INTRODUCTION

As you prepare to engage in this discussion, you are invited to take a Google Earth tour examining Sea Level Rise and the Fate of Coastal Cities (Links to an external site.), which includes short video animations. This will help you to visualize how much sea level rise will affect coastal communities under different future climate scenarios – one based on a 2 deg C temperature rise and the other based on a 4 deg C temperature rise.

This discussion consists of two parts:

PART 1 (DUE Mon. Feb. 7 for 20 pts):

Each group member should select ONE of the following locations and research answers to the following questions for that location.

Each group member must choose a different location from one another. In other words, if someone has already posted about Lagos, you should choose a different location.

It is recommended that you make an initial post with just your chosen location while you complete the research to answer the questions.

Some questions will require additional research beyond the Google Earth tour.

EXAMPLE: HERE IS A HYPOTHETICAL EXAMPLE POST THAT YOU CAN USE TO FORMAT YOUR RESPONSES TO PART 1.

LOCATION: Washington D.C.

Avg. elevation: 150 ft

Projected sea level rise:

6 ft rise with 2 deg C

10 ft rise with 4 deg C

This is what it will look like (Links to an external site.)(please include written description with supporting visuals/screenshots)

Population affected:

1,400 people displaced with 2 deg C

4,833 people displaced with 4 deg C

Most threatened industries: Government. According to Climate Central (Links to an external site.), “The District has 21 miles of road below 6 feet, plus 2 military facilities; 1 hospital; 1 museum; and 12 EPA-listed sites such as hazardous waste dumps and sewage plants. At 10 feet, these numbers grow to 46 miles of road, 4 military facilities, 1 hospital, 3 museums, and 26 EPA-listed sites.”

Existing Mitigation Measures: There is a levee around the National Mall. According to a report by the National Capitol Planning Commission (Links to an external site.), D.C. has inadequate storm sewer capacity to deal with flooding.

Historical Storm Surge Range: 12 ft (SOURCE: National Capitol Planning Commission (Links to an external site.))

Surprise Observation: The National Mall being flooding

PART 2 (THREE POSTS DUE Wed. Feb. 9 for 5 pts each = Total 30 pts):

Respond to three other group members’ posts, reflecting on ONE (or more) of the following:

What is a possible solution to mitigate future flooding in this location? What would be the estimated cost?

Where do you think people displaced by this flooding should go? What will be the estimated cost?

Is this location in an active margin or passive margin? What additional considerations might this invite in planning future flooding risks?

How does this compare to your own research in the location you chose?
