US President Donald Trump has been criticised by world leaders for his stance on climate change, ahead of the global COP30 summit, BBC reported.

President Trump, who is not attending the meeting in the Amazonian city of Belem, was called a liar by the leaders of Colombia and Chile for his rejection of climate science.

UK Prime Minister Sir Keir Starmer acknowledged the waning political support on climate change. He said it had been a unity issue internationally and in the UK but "today sadly that consensus is gone".

Over the next two weeks countries will try and negotiate a new deal on climate change, with a particular focus on channelling more money to forest protection, according to BBC.
