This time of year, there's usually a seasonal crispness in the air, along with changing leaves and area pumpkin patches.

But the warm temperatures Hoosiers are experiencing has made it seem more like summer than fall - and climate researchers are noticing, too.

In Indianapolis alone, temperatures on Halloween have ranged from 24 degrees to 82 degrees over the years. And climate change could be a factor in a slow warming trend seen in Indiana since 1970.

Climate Central Meteorologist Lauren Casey said warmer fall temperatures can also worsen certain health conditions.

"The extension of the allergy season can be a nuisance for some people who are sneezing and sniffling," said Casey, "but much more burdensome for people with other, more serious respiratory issues, like asthma."

Casey said warmer air also produces more frequent and heavier rainfall, which creates a favorable environment for mosquitoes.

The radical temperature differences from year to year have helped coin the phrase "Halloween Extreme" - and lately, they've taken the 'chill' out of trick-or-treating.

Another drawback of excessive rainfall and above-average temperatures is their effect on fall foliage. Brown County State Park in Nashville, Indiana, is a nationally known tourist attraction in the fall - with 20 miles of tree-lined roads.

The state depends on those tourism dollars, and is concerned about the economic impact of climate change. Casey said conditions have to be just right for the best sightseeing.

"Everyone enjoys looking at the fall colors, right?," said Casey. "But the timing, and especially the brilliance of the fall colors, are related to weather conditions. So, if we have these warm overnight lows, that's not conducive to those bright colors. We need cool, crisp overnight lows to get those really nice fall colors."

Brown County reports almost $62 million was spent on lodging, food and beverage, shopping and transportation in 2021 alone.

State officials in Maine are highlighting apprenticeships as a way to earn a living wage and contribute to the state's growing green economy.

They'll kick off the first-ever Youth Apprenticeship Week by exposing high school students to the numerous ways they can learn and earn in offshore wind energy development, passive home construction, aquaculture, and more.

Maine Department of Labor Apprenticeship Program Manager Kristine McCallister said 90% of apprenticeships turn into a job.

"Apprentices have a mentor and they're earning wages and they're earning pay increases as they go," said McCallister, "so it's a really great way to attract talent to Maine and to keep talent here."

McCallister said apprentices will earn $300,000 more over their lifetime. The state aims to add 75,000 more workers to the economy over the next five years by growing career training pipelines.

A report by the Maine Labor Climate Council finds the state can create tens of thousands of jobs by building a zero-carbon transportation system.

Workers will be needed to install EV charging stations, electrify school bus fleets, and potentially build a high-speed rail line from Bangor to Boston.

McCallister said new Mainers, like those studying with Portland Adult Education, are using apprenticeships to fill these roles and other clean-energy jobs.

"Those pre-apprentices just graduated and have interviewed with some of our apprenticeship programs," said McCallister, "so we're really hoping they're going to help feed that pipeline as this economy is booming in Maine in terms of the renewable-energy sector."

McCallister said some companies are even offering on-the-spot interviews and job offers this week. All apprenticeship events are listed on the Department of Labor's website.

Climate watchers are predicting this summer's temperatures may set records, which could aggravate some medical conditions.

A 30-year study of health records from more than 200 countries and territories suggests a connection between stroke and climate change. The online publication "Neurology" reported the growing number of global deaths and disabilities from strokes are linked to -- but not caused by -- climate change.

Dr. Ann Jones, stroke neurologist at Indiana University Hospital, said when the body feels extreme heat and sweat evaporates, hypercoagulation, or blood thickening, occurs, which increases the chance for blood clots. Winter weather can also produce an instinctive response.

"The cold makes us kind of react with our fight-or-flight kind of drive, and it makes our blood vessels close down or vasoconstrict," Jones explained. "That can raise blood pressure up and that can predispose you to stroke."

Jones noted an ischemic stroke involves a clogged artery preventing blood from flowing to brain tissue. A ruptured artery during a hemorrhagic stroke causes blood to travel outside the artery wall into the brain tissue.

