The ocean is our planetβs life-support system and is a critical part of Earthβs climate. It is also a source of hope and holds a wealth of opportunity to help solve many of humanityβs most pressing challenges, including climate change. The Ocean Pavilion is returning to the Blue Zone in Dubai with a fundamental message to COP delegates and attendees: The ocean is fundamental to the planetary systems that regulate our climate, and that delicate balance is increasingly in peril due to human activity. But with careful, science-based solutions and informed policy decisions, the ocean could restore balance and help us chart a path out of our climate crisis.
