A new study out led by the University of Zaragoza (UNIZAR) has confirmed through fossil testing that the temperature in the past has been cold and hot.
The resulting study involves climatic inferences being drawn on the basis of the fossil associations of small mammals whose remains have been deposited in El Mirón over the past 41,000 years. The fossil associations of these mammals reveal the composition of fauna living around the cave at the time, and have made it possible to develop a paleoclimatological and paleoenvironmental reconstruction of the environment.
The research shows that there have been seven periods of cooling and warming in the Cantabrian cornice over the past 41,000 years. An analysis carried out by other authors on data relating to pollen, marine isotope stratigraphy, and materials deposited by glaciers backs this up this result.
Only seven? We have had more cool and warm periods in Colorado in the last 20 years than that! Ooooooh, wait a minute, that must be because of man-made global warming, right? Otherwise it would be a comfortable 72 degrees all the time...
