The kids’ lawsuit over climate change is our best hope now.

After a week that sent advocates of a habitable Earth reeling, new hope has emerged that could make way for substantial climate action in the near term—even during a Trump administration: The children and young adults suing the federal government for their right to a stable climate can now proceed to trial, an unprecedented move in the American legal system.

The path was cleared by a federal district court judge in Oregon who wrote an opinion preliminarily finding that a stable climate is a fundamental constitutional right. In the groundbreaking decision, announced on Thursday, U.S. District Court Judge Ann Aiken ruled in favor of a group of 21 children and young adults in their suit against the federal government. In denying the government’s motion to dismiss, Aiken, based in Eugene, Oregon, opened a path for an eventual court-mandated, science-based plan to bring about sharp emissions reductions in the United States. The case, Juliana v. United States, will now go to trial starting sometime in 2017 and could prove to be a major civil rights suit, eventually finding its way to the U.S. Supreme Court.
