Indicator species and extremophiles

Things that exist in extremes if temperature or moisture are most vulnerable to climate change, and those with life cycles dependant on seasonal variation over decades at high risk. Creatures that hibernate bears and bats and frogs that can freeze, that then hop away, are better able to survive catastrophe. Evolution is the accumulation of changes over time, but while time passes. The times can change rapidly, depends on impact and force, plus geographic location.
