Earth Month in Indianapolis has gotten off to a wet start. In just a single day, April 2, the city received about half the rainfall it usually gets the entire month.

The rain event was a high point in precipitation that followed two months of below-average rain or snow, according to the National Weather Service. The same happened in January, when snow and rainfall broke a five-month streak of below average precipitation. Before that it was a three month streak. 

The city is also experiencing some of the highest temperature averages ever. This February’s average temperature was 8.7 degrees above average, the fourth-hottest February recorded in Indianapolis. December was the seventh-warmest on record.

IU Indianapolis biogeochemist Gabriel Filippelli and other climate researchers say the precipitation and temperature patterns are evidence that the climate in Indiana is changing.

“We often think of climate change as a big global thing that only happens to polar bears, but we’re actually feeling the impacts of climate change right here in Indiana and in Indianapolis,” Filippelli said.

Filippelli is the executive director of Indiana University’s Environmental Resilience Institute and was part of the Indiana Climate Change Impacts Assessment, a statewide effort to understand how climate change will impact the state over the next century.

He and the other researchers found that emissions from fossil fuels will heat the world enough to alter the climate, which, in turn, will affect almost every facet of life for Hoosiers, including the weather, health, agriculture, energy use and even tourism.

More rain and higher temperatures over the last 20 years have resulted in 15% more flooding events, Filippelli said, and contributed to a 400% surge in mosquito populations here. 

Climate change is even affecting the daily commute for Indianapolis residents. 

“The weather is so variable now in springtime that (the Department of Public Works) has a really hard time getting the right paving mix to fix potholes,” Filippelli said. “This is, unfortunately, the perfect weather to make potholes on roads. The temperature doesn’t stay stable enough to be able to fix them with a proper kind of pothole mix.”

It’s because of these and other concerns that the Indianapolis Office of Sustainability is holding seven climate-focused workshops — called the Thriving Neighbors Series — at city parks to teach residents about what changes are coming and how to adapt to them.

Filippelli is leading the first workshop, Climate Change 101, on Tuesday, April 9 at the Rhodius Park Family Center on the west side.

“I try to relay the fact that climate change is here and it’s going to continue until we get smarter about reducing carbon emissions,” he said. “We have a lot of ways to mitigate climate change and adapt to it.”

If you’ve gone walking in the woods out West lately, you might have encountered a pile of sticks. Or perhaps hundreds of them, heaped as high as your head and strewn about the forest like Viking funeral pyres awaiting a flame.

These slash piles are an increasingly common sight in the American West, as land managers work to thin out unnaturally dense sections of forests — the result of a commitment to fire suppression that has inadvertently increased the risk of devastating megafires.

“We have an epidemic of trees in Colorado,” said Stefan Reinold, a forester with Boulder County’s Parks and Open Space department. In the Rocky Mountain forests that he manages, a century of stamping out wildfires as soon as they arose failed to account for the role fire plays in maintaining healthy forest ecosystems. Today, the resulting abundance of densely packed pines and firs fuels huge blazes.

In response, the federal government has committed nearly $5 billion in the Inflation Reduction Act and Bipartisan Infrastructure Law to thinning forests on about 50 million Western acres over the next 10 years. Although this can be accomplished with prescribed burns, the risk of controlled fires getting out of hand has foresters embracing another solution: selectively sawing trees, then stripping the limbs from their trunks and collecting the debris.

The challenge now is what to do with all those piles of sticks, which create fire hazards of their own. Some environmental scientists believe they have an answer: mushrooms. Fungus has an uncommon knack for transformation. Give it garbage, plastic, even corpses, and it will convert them all into something else — for instance, nutrient-rich soil.

Down where the Rocky Mountains meet the plains, in pockets of forest west of Denver, mycologists like Zach Hedstrom are harnessing this unique trait to transform fire fuel into a valuable asset for local agriculture.

For Hedstrom, the idea sprung from an experiment on a local organic vegetable farm. He and the farm owner had introduced a native oyster mushroom to wood chips from a tree that fell in a windstorm. “That experiment showed us that the native fungi were helping to accelerate the decomposition really substantially,” he said. Working with local governments, environmental coalitions, and farmers, he is now honing the method.

As part of its regional strategy, the U.S. Forest Service plans to thin more than 47 square miles — an area larger than Disney World — along Colorado’s Front Range. Hundreds of thousands of slash piles already lay in wait here until conditions are right for burning. Ideally, this means snow on the ground, moisture in the air, and little wind. It can be a hard recipe to come by.

When slash piles are set alight, they burn longer and hotter than most wildfires over a concentrated area. This leaves behind blistered soil where native vegetation struggles for decades to take root. As an alternative, foresters have tried chipping trees on-site and broadcasting the mulch across the forest floor, where it degrades at a snail’s pace in the arid climate. Boulder County also carts some of its slash to biomass heating systems at two public buildings. “We’re removing a ton of wood out of forests for fire mitigation,” Hedstrom said. “This is not a super sustainable way of managing it.”

He hopes to show that fungi can do it better.

Jeffrey Ravage is a forester with the Coalition for the Upper South Platte, which manages protection and restoration of a more-than-million-acre watershed in the mountains southwest of Denver. He describes the action of saprophytes, a type of fungi that feeds off dead organic matter, as “cold fire.”

Like a flame, saprophytic fungi break organic material into carbon compounds. Mycelium, the often unseen, root-like structure of the fungi, secretes digestive enzymes that release nutrients from the substrate it consumes. Whereas a flame destroys nearly all organic nitrogen, mycelium can fortify nitrogen where it’s needed in the forest floor.

