NASA has calculated that life on Earth has around 1.5 billion years left before it becomes uninhabitable. While the planet will be consumed by the Sun in about 5 billion years, the real threat comes sooner. As the Sun ages, it gradually gets hotter and brighter, leading to rising global temperatures. This will cause intense heatwaves, droughts, and the eventual evaporation of Earth\u2019s oceans. As more water vapor, a potent greenhouse gas, enters the atmosphere, the planet will experience a \u201cmoist runaway greenhouse effect,\u201d accelerating global warming beyond the point where life can survive.<\/p>\n
In Earth\u2019s final stages, it will resemble Venus, with scorching temperatures and an atmosphere stripped of moisture. The Sun, by then a red giant, may engulf the planet. This prediction highlights the finite nature of Earth\u2019s habitability, underscoring the need for space exploration and the search for new homes for humanity.<\/p>\n","protected":false},"excerpt":{"rendered":"
