Planning for climate change is not some frivolous waste of time, a waste of money. It is essential to our troops and to their wellbeing, and the national security of this country.

This is so unpredictable. And we've never seen anything quite like this in our lifetime, so there is no playbook here.

This is really authoritarian.
