If you want to see the effects of real global warming, you don’t have to look any further than our sister planet Mars. Once a warm, wet planet with oceans and rivers whose beds still crisscross the Martian landscape, it’s now cold and dead and the only water we’ve found thus far is frozen in its polar ice caps.

Global warming made Venus hot enough to melt lead, and it also made Mars cold enough to have a CO2 ice cap.
