Think critically

Given the substantial model diversities, how can designers make informed decisions about material selection or system design when facing such uncertainty in environmental predictions?

Design Principles

"Design for uncertainty: Incorporate robustness and adaptability into designs to accommodate a range of environmental conditions, particularly those influenced by complex atmospheric processes with high model diversity."

Understanding these model diversities is crucial for accurate climate modeling and environmental impact assessments. Designers and engineers working on air quality, climate technologies, or materials exposed to atmospheric conditions must acknowledge the inherent uncertainties in current predictive models.

What This Means for Your Design

Different computer programs that simulate how tiny particles in the air (aerosols) behave give very different results, which makes it hard to be sure about how they affect the climate or air quality.
