One of the planet's mass extinction events was The Great Oxidation Event. Future lizard scientists will study our time period and coin it The Great Carbonisation Event!
But life probably will not make it that long. As the sun hurls more energy at the planet, Earth’s atmosphere will heat up, causing more water to evaporate from the oceans and continents. Water vapor is a potent greenhouse gas, and so it will trap even more heat. It may get hot enough in two billion years to boil away the oceans.
