New research from the University of New Hampshire could help dairy farmers increase profits while reducing their effect on the climate.

Scientists said adding a plant-based essential oil blend to cow feed can improve a cow's digestion and reduce the release of methane, a potent greenhouse gas.

Andre Brito, associate professor of dairy cattle nutrition and management at the University of New Hampshire, said the findings are especially true for pasture grazing cows and shows a happy cow makes for a healthier environment.

"If those animals are provided those conditions, they'll be more productive," Brito pointed out. "Then the amount of methane that's being emitted by those animals is diluted because they're producing more product."

Brito reported adding the plant oils led to a more than 6% increase in milk production, which is good news for the majority of New Hampshire dairies, especially small to mid-size operations with smaller profit margins and higher equipment costs.

Still, Brito noted the research findings could translate to larger, industrial-size dairies. The factory farms often hold thousands of cows, generating significant methane emissions through their hearty burps and manure, which is often stored in large, polluting lagoons.

Brito acknowledged although the plant-based oils are readily available for use, farmers must weigh the economic benefits and overall environmental impact.

"Any investment that the farmers would make in a product has to be tied to economics," Brito stressed. "Even though farmers overall, they are conscious about the environment and they want to make sure that there is less carbon, nitrogen footprint out of their farms."

Brito's research was conducted on cows as they transitioned from the winter indoor-feeding schedule to eating their favorite plants in the pasture, a diet change which can increase the cow's emissions.

Brito added he hopes the research can help farmers better understand when to add the oils to the cow feed to potentially reduce the cow's overall climate effect.

Insurance rates are rising quickly in California because of fires and floods linked to climate change and now, two new bills in Sacramento seek to make oil and gas companies pay.

The Affordable Insurance and Climate Recovery Act would create legal pathways for homeowners, insurance companies and the state insurance plan to sue and recover losses from oil and gas companies.

Melissa Romero, policy advocacy director for the nonprofit California Environmental Voters, said the companies misled lawmakers and the public.

"The one group that hasn't paid their fair share in all of this is oil and gas companies," Romero contended. "They knew since the '70s and the '80s that their products were creating runaway climate change. They hid the science, they did nothing about it, and they continued to push an agenda that stymied a lot of efforts to switch over to clean energy."

The Western States Petroleum Association called the bills a way for politicians to capitalize on tragedy. The California Independent Petroleum Association said the real culprits for the fires are arsonists, environmental lawsuits that prevent forest management, and cuts to firefighting budgets.

Romero also supports the Polluters Pay Superfund bill, which would charge fossil fuel companies according to their role in climate change and invest in climate-resilient communities.

"It requires the California Environmental Protection Agency to do a report about the actual costs, both looking backwards and forwards, that climate change has caused to California in terms of our infrastructure, disaster response and things like that," Romero outlined.

Proponents of the bills complained insurance ratepayers and taxpayers are hard hit by climate disasters. The state's FAIR Plan, the insurer of last resort, has assessed insurers and ratepayers $1 billion for Los Angeles wildfire claims so far. Meanwhile, State Farm is likely to get regulators' permission to raise homeowners' insurance rates by 22% after a hearing on April 8.

In the face of the severe effects of climate change across the country, new research offers a framework for how to measure Washington's climate resilience.

The research supports Washington's Climate Resilience Strategy, which was published last year.

Carlie Stowe, climate resilience specialist for the Climate Impacts Group at the University of Washington and the paper's lead author, said building resilience is critical in order to minimize effects from droughts, fires and other extreme weather events.

"As the government is investing in resilience, we want to make sure that we're spending that money wisely," Stowe urged. "And that the programs and activities we're investing in are resulting in increased resilience."

Stowe pointed out the research compares Washington's and South Carolina's approaches to climate preparedness to serve as a guide for other states. She added the research is one way to demonstrate Washington's leadership in this area, as taking such measurements is a new practice at the state level.

Stowe noted measuring climate resilience means incorporating data from dozens of sources, across communities, infrastructure, land and governance. It includes air quality levels, damage to infrastructure, and evacuations in extreme events like floods or wildfires.

She emphasized it was helpful to partner with South Carolina on this research, even though each state ended up with a different measurement framework.

"There's a lot more that we can learn together," Stowe stressed. "Continuing partnerships like this is really important for further building resilience across our country."

Stowe added the Washington State Department of Ecology will be implementing the plans and the public will start seeing initial results of the measurements in September.

Last year, filmmaker Michael Nash achieved the extraordinary when his documentary "Climate Refugees" was sent to the moon as part of a Lunar Museum project. Now, he's on a new mission: getting the faces of climate refugees featured on postage stamps to keep the conversation about climate migration alive.

"Climate Refugees," which premiered at Sundance and was later featured on Netflix, has been a powerful tool for raising awareness about the human impact of climate change. Nash and his team traveled to 48 countries, uncovering stories of forced migration driven by droughts, food shortages and environmental collapse.

"What we found was this intersection where overpopulation, overconsumption, lack of resources, and a changing climate were slamming into each other," Nash explained. "The outcome was forced migration: people running out of water and food in places they'd lived for hundreds, if not thousands, of years."

While the film's journey to the moon in 2024 was a historic milestone, Nash is now focused on a more down-to-earth goal: creating postage stamps featuring the faces of climate refugees, although gaining approval from the U.S. Postal Service's stamp committee will require demonstrating the issue's national relevance and historical significance.

Despite the progress in raising awareness, Nash emphasized the world has not done enough to address climate migration.

"There is not an international law accepted by all countries that gives asylum or protection to people forced to relocate due to climate change," Nash pointed out.

According to the United Nations, more than 20 million people
are displaced annually by climate-related events, making the need for action more pressing than ever.

Nash was a featured speaker at last week's Climate Correction Conference in Orlando. His next project, a film exploring the intersection of artificial intelligence and climate change, is currently in production and set for release in 2026.
