"This report will discuss Earth's systems piecewise, beginning with the physical systems of Earth's atmosphere, sea, land, and ice, then focusing on life on Earth, and ending with, perhaps, the most challenging and dynamic piece of all -- people. It's important to realize that all of the pieces of the climate puzzle are interconnected, and all of the pieces are necessary to gain a full understanding of climate variability and change."
