Right now, the temperature of the Earth is pretty much perfect for humans, at around 13.9 degrees Celsius, or 57 degrees Fahrenheit. Yes, that is much lower than “room temperature,” which is around 20 degrees C (or 68 F)—but remember, this is for the whole planet. That average temperature includes the surface of all the oceans as well as regions near the poles. So maybe 13.9 C isn’t that cold?
