We are moving through a critical decade for ocean conservation, where acknowledging and acting on the link between the ocean and climate change has never been more pressing. In addition to encouraging local support for conservation initiatives, there is an urgent need for young people to understand the key principles of climate change and how this is impacting the ocean. It is equally important for them to feel hopeful about securing a more sustainable future considering this immense global challenge. Marine climate change issues are poorly communicated despite the central role of the ocean in the carbon cycle, where it dissolves more than 1 million tonnes of man-made CO2 every hour.
