1. Some of the infrared radiation is absorbed and emitted by the greenhouse molecules. The presence of greenhouse molecules  such as water vapour in clouds  and CO2 on Earth traps infrared radiation emitted by the Earth Surface for a longer period of time. Therefore, energy is recirculated within Earth’s atmosphere.

2. No, global warming not only results in the warming of the Earth’s atmosphere, but it can also cause erratic changes such as changes in the seasonal cycle, which has indirect impact on the ecological system. For example, the changes in the seasonal cycle can result in changes of breeding and migration seasons of the bird.

3. Water in the atmosphere can absorb microwave radiation, interfering with the detection of the intended object.

4. Air quality poses the most serious problem in the short run, as it results in immediate respiratory health problems, which are symptoms such as shortness of breath and coughing. Stratospheric ozone depletion poses the most serious problem in the long run, as constant ozone depletion causes penetration of ultra-violet radiation onto the Earth’s surface. When radiation penetrates skin of living organisms, it will cause skin cancer.

4. In Canada, the acid rain issue faced is contributed by the major sources of sulphur dioxide emissions, which are non-ferrous metal smelters, followed by coal-fired generators. Motor vehicles and, to a lesser extent, coal-fired generators, are the major sources of nitrogen oxides. About half the wet sulphate deposition in eastern Canada originates outside the country, and comes from the United States.
