Answer 1

The amount of sunlight emitted by the sun is the same, but the presence of greenhouse gases traps solar heat so it feels hotter.

Explanation:

The sun still emits the same amount of sunlight daily and the earth receives its same quota.

However, the increase in air pollution especially SPM (suspended particulate matter) of different sorts, especially in urban or industrial localities will reduce the amount of perceptible sunlight.

The same air pollution, mainly the greenhouse gases like carbon dioxide, carbon monoxide, chlorofluororcarbons, methane, etc, traps solar heat instead of allowing it to be reflected from the earth. This causes the troposphere (the lowest layer of the atmosphere or air) to retain heat close to the earth's surface, in turn warming the lithosphere (land masses) and hydrosphere (oceans and other water bodies).
