Here we go again! 2021: Unless we act on climate change, DC will be underwater – Flashback: Virtually same flood fears were reported in 2014, 1990, 1979, 1922 & 1901!

The Lincoln Memorial would eventually be on an island in the Potomac River, if world keeps burning fossil fuels.

The Lincoln Memorial, on an island surrounded by churning Potomac waters; Nationals Park, a bathtub surrounded by mid-rise office buildings flooded by the Anacostia River; the Pentagon, accessible by boat, with State Route 110 and the George Washington Memorial Parkway underwater.

These are images of the possible climate-change-induced future in D.C., if the world continues on its current trajectory of greenhouse gas emissions.

“The decision that we’re all making right now is which trajectory we’re going to take,” says Andrew Pershing, director of climate science with the nonprofit Climate Central. The group published a peer-reviewed research paper documenting the longterm threat that sea-level rise poses to the world’s coastal cities. As part of the project, the group generated images of at-risk cities around the globe, with projections of future sea-level rise, depending on emissions trajectories.

If the world continues on the current emissions pathway, we can expect roughly 3 degrees Celsius (5.4 degrees Fahrenheit) of warming by the end of this century. The Paris Climate Agreement aimed to limit warming to 1.5 or 2 degrees Celsius.
