To counter climate denial, UN scientists must be 'clear' about human role: IPCC chief

This week, Jim Skea, IPCC chair, urged the UN climate body to tell the world in a `very clear way` that humans are heating the planet at a five-day meeting in a skyscraper outside Paris with more than 600 scientists ending Friday.
The IPCC's assessment cycle requires comprehensive reports every five to seven years, and Skea said returning warming to 1.5C needs major emissions cuts and carbon dioxide removal.
Scientists highlighted new areas of research and knowledge gaps, including whether limiting warming to 1.5C long term is possible, while approval sessions remain difficult after the 1995 summary-for-policymakers incident.
France voiced strong support for the IPCC this week, and Skea met President Emmanuel Macron; the head of state and three senior ministers gave scientists confidence and enthusiasm to progress.
With COP33 approaching, the drafting process will culminate in a report due in 2028 or 2029 amid France pushing for 2028 while Saudi Arabia and India favour 2029, and Jim Skea warned recently it is `almost inevitable` the world will cross 1.5C.
