Global warming refers to the regular increase in the average temperature of the Earth's surface that has resulted in an increase in the concentration of greenhouse gases.
Greenhouse gases such as CO2, CH4, and CFCs allow sunlight to enter but block longer wavelength heat radiation.
The radiation that is absorbed returns to the earth's surface and heats it. This cycle continued.
Measures to solve global warming:
Reduced deforestation means halting the conversion of planted areas into non-planted areas, or in other words, halting the cutting down of trees that provide us with clean air and a healthy environment, as well as preventing various diseases.
Afforestation is the process of planting more trees or restoring a forest.
