- Can radiation from a cold body increase the temperature of a warmer body?
- Are the Stefan-Boltzmann and Planck Laws applied correctly in calculating the greenhouse effect?
- How can radiation from a cold body not be thermalized [cause an increase in temperature] of a warmer body?
- How does quantum mechanics explain why a cold body can't make a warm body warmer still?
- How do photons "know" how to do this?
- Does water vapor warm or cool the planet?
- Do clouds warm or cool the planet?
- Why are cloudy nights warmer?
- Do clouds cause 25% of the greenhouse effect as claimed?
- In addition to the "back-radiation" misconceptions listed above and below, a prior HS post explains why global warming also cannot be explained by an increase of the "effective radiating level"
While water vapor and other greenhouse gases DO have a profound effect upon climate, the effect is a slowing of cooling at night and slowing of warming during the day [from evaporation, clouds, and enhancement of convection], resulting in a much more benign climate with decreased diurnal temperature range and decreased temperature extremes.
Compared to the moon, which has a mean daytime temperature of 123C and mean nighttime temperature of -233C [a diurnal range of 356C!], the presence of Earth's atmosphere serves to greatly cool during the day and retain warmth during the night to reduce the diurnal temperature range to only ~11C. The global land diurnal temperature range has decreased over the past 110 years with the increase of greenhouse gases, as expected from a slowing of cooling at night and/or slowing of warming during the day.
