DENVER - During a summer filled with bad-air-quality-alert days across Colorado, children, people with respiratory illnesses and older residents have been forced to spend more time indoors.

Wildfire smoke and ground-level ozone created by exhaust and searing temperatures have been the culprits. Dr. Sheela Mahnke - pediatrician at EveryChild Pediatrics - said climate change already is impacting the children she sees, especially kids with asthma.

"Kids are particularly vulnerable to the impacts of climate change as well as air pollution," said Mahnke, "just because of their body size, the amount of air they breathe per minute, and their developing bodies, lungs, brains."

Communities of color and low-income households are disproportionately impacted by indoor and outdoor air pollution and its negative health outcomes. To reduce pollution inside homes, experts say avoid anything that burns, including candles, fireplaces and gas stoves.

Researchers at the University of California, Los Angeles found that one hour of cooking on a gas stove produces nitrogen dioxide at levels that would be illegal if found outdoors.

Families that can't afford electric appliances are advised to use back burners, and keep the vent running while cooking.

Natural gas burned inside homes also sends methane, a powerful heat-trapping gas, into the atmosphere.

Barbara Gottlieb - the environment and health program director for Physicians for Social Responsibility - said lawmakers and industry need to find a way to equip homes and workplaces to run on electricity produced from clean sources, and stop burning natural gas.

"Its power in terms of trapping heat in the atmosphere is more than 80 times that of carbon dioxide over a short time frame," said Gottlieb. "So for the sake of climate, you want to reduce your use of methane every way that you can."

The latest report by the world's top climate scientists confirms that less than a decade remains to dramatically cut greenhouse-gas emissions and avoid potentially catastrophic impacts.

Mahnke said she believes the time to act on climate is now.

"We're not waiting to see the impacts of climate change any more," said Mahnke. "We're really seeing the impacts now. And we need to act in a way that we can make a more green and equitable world for our children."

Results of a new study from Michigan State University suggest farmers no longer have to choose between growing crops and harnessing solar power. They can do both on the same land.

The 25-year study of California farmland found farmers who added solar panels, a practice known as agrivoltaics, made more money per acre than those who did not. The research shows crops and solar work together, especially when panels are placed on low-yield acres, or spots not growing as much food due to poor soil or too much shade.

The research indicates the approach helps farmers boost income without reducing food production.

Jake Stid, a graduate student at Michigan State and lead author of the study, said farmers can also benefit through a system called Net Energy Metering.

"A return structure where farmers can directly in many cases, interconnect so they can use the electricity to offset their own needs, as well as sell excess generation, excess electricity back to the utility for a discounted rate," Stid outlined.

Researchers estimate California land now used for solar panels could have fed 86,000 people had it stayed in crops. The study looked at the trade-off between farming and solar energy, while critics warned it could worsen food security by reducing farmland.

Stid highlighted his team chose California's Central Valley as the focus of the research due to its significant contribution to both national and global food production, particularly for a variety of orchard crops.

"It's a really, really agriculturally valuable state and it also happens to be a pretty water-stressed state," Stid pointed out. "Specifically, the Central Valley has been experiencing pretty significant drought, as well as over allocation of water resources."

Some farmers expressed concern about solar panels shading crops, affecting growth and reducing yields. Stid hopes to expand his research on solar arrays and food production nationwide, contributing to the ongoing debate among farmers on how to use land sustainably, without harming food production.

Lawmakers and climate change activists are speaking out against a rumored executive action by President Donald Trump to revoke tax-exempt statuses from climate nonprofits. One rumored change includes the removal of climate change from qualifying topics for the exemption.

Last Thursday in the Oval Office, Trump hinted environmental nonprofits could have their tax-exempt statuses scrutinized by the administration. Federal law currently bars a president from directly or indirectly ordering the Internal Revenue Service to investigate specific tax-exempt organizations.

Ruth Ann Norton, president and CEO of the nonpartisan Green and Healthy Homes Initiative, said she found the rumored executive actions troubling.

"We should not be talking about removing tax-exempt status from the civic good that comes from the work of nonprofits to prevent environmental issues that impair and impact and are harmful on people's lives," Norton contended.

Climate nonprofits are not the only organizations in Trump's crosshairs. He has suggested Harvard University should lose its tax-exempt status over defying demands from the administration dealing with diversity, admissions processes and antisemitism.

Tax-exempt status allows organizations to receive tax-deductible charitable contributions and not pay federal income tax.

Joelle Novey, director of the nonprofit Interfaith Power and Light in Maryland, the District of Columbia and Northern Virginia, said the actions may target climate nonprofits first but all nonprofits are at risk.

"There is no attack on civil society groups in the United States that isn't an attack on every one of us who expresses who we are by forming, supporting, volunteering and taking action through nonprofit organizations," Novey argued.

A federal judge last week ordered the Trump administration to unfreeze billions of dollars in climate and infrastructure funds previously targeted in an executive order on Trump's first day in office.

As of today, Earth Day, more than 50 elected officials have signed a letter urging lawmakers to make oil and gas companies bear the cost of climate change.

The California Polluters Pay Superfund, which goes before the state Senate Judiciary Committee today, would assess a fee on large oil and gas companies to pay for programs that mitigate damage from climate change.

Ahmad Zahra, a council member in Fullerton, signed onto the letter sponsored by the group Elected Officials to Protect America.

"Throughout the years, these large oil companies were really not necessarily telling the truth about air pollution," Zahra pointed out. "Just like we've seen in oil spills and ground pollution, the responsible party has to pay for it."

The Western States Petroleum Association opposes the bill, saying it would lead to higher gas prices. The bill directs the California Environmental Protection Agency to determine how much climate change has cost the state from 1990 to 2024. Federal data show California has suffered 46 natural disasters linked to climate change since 1980, each resulting in more than $1 billion in losses, with $250 billion from the Los Angeles firestorm alone.

Marisol Rubio, a council member in San Ramon, said 40% of the funds would be directed to low-income communities most affected by fossil fuel pollution.

"Those funds can then be used to better manage and correct and abate the pollution that not only already exists but that will come inevitably in the future, until we are able to be independent of fossil fuels," Rubio explained.

Advocates said right now, everyday Californians foot the bill for climate change in the form of higher taxes, insurance rates and utility bills, as well as via medical expenses for pollution-related illness.
