Scientists have used a 3-D climate-carbon model to provide new insights about the temperature of the Earth at the time of life’s emergence on our planet. There are many important questions concerning the climate of the Earth at this time, included whether the planet was warm or cold. The temperature of the early Earth is critical to understanding the conditions under which the origins of life could have occurred.
The study, “A warm or a cold early Earth? New insights from a 3-D climate-carbon model,” was published in the journal Earth and Planetary Science Letters. The research was supported by NASA Astrobiology through the Exobiology & Evolutionary Program and the Virtual Planetary Laboratory node of the NASA Astrobiology Institute (NAI). Lead author, Benjamin Charnay was also supported as a 2016 Astrobiology Fellow for the NASA Postdoctoral Program.
