Berliner Tageszeitung - Verdict awaited in historic US climate trial

Held v. Montana, which concluded Tuesday, has been closely watched as it could bolster similar litigation that has been filed across the country.

It is the first case involving a constitutional claim against a state, and also represents a rare instance in which climate experts have been questioned on the witness stand.

Judge Kathy Seeley, who oversaw the trial in the state capital Helena, instructed lawyers for both sides to file post-trial written submissions within two weeks, after which she would render her verdict.

She has the power to declare as unconstitutional a state law preventing agencies from considering the impacts of greenhouse gasses when issuing permits for fossil fuel development.

Earlier, a large group of supporters waved placards and cheered the plaintiffs and their lawyers as they entered the courthouse, according to footage seen on social media.

At the heart of the case is a provision within the fossil fuel friendly state's constitution that says: "The state and each person shall maintain and improve a clean and healthful environment in Montana for present and future generations."

The youths, ranging in age from five up to 22, have said they have been harmed by the "dangerous impacts of fossil fuels and the climate crisis," with children "uniquely vulnerable" to its worsening impacts.

During his closing arguments, the plaintiffs' lawyer Nate Bellinger, of the nonprofit Our Children's Trust, said his clients "did not ask for money, but they asked only that their government embrace its constitutional responsibility to alleviate the harms of its own conduct."

While Montana argues climate change is a global issue, the plaintiffs "localized this harm in their backyards of felled, diseased trees; the melting of Montana's majestic glaciers; ...skies that are full of choking smoke, and rivers that run dry."

"The plaintiffs acknowledge that the work to stop and reverse climate change will be a lifetime journey, but they are asking this court for help," he said.

Montana Assistant Attorney General Michael Russell on the other hand argued that the matter of energy policy should be decided by the people, through their representatives in the legislature.

"This case has received national attention in part because it has been billed or at least perceived as a sort of referendum on climate change. This is not supposed to be a town hall meeting or a popularity contest, it's a court of law," he added.

Russell said that while the state accepted that man-made emissions were responsible for warming, expert witnesses for the prosecution had not been able to quantify the extent to which Montana's laws were responsible for impacts on the ground.

- 'Compelling stories' -

The trial began on June 12 and concluded a few days earlier than expected after Montana declined to call to the stand several experts, including its only climate scientist, Judith Curry.

Curry has contested the scientific consensus on climate change, declaring for example "there's no emergency."

Over the course of proceedings, the court heard direct and emotional testimony from the plaintiffs about specific ways their health, emotional wellbeing, family finances and cultural traditions had been impacted.

Lead plaintiff Rikki Held, 22, whose family runs a ranch in Montana, said that their livelihoods and wellbeing had been increasingly impacted by wildfires, extreme temperatures and drought.

Claire Vlases, 20, said: "When I think about summer, I think about smoke. It sounds like a dystopian movie, but it's real life."

Lawyers for the plaintiffs also called renowned climate, health and psychiatry experts to testify.

These included eminent climatologist Steve Running, who was part of the UN body that won a Nobel prize in 2007.

Michael Gerrard, who founded the Sabin Center for Climate Change Law at Columbia University, told AFP the plaintiffs lawyers "did a wonderful job presenting and giving a human face to the case by having all these young people tell their own personal compelling stories."

Should the judge find in their favor, "we've seen in other cases that a favorable verdict in one jurisdiction can have a reverberating effect in many other places," said Gerrard. "It would be very energizing to young people and activists around the country."
