This is the fifth in a series of extreme sea level rise maps. The other four so far are Los AngelesSeattlePortland, and San Diego.

This will happen someday, but not in our lifetimes. Some who have dared to speculate on a timeline have given themselves plenty of space for error in their predictions–one estimate says anywhere from 1,000 to 10,000 years. Whatever the time frame, anthropogenic climate change is a fact–humans are speeding up this process.

I am not portraying any sea level higher than what is possible. Because I want to create compelling images, each of the maps I’ve made vary somewhat in amount of sea level rise. The USGS has estimated that the total rise would be about 80 meters.

From the Washington Post, October 14:  Oceans experiencing largest sea rise in 6,000 years, study says 

Reconstructing 35,000 years of sea fluctuations, the study, which researchers say is the most comprehensive of its kind, found that the oceans are experiencing greater sea rise than at any time over the last 6,000 years. “What we see in the tide gauges, we don’t see in the past record, so there’s something going on today that’s wasn’t going on before,” lead author Kurt Lambeck, a professor at Australian National University, told the Australia Broadcasting Corporation. “I think that is clearly the impact of rising temperatures.”