“We do hundreds to thousands of acres of fire mitigation a year,” Ravage said.

Standard thinning costs somewhere around $3,000 per acre, about a third of which is spent hauling out or burning the slash. Using mycelium could drastically reduce that cost. With the right kind of fungi, Ravage said, “we can do in five years what nature could take 50 years to a century to do: create organic soil.”

Though the method is new, it’s not untried. At the Balcones Canyonlands Preserve, north of Austin, Texas, biologist Lisa O’Donnell deploys mycelium to combat invasive glossy privet that spills over from surrounding urban sprawl. After the intrusive trees are cut and piled, volunteers inoculate — or seed — them with native turkey tail fungi, which take about three years to transform hard logs into crumbly sponges.

Eventually, the woody material breaks down into a rich and water-retentive loam that O’Donnell uses to rebuild the Balcones’ deteriorated soils. “You don’t have to burn it or haul it out. You’re using that biomass, keeping it in place and recycling it,” she said. “You’re turning a negative into a positive.”

For mycelium to be a truly viable solution to wildfires, however, it would have to work at the scale of the Western landscape. Hedstrom is experimenting with brewing mycelium into a liquid that can be sprayed across hundreds of acres. “It’s a novel biotech solution that has great promise but is in the early stages,” he said.

Ravage doubts it could be so easy. “Half the battle is how you target the slash,” he said. Success stories like the Balcones are rare. Ravage has spent a decade cultivating wild saprophytes and perfecting methods of applying them in Colorado’s forests.

He begins by mulching slash to give his fungi a head start. Then he seeds the mulch with spawn, or spores that have already begun growing on blocks of the same material, and wets them down. Fungi require damp conditions and will survive in the mulch if it is piled deeply enough. Given the changing character of Western forests, however, aridity poses a serious hurdle.

At his lab in the Rockies, Ravage grows about a ton of spawn annually. To meet the demands of forest-fire mitigation, he wants to produce 12 tons every week. This presents an opportunity for intrepid mushroom farmers, should the government choose to fund them, but it’s not the only way agriculture could benefit. “There’s going to be a lot of wood chip waste continuously coming out of the forest,” said Andy Breiter, a rancher in Boulder County. “We can use those resources.”

Some Front Range farmers pay to truck in compost from Vermont. Instead of adding synthetic fertilizers or importing compost, Breiter is using Hedstrom’s mycelium to turn forest slash into organic soil that he can work into his degraded land. “I’m trying to increase the productivity of my land while recognizing that past systems of productivity created these problems to begin with,” Breiter said.

Bills addressing climate change are some of the biggest casualties of Connecticut's legislative session.

One in particular is House Bill 5004, an all-inclusive bill designed to implement reforms keeping the state climate goals on track. The bill failed in the Senate, due to Democrats not giving enough time to consider it and Republican threats to filibuster it.

Samantha Dynowski, state director of the Connecticut chapter of the Sierra Club, said climate action is not moving in the right direction.

"They clawed back the climate legislation they passed three years ago by not passing the clean transportation regs that were presented to the Legislature in late 2023," Dynowski pointed out. "Not only are we not making progress forward, we're actually taking steps backward."

While the bill had wide support, some felt it encroached on their freedoms and limited energy supply competition. Dynowski argued climate legislation's need is only growing beyond climate impacts. A recent report shows greenhouse gas emissions grew in 2021, a trend set to continue without legislative action.

While some bills failed in committee, others did not pass a vote in one of the General Assembly's chambers. Dynowski contended climate action was not as much of a priority for lawmakers as it should have been but she acknowledged there was movement on some issues.

"There was in the bonding package, $25 million for heat pump deployment, so that will be helpful," Dynowski emphasized. "And in the ARPA funding package, a program for school solar and a requirement that all school districts will assess schools for solar."

A state watchdog report said one priority should be boosting electric vehicle use. It has not been easy since misinformation made some lawmakers reluctant to pass cleaner emission standards.

Proposed standards last year required 90% cleaner emissions from internal combustion engines and that carmakers deliver 100% zero-emission vehicles by 2035.

Moms from a nonpartisan climate science group are gearing up for summer, getting the word out to Pennsylvania families on how more frequent and extreme weather events can affect children.

Last year, the U.S. experienced 28 separate weather and climate disasters, including a wildfire in Hawaii, tornado outbreaks and major flooding events.

Tracey Holloway, professor of energy analysis and policy at the University of Wisconsin Madison and a member of the group "Science Moms," pointed out mothers are often the decision makers for their household purchases, so doing some research can make a difference.

"Climate change is a real issue and there are real solutions," Holloway pointed out. "When we're making big purchases, to be thinking about whether this is a purchase that's going to move things forward in the right way; whether it's an electric vehicle, rather than one that uses a lot of gasoline, or an energy-efficient dishwasher."

According to a Climate Change Impacts Assessment from the Pennsylvania Department of Environmental Protection, rainfall in the state is expected to increase by an average of 8% annually, with winter and spring seeing the most significant surges.

Holloway added it is important to move toward cleaner energy quickly, as it will help families to be healthier in the long run.

"Almost anything we do to reduce carbon emissions also reduces emissions of a lot of other chemicals in the air," Holloway noted. "These include nitrogen oxides and particulate matter, and cancer-causing chemicals. So, there are immediate health benefits from moving to clean energy."

She added many climate solutions lie not with individuals, but with corporations producing energy and manufacturing vehicles, as well as with the elected officials who shape policies. She encouraged moms in Pennsylvania to share information, speak up and work with lawmakers on solutions for climate change.
