Schools And The Delta Variant, Doubts For High-Tech Air Purifiers. Sept 3, 2021, Part 1

Nation Grapples With Several Climate Disasters At Once

Hurricane Ida wreaked havoc on the eastern U.S. this week. It all started in Louisiana, leaving daunting damage and a long road to recovery for residents.

Even though Ida was downgraded to a tropical storm after leaving the state, it left a trail of destruction through the eastern U.S. and mid-Atlantic, flooding cities and damaging homes. In the New York area, at least a dozen people died after the region was pummeled by more than half a foot of rain in just a few hours.

This happened all while the western U.S. continues to battle wildfires, from Oregon to Colorado. In California, the extreme wildfire season led the state to close its National Forests through Labor Day weekend, a time where many people get outside and enjoy nature.

If it feels like these apocalyptic-level events are happening more and more frequently, you’re correct. Extreme weather is inextricably tied to climate change, and the science backs that up.

Joining Ira to talk about these climate stories and more is Maggie Koerth, science reporter for FiveThirtyEight based in Minneapolis, Minnesota.

Florida Schools With Mask Mandates Lose Funding

The state Department of Education said Tuesday it was investigating the school districts of Hillsborough, Sarasota and Orange counties over mask mandates that do not allow for a parental exemption. In a letter to district officials, Education Commissioner Richard Corcoran wrote the districts were in violation of a state Department of Health emergency rule triggered by Gov. Ron DeSantis’ executive order intended to block districts from enacting school mask mandates.

On Friday, Leon County Circuit Judge John Cooper ruled the executive order was unconstitutional and cannot be enforced. However, DeSantis said an appeal is planned and his office has said it will continue to act in defense of parents’ rights until a signed judge’s order was issued.

Corcoran’s letters were sent Friday, and the three districts were given until 5 p.m. Wednesday to respond. If they remain noncompliant, they could face financial penalties. All three counties have mandates that allow exemptions only for medical reasons with a medical professional’s note.

Back to School During The Delta Variant

Back-to-school is usually an exciting time, with some nerves mixed in. But this year is a little different. All across the country, arguments about mask mandates are exploding in school board meetings and courtrooms. In places with no mask mandates, parents are weighing difficult decisions over how much risk is too much.

But masks are just part of the equation for school safety. Air ventilation and distance are both important parts of the COVID-19 transmission equation, and many parents have questions about how their schools are preparing.

With pediatric COVID-19 cases rising, and Delta’s high transmission rates, many are wondering how we’re going to keep our kids safe in schools. Joining Ira to mull over this question is Dr. Katelyn Jetelina, assistant professor at the University of Texas School of Public Health in Dallas, Texas.

Many Schools Are Buying High-Tech Air Purifiers. Do They Actually Work?

As students head back to school, parents are getting a lot of mail about what schools are doing to better protect kids in the classroom—from mask policies to spacing to lunch plans. One item on many administrators’ lists of protective measures is improving classrooms’ ventilation.

Many studies have shown that better ventilation and air circulation can greatly reduce COVID-19 transmission. But rather than stocking up on HEPA filters, some districts are turning to high-tech air purification schemes, including untested electronic approaches and airborne chemicals.

Christina Jewett, a senior correspondent for Kaiser Health News, has written extensively about school air filtration and purification. She joins Ira to explain why some air quality experts are less than convinced by the marketing claims made by many electronic air purifier companies.
