The future of the Earth is closely linked to that of the Sun. Due to the accumulation of helium in the core of the Sun, the luminosity of the star increases slowly on the scale of geological time. The luminosity will increase by 10% over the next 1.1 billion years and by 40% over the next 3.5 billion years.
