The Intergovernmental Panel on Climate Change is meeting this week in Addis Ababa, Ethiopia. Its members still disagree on when to publish its next big report, the Guardian and Reuters reported.

The report, known as AR7, sums up what is known about climate change. It was meant to be ready in 2028, before UN climate talks late that year. At those talks, governments will check how far they have come on the goals of the Paris deal, both outlets reported.

A group of countries including Saudi Arabia, Russia, India and China wants publication pushed back to 2029, both outlets reported. Reuters said the group, which also includes Kenya, wants the second and third parts of the report delayed.

They say more time would give scientists from poorer countries a bigger role. "If you have a process that goes very quickly … it wouldn't be inclusive," said Joyce Kimutai, who represents Kenya at the IPCC, Reuters reported.

Many poor and vulnerable countries strongly oppose a delay, the Guardian reported. More than 30 countries in the High Ambition Coalition called for the report to come out on time, both outlets reported.

"We cannot allow political interests to determine which science the world is willing to hear," said Jess Gasper, a minister for the Marshall Islands, the Guardian reported.

Some backers of the 2028 timeline say oil-producing nations are among the loudest voices for more time, Reuters reported. Russia's economy ministry called that framing a "deliberate misrepresentation," according to Reuters.

The IPCC does not do its own research. It reviews existing science, and every member government approves its reports, Reuters reported. Its last full review was published in three parts in 2021 and 2022, the Guardian reported.

The IPCC declined to comment to the Guardian.

What we know: IPCC members are meeting in Addis Ababa and remain split over delaying the AR7 report to 2029.
What we don't: Whether the meeting will end with an agreed publication date.
