The Archbishop of York John Sentamu has praised Samoa's switch to renewable energy during his visit which also saw him honoured with a chiefly title.
Dr Sentamu is raising awareness about climate change and global warming in his first visit to the country.
He says it's obvious it's happening and there's no need for more science on the issue.
"Somebody many, many miles away is creating the difficulties affecting you. How do we actually stop other people fouling your home? So we need leaders that are actually going to be capable of doing this."
