Climate prediction denial can be defeated by global coordination.

• Donald Trump fired several hundred employees of the U.S. National Oceanic and Atmospheric Administration (NOAA), triggering discussions about the impact on critical weather and climate services.

• The NOAA was under considerable pressure during Trump’s first term as U.S. President, which led to the downsizing of the organization.

• Climate predictions focus on meteorological changes that occur more slowly across multiple seasons, offering various possible scenarios for multiple decades to come.

• Climate predictions are national efforts with some coordination under the UN World Meteorological Organisation (WMO), especially for global observational systems.

• A globally coordinated climate predictions system will bring about higher-resolution models and more accurate predictions for all countries, helping governments respond better to the rapidly emerging suite of extreme events.

• Coordinated predictions will benefit from regular global stocktakes that record the numbers of events that were correctly predicted and how many provided meaningful inputs to governments to prepare for, mitigate, manage, and recover from climate-related disasters.

• There is a call to move beyond the current suite of coarse resolution models used for predictions and projections, to move towards the use of 1-km scale, or K-scale, models.

• Modellers should focus less on projecting the climate until the year 2100 and more on that at the more socially relevant timescales of multiple years to a decade or two.

• A cost-benefit analysis that justifies the existence of any sector that depends on government funding or market forces is crucial to build resilience in any sector that depends on government funding or market forces.

• Each center has to be prepared to defend itself with convincing answers to the difficult questions
