In this episode, I talk about the types of evidence we use to understand past climates on Earth.  I talk about isotope evidence, fossils, paleomagnetism, speleothems, ice cores, tree rings, and written records.  This is about the evidence we use, rather than what the evidence showsThis is perfect when teaching a climate change unit. Interested in joining us on a trip?   Check out our field adventures here.Don't miss a thing!   Join our email list. Support the show
