ikki Held grew up on her family’s ranch in Montana, watching the land transform amid the climate crisis. The Powder River, which runs through the property, has sometimes dried up during drought, leaving crops and livestock without water. At other points, rapid snowmelt and heavy rains have caused flooding and eroded riverbanks, making the land difficult to use.

Two years ago, the 24-year-old and a group of other young people won a groundbreaking legal victory, intended to prevent those impacts from worsening. In August 2023, a judge ruled in favour of plaintiffs in Held v Montana, in which 16 young people accused the state of violating their constitutional rights by promoting planet-warming fossil fuels. The state’s supreme court affirmed the judge’s findings late last year, but plaintiffs say lawmakers have since passed new laws that violate that ruling. So last week, they filed a new petition calling on the supreme court to enforce their earlier win, one of several youth-led constitutional climate lawsuits filed in the US this year.
