A Key Paris Agreement Goal Is Dead. What Now?

What the report says

At the COP31 United Nations climate summit in Antalya, Turkey, negotiators are grappling with the collapse of the Paris Agreement’s best-known target: limiting global warming to 1.5 degrees Celsius above preindustrial levels. The New York Times reports that many scientists now believe the world is likely headed for far more warming unless emissions fall sharply, and that diplomats are confronting what comes after a goal that once anchored climate talks.

According to the article, officials and climate advocates at the summit largely rejected replacing 1.5 with a new benchmark such as 2 degrees or 2.5 degrees, arguing that endlessly revising targets could weaken ambition. Instead, some leaders said the focus should remain on keeping overshoot as small and brief as possible, while still treating 1.5 as the formal Paris goal. Chris Bowen, Australia’s climate minister and a lead negotiator, said the world has no chance of staying at 1.5 degrees. Ilana Seid of Palau and other representatives warned against abandoning the target altogether.

The piece adds that scientists and advocates are increasingly discussing how to reduce carbon dioxide already in the atmosphere, including large-scale carbon capture and other geoengineering ideas, though these remain controversial and difficult to deploy. The broader context is that emissions remain near record levels even as clean energy expands, making a return to 1.5 degrees highly challenging.
