For many people, a logarithmic relationship can be a fairly abstract concept. It is hard to imagine the implication that it has on the strength of the greenhouse effect that corresponds to the amount of CO2
that humanity emits into the atmosphere. Here we present a visualization to explain in a simple way what we are talking about.
is a greenhouse gas. The presence of CO2
in the atmosphere traps a part of the infrared radiation that the Earth's surface emits into space. The total greenhouse effect of the Earth's atmosphere is about 30 °C, without this effect, the temperature would be -15 °C instead of +15 °C, the actual current average temperature.
Water vapor is the most important greenhouse gas. CO2 provides 3 °C of heating, that is, 10% of the total effect
When the concentration of CO2
increases, its greenhouse effect also increases, but not in a linear fashion, but logarithmically
. For each increase in concentration, the effect on temperature is less and less.
