Jusper Machogu is a farmer from southwestern Kenya who describes himself as a “climate sceptic”: he wrongly claims that climate change is a “scam” or a “hoax” designed to hold Africa back. On social media, he has also become known as a staunch defender of fossil fuel exploration in Africa.

His views have caught the eye of those in the West who, like him, deny the overwhelming scientific consensus on global warming. They have helped him grow his following and spread his message globally. But, in doing so, has Mr Machogu unwittingly become a tool for the fossil fuel industry? And, on a rapidly warming planet, just how dangerous is the message of social media influencers like him?
