The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium. in IPCC TAR).

The radiative forcing from these changes in concentrations can be easily calculated using standard formulas (from Etminan et al, 2016 which supersede the slightly simpler ones from IPCC TAR), as about 2 W/m 2 for the CO 2 change and 0.65 W/m 2 for CH 4. W/m² (to about 60% of the CO 2 effect since 1750). References.

One good example of the nexus between global warming and local pollution is ground-level ozone. To make matters worse, NOx contributes to the formation of ground-level ozone and secondary PM2.5, In 2016 it accounted for 57% of total toxic emissions from larger sources in the city, including benzene and other known carcinogens.

Compounds that can absorb energy are important because they alter the radiative balance of our Earth’s atmosphere.
