Hot water: why Ireland's marine heatwave signals danger

Last month saw a spike in temperature in Irish waters, an “unheard of” marine heatwave which raised sea temperatures by four to five degrees.Hotter seas have already brought previously unknown species to our shores - and driven away the fish that our fishing industry relies on. And that can only get worse as the seas heat.Environmentalist and activist Saoirse McHugh explains why warming seas is a crisis that needs to be addressed urgently, and Kevin Flannery, marine biologist and founder of the Dingle Oceanworld aquarium, talks about the new species now coming into Irish waters and the severe challenges ahead for our coasts, our coastal communities and our fishing industry.
