120 Seconds of Science with Doc Ryan
Below are the first seven installments of the “120 Seconds of Science with Doc Ryan” video series. These videos are designed to offer teachers quick, engaging tools for introducing climate science topics to their students.

Doc Ryan, who holds a doctorate degree in geology and climate from CU-Boulder, is available for
school assemblies, classroom presentations and Q & A Skype sessions with science students –
during which he brings STEM learning to life. One of his signature presentations, “Spinning
