Global Warming


If you thought the outer atmospheres of the giant planets: Jupiter, Saturn, Uranus, and Neptune are cold think again. You are not unfounded, models suggest a temperature of -73 C would exist, but Voyager found temperatures of + 700 C (1000 K)!

We now know the atmosphere of Uranus has changed from 750 K to 550 K in 20 years and since the year 2013 the temperature as rebounded by 50 kelvin per year.

Recent studies may have found an answer. Could it be storms?
