When I look around, the biggest way in which we are failing to care for those in need is through ignoring climate change and acting like it doesn't exist. As a Christian, I believe that is something the church needs to know.
I don't think there are any churches that have "Thou shalt not believe in climate change" written in their actual statement of faith.
When I talk to my neighbor, or to someone at church who doesn't accept that the planet is changing, I know that they don't know any better. They've been told this information by somebody they trust and it's not their fault. They've just never heard otherwise.
