The videos include personal musings and conclusions of the creators climate scientist Dr. Adam Levy and geologist Dr. Rachel Phillips. They are presented to our readers as an informed perspective. Please see video descriptions for references (if any).

Adam Levy and Rachel Phillips collaborated on two videos for their respective Youtube channels explaining the study A 485-million-year history of Earth’s surface temperature published by Emily J. Judd and colleagues in 2024.

Today's climate is changing. Fast. But what has happened in our planet's past? Have climate changes taken place long ago? In fact, there have been huge shifts in the planet's climate over the past hundreds of millions of years - from ice ages to temperatures far hotter than today. These have been triggered by everything from the evolution of plants to the asteroid that wiped out the dinosaurs. But throughout all this, there's one familiar variable: carbon dioxide. So what do the past half billion years reveal? And what does that mean for the climate change we're seeing today?
