ELI5: What is the difference between the cyclical climate change seen during the Ice Age and the climate change we see today?

EDIT: look guys, I don't want to hear the climate change deniers. I just want help fleshing out comparisons between the Pleistocene and now. 
 I'm a history major with little more than laymans knowledge on the subject but as a part of my internship with the school's museum I'm running a booth for our family day Earth day this weekend and my focus is on Pleistocene megafauna because we have casts of a Columbian mammoth femur, atlas, and humerus that were found nearby. As a part of earth day I'm also comparing climate change then and now but was having difficulty consolidating my thoughts and making it understandable to the people coming through.
