Sea level rise caused by climate change means increased and higher levels of flooding, especially downtown.  Skyscrapers are already causing the land, especially downtown, to sink.  Climate change is increasing the frequency of 100-year storms to almost yearly events.  Drought is killing off the wetlands, so floods happen faster and go higher.  And more and more of the permeable land in SF is being paved over, leaving fewer places for floodwater to go.  All this adds up to high risk for frequent disastrous flooding downtown.  So why is SF building more skyscrapers?  The greatest challenge humans have ever faced is climate change.  Why are SF’s politicians and developers still acting like it doesn’t exist?
