Safety climate only refers to some elements of resilience.
Resilience means the capacity and capability to prevent, resist, manage the issue, and bouncing back after an event. Safety climate is rather prevent and manage the issue (surely not about bouncing back).
A steel concrete column is very strong and safe, but a huge impact can brake it. The wind, water and temperature changes slowly erode the concrete and the steel. The whipping willow has lower strength, but it is more resilient. The branches flexibly moving in the wind, water and cold cannot harm the tree. If a branch brakes, the willow grows more scions and replaces it fast. If the stem brakes, new willow trees would grow from the ground and cover the empty area.
