Australian Prime Minister Scott Morrison used his UN speech on Wednesday to slam critics of his country’s climate record and to suggest Swedish teen Greta Thunberg was being exploited by others for ulterior motives. Morrison, who snubbed a major UN climate summit two days earlier, also said the Great Barrier Reef was “vibrant and resilient”, weeks after his own government downgraded the world heritage site’s long-term outlook to “very poor” for the first time.
