Jeremy Clarkson now believes in climate change

Jeremy Clarkson has changed his mind on climate change.

The \'Grand Tour\' host has long been dismissive of the concept, suggesting that global warming "isn\'t even worthy of a shrug" but he has had a change of heart after filming an episode of his Amazon Prime show in Cambodia.

He and his fellow presenters - Richard Hammond and James May - were forced to wade through a lake while filming a boat race from Siem Reap to Vung Tau in Vietnam.

Jeremy told the Sunday Times newspaper: "It\'s the first time that we\'ve ever admitted to there being global warming. It was alarming, genuinely alarming.

"The irony is not lost on me. A man who hosted a car programme for 30 years, limited to 7mph by global warming."

The former \'Top Gear\' trio endured "two days of utter frustration" as the three of them had to be pulled through the river, which had been reduced to a "puddle".

However, the 59-year-old star still took a swipe at Swedish environmental campaigner Greta Thunberg, suggesting that she has no answers to the climate crisis.

He said: "But we don\'t blame mankind for it, we\'ll let Greta do that. \'Ooh, we\'re all going to die\'. Right, tremendous. Now go back to school. But I genuinely hope people are working on what on earth to do about it."

Jeremy has previously expressed anger towards Greta, labelling the teenager as a "spoilt brat".

He claimed: "How dare you sail to America on a carbon fibre yacht that you didn\'t build which cost £15 million, that you didn\'t earn, and which has a back-up diesel engine that you didn\'t mention. So how dare you stand there and lecture us, you spoilt brat."
