Question Q3GS1GS1

Explain the concept of heat budget & the role in maintaining the earth's temperature. How does the greenhouse impact the heat budget of the earth's atmosphere?

Open scan (p.8)

Main Body

Heat budget refers to the balance between incoming (short wavelength) ultraviolet radiation and outgoing (long wavelengths) Infrared radiation. Through heat budget earth maintains its temperature.

[Diagram showing short wavelength incoming and long wavelength outgoing radiation interaction with earth]

Short wavelength [incoming] => Reflected Radiation, Direct Reflected by atmosphere, earth, Absorbed by earth

Long wavelength [outgoing] => earth to space (Convection) to space [Emitted by earth]

Role is maintaining temperature

1Clouds : Some wavelengths absorbed & suffered by clouds in both direction
2Atmosphere : many particles

Effect of greenhouse gas on heat budget

1More greenhouse gases in atmosphere [Block] the radiation emitted by earth, which are going to space.
2Temperature increases : overall it leads to global warming
3Disbalance between incoming & outgoing radiation causes issues like melting glaciers, extreme weather events e.t.c
4Post industrial revolution temperature of earth has increased by more than 1.5°C.

Greenhouse gases have negative impact on heat budget & must be curtailed.

UKA absorbed just also absorb and emit radiations.

3Earth surface : It absorbs short wavelength & emits large wavelength.
