## In brief

- Former US Secretary of State John Kerry said at COP31 in Antalya on Tuesday that the US would soon return to a leadership role in the global response to the climate crisis.
- A new report, as cited in the headline, found a surprise dip in fossil fuel emissions that it links to the Iran war launched by President Donald Trump.

## Why it matters

A possible US return to climate leadership could shape international negotiations and emissions policy, and the reported emissions dip gives researchers a new trend to examine, though its link to the Iran war needs checking against the underlying data.
