Climate Change...

This is a figure that I found that describes the process of carbon dioxide with the ocean. The paragrah below does a good job in explaining it. I thought it was interesting as a follow up to what we discussed in class on Monday about climate change and carbon dioxide levels as we dicussed last week. The explanation below it says:

There is ongoing chemical "dialogue" between the ocean and atmosphere that influences regional and global climate change in many ways. Sea spray and water vapor from low clouds ultimately cool temperatures at the surface. Meanwhile, desert dust and carbon dioxide settle into the ocean and act as a "fertilizer" to stimulate the growth of phytoplankton, thereby enhancing the ocean's ability to absorb carbon dioxide from the atmosphere- a process kown as the "biological pump". Over geological time, more than 90 percent of the world's carbon has settled into the deep ocean.
