Our world’s ocean is one interconnected and complex system. As carbon dioxide levels and global temperatures rise, that system can change in many different ways. Global and regional changes in ocean temperature, salinity, circulation, currents, distribution of nutrients, extreme weather, and El Niño patterns are part of the interconnected web of climate change in our ocean. Though the effects of climate change on ocean processes and circulation are different in different parts of the world, all of these effects are part of the broader picture of global climate change. As our ocean's patterns and processes change, we must find ways to lessen the negative impacts of these changes and protect the future of our ocean ecosystems. As stewards of our land and water, we need to work to better understand these changes, in order to plan and prepare for the future of coastal parks, marine resources, and human safety in a changing world.
