Summary

Story summary

Brief climate events such as El Niño or volcanic eruptions provide limited insight into equilibrium climate sensitivity due to delayed climate feedbacks.
The past decade shows accelerated global warming, diverging from linear trends around 2015.
This divergence challenges climate models, particularly those with low climate sensitivity.
In the coming years, understanding climate sensitivity may improve as feedbacks respond slowly to temperature changes, as shown by the Pinatubo eruption's limited cooling effects.
