In a new study, researchers from Harvard University found that during these epochs of extreme heat, Earth may have experienced cycles of dryness followed by massive rainstorms hundreds of miles wide that could dump more than a foot of rain in a matter of hours. Little is known about how the atmosphere and climate behaved during these so-called hothouse periods. Earth likely experienced these temperatures at various times in the distant past and will experience them again hundreds of millions of years from now as the sun continues to brighten. Now, imagine an Earth 20 to 30 degrees Fahrenheit hotter than today. Today, we are experiencing the dramatic impacts that even a small increase in global temperatures can have on a planet’s climate.
