enormous periods of time, even small changes in the Sun’s brightness can have major consequences for Earth’s environment.
Eventually, the increasing heat will make Earth’s climate increasingly difficult for life to survive.
Earth Could Lose Its Oxygen
One of the most important findings discussed in the article concerns Earth’s atmosphere.
Scientists used mathematical models and computer simulations to examine how the planet’s atmosphere could change as the Sun becomes brighter.
According to the study discussed by the article, Earth’s atmosphere could remain relatively stable for roughly another 1.08 billion years, although there is considerable uncertainty around this estimate.
As the Sun becomes brighter and Earth’s environment changes, biological processes that help maintain atmospheric oxygen could eventually decline.
Plants and other oxygen-producing organisms would gradually struggle to survive under increasingly difficult conditions.
As a result, atmospheric oxygen levels could eventually fall dramatically.
Most Complex Life Would Eventually Disappear
