Sea Level Rises
One of the chief global concerns with climate change is sea levels rising (melting polar caps and all). Since 1850, the Bay has risen a total of 7 inches. Best estimate based on expected climate change effects predicts a rise between 12 and 36 inches by 2100. That’s 2.5 to 8 times the expected rise rate. 1 to 3 feet doesn’t sound like much, so why be concerned? With the accelerated sea level rise, storm surge flood events are also to increase as well….as much as 10 fold.

In that scenario, check out good ol’ SFO:

Takeaway:
First and foremost, we’re not going to wake up and see SFO underwater. Though after some experiences there, that wouldn’t make me so sad. In reading the report, the most striking item is the uncertainty in sea level rise. Scientists just plain don’t know. What is true, sea level rise along with greater El Nino incidence = greater chance of flooding. And flood damage is the real headache.
