With Storms, Humidity, Comes Toxic Mold

Women’s Health:

As climate change is predicted to increase global temperatures, humidity, and rain, researchers studying the public health effects of mold and chemical intolerance say the associated water damage (via flooding and humidity) will potentially make mold illness more prevalent. (Of note: Lower-income residents are especially at risk for water damage and mold-health problems, as they’re more likely to live in poorly constructed homes in low-lying areas, and have less money to repair mold-damaged homes, per Peccia’s research.)Harvard University researchers are also exploring how changing weather patterns could make certain wood-framed residential buildings found in places like Philadelphia and Washington, D.C. more susceptible to mold growth in the future.

“We’ve built buildings based on a narrow definition of historic climate,” says Holly Samuelson, DDes, an associate professor of architecture at Harvard Graduate School of Design who researches the impacts of building design on human and environmental health. “What’s going to happen when climates shift?” 

Rick Bayless, an environmental home health investigator in the southern Appalachians, says he’s already seeing an increasing number of damp homes and mold growth due to rain events. 

“Buildings can’t keep up with weather conditions they weren’t built to address,” Bayless says. “We need better building guidelines.”

Right now, he says, building codes don’t do much to protect people who are environmentally sensitive.

More Carolina Houses Swallowed by Rising Seas

As the pace accelerates, the homeowners wealthy enough to own these houses will call for Taxpayers to shore them up or insure them, which is happening in some cases.

Town of Kure Beach, North Carolina:

The last beach nourishment project was in March of 2022. Beach nourishment is officially referred to as Coastal Storm Damage Reduction or CSDR .

PLACEMENT OF SAND

The decision about where and how much sand to put on the beach is based on how the beach area holds up during storms and the amount of erosion since the last nourishment. Purpose of the sand placement is to protect the integrity of the infrastructure of the town and mitigate property loss during storms. The beach is measured and compared to previous nourishments. History shows that sand typically leaves and returns to most areas of the beach in between nourishments. The sand placed on our beach comes from the bed of the Atlantic Ocean.

HISTORY

In 1995, the town entered into a 50 year contract with the US Corps of Engineers (Corps) for placement of sand on the beach every three years. At that time, the areas of Hanby and Wilmington Beach were not annexed into either Carolina or Kure Beach, therefore the project was referred to as ‘Carolina Beach and vicinity area south’. The Corps makes the decision about where and how much sand to put on the beach.

Historically, sand has been placed in two areas:

  • N. Carolina Ave in Carolina Beach to Myrtle Ave, at the northern town limits of Kure Beach
  • Davis Road to Camp Wyatt Ct, at the southern town limits, to Building 18 of the Ocean Dunes complex

FUNDING

Funding for these projects is 65% from the Federal government, 17.5% from the State of N.C., and 17.5% from the Room Occupancy Tax (ROT) fund. ROT is a 6% tax that hotel and vacation rentals must charge and remit to the county. No Kure Beach property tax dollars are used for nourishments.

Two Small Modular Reactors: How Are they Working?

Fuel loading at the Shidaowan high-temperature gas-cooled modular pebble bed (HTR-PM) in China began in the spring of 2021. It involved putting 870,000 spherical tri-structural isotropic (TRISO) particle fuel elements into the two small reactors that will drive a single 210-MWe turbine. Courtesy: China National Nuclear Corp.

Once again, given the resources that are going in to deployment of Small Modular Reactors around the world, we can only hope that they succeed – the stakes are high.
That said, it might be useful to review the actual operational experience so far with the only SMRs that have yet been deployed.
PowerMag has a detailed review, excerpted here, much more tech specs at the link.

PowerMag:

Many nuclear power supporters have long thought small modular reactors (SMRs) would revolutionize the industry. Advocates expect SMRs to shorten construction schedules and bring costs down through modularization and factory construction. They often cite numerous other benefits that make SMRs seem like no-brainers, and yet, only two SMR designs have ever been built and placed in commercial operation.

The International Atomic Energy Agency (IAEA) publishes booklets biennially on the status of SMR technology. In the IAEA’s most recent booklet, it notes 25 land-based water-cooled SMRs and another eight marine-based water-cooled designs are under development globally. It also lists 17 high-temperature gas-cooled SMRs, eight liquid-metal-cooled fast-neutron-spectrum SMRs, 13 molten-salt SMRs, and 12 microreactors. If you do the math, that’s 83 SMR designs under development, but only the KLT-40S and HTR-PM are actually operational.

