Mass extinctions, rising temperatures, and changing glaciers may sound like current events, but Earth scientists are learning that this type of climate change is nothing new.
 
This week on Skepticality, Swoopy talks with Dr. Donald R. Prothero about his new book Greenhouse of the Dinosaurs: Evolution, Extinction, and the Future of Our Planet. Prothero discusses the links between the climate changes that have occurred over the past 200 million years.
 
Dr. Prothero also discusses "Ida," a 47-million year old fossil the media is hailing as yet another "missing link." Is Ida all she is hyped up to be — or is this Darwinius masillae just one more transitional fossil supporting the theory of evolution?
