Chronicles of Climate Change: Evolution & Glaciations
This short film takes you on an epic journey through deep time and it explores the very significant cold (glacial) climate events in Earth's distant past. These include the global-scale Snowball Earth glaciations in the late Precambrian, the Late Ordovician Glaciation, the Late Paleozoic Ice Age (Carboniferous to Permian), and the more recent Pleistocene Ice Age.
Each of these very cold climate events had a profound impact on the evolution of life on land and sea, in plants and animals. Incredibly, despite being put under enormous pressure during these cold events, which led to extinctions, life subsequently found a way to adapt and rebound in their aftermath. By the end of this film, we hope to have provoked some thoughts as to how life on Earth will react to future changes in climate. If you have any thoughts, feel free to share them below!
