With the Inflation Reduction Act supporting the beginning of a transition to clean school buses, elected officials in Florida are calling for quicker action.

The Miami-Dade County Public School System has ordered 10 electric school buses, with delivery expected next summer.

While it's well known that electric school buses will reduce greenhouse-gas emissions, a less talked about issue is kids' and bus drivers' long-term exposure to diesel exhaust.

The National Institutes of Health says exposure to diesel exhaust particulates is reasonably anticipated to be a human carcinogen.

Research indicates the amount of fine particulates inside a school bus can be 5 to 10 times higher than the surrounding atmosphere, and it's worse when buses sit still at idle.

Former Mayor of Pinecrest and former Florida state Rep. Cindy Lerner - who is currently on the national leadership council of Elected Officials to Protect America - said the transition to electric buses has advocates excited.

"We are really very excited about it," said Lerner, "not only because of the reduction in the greenhouse-gas emissions, but the significant health hazards to lung development - and even to brain development - in children by sitting on the school bus twice a day 5 days a week."

A half-hour ride to and from school each day amounts to 180 hours over a school year.

Earlier this year, the Miami-Dade School District adopted a resolution to move the district to 100 percent clean energy by 2030. The funding for this first purchase of electric buses came out of Florida's portion of the Volkswagen diesel settlement.

While the district will again apply to the Environmental Protection Agency Clean School Bus award program next year, advocates are calling for state-level action.

Lerner pointed to states such as Connecticut that passed its own Clean Air Act this year and will transition all state vehicles to electric by 2030. She said advocates in Florida must appeal to the state to do more.

"That'll be our project over the next couple years," said Lerner, "to go forward to the state and ask them to take that kind of action to set standards and to invest in clean transportation for school children throughout the state of Florida."

The Miami-Dade County Public School system is 4th largest in the nation, and with that comes a large fleet of buses. The district's buses currently log 13 million miles per year.

Luisa Santos represents District 9 on the Miami Dade School Board and said electrifying a fleet of this size will have a large impact on air quality.

"Our goal, really, is that we are working to electrify all 999 buses in our fleet," said Santos. "That is a huge number, and so if we can get it right, our impact will be tremendous."

School buses are getting cleaner in Washington state after this year's legislative session.

Lawmakers in Olympia passed House Bill 1368, which will fund the purchase of zero emission school buses.

Rep. Tana Senn, D-Mercer Island, said the program is getting off the ground quickly.

"As we work towards that long-term goal of all new school buses being zero emission, we're kick-starting this year with $40 million in grants to school districts in overburdened communities," Senn explained.

Going forward, Senn noted school districts will have to purchase zero-emission vehicles once the total cost of ownership is equal to or lower than the cost of diesel vehicles. The state is leveraging the state's Climate Commitment Act resources to fund the transition of its 10,000 school buses.

Devin Denney, director of transportation for Highline Public Schools in King County, which already has electric school buses in its fleet, said he has driven the electric buses and talked about some of their benefits from a driver's perspective.

"You're not competing against that engine noise, the kids aren't competing against the engine noise," Denney observed. "It's a much quieter bus all the way around. The major advantage, of course, is that there's no tailpipe emissions with an electric bus, so our kids' health is better protected."

Senn emphasized health studies have shown there are negative health effects from diesel vehicles for kids, and it is easy to understand why.

"If you think about kids waiting to get on their bus in front of an elementary school and you have this line of buses idling, letting out diesel fumes right at the height of a little child, it becomes obvious that this is probably not the most healthy thing for our children," Senn added.

Today, in honor of Earth Day, climate advocates are asking California lawmakers and Gov. Gavin Newsom to rally around a plan to put a $15 billion bond measure on the November ballot.

If passed, the bond measure would fund a range of climate resiliency measures.

Sam Hodder, president and CEO of the Save the Redwoods League, said March was the tenth month in a row to break monthly heat records.

"I think Earth Day is a terrific opportunity for the broader public to recognize how nature is critical for resilience, for our quality of life, for our mental and physical health, and for our communities more broadly," Hodder outlined.

Two similar bills to put a bond measure on the ballot are under consideration in Sacramento, Assembly Bill 1567 and Senate Bill 867, but they have been stalled since last summer. The bond would finance many programs, including some to restore wetlands that guard against sea-level rise, and to remove dead wood in forests to guard against mega-fires, which Hodder noted have killed 20% of the giant sequoias in recent years.

Opponents pointed out the state already faces a budget deficit and cannot afford to take on more debt. But only 5% of California's old-growth coastal redwoods remain, mostly due to aggressive logging many decades ago.

Hodder argued the giant trees can be critical ingredients in the fight against climate change because they trap so much carbon.

"Redwood forests sequester more carbon per acre than any other forest system in the world," Hodder emphasized. "We have the opportunity to transition the redwood forest from something that is vulnerable to climate change to something that is helping to solve and address the climate crisis."

Experts blame climate change for California's wild weather over the past few years, which has been marked by extreme drought, devastating fires and flooding rain.

A new report from the National Wildlife Federation warns that the effects of climate change in the Quad Cities, along the Iowa-Illinois border, will be severe.

But researchers got the public involved in studying to find ways to head off some of the most pressing concerns.

The report says climate change means a warmer, wetter future for the Quad Cities, which straddle the Mississippi River in Iowa and Illinois.

But rather than repeat what experts have already been saying about drastic flooding along the Big Muddy, Prairie Rivers Network River Health and Resiliency Organizer Nina Struss said researchers and Quad Cities residents brainstormed solutions to tackle the effects of climate change.

"Flooding and flash flooding were the top concerns," said Struss. "Extreme heat was also a big concern, as well as drought and other extreme weather events."

Researchers combined that information with hard science at the University of Illinois to create 3D models depicting what climate-induced flooding along the Mississippi could look like in the future.

The survey also asked people to identify which geographical areas and populations are most at risk from the effects of climate change, and worked with the community on solutions to mitigate some of them.

Struss said this research proposes what are known as nature-based solutions to combat the effects of climate change - restoring, preserving and even expanding existing ecosystems, like wetlands and tree canopies. But creating more eco-friendly infrastructure, too.

"Can we work to maybe have our pavements that we're putting in be more permeable, so that they can absorb that water and have that higher water-holding capacity?" said Struss. "Can we focus on areas to plant more native plants that have stronger root systems, versus ones that have shorter root systems, to help with that water-holding capacity?"

Struss said this research isn't a one-off. It will continue to change, she said, as the climate changes, the needs become more clear, and the effects more drastic.

She said progress in addressing climate change relies on more research, education and funding.
