There exists no precise definition of Climate so it is always described in relation to the place. Every place has its

own typical climate, as in, some places are covered in snow eternally and some are hot, dry, and arid. Climate

also varies with the season. However, climate change refers to a significant change in the usual climate of a

certain place in the sense of a change in the annual precipitation or the change in temperature or humidity, etc.

Due to the factors, some natural like the reduction of distance between the sun and the earth or some human

errors like emitting greenhouse gases, the temperature would soar thus melting the icebergs, rising sea level,

etc. While aiming for the Zero target is surreal, the Net-zero target is a trade-off. Net-zero does not actually cut

down on the emissions but tries to countervail the carbon emissions by carbon credits or sequestration or

methods like large-scale use of hydrogen and de-carbonization of electricity.
