Scientists preparing the next major United Nations climate assessments are setting aside both their most optimistic and most catastrophic warming scenarios, judging them no longer plausible. The shift reflects how modest progress in curbing emissions has narrowed the range of possible futures, even as the world looks set to overshoot the widely agreed warming limit. It is a sober reminder that humanity's efforts have changed the shape of the problem without yet solving it.

- The world's top climate scientists are discarding both their best-case and worst-case warming scenarios that have framed the debate for years.
- Modest gains in emissions reduction have pushed the feared catastrophic futures off the table, but the planet still appears headed past the agreed warming limit.
- Researchers are rebuilding the projections for the next series of major UN climate reports, reshaping how governments will read the risks ahead.
- The result is a narrower but less comforting picture: the danger has eased from the extreme, yet the threshold of concern still looks likely to be crossed.
Scientists preparing the next major United Nations climate assessments are setting aside both their most optimistic and most catastrophic warming scenarios, judging them no longer plausible.

Climate scientists are preparing the next wave of major United Nations reports, and in doing so they are letting go of two familiar markers: the most hopeful scenario and the most frightening one. For years, these extremes gave policymakers and the public a outer boundary for what the future might hold. Now researchers judge both to be unlikely.
The reason is encouraging in a measured way. Incremental progress in cutting emissions, through cleaner energy and shifting policies, has pulled the realistic range away from the catastrophic edge. Yet the new picture is not a relief. The world still appears likely to pass the warming limit that nations have set as a goal, which means the work of adaptation and deeper cuts remains urgent.
The revised projections will shape how governments and communities plan for the decades ahead. The story is still unfolding, and further reporting will add detail as the scientific process moves forward.

WASHINGTON (AP) — Scientists are jettisoning their worst and best case scenarios for a warming world as no longer plausible. That shows how modest gains in the fight to curb climate change have dialed back the most catastrophic of future h…
