SANTE FE, N.M. - Partes de Nuevo México, incluyendo las cuencas de San Juan y Permian, se encuentran entre las áreas del país que están experimentando mayores niveles de contaminación de metano proveniente de la producción de gas y petróleo en tierra.

El metano es un potente gas de invernadero filtrado del “fracking” hidráulico y otras producciones de petróleo y gas. Y un nuevo reporte señala detalladamente "Quién es Quien" en la contaminación de metano en Nuevo México y a lo largo de los Estados Unidos.

De acuerdo al Centro para el Progreso Americano (Center for American Progress), once compañías emitieron en 2014 la mitad de la contaminación de metano proveniente de la producción de petróleo y gas en tierra, equivalente a más de 48 millones de toneladas métricas de dióxido de carbono.

Barbara Webber, directora ejecutiva de Health Action New Mexico, asegura que los efectos en la salud por emisiones de metano afectan más a unas poblaciones que a otras.

“Sabemos que nuestro estado tiene una tasa alta de asma, pero la población nativa americana presenta cuatro veces mayor índice de asma que cualquier otra etnia de Nuevo México. Por lo tanto, pensamos que ellos en especial llevan una carga pesada.”

El reporte analizó la Cuenca de San Juan en el área de Cuatro Esquinas y encontró que Conoco-Phillips está filtrando o venteando la mayor cantidad de contaminación de metano en la región, seguida por BP American y ExxonMobil. El documento muestra que en 2014 la industria del gas y el petróleo emitieron el equivalente a más de las 5 millones de toneladas de dióxido de carbono en el área.

Alison Cassady, directora de políticas de energía doméstica en el Centro para el Progreso Americano (Center for American Progress), dice que existen muchas compañías implementando mejores prácticas sólidas para reducir las emisiones de metano –pero la preocupación es por aquellas operaciones que no lo están haciendo.

“Es tecnología existente, está a la venta, y las empresas de todo el país la están usando. El metano es un contaminante global súper cargado que resulta mucho más potente que el dióxido de carbono, y por eso nos interesa tanto cortar la contaminación de metano que emana de la mayor fuente industrial: el sector petrolero y gasero.”

La Agencia de Protección Ambiental fijó recientemente los límites a las emisiones de metano de nuevas fuentes, y se le está pidiendo a la agencia que fije estándares para los pozos y equipo que se encuentran ya en operación.

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.
