I'm a rock climber and I've gotten into enough tricky situations on the cliffs. So long as you can take action the fear is manageable. It's when there is seemingly no viable action to take that the bad fear sets in.
Thing is, the risks I take personally as a climber aren't as big as the risk were taking collectively as a civilization by not acting on climate change, even though the risks I take go well beyond what most people would accept if they understand what they were in for.
