NASA warns: Life on Earth will end in a billion years!

A recent study by NASA's supercomputer has provided significant insights into when life on Earth might end. According to the researchers, who worked in collaboration with Toho University in Japan, Earth will become uninhabitable in about a billion years. The main reason for this is the increasing luminosity of the Sun, which will gradually lead to extreme surface conditions that will make life impossible. This means that life on Earth is expected to end around the year 1,000,002,021, when oxygen levels in the atmosphere fall dramatically, which has already reached a critical point, comparable to conditions before the Great Oxygen Catastrophe about 2.4 billion years ago.

The researchers fear that the increase in solar radiation will result in an increased breakdown of carbon dioxide. This affects the plants' oxygen production, ultimately leading to a significant loss of oxygen. The study suggests that it will not be extreme heat that will be the biggest problem, but rather the depletion of vital oxygen, which will leave Earth in an uninhabitable state. Anthropogenic factors and possible asteroid impacts were not taken into account in this study, which clearly puts the focus on the natural development processes. The scientific evidence emphasizes the need for preventive measures to counteract the effects of climate change.

The influence of climate change

At the same time, man-made climate change is an accelerating factor. Global warming is leading to massive changes that are already visible today. According to NASA scientists, this increase in temperature, combined with a falling oxygen limit, will result in drastic changes in Earth's atmosphere. These changes are gradual and irreversible and are already heralded by increased intensity of solar storms and coronal mass ejections. These phenomena have a direct impact on the Earth's magnetic field and contribute to the further reduction of atmospheric oxygen.

To meet the looming challenges, research is being intensified to find habitable planets in the universe. Technologies such as closed life support systems and artificial habitats are increasingly being considered as possible approaches to ensuring human survival. Plans for long-term space colonization, including Mars missions from NASA and SpaceX, are high on the agenda.

Forecasts for the future

A report from the Intergovernmental Panel on Climate Change presents five possible scenarios for the future, looking at different socio-economic pathways and their impact on emissions. These scenarios range from optimistic (SSP1) to gloomy (SSP3 and SSP5), with the optimistic variants being in line with the Paris Agreement. Drastic reductions in fossil fuels could result in global emissions reaching zero by the middle of the 21st century.

• SSP1-1,9 (optimistisch)
• SSP1-2,6 (optimistisch)
• SSP2-4,5 (moderat)
• SSP3-7,0 (düster)
• SSP5-8,5 (absurd)

Under these scenarios, the temperature increase may vary between 1.4°C and 2.7°C by the end of the century. Optimistic assumptions offer the prospect of strong economic growth and improved living standards, while dire scenarios predict catastrophic impacts from the climate crisis. Given these developments, future developments require a radical rethink in the global community, particularly regarding emissions.
