Scientists have calculated when life on Earth will end

Scientists have presented new scientific calculations on how much longer life on Earth can last. According to the study, the biosphere in its current form could persist much longer than previously estimated—approximately 1.8 billion years longer.

JGR Atmospheres The study, published in the scientific journal, notes that plants and the process of photosynthesis on Earth are much more stable than suggested by previous theories. This means that the ecosystems that form the basis for life could continue to function for billions of years.

Scientists note that the Sun is gradually becoming brighter and hotter as part of its natural evolution. Today, it emits about a third more energy than it did 4.5 billion years ago. Experts estimate that the Sun will continue to heat up for another 5 billion years before moving to the next stage of its life cycle.

Interestingly, in 1982, British scientist James Lovelock estimated that photosynthesis-based life on Earth would only last for another 100 million years . The new study extends this period by nearly 18 times , estimating it at 1.8 billion years.

However, not all scientists believe this scenario will come to pass. Astrobiologist Jacob Haqq-Misra believes that greenhouse gases released into the atmosphere as a result of human activity could accelerate global warming, posing a threat to the biosphere much sooner.

Experts emphasize that if global climate change continues at its current pace, the natural environment on Earth could face serious risks within 6,000–7,000 years .

The authors of the study remind us that photosynthesis is the foundation of life on Earth. If temperatures reach extreme levels, this process will stop. As a result, plants will disappear, the food chain will collapse, and life as we know it will no longer be able to exist.

At the same time, the scientific community emphasizes that the fate of the Earth depends not only on natural cosmic processes but also directly on humanity's impact on the climate.
