Although climate scientists have repeatedly shown that global surface temperatures have increased in the last decades and that human-induced emissions of greenhouse gases are to blame, ex-US president Donald Trump has always made it quite clear that he does not believe global warming is human-related.

In 2012, he went as far as claiming that “climate change was a hoax invented by the Chinese to make the US manufacturing less competitive”.
