Answer:
In the given case, Mike needs to study the emission of greenhouse gases.
Step-by-step explanation:
A gas, which captivates and discharges radiant energy within the thermal infrared range is considered as a greenhouse gas. The greenhouse gases result in a greenhouse effect. The main greenhouse gases in the atmosphere of the Earth are carbon dioxide, water vapor, ozone, methane, and nitrous oxide.
The greenhouse gases envelopes the Earth like a blanket. With more burning of fossil fuels like natural gas, coal, and oil, the blanket turns denser, thicker, and permits less escaping of heat. The trapping of heat takes place within the blanket of greenhouse gases and the Earth turns too much warm eventually resulting in a change in climate.
