IPCC Deadlock: Global Policy TugofWar Over ClimateScience Reports

IPCC Deadlock on Climate Science Reports and Global Policy - The dispute reflects deep rifts between wealthy industrialized nations, major emerging economies and poorer nations over how to respond to rapidly warming temperatures and how much of that burden should be shouldered by different countries.

UN Environment Programme has said repeatedly that global efforts to limit warming are falling short and that faster emissions cuts are needed to avoid more extreme weather and climate-related disasters. Scientists have said climate change fueled wildfires that surged across Europe this summer and likely played a role in landslides and flash floods that killed hundreds in Nepal ​and China’s Tibet.

International Coalition Calls for Timely Science

“Access to the latest and best available science … enables a just, equitable, evidence-based approach to addressing the greatest challenge of our time, rather than one driven by those whose entrenched interests are at odds with reducing greenhouse gases,” the High Ambition Coalition said in a statement.  The statement, seen by Reuters, is signed by more than 30 countries, including European, Latin American and small-island states.

The Political Dimension: 'The Elephant in the Room'

The deadlock – unprecedented in the IPCC’s history – comes as the organization faces increasing pressure from governments critical of climate policies they say hurt industrial competitiveness or restrict the ability of emerging economies to use cheaper, more polluting fuels to meet development needs.

Proposed Timeline vs. Opposition to the Proposed Timeline

The IPCC will supposed to publish three key reports: one on the extent and causes of climate change, another on vulnerabilities and how countries can adapt, and a third on options to avoid warming getting worse.  Scientists chairing groups preparing the reports have proposed a work plan that would see all three approved by September 2028.  However, opponents of the chairs’ proposal want the second and third reports pushed into 2029, saying the timeline is too short to analyze thousands of studies, agree wording and complete expert and government reviews. The dispute is sowing discord and distrust in an organization intended to help countries bridge divides by providing a scientific basis for climate negotiations. Observers at five previous IPCC meetings described days of contentious debate. Participants have traded accusations of politicizing the IPCC’s work.
