Christmas can be tricky when family members hold conflicting world views, particularly on climate. But mostly we all want the same things - safety, peace, opportunity - we just see different ways of achieving them.
It can be helpful at Christmas to focus on what binds us, rather than what divides us.
And if an argument is brewing, perhaps keep the focus on what we're fighting for rather than what we're fighting about. Sometimes it turns out we're all on the same side.
