Trump lashed out at the world on climate change and immigration while addressing the UN's General Assembly. 

With a MAGA style rally speech, Trump began by touting his own domestic achievements. 

He went on to say the United Nations doesn't come close to its tremendous potential.

Trump also claimed open border policies are a failed experiment and warned against the 'green scam'. 

US correspondent Jonathan Kearsley labelled the speech 'extraordinary' and raised concerns over what this could mean for the US' relationship with allies.
