The Vancouver Star anticipates problems:
METRO VANCOUVER – The combination of a king tide and a surging storm that pummelled parts of Vancouver’s iconic seawall Monday are symptomatic of what climate change and rising sea levels could mean for the region, according to an expert.
Oceanographer Susan Allen said that in coming years, the flooding seen in parts of Metro Vancouver’s waterfront could occur outside a “coincidence” like Monday’s heavy wind and rain that combined with the so-called king tides, which are nearing the end of their month-long peak in British Columbia.
“In the future we won’t have to have quite so high a tide at the time of a storm surge to get exactly what we had today because the water will be a little higher,” Allen said. “The important thing is “and.”
“If you get global warming and a big tide and a storm surge then we (have) problems.”
No argument there. Sent December 18:
As Arctic ice continues to melt, the world’s coastlines are going to be dramatically transformed. And with these changes will come a new assortment of dangers, exemplified in such recent weather disasters as Superstorm Sandy and Typhoon Bopha. Cities up and down the coastline of North America will need to start planning for such events with the certainty of “when,” not the ambiguity of “if.”
This means that a great many things will have to change. Urban planners can no longer assume a business-as-usual model when it comes to the impact of a transformed climate on major population centers. To avoid tragedies of Brobdingnagian proportions during the coming centuries, the world’s nations must prepare carefully and cooperatively. Infrastructure must be strengthened, emergency response mechanisms augmented, and worst-case scenarios prepared for; all these are expensive propositions, until you consider the alternative: gigadeaths on a scale dwarfing all of humanity’s wars combined.
