As part of the on-line ecosystem ecology course I am putting together, I uploaded a series of lectures on the National Climate Assessment.
In total, about 30 minutes of summarizing some of the main points about changes in climate that were presented in the draft version of the National Climate Assessment.
It's still one of the most amazing scientific documents one can read.
If you don't read the document, it couldn't hurt to view this.
