Don’t frighten the people, baslim! I looked up some data: The Sun’s luminosity will significantly alter the Earth’s atmosphere and thus its habitability within the next 1.1-3.5 gigayears (Kasting 1988). So we have another billion years before we really have to start worrying about it, which for a species only 100,000 years old is rather a long time!
