Absolutely right on the bias, but the article did label the ClimateLiars as “prophets of doom”, a rather non-complimentary description.
Probably an editorial oversight for which there will be journalistic demotions at the Daily Mail.
It's hard to tell if those are the Pope's words, or the reporter's.
Since it's negative (against the Algorians), I would lean toward it being the Pope's words. Reporters have something in their union contract about saying bad things about the Algorians.
