ANECDOTE

Climate Modeling as World-Building

  • Kate Marvel uses climate models, which are like "toy planets", to simulate various scenarios, including volcanic eruptions.
  • She describes climate models as "world-building machines" that help understand Earth's systems.
INSIGHT

Climate Model Uncertainty

  • Climate models, while complex, don't always yield precise predictions due to uncertainties in human behavior and natural systems.
  • Equilibrium climate sensitivity, a key metric, has remained stubbornly wide despite modeling advancements.
