Mass Extinctions and Climate Change - Sierra College Insights
Most people are familiar with the mass extinction that killed the dinosaurs 66 million years ago. Have you heard about the other “Big Five” mass extinctions that nearly wiped out all of life on Earth? Amazingly none of these other extinctions show direct evidence for an extraterrestrial impact. Instead the tie that binds all the mass extinctions is climate change. One of the most remarkable fossil records of a major mass extinction is located along the Sierra in western Nevada. The Nevadan fossil record shows a time of increased greenhouse gases, changing oceans, and collapsing ecosystems. With biologists and ecologists proposing evidence that we are in the “Sixth Extinction” find out how the past might be able to tell us more about our present and future.
