Is there any chance to skip the known_hosts check without clearing known_hosts or disable it in ssh.conf? I neither have access to known_hosts nor ssh.conf yet.
Don't find any suitable in man.

scp is supposed to take the same command line options as ssh, try:
-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null
Maybe add -q to disable the warnings as well.
For those of us who are less versed in Linux shorthand, the full syntax would look something like this:
scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -r $source $user@$host:$destination
known_hostsfile is created once you have connected, so all should be fine.
