ONE TOWN SQUARE: at the intersection of peak oil, climate change, and land use

Recently the media have given a lot of coverage to a supposed new scientific consensus that sea levels will rise by about one meter by 2100. For example, this is from a story in Physorg.com:

Recent studies agree that sea level will rise by roughly one meter over this century for a mid-range emission scenario. This is 3 times higher than predicted by the IPCC.

New research from several international research groups, including the Niels Bohr Institute at the University of Copenhagen provides independent consensus that IPCC predictions of less than a half a meter rise in sea levels is around 3 times too low. The new estimates show that the sea will rise approximately 1 meter in the next 100 years in agreement with other recent studies. The results have been published in the scientific journal, Geophysical Research Letters.

But it’s not that simple, as this chart posted at Climate Feedback shows:

As you can see, the lower range of estimates of sea level rise are converging at around one meter. The upper range of the latest estimates is now hovering around two meters.  And it seems that every year, as scientists’ understanding of ice sheet dynamics grows, estimates of future sea level rise are growing as well.

You’d think people who live along the coast would be beginning to get a little concerned, wouldn’t you?  Think again.

From Florida, Mark Schrope reports that coastal development continues virtually unabated in Miami in spite of its vulnerability:

Right now Florida is showing almost no leadership on responding sensibly to storms and to rising sea level,” says Robert Young, a coastal geologist at Western Carolina University in Cullowhee, North Carolina. Orrin Pilkey of Duke University in North Carolina, a well-known proponent of greater constraints on coastal development, is even more forthright. “I call it an outlaw state,” he says. “Florida has been particularly irresponsible and it’s going to pay the price very soon.

As Climate Feedback points out, worse than just ignoring the threat of sea level rise, the state of Florida has taken drastic action to ensure that waterside properties damaged in storms can be rebuilt in the same locations time and time again.

Here in Oregon, plans by the City of Newport to redefine areas prone to landslides and erosion and to impose new rules governing how construction can occur in them are raising the outrage of property owners. Oregonlive reports:

Property owners here are furious over city plans to redefine areas prone to landslides and erosion — and how construction can occur in them.

Proposed building code changes for new construction in areas known as geologic hazard zones will cost property owners billions of dollars, they say, and are bound to trigger lawsuits.

Talk about the changes began circulating town this month. Angry locals swamped a Planning Commission meeting and quickly formed the Central Coast Home and Business Owners Association to fight the changes, which they accuse Newport officials of trying to sneak in.

At the heart of the battle is the city’s plan to adopt maps made by the Oregon Department of Geology and Mineral Industries in 2004. The maps show landslide and erosion zones, coding them in red, orange and yellow according to the degree of risk. Red is the highest. . . .

Opponents say the changes are naive and wrongheaded — and will cost everyone. They fear that under the changes, existing buildings in red zones would become “nonconforming” uses, making them nearly impossible to refinance, sell or insure.

The city has backed off some of the most controversial proposals, and “further revisions are likely.”
Better an inevitable “natural” disaster than what development interests call an “economic disaster.” In Oregon, as elsewhere, it seems our approach to an unpalatable situation is to bury our heads in the sand. Until we drown.
