A severe climate change event on Venus may have transformed an Earth-like climate to the current uninhabitable-to-humans state. We can learn a lot about climate change from Venus, our sister planet. Venus currently has a surface temperature of 840 degrees F (450 degrees C) – the temperature of an oven’s self-cleaning cycle – and an atmosphere dominated by carbon dioxide (96%) with a density 90 times that of Earth’s.
