New research shows the permanent rise of oxygen in our atmosphere, which set the stage for life as we know it, happened 100 million years later than previously thought.
A significant rise in oxygen occurred about 2.43 billion years ago, marking the start of the Great Oxidation Episode a pivotal moment in Earth s history.
An international research team including a UC Riverside scientist analyzed rocks from South Africa formed during this event. Findings, published this week in the journal
Extra 100 million years before Earth saw permanent oxygen rise

A billion years from now, as the sun heats up, the warmer atmosphere will break down carbon dioxide, killing off plant life, which in turn will shut off Earth’s source of oxygen.
All plant and animal life on Earth need oxygen to survive. According to a new study, a billion years from now, Earth’s oxygen will become depleted in a span of about 10,000 years, bringing about worldwide extinction for all except microbes. Image via Dikaseva/ Unsplash.
Take a deep breath. The air expanding your chest is mostly nitrogen and oxygen, the chief components of our atmosphere. Oxygen exists in our atmosphere thanks to the exhalation of plants, through the process of photosynthesis. A study released in March 2021 shows that – a billion years from now, as the sun heats up – plants will die off, taking with them the oxygen in our atmosphere that humans and animals need to breathe.
