Washington sea level rise: How much will your city go under water?

A study released last month by a coalition of groups led by the state Department of Ecology and Washington Sea Grant contains data showing just how screwed we are if we allow current rates of greenhouse gas emissions to accelerate sea level rise on Washington state's expansive coastline.

But it requires deep reading and some fluency in climate science to understand the data. If you like, you can upload two-page Excel data sheets for each of the 171 sites for which projections are given:

However, we broke down some of the more digestible information for you in the gallery above.

The information is intended to give city and state planners an idea of what's to come so they might prepare our coastline communities for the inevitable changes to come.

Ecology's latest data accounts for new factors that weren't incorporated in previous projections, namely how tectonic shifts can shift land vertically and thereby actually force a slight sea level recession in many locations.

Additionally, the study gives a view of what sea level change might look like at different probabilities, from what's 99 percent likely to 0.1 percent likely. Those probabilities are given for several different years until the year 2150.

The data also compares how sea level rise might differ in a "business as usual" model -- basically, if we were to continue our current rate of greenhouse gas emissions -- versus how it might look if we enact aggressive reductions in our greenhouse gas output.

We pared down the data to the "business as usual" rate and selected some milestone years, giving a range from what's 99 percent likely -- typically a lower sea level rise -- to the extreme view of the 0.1 percent chance. We present that for a handful of key locations on our Puget Sound, Hood Canal, Strait of Juan de Fuca and Pacific coasts.

Sea level increases and decreases are given in feet.
