June heatwave threatens fish and insects

The UK's hottest June on record caused unprecedented deaths of fish in rivers and disturbed insects and plants, environment groups have warned. The BBC’s Climate Editor, Justin Rowlatt, was at Knowle Locks in Solihull looking at some of the effects of this heatwave on fisheries. Today’s Mishal Husain spoke to John Ellis, the national fisheries manager at the Canal & River Trust. He explained that when it’s warmer fish need more oxygen, but as the temperatures rise water holds less of it. Mishal also spoke to Emily Shuckburgh, the Director of Cambridge Zero, who emphasised the need for action on climate change. Image credit: Getty Images
