 Hello, I'm Jonathan Froome with BBC Climate Watch. This week we meet the Kenyan 29-year-old Jasper Machogu. He's a farmer, and on social media he's become known for denying the existence of climate change. To his thousands of followers, he presents himself as a campaigner, a flag-bearer for fossil fuels, and he certainly appears to have struck a chord with some in the West who, like him, reject the overwhelming scientific consensus on climate change. But is there more to his campaigning than meets the eye?
