What evidence is there that the earth is actually warming up?
! tysm ; )

a. as the temperature increases, the kinetic energy of the gas molecules increases & the molecules move faster & further away from each other.

b. if you decrease the temperature of a fixed amount of gas at constant pressure, the combined gas law reduces to charles's law. in this case, volume will also decrease.

not only is it colder, it also becomes darker, less salty, and more dense.
