Smaller or marginal wells account for just 6% of the nation's oil and gas production, but are responsible for half of all methane pollution in the U.S., according to a new report published in the journal Nature Communications.

More than 30,000 marginal wells across Colorado, Utah and Wyoming produce 200,000 tons of methane pollution each year.

Laurie Anderson, Colorado field organizer for Moms Clean Air Force, said methane is a major driver of climate change because it is 80 times more potent than carbon dioxide at trapping heat in the atmosphere.

"Here in Colorado we're seeing increased drought and heat resulting in increased wildfires that threaten our communities, even in the middle of winter," Anderson observed. "Reigning in methane pollution is critical for keeping our planet habitable for our children and grandchildren."

She added it is also a public health issue. Colorado's air quality was recently downgraded from serious to severe by the Environmental Protection Agency (EPA), for ground-level ozone levels far above limits set under the Clean Air Act.

Oil and gas emissions are a major contributor to ozone, especially along the Front Range, which put vulnerable communities, including small children and older adults, at risk.

Industry groups have argued inspections and equipment upgrades needed to prevent waste are too costly for smaller operators.

Jon Goldstein, senior director of regulatory and legislative affairs for the Environmental Defense Fund, countered smaller wells usually are not owned by mom-and-pop operations.

"The vast majority of these wells belong to large, often multinational oil and gas companies that have more than enough capital to invest in these wells," Goldstein argued. "It's just a matter of making sure, through regulations, that they do so."

The study found smaller wells lose enough methane, the primary component of natural gas, to meet the energy needs of more than 3.6 million U.S. homes annually. Colorado recently adopted rules to tackle methane emissions including marginal well sites, and Anderson said the EPA should follow suit.

"Colorado is making great progress on limiting methane pollution, and we need the EPA to follow Colorado's lead," Anderson urged. "By ensuring regular monitoring at all smaller high-polluting and leak-prone wells and upgrading equipment to eliminate leaks."

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.

Wet weather this spring has improved drought conditions in Minnesota and southern Canada. However, experts remain on alert for increased wildfire activity and other climate changes affecting people's health.

Poor air quality was a frequent topic last year in the upper Midwest, as smoke pushed down from Canadian wildfires. Researchers said climate change is fueling hotter and drier summers, making forests more susceptible to large fires.

Dr. Bruce Snyder, co-founder of Health Professionals for a Healthy Climate, worries about a repeat summer of thick, hazy smoke in the air creating unhealthy conditions.

"When that happens, people have more respiratory disease; people who have chronic lung disease tend to get sicker," Snyder explained. "There's a lot of downstream consequences for people all over the world, but certainly here in Minnesota."

Snyder noted the transition to cleaner energy sources is complex, but acknowledged pollution events place more emphasis on the need for less reliance on fossil fuels, due to their contributions to a warming planet. The Minnesota Pollution Control Agency said the state has had 46 air quality alerts since 2015, and 34 of those were because of wildfire smoke.

Snyder emphasized it is not just air pollution from wildfire smoke to worry about. He pointed out there are other ways a person's health can suffer from climate change.

"We've got many more dangerous insects -- ticks, mosquitoes, and so forth," Snyder stressed. "This is having a profound effect on our wildlife. But also, we're seeing a lot more progressively rising rates of Lyme disease, of West Nile virus."

Year-over-year statistics may vary, but state health officials say the median number of Lyme disease cases has risen in the past decade. Snyder added adverse health effects of climate change can be much harder for populations lacking stable housing.
