So you won't conceed that this is problematic that there is according to you presumably relevant data they could cite - even if it doesn't directly apply to yemen in that particular perioud, but they chose not to? I mean what ever happened to 'citation needed'.

I mean uncertainties is a bit of an umbrella term. You should be able to be certain about predictions if you make the error bars big enough. If you still can't come up with a reliable assertion doing this then things are spurious.
