The Future of Earth: A Timeframe Analysis

Earth's demise is inevitable as the sun ages and evolves. While the planet has approximately 4.5 billion years before the sun becomes a red giant and engulfs it, Earth will become unlivable for most organisms in about 1.3 billion years due to the sun's natural evolution. Humans could drive themselves to extinction within the next few centuries if climate change is not mitigated. Extreme heat, evaporation of oceans, and the shredding of Earth due to the sun's gravity are some of the factors that will make the planet uninhabitable. The next hundred years are crucial for human life on Earth due to the imminent threat of climate change.
