It's not academic

I’ve heard a great deal of "so what?" about climate change, lately. Many people hear terms like "general circulation model", "albedo", and "aeronomy", and shrug their shoulders. Even as physical sciences go, these concepts can be fairly abstract. Moreover, we all remember hot days and cold days, and we’re fairly hard-pressed to remember how many of each we had last year. The reader can’t look out the window and "see" climate change.
Or can we? Climate drives a dizzying array of physical and biological processes. It’s impossible to overstate the relationship between climate, ecology, and adaptation. I’ll spare the reader my normal purple prose, and instead focus on this image.
This MODIS image published by NASA shows African dust blowing across the Atlantic Ocean, to be deposited in the Caribbean Sea. Higher temperatures yield more airborne African dust, and more energetic winds to carry it. This dust clouds the clear Caribbean waters, interferes with algae and coral, and has been linked to coral reef die-offs. The reef die-offs directly impact the livelihood of local fishermen.
I urge the reader to look past the sometimes confusing details of mathematics and science for a moment and focus on what scientists are actually concerned about: quality of life and livelihood across our human family. Is this not worth our time and consideration?
