Session Description

Weather and climate data is essential for both finance ministries and the climate-science community to model the future, assess physical risks, and formulate climate strategies and policies. Yet serious data gaps exist, which severely affects the quality of weather and climate prediction globally and undermines the effectiveness of climate-related decision making. To address this long-standing problem, a new financing approach has been developed and a newly created financing mechanism will be presented at this event: the Systematic Observations Financing Facility (SOFF).

This session, co-hosted by the Coalition of Finance Ministers for Climate Action and the World Meteorological Organization, will bring the finance ministry and the climate-science communities together for the first time at a COP to discuss the urgency of closing the weather and climate data gaps and how Ministers of Finance can support this endeavor, as well as how climate data can be used by finance ministries to create more effective economic policies. 



In order for Finance Ministers to fully embed climate into their decision making, better data on climate risks and potential impacts are required. This has been continuously highlighted as part of the Coalition’s work under Helsinki Principle 4 on Mainstreaming Climate Change into Mitigation and Adaption policies, which addresses macro-fiscal and other relevant policy planning, budgeting, and disaster-risk planning.

Yet, according to World Meteorological Organization (WMO) Secretary-General Petteri Taalas, “today, less than 10% of required basic weather and climate observations are available from Small Island Developing States and Least Developed Countries”. While recent IPCC reports reveal the increasing global capacity in the understanding of climate change, it also highlights the persistent limitations for a number of countries where significant data gaps remain. 

To address this challenge, a breakfast meeting co-hosted by the Coalition and the WMO will be held to open COP Science Day on 10th November. This would likely be the first high-level meeting on climate change between Finance Ministers and leaders of the scientific community, and would reinforce the need for rigorous data and analysis to fully embed climate issues into fiscal and financial sector planning.

Coalition member countries would present current macroeconomic modelling and financial sector methodologies to the science community, stressing current gaps in data and knowhow and highlighting the challenges to be overcome. Representatives from the scientific community would document the severe data gaps that are limiting the understanding of climate change, showcase the latest tools and data which Finance Ministries might use to better inform their economic modeling and policymaking, and suggest how the Coalition could help close this gap.
