D1.1. KGSIR on improved characterisation and understanding of the ERF concept

Work Package: WP1

Deliverable number: D1.1

Deliverable title: KGSIR on improved characterisation and understanding of the ERF concept

Key messages:

• This KGSIR summarizes recent advances in our understanding of Effective Radiative Forcing (ERF), and methods to quantify ERF.
• ERF is better constrained by using key observations of changes to the climate system in recent advances.
• Uncertainties in ERF due to changes in CO2 and other climate forcers remain substantial.
• Knowledge gains have been achieved on comparing various climate drivers relative to CO2 changes.
• Next steps are to quantify causes of the diversity in ERF due to CO2 in climate models, and improve understanding of aerosol-cloud interactions and thereby their ERF.
