Last month saw a spike in temperature in Irish waters. An “unheard of” marine heatwave – defined as a period of persistent anomalously warm ocean temperatures, which can disrupt ecosystems – raised sea temperatures by four to five degrees.
The marine heatwave in our North Atlantic waters is classified as “extreme” by the US National Oceanic and Atmospheric Administration - and man-made climate change is at least partially to blame.
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 if seas continue to heat.
On today’s In the News podcast, environmentalist and activist Saoirse McHugh explains why warming seas is a crisis that needs to be addressed urgently.
