Which gas is responsible for man made climate change?

Dear Student,
​​​​​​Answer to your question is given below:
Greenhouse gases are responsible for man made climate change. Greenhouse gases are those that absorb and emit infrared radiation in the wavelength range emitted by Earth. Carbon dioxide (0.04%), nitrous oxide, methane and ozone are trace gases that account for almost one tenth of 1% of Earth's atmosphere and have an appreciable greenhouse effect and thus are responsible for man made climate change.