The Centers for Disease Control and Prevention reported almost 43% or 3,500 per 100,000 Hoosiers died from a stroke in 2021. Indiana ranks 34th in the nation for the rate of strokes.

The Yale Center on Climate Change and Health found heat can increase the risk of a stroke. Recent global burden-of-disease studies found 2 to 5 million deaths per year are linked to extreme temperatures globally. And climate change can also indirectly impact health through poor water quality, air pollution and increased spreading of infectious diseases.

Jones maintained good health is a start toward prevention and recommends the Mediterranean diet; consuming less red meat for optimal well-being and getting 30 minutes of exercise five times per week.

"Some things are out of our control," Jones acknowledged. "But just taking care of yourself in the ways that we can; focusing more on vegetables, fish, and staying hydrated, working on blood pressure with that reduced goal of less than 130 over 80."

The study indicated more research could identify the impact of temperature change on stroke as a way to address health inequalities including the burning of fossil fuels, deforestation and industrial processes.

Overnight in early July last year, Vermont solar installer Bill Chidsey got a call that a grocery store he worked with in his village of Hardwick was flooded. He arrived to find feet of water in the Buffalo Mountain Market's utility room, spilling over from the rising Lamoille River in a record-breaking rainstorm.

"The grocery store survived by an inch," Chidsey said. "If it had rained fifteen more minutes, they'd have lost four compressors."

He's now helping the co-op build a net-zero energy system that will use solar power and recycled waste heat from the store's refrigerators. But it's going to be a long project - just one of countless examples Vermont has seen since last year of how sustainable rebuilds in the wake of a flood don't happen quickly.

"I think we're just getting started with this," Chidsey said.

Advocates, utilities and state agencies have seen slow progress and mixed success since July 2023 in trying to replace flood-damaged home and business energy systems with more efficient, cost-effective, low-carbon technology. Now, they hope to redouble these efforts as part of a long-term recovery - both to keep people affected last year from falling through the cracks, and to be more resilient in the next storm.

"We consider that we're now about to start 'phase two,' where we hope to go back and talk about energy systems," said Sue Minter, who leads Capstone Community Action in central Vermont. "In the emergency - with winter and nowhere else to go, and oh, by the way, no contractors available, labor shortage, material shortage, crisis - we couldn't do the transition work, but that doesn't mean we won't."

Lessons from storm Irene

More than a decade ago, Minter was the deputy secretary of Vermont's Agency of Transportation when the 2011 Tropical Storm Irene - comparable in its severity to the 2023 floods - washed out hundreds of miles of roads and bridges across the state.

As the state's Irene Recovery Officer, Minter spent the next two-plus years grappling with federal regulators and pushing through new policies and programs to rebuild "stronger, with resilience in mind," she said. This included allowing easier upsizing of culverts and clearing development out of floodplains.

Many places with these post-Irene resilience upgrades and reforms saw less damage in the July 2023 floods as a result, Minter said. Vermont officials even came to a recent meeting of the Maine Climate Council, after a pair of weather disasters there, to talk about their approach to flood-resilient infrastructure.

"When you know you're in an emergency, and you know everything has been destroyed, you also know it's an opportunity to innovate ... to rebuild differently," Minter said.

Vermont, often called a potential haven for future climate migrants, is nonetheless seeing more frequent and intense rain and floods as one of its top impacts from human-caused climate change. The state also relies heavily on pricey, carbon-intensive heating oil.

After last year's floods, Vermont leaders wanted to seize the moment to help affected residents make future-looking energy and efficiency upgrades on a widespread scale.

"They're ripping out drywall, they're having to update systems - this is the time to make sure that you do it properly," said Efficiency Vermont supply chain engagement manager Steve Casey.

Making emergency rebates accessible

Efficiency Vermont, a statewide energy efficiency utility, created an emergency flood rebate program for affected homeowners and renters, reallocating $10 million in pandemic aid already set aside for low-income weatherization projects.

