If you had access to a time machine, where in time would you travel to undertake your research and what data would you collect while you were there? Although this session involves play acting, the serious intent of this exercise is to explore important time intervals that help inform us about Earth and climate interactions, and to think about what data is most important to our understanding of these interactions - without being constrained by either the geologic record or proxy availability. With this in mind, this session would help our field think broadly and creatively about potential research for the next century. The session will culminate in audience participation in a printed geologic time line and a gallery walk.
