PARK CITY, Utah -- As talks continue at the annual international climate summit, Utahns are among those urging the U.S. to follow up on its commitments. They want Congress to pass federal climate legislation and President Joe Biden to declare a national climate emergency.

Glenn Wright, chair of the Summit County Council and a Vietnam War veteran, is one of dozens of local elected officials concerned for both the immediate effects and the long-term consequences of climate change.

"I consider climate change an existential threat to the world," Wright asserted. "But it's really even more important to our environment here in the Summit County area."

The Biden administration's Build Back Better framework includes more than $500 billion in investments to curb climate change. Groups say the investments are urgent, but more will be needed to address the global consequences.

Wright is deeply concerned about the geopolitical issues caused by a warming planet, but said it also causes environmental problems in southwestern Utah.

"We have a really significant number of trees in the forest that are dying from beetle kill and are now emitting both carbon dioxide and methane and their deterioration," Wright pointed out. "They need to be removed, so we can get some new growth in there and revitalize."

Alex Cornell du Houx, former state representative and president of Elected Officials to Protect America and a veteran, said during his time in Afghanistan, he witnessed first-hand the impact that water and other resources can have during times of conflict.

"Conflicts across the world are due to climate and water-security issues," Cornell du Houx emphasized. "What's happening, unfortunately, is it's becoming a threat multiplier, that the U.S. is very insulated in many ways against, but it's also coming to the U.S. in much more grave manners."

World leaders concluded their speeches earlier this week and secured global agreements to reduce deforestation and methane emissions. Meanwhile in Congress, Democrats are trying to keep a measure in the Build Back Better Act that would place fees on methane emissions.

A technology that once existed only in science fiction soon could emerge as a viable solution to climate change. The city of Flagstaff has added carbon dioxide removal to its plan to reach carbon neutrality by 2030.

Flagstaff officials say once the technology is proved and deployed, it will extract and neutralize carbon and other pollutants from the atmosphere.

In recent years, significant progress has been made in developing systems that can remove greenhouse gases from the atmosphere.

Ramon Alatorre is climate and energy coordinator for the northern Arizona city. He said it could be one of the first in the country to implement a climate plan to capture and store carbon dioxide.

"We can do as much reducing as possible, but we're still going to be producing some emissions," said Alatorre. "And so there's going to, by necessity, be the other half of the equation. In order to be net zero, we're going to have to remove emissions from the atmosphere."

Alatorre said demonstration projects in Iceland and around the world show promise, but are not yet ready for commercial deployment.

He said his office also is working closely with the Center for Negative Carbon Emissions at Arizona State University to develop CDR technology.

Alatorre said Flagstaff is part of the Four Corners Coalition with other governments across the region - including Boulder County, Colorado - seeking to obtain the new technology when it becomes available.

"If we join with Boulder and half a dozen other communities," said Alatorre. "And suddenly we've got an aggregated demand and an aggregated pool of resources that really might attract somebody that wouldn't have looked at Flagstaff by ourselves."

Alatorre said while communities such as Flagstaff eventually will utilize a variety of solutions for removing greenhouse gases, he believes CDR will play a major role in cleaning the atmosphere.

He said while the technology may be expensive, the cost of not dealing with climate change could be much higher.

"Cost curve reduction could be achieved certainly by mid-century if we get started now," said Alatorre. "But that we need those early projects to get the ball rolling, that it's really going to be deployment-led innovation that result in cost coming down and scalability coming up."

The mayor of Huntington, where more than 200 homes were recently damaged by severe flooding, said now is the state's "one chance" to prevent other residents from experiencing the same tragedy.

Last week, leaders from across West Virginia gathered in Charleston to coordinate on a new state Flood Protection Plan. Huntington Mayor Steve Williams was there, and he later warned that flooding can wipe out everything people have worked for overnight.

"Right now, I have over 215 homes that have just been devastated," said Williams. "This is just ruining people's lives. They've lost everything. The effect on people's lives is not just palpable. It's real."

West Virginia Gov. Jim Justice toured Huntington's flood damage earlier this month, just two days after declaring a State of Emergency for Huntington and other areas affected by flooding.

Projections say the state's mountains mean West Virginians can expect to be some of the hardest hit by climate driven natural disasters. Mayor Williams said the only solution is for West Virginia to work together.

"Local, county and municipal governments, but you don't leave out the people in the neighborhoods," said Williams. "Everybody plays a role in this. We have one chance to get this right now. Whether you believe in climate change or not, these things are happening more often than they've ever happened."

Robert Martin is the director of West Virginia's resiliency office. He said they expect to have an update to the state's 18-year-old flood plan by the end of the year.

But Martin stressed that West Virginians have to realize flooding is going to happen here, and be ready to take the steps to mitigate that reality.

"The topography of the state is such that you're always going to have rains," said Martin. "Rains seem to be a little bit more frequent than they used to be, or they're cells of heavy rains that occur. But, we'll do what we can to mitigate those, so that we all get some flooding, we know that, but it'd be at a much lesser level."

Fifteen conservation groups from Wyoming and across the nation have filed administrative protests challenging the Biden administration's plans to resume oil and gas leasing on public lands as early as June.

They're calling for the president to end new leasing in order to protect communities, water and wildlife. Dan Ritzman - lands, water, and wildlife campaign director for the Sierra Club - said the move is critical for the administration to meet its own climate goals.

"One of the biggest single sources of greenhouse gases across the country is fossil-fuel leasing on our public lands," said Ritzman. "So to address climate change, we need to keep those fossil fuels in the ground, keep them from being burned."

Lease sales set for June include 144,000 acres across eight western states, with a majority of acres in Wyoming. Oil companies repeatedly have claimed that opening up more public lands for drilling can ease pressure on international supplies and lower gas prices.

The protests call for a halt to oil and gas leasing, and a nationwide plan to align federal fossil-fuel management with the goal of avoiding the most catastrophic impacts of climate change.

Ritzman said new leases on public lands won't lower prices at the pump, in part because it takes years for oil companies to develop leases. He added that companies already have plenty of options for drilling.

"The oil and gas industry is currently sitting on millions of acres that they have yet to develop," said Ritzman. "They are making those claims not to help the general public with gas prices but to get their hands on more of these public lands."

The new leases come on the heels of record industry profits. Shell Oil brought in more than $9 billion in profits in the first quarter of 2022, according to a Guardian report - nearly triple its profits during the same period last year.

Ritzman said lands owned by all Americans have been monopolized by the oil and gas industry for far too long. He said it's time for public lands to be part of the climate solution, not the problem.
