Trump calls climate science a ‘con job’. That could make tackling the crisis a whole lot easier | Francesco Grillo

Europe and Brazil have a rare opportunity, unimpeded by the US, to make a success of Cop30 - and reshape the world order

The climate crisis, Donald Trump told the UN last month, is the greatest con job ever perpetrated on the world". With these words the US president rejected the international scientific consensus and evidence that we can all check daily with a basic thermometer. He has also announced he is withdrawing the US from the Paris climate agreement, signed in 2015 by 195 UN countries. The US joins an axis of deniers including Yemen, Iran and Libya, countries that signed the agreement but never ratified it.

Paradoxically, Trump's reversal provides an opportunity for others to advance the climate agenda: to sketch out the blueprint of a possible new world order without the US, even if Washington was the architect of the old one.
