Bad news: it could go out long before the sun settles our account.
For decades, scientists have assumed that the fate of humanity will be decided at the same time as that of the Earth, when the Sun transforms into a red giant that will swallow the planet. In fact, life in general will die out long before that, since the heat will be too intense to be bearable.

This scenario is supposed to take place in 7.5 billion years. But a new analysis calls into question the ability of the human species to exist more than 250 million years.
Various developments threatening humanity
Researchers have used a supercomputer, which they have provided with a large amount of data, to determine the time remaining for humanity based on various factors. Among them is plate tectonics, which will end up transforming the planet into a supercontinent in about 250 million years. This is the first point that could, according to the supercomputer's calculations, make the Earth “inhospitable”: we are therefore far from 7.5 billion years.

Added to this is the evolution of the Earth's atmosphere, which will also complicate things: solar heat will intensify, as will volcanic activity and the release of gases that are trapped in the permafrost, but which will eventually come out one day. All of this will contribute to increasing the CO2 level, and therefore making the Earth's atmosphere unbreathable.
And of course, the climate changes that we are beginning to see strongly today are also to blame, particularly in the rapid melting of permafrost, rising waters and temperatures. All this contributes to some rather bleak predictions.
Solutions still non-existent
The scientists behind the study readily admit that “predicting what will happen in 250 million years is a challenge.” However, the scenario currently being considered has researchers eager to find solutions to try to limit the damage. But questions remain: is it possible, and if so, how?

Continental drift is one of the uncontrollable elements, but others can be, particularly with regard to current climate change. The problem of pollution on a global scale can no longer be ignored, but solutions are still needed to reduce it and regulate rising temperatures. To this end, researchers around the world are mobilizing, but to date, no concrete solution has yet been found.

A race against time
Time is running out for scientists desperate for solutions. Humanity faces multiple, interconnected threats. Efforts to combat climate change are crucial.
Local and global initiatives are needed to reverse current trends. It is imperative to reduce CO2 emissions and find methods to capture and store this gas. Current technologies must be improved to meet future challenges.
Governments and citizens must cooperate for a sustainable future. Future generations depend on the decisions made today. What actions will be needed to ensure the survival of our species?
