Carney Flood Event: 233 million years ago, a massive eruption of volcanic groups in western Canada. Massive amounts of carbon dioxide insulation gas were spewed out. The Earth's surface temperature rose to 40 degrees, evaporating massive amounts of water vapor, which eventually led to a heavy rain that lasted for 2 million years. Of course, it doesn't rain all the time, but there are 350 days of heavy rain throughout the year. 233 million years ago, a year on Earth was 420 days. The Earth's rotation is slowly decelerating. This heavy rain causes major floods every year in most parts of the world. Grasslands have largely disappeared and forests dominate.
