WCRP plays a major role in supporting the development of new climate information systems. Global warming is “unequivocal” according to the Intergovernmental Panel on Climate Change (IPCC); some warming is guaranteed, and adaptation to climate change is essential. This requires information to assess vulnerability, devise coping strategies, determine possible impacts, and plan for future changes.

Climate observations and climate models are producing significant amounts of data and information. Research and development of Earth observing systems, models and field experiments comprise an intrinsic part of WCRP activities and contribute to the continuation and expansion of global environmental monitoring. Every WCRP project develops data and information and has a set of observation activities.

The WCRP Data Advisory Council (WDAC) acts as a single entry point for all WCRP data, information, and observation activities with its sister programmes, and coordinates their high-level aspects across WCRP, ensuring cooperation with main WCRP partners such as the Global Climate Observing System (GCOS) and other observing programmes.

WDAC works with the The WCRP Modelling Advisory Council (WMAC) to promote effective use of observations with models and to address issues related to the coordinated development of data assimilation, reanalysis, Observing System Sensitivity Experiments, and paleoclimatic data and their assessments.
