Videos are trending on social media showing people holding a flame to snowballs in a bid to ‘prove’ it is fake. Extreme weather in US southern states like Texas has caught many by surprise, with at least 58 reported dead from the storm and millions left without power or running water. President Joe Biden has issued a major disaster declaration in response, dispatching federal aid to those in need. The recent snowstorms were actually predicted many weeks before by meterologists, who say it's linked to a phenomenon known as Sudden Stratrospheric Warming. This happens when the Arctic warms rapidly, disrupting a mass of cold air.
