Extreme CO2 greenhouse effect heated up the young Earth

New research suggests that high CO2 levels in the atmosphere may have warmed the young Earth's climate, accounting for apparent anomalies such as hot seawater temperatures above 70°C. The study proposes a plausible explanation for these phenomena, indicating temperatures closer to 40°C when considering ocean composition changes.

Evolution: Building blocks of life

Researchers at Ludwig-Maximilians-Universität München have identified a plausible reaction mechanism for the production of key components of RNA under conditions similar to those on the young Earth. The discovery validates a pathway that could explain how chemical evolution proceeded before the formation of the first cells.
