Extreme Temperature Diary-June 24, 2019/ Adaption… High Cost Of Pulling Back From Shores

Monday June 24th… Dear Diary. The main purpose of this ongoing blog will be to track United States extreme or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉

Adaption…High Cost Of Pulling Back From Shores

Today’s main subject is nothing new, having broached sea level rise many times on this blog. What is new are tremendous dollar signs attached to projects that should be planned to keep rising seas at bay because of the climate crisis, and how much poorer people will be affected by adaptation management plans. I’ve highlighted two articles I came across today that should give my readers a sense of what is at stake if global averages exceed the +2.0 C above preindustrial threshold most experts have agreed should not be crossed. Under the “moderate carbon pollution scenario” condition described in the articles price tags grow quickly, which might even be optimistic. That doesn’t mean that we should not give up trying to make green changes, though.

Here is some of the first Guardian article, which puts dollar signs on potential sea level rise:

Seawalls to protect US against rising oceans could cost $416bn by 2040

Seawalls could cost as much as the initial investment in the interstate highway system, with Florida facing $76bn, report finds.

Defending against rising seas could cost US communities $416bn in the next 20 years, according to a new report.

Spending on seawalls alone could total almost as much as the initial investment in the interstate highway system, the authors said. And the billions involved will represent just a fraction of adaptation efforts governments in coastal states will have to fund if they do not want to simply retreat.

“I don’t think anybody’s thought about the magnitude of this one small portion of overall adaptation costs and it’s a huge number,” said Richard Wiles, executive director of the Center for Climate Integrity (CCI), which published the report.

Estimates of how much sea-level rise will cost often focus on impacts by 2100, Wiles said, adding that people will be paying for the climate crisis much earlier.

“You’re looking at close to half a trillion spent over the next 20 years and no one has thought about that. So the question is, who’s going to pay for that? Is it really going to be taxpayers? The current position of climate polluters is that they should pay nothing, and that’s just not tenable.”

According to the report, Florida faces the highest costs, $76bn by 2040. Louisiana comes in second at $38bn and North Carolina third at $35bn. For cities, Jacksonville, Florida, New York and Virginia Beach could spend the most: $3.5bn, $2bn and $1.7bn, respectively.

Many places are starting to pay such bills. Staten Island in New York, for example, is planning a $615m, five-mile seawall to withstand a 300-year storm. The federal government will pay $400m.

As the planet heats up and land-based ice melts, the average global sea level has risen seven or eight inches since 1900, with about 3in of that rise occurring since 1993, according to a US government report. Seas could be up to 3ft higher by 2100 under the scenario examined by the CCI.

The CCI published the report with analysis by lead scientist Paul Chinowksy, director of the environmental design program at the University of Colorado Boulder and chief executive of the firm Resilient Analytics. Advertisement

The cost figures in the CCI report are based on localized projections for sea-level rise under the UN Intergovernmental Panel on Climate Change (IPCC) scenario for moderate levels of pollution. In that scenario, called RCP 4.5, emissions would peak around 2040 and then begin to decline.

The projections in the report were calculated by the climate science and news organization Climate Central.

The CCI report considered how much communities in the contiguous US would pay locally to build sea walls to protect against the storm surge expected in a given year, Wiles said, although many would spend more to build even stronger defenses.

Other communities might vanish rather than pay for new infrastructure. If so their governments could then be vulnerable to lawsuits from residents, Wiles argued.

Some communities examined would have to spend $1m a person on needed defenses, the assessment found. For example, Fire Island, a barrier island off the mainland of Long Island in New York, would face $1.5bn in investment to protect a few hundred ocean-front homes.

The group studied thousands of miles of coastline to determine where roads might be submerged. Researchers estimated the cost of defending vulnerable infrastructure within portions of shoreline that could be at least 15% underwater by 2040.

The next NPR article and interview stresses how much some of the poor among us will be affected by relocation away from rising seas or other climate crisis phenomena (Just click on the tweet to read.):

Manpower resources will obviously be stressed if these forecasts are correct. Let’s all prepare to work hard due to what looks like inevitable, costly change.
