Research needs for climate and global change assessment, Chapter 29
Climate change is no longer an issue for consideration in the future. Climate changes are being observed all over the U.S., from Miami to Arctic Alaska, and from the top of our atmosphere to the depths of our oceans. This report documents changes already observed and those projected for the future....
