Sea level rise underestimated, say B.C. scientists
The gathering of the American Association for the Advancement of Science heard Sunday the sea level could rise by as little as 30 centimetres or as much as one metre in the next century.
But SFU geology professor John Clague, who studies the effect of the rising sea on the B.C. coast, says a rise of about one metre is more likely.
He said that’s serious enough to threaten the communities of Richmond and Delta, including homes, Vancouver’s international airport, Deltaport and theTsawwassen ferry terminal.
“We’re going to see people either defending property, spending tremendous amounts of money trying to defend coastal properties, or we need to relocate the peripheries of our cities to higher elevations,” said Clague.

There has been little or no sea level rise in Vancouver over the last century.
The “could” crowd don’t deserve any attention any more; they haven’t deserved any from the start; it’s all rather Ehrlich-esque.
Just returned from a very cold Amsterdam. No tulips and lots of frozen small canals. Considerable ice on the Zuider Zee and even sea ice on the North Sea side of the dike.
Amazingly, no frantic efforts to protect against sea level rise; not a JCB, tractor or truck in sight. Bet North Holland and the rest of the Netherlands is lower and flatter than BC.
“or we need to relocate the peripheries of our cities to higher elevations”
What’s this “we” stuff? People will relocate themselves as they perceive a need to. Collectivist action not required.
If 30 cm rise is okay, but 1m is not, and it will rise 1m in 100 years, that means they have 20 to 30 years to see what is actually happening. Again, no action required. For at least a generation.
That one meter rise will happen in a single day, when they least expect it. SLR is verry Tricksy! Donchano!

Vancouver is run by a cabal of youngish Eco Greenies, lead by Mayor Moonbeam and financially backed by Tides Canada. The have buckets of money and loads of self inflicted Warmista beliefs.
They just spent $700k on an “art project” to paint lamp posts and bridge supports around False Creek with 1m blue bands, each indicating the projected sea level rise and trying to scare people into supporting the AGW fantasy fearmongering campaign.
Nice people but terminally stupid.
Revocation of credentials please.
Reblogged this on Climate Ponderings.
Don’t blame ocean rise on any potential future flooding of the area and/or the cost of future flood protection. The dikes around Richmond and Delta, constructed to prevent flooding and alow major city development, where there should have been mostly farms, force the Fraser river to carry its sediment load out into the Strait of Georgia so that none accumulates on deltaic lands. The delta is sinking one to two milimetres each year under its own weight. I am sure there are equivalents in the US.
More importantly, what the honourable professor does not say, but should worry about most, is that the area is in an active seismic zone and as a consequence of seismic liquefaction structural destruction is the real danger here, not the ocean rise.
Equivalent deltas in the US would be (famously) the Mississippi delta in Lousiana and (not so famously), the Sacramento/ San Joaquin delta in California.

Should’ve added; like in Mississippi, in California, the levees are protecting areas below sea level. In an earth quake, the entire levee network could liquefy and collapse, causing vast flooding.
When discussion with people living along the coast of northern Sweden they claim that after 30 year it is clearly visible to see the change (we now talk about 9 mm rise per year of LAND not Sea).
They would not mind getting their old beaches back (Since they now are mainly dry land).
Now if this is clearly visible after 30 years then there must be places in the world where the claimed sea rise of 3 mm per year also should be visible (since the 3 mm is on average and some places must have more than 3 mm per year some less), but I have not seen any such evidence.
“…We’re going to see people either defending property, spending tremendous amounts of money trying to defend coastal properties, or we need to relocate the peripheries of our cities to higher elevations,” said Clague…”
…or, we’ll see a lot of people laughing at them because nothing happened. And that would be a real travesty!
If you really want to get people in your neighborhood wondering, start building a 1 meter levee around your property, and tell them it’s because the climate scientists say rising sea levels are gonna happen soon – and drop NASA scientist James Hansen’s name as the “source”.
Even better if you happen to live in Kansas.