KLT-40S

The KLT-40S is a pressurized water reactor (PWR) that was developed in Russia. It is an advanced version of the KLT-40 reactor, which has been used in nuclear-powered icebreakers. The first KLT-40S units, and, to date, the only two of these units to enter commercial operation, were deployed in the Akademik Lomonosov—the world’s first purpose-built floating nuclear power plant (FNPP, Figure 1).

Akademik Lomonosov was fully commissioned on May 22, 2020, and it currently provides heat to the town of Pevek and supplies electricity to the regional Chaun-Bilibino power system.

Helene’s Worst Impacts Could be Inland

The Carolinas are still drying out from recent “No Name” storm that dropped “1000 year” rain totals along coastal areas.
Helene could bring heavy rain to mountainous areas highly vulnerable to flash flooding and landslides.

Categories are Meaningless, Helene is a Monster

If this summer has shown us anything, it’s that a storm doesn’t have to be even developed enough to be named, to have major destructive, climate juiced power.

Helene, though, is the real deal, and will deliver a blow across a wide area that is still recovering from this summer’s flooding.

Detailed post is at Michael Lowry’s Eye on the Tropics, excerpts here.

Michael Lowry – Eye on the Tropics:

Helene continued to steadily strengthen as it grazed the northeastern tip of Mexico’s Yucatán Peninsula Wednesday morning. The storm is on the cusp of becoming Hurricane Helene and is projected to deliver a devastating blow to Florida’s Gulf Coast tomorrow as a major hurricane.

Forecasts have been strikingly consistent showing a major hurricane (Category 3 or stronger) landfall in Florida’s Big Bend between Mexico Beach to the west and Cedar Key to the east. The official forecast takes the center of Hurricane Helene inland just south of the state capital at Tallahassee between St. Marks and St. George Island as a Category 3 hurricane Thursday night or very early Friday.

Helene is forecast to be a remarkably large hurricane, with tropical storm winds extending nearly 430 miles across as it nears Florida tomorrow.

Only four named storms this century have been as large as Helene is forecast to be over the Gulf of Mexico: Irma (2017), Ike (2008), Ivan (2004), and Isidore (2002).

Is Geothermal Ready to Rock?

I’ve posted recently on the efforts, through various schemes, to jump start nuclear power. I do wish them luck.

That said, nuclear will face keen competition, not only from cheap-and-getting cheaper solar, wind and batteries, but often ignored Geothermal technology, which is right now reaching the place where fracking was in about 2007, where solar was in about 2014, and where batteries were about 2 years ago – in other words, poised, perhaps, for a major, market changing breakout.

Economist:

 Geothermal Energy may be approaching its Mitchell moment. George Mitchell, a scrappy independent oilman, is known as the father of fracking. Nearly three decades ago, he defied Big Oil and the conventional wisdom of his industry by making practical the hitherto uneconomic technique of pumping liquids and sands into the ground to force out gas and oil from shale rock and other tight geological formations. The enormous increase in productivity that resulted, known as the shale revolution, has transformed the global hydrocarbon business.

Now Fervo Energy, another scrappy Texan upstart, is applying such hydraulic fracturing—alongside other techniques borrowed from the petroleum industry—to the sleepy geothermal sector. Should it succeed, it would mean this relatively fringe source of energy could, in time, become a major player in the energy mix.

The motivation behind geothermal energy is to harness Earth’s abundant subsurface heat for useful ends. This is ordinarily done by tapping into underground reservoirs of hot water or steam. As these are only found in limited areas, this greatly limits the potential of conventional geothermal power. In contrast, “enhanced geothermal systems” (egs), like the one deployed by Fervo, use hydraulic stimulation to create channels in hot rocks just about anywhere. One well pumps in water into those channels, where it is heated naturally to 200°C or higher. Another well then brings that hot water to the surface, where it is used to generate electricity in a turbine.

Is Transition Hope Fading?

Happy Climate week.
Hope you’re planning to vote.

Wall Street Journal:

Climate optimism is fading. Higher costs, pushback from businesses and consumers, and the slow rollout of technology are delaying the transition from fossil fuels.

Renewable energy is growing faster than expected. But surging demand for power is sucking up much of that additional capacity and forcing utilities to burn fossil fuels, including coal, for longer than expected.

With greenhouse-gas emissions continuing at record levels, scientists expect floods and heat waves to get worse. This year is on track to be the hottest on record.

“The pace of our response is obviously totally insufficient,” said Sonia Seneviratne, a climate scientist at Swiss university ETH Zurich. On this trajectory, “it will become increasingly impossible to face the changing climate we are going to experience,” she said.
