.