The new program offered up to $10,000 per household to repair or replace flood-damaged energy systems and other appliances, on top of existing funding for efficient electric heat pump water heaters and electrical panel upgrades. Similar rebates for damaged businesses were just raised to a $16,000 cap.

But uptake on this funding has been slow. As of January, only 155 households had received flood rebates of $5,100 apiece on average, according to state legislative testimony from Efficiency Vermont director Peter Walke.

It's partly because the initial $10 million was "an overshoot to ensure we wouldn't run out of funds," allocated quickly "without knowing what the actual need would be," said spokesperson Matthew Smith.

But people also ran into myriad barriers to using the money quickly.

Some lacked up-front cash to pay for upgrades that would be rebated later. In response, Efficiency Vermont has begun offering a 100% cost-coverage program for the lowest-income clients, where contractors are paid directly by the state. That program had paid out nearly $92,000 to 10 people as of January, per Walke's testimony, with 58 more in the pipeline.

"The households that are still in significant need at this stage were vulnerable households to begin with," Casey said. "We do have this repeating situation where flood events kind of just exacerbate some vulnerabilities for certain households."

'Life and safety first'

The timing of the 2023 floods was another complicating factor. The upcoming heating season loomed in the months after the disaster, and limited housing stock meant people couldn't relocate from damaged homes, unlike after Tropical Storm Irene, said Sue Minter.

"In 2023, July, people had to get into their homes as quickly as possible," she said. "You always have to have life and safety first."

The repairs and retrofits needed most urgently were not simple. Many people's water and space heating systems and electrical panels were in basements, "the first place to flood," said Casey.

Parts of Vermont are trying to change this norm - Waterbury, for example, requires basements to be above flood elevation in new or substantially improved home construction, among other flood protections.

Chidsey, the solar installer in Hardwick, said he and his electrician have tried to shift to putting electrical panels on the outside of homes, with any indoor subpanels out of the basement. Ideally, he said, the cellar becomes "just a hole in the ground that holds up the house, because water comes in often now."

But moving HVAC infrastructure out of a vulnerable basement, whether to meet a local requirement or voluntarily, isn't easy, especially after major damage, Casey said. People may not have a ready space for that equipment on the first floor, or may need mold remediation before taking on serious flood-proofing.

It means that the advocates working to facilitate upgrades have had to take a long view.

'The promise that we'll be back'

Last fall, Efficiency Vermont, Capstone, the state's utilities and a range of other partners stood up a new system of Vermont Energy Recovery Teams, who went into damaged homes to help people plan and prioritize repairs before winter, including coordinating holistically across contractors and funding sources.

Some homes were able to switch straight to heat pumps as a cheaper, cleaner method of water and space heating, officials said. But for many, a replacement oil or gas system was the simplest short-term option.

Efficiency Vermont does not normally offer incentives for installing fossil fuel systems, but made exceptions for high-efficiency Energy Star-rated models as part of its flood recovery rebate program.

"In every case, we looked for something that was more efficient than what they had before," said Vermont Gas energy innovation director Richard Donnelly, who was part of many recovery team home visits.

In each of those visits, the teams would take note of residents' long-term needs and goals for decarbonization, resilience, comfort and lower energy burdens, with an emphasis on heat pumps.

"We left off with sort of the promise that we'll be back," said Vermont Gas CEO Neale Lunderville - that "there's money available for some of these technologies, that we can help you with the same process."

The recovery teams are now under the umbrella of GreenSavingSmart, a pilot energy and financial coaching program for low-income residents run by the Vermont Community Action Partnership. They'll soon begin revisiting last fall's clients to facilitate a new round of resilient improvements.

"In the grand scheme of things, it's a hopeful pathway to allow these households to have - once they're fully made whole and recovered from all of this - a lower energy burden and cost burden than the situation they were in to begin with," said Steve Spatz, an account manager on the supply chain team at Efficiency Vermont. "It really is an opportunity to ... upgrade the conditions for the household."
