Research shows Earth’s ancient climate warns of urgent action

Scientists have studied the ancient history of the Earth and found that it will take serious action to reduce fossil fuel emissions so that our climate does not reach prehistoric levels of warming.

An international team of researchers has looked back in time to piece together the most complete history of carbon dioxide (CO2) levels on Earth over the past 66 million years to date in a new study. In this work, they sought to strengthen our understanding of the relationship between CO2 and climate, show how things have really changed since dinosaurs last walked planet Earth, and look at the future of Earth as changing of the climate continues to threaten our planets and their inhabitants.
