NASA numbers have a few billion years earlier than the solar kills us all

A team of researchers working with NASA has finally figured out when the sun will burn all the oxygen on our planet, destroying all life on earth. By their calculation, it will happen somewhere around the year 1,000,002,021. If you’re still on the waiting list for Hamilton tickets, you may need to plan accordingly.

In a research report released Monday, the team describes the final moments before Earth loses its ability to support life as we know it:

We find that future deoxygenation is an inevitable consequence of increasing solar fluxes, while its precise timing is modulated by the exchange flow of reducing power between the mantle and the ocean-atmosphere-crustal system.

In other words, in about a billion years (we’re not sure if these are leap days or government holidays) the slowly increasing solar radiation will have reached a point where our atmosphere cannot return.

The team came to this conclusion after modeling and running an algorithmic simulation hundreds of thousands of times. According to a press release from Tohoku University, one of NASA’s project partners:

Since the modeling of the future earth development inherently involves uncertainties regarding the geological and biological development, a stochastic approach was chosen, which enables the researchers to obtain a probabilistic assessment of the life span of an oxygen-containing atmosphere.

[Kazumi Ozaki, Assistant Professor at Tohoku University] The model has been run more than 400,000 times, varying the model parameters, and it has been found that Earth’s oxygen-rich atmosphere is likely to last a billion years (1.08 ± 0.14 (1σ) billion years) before the atmosphere passes through rapid deoxygenation to the early earth is reminiscent of the great oxidation event about 2.5 billion years ago.

This, of course, is the opposite of man-made climate change. It is relatively easy to predict when the sun will destroy our planet since the sun is on a fairly steady arc. The current climate crisis is, as the vast majority of climate researchers agree, unnatural and represents a deviation when compared to data representing the 2.5 billion years that our planet had an atmosphere before humans appeared.

The bad news is that our planet is likely to become uninhabitable long before the sun suffocates all of Earth’s plant life and then burns up its atmosphere. But the good news is that if we are smart enough to solve our current problems, we have a billion years left to figure out how to stabilize the star that gave us life.
