This presents a dilemma - we have fears for our children's future yet we so don't want them to be frightened. What can we say to reassure them while remaining authentic?
First of all, it's useful to understand that voicing our fears is not what makes our kids frightened, and pretending everything is ok does not make them feel safe.
Researchers have found that what most frightens young people is inaction - by governments, corporations, and communities. They don't see climate change as the problem, they see the failure to act as the problem.
So, when talking about climate change, it's helpful to listen to your child's perspective, ask what most concerns them, and validate it.
"Yes, the climate is changing, and yes, it's really bad."
"We all have reason to be fearful."
Take a moment to consider this, to be emotional about it, and to let it reveal what is most important to your child - their family and friends, people less fortunate, wildlife and nature.
This then gives you something to work with, to make whatever it is they value a little safer, better, protected.
You might then say,
"Ok, let's get to work. What are we going to do about it?"
