Global warming deniers deny global warming, the climate change crisis and its human cause. I have 3 simple questions for them:
1.The Moon’s night temperature is -153C; Mars, -142C; Earth’s was +3C here last night. Why?
2.Would physicists, chemists and astronomers say that more greenhouse gasses (GHGs) in the atompshere will trap more heat from the sun?
3.The CO2 concentration in 1880 was 285 ppm; now, it is 387 ppm. Where did the extra 102 ppm come from?
To #1: Mar’s is farther from the Sun than the Moon but is warmer because it has an atmosphere with GHGs while the Moon has none. Earth has a much thicker atmosphere than Mars’, with even more GHGs. In fact, without global warming, the deniers wouldn’t exist.
To #2: YES, YES and YES.
To #3: Human activities.
