Astrobiologists have revealed that habitable conditions on Earth will exist for at least another 1.75 billion years.
The research findings are based on our distance from the sun and temperatures at which it is possible for the planet to have liquid water.
Future Effects of Climate Change Could Be Predicted With The Help Of Earth's 'Deep Time'
Change in climate changes the way in which species interact with one another - a reality applicable not just to today or to the future, but also to the past, claims a new study.

The research used recently discovered planets outside our solar system (exoplanets) as examples and investigated the potential for these planets to host life.
The research was led by Andrew Rushby, from UEA's school of Environmental Sciences said that they used the 'habitable zone' concept to make these estimates - this is the distance from a planet's star at which temperatures are conducive to having liquid water on the surface.

Rushby said that they used stellar evolution models to estimate the end of a planet's habitable lifetime by determining when it will no longer be in the habitable zone.
He asserted that they estimate that Earth will cease to be habitable somewhere between 1.75 and 3.25 billion years from now and after this point, Earth will be in the 'hot zone' of the sun, with temperatures so high that the seas would evaporate.
Rushby said that a catastrophic and terminal extinction event for all life will occur at that time.
The findings have been published today in the journal Astrobiology.
