Indicators of Global Climate Change

The Indicators of Global Climate Change (IGCC) initiative is providing updates of several key global climate indicators reported by the Intergovernmental Panel on Climate Change (IPCC) that can help us to understand the state of the climate system and how it is changing.

The focus is on providing up-to-date estimates of policy-relevant global climate indicators that follow the causal chain from emissions to warming, including greenhouse gas emissions, human induced warming and the remaining global carbon budget.

In doing so, IGCC brings together timely information that can support effective climate decision-making in a findable, accessible, traceable and reproducible way.

The methodologies used to update the indicators are directly traceable back to the IPCC Sixth Assessment Report (AR6). The underpinning publication which describes these methodologies, and also provides further context and background.

IGCC is also working with the Climate Change Tracker to provide a reliable, user-friendly platform for tracking, visualising and understanding these indicators, aimed at policy-makers but open and accessible to all.
