A 2017 disclosure by San Francisco reads: «The city is unable to
predict whether sea level rise or other impacts of
climate change or flooding from a major storm will occur, when they may occur, and if any such events occur, whether they will have a material adverse effect on the business operations or financial
condition of the city and the
local economy.»
In particular, many of the plant populations
predicted to persist in the near future will actually do so under
local climate conditions that are already unsuitable for their long - term survival because long live spans and clonal reproduction strategies of many high mountain plants allow them to retard extinction.
