High Ambition Coalition Statement: Keep IPCC Science at the Heart of the Paris Agreement

As climate impacts intensify, deaths and damage rise, and we face the perilous prospect of a Super El Niňo, it is more important than ever that our fight against climate change is informed by the latest and best available science. We are extremely alarmed at the prospect of an overshoot of the 1.5°C temperature limit, and are committed to a response that strictly limits the magnitude and duration of any overshoot.

As the Intergovernmental Panel on Climate Change (IPCC) prepares to meet in Addis Ababa, we call on its members to safeguard the apolitical nature of the organisation’s work so it can continue to provide its timely authoritative assessments of the latest and best available peer-reviewed science to the UNFCCC through reports drawn up by experts and endorsed by governments from across the globe.

Divorcing the policy cycle under the United Nations from the scientific evidence provided by the IPCC would undermine the global effort to address the climate crisis and weaken international cooperation.

Access to the latest and best available science, including Indigenous Peoples’ knowledge and local knowledge systems, 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. Those most vulnerable to climate change rely on governments following the IPCC’s assessments to inform their policy decisions. 

As we look ahead to the next global stocktake under the Paris Agreement, timely information from all three working groups of the Seventh Assessment Report is critically needed to provide Parties with the most up-to-date information for their deliberations and decision-making. The upcoming IPCC Plenary session is the best opportunity to make this happen. We therefore urge all members there to support the scientifically robust, inclusive and policy-relevant timeline proposed by the IPCC Co-Chairs.

The latest and best available climate science is the ultimate tool we have to safeguard human lives, livelihoods, and our shared future. To protect that future and our communities, we must act now to preserve the strong link between the IPCC and the Paris Agreement’s global stocktake.
