The movement of heat in the ocean, through currents, affects climate seen around the globe. Take a look at this image; red arrows show warm water currents and where they move. Blue arrows show cool water currents.
In the Atlantic, warm water from the Gulf Stream extends all the way to England. This is why England typically has a mild climate in comparison to Canada, which is just as far north.
This section of the script is intended to fill in the public’s “cognitive hole” around the climate as a system. While experts consistently describe climate as an integrated system, the public treats the ocean, atmosphere, climate, and weather as discrete entities and lacks an understanding of these concepts as part of a larger system. The frame elements of the Visual and the Explanatory Examples work together to give the public a more robust understanding of how these elements are interrelated.
You can add or substitute local examples of how the ocean affects the climate. For example, there is a Mediterranean climate in California due to the California Current bringing down cool water from the north Pacific.
