Science: More extreme weather, 'fast fashion' fix

Science commentator Laurie Winkless joins Kathryn with three new studies: the first focuses on what climate change is set to do to New Zealand's weather patterns in the coming years. Researchers in the US have found a way to make it easier to separate out fibres in textile waste. Could it provide a solution to how to recycle the world's annual 92 million tons of textile waste? And a Greek study has assessed how effective 30 km/h speed limits have been in European cities. Spoiler alert: they've been effective, and even won over the public. Laurie Winkless is a physicist and science writer.
