Rockpools and ocean acidification - Planet Earth Podcast - 10.09.23

Everyone loves a rockpool, and Sue Nelson nearly takes a dive into one in this week's podcast while finding out about the riches they contain. She visits the Anglesey coast of north Wales to learn what these mini marine laboratories can tell us about the value of biodiversity. The effects of climate change range from rising temperatures and higher sea levels to extreme weather and mass extinctions. Richard Hollingham reports from the Plymouth Marine Laboratory where scientists are investigating another, hidden process - increasing ocean acidification. And finally we learn how scientists are using pan scourers to find out how communities of marine creatures might respond to chemical changes in our oceans.
