Question 1:
The presence of greenhouse gases absorbs and traps the energy radiated by the Earth, thus heating up the atmosphere. Clouds are composed of water vapor, which is a strong greenhouse gas, thus contributing to the heating up of the atmosphere, so the Earth is not cooling rapidly.
Question 2:
The statement is incorrect. Global warming will upset the climate system and cause extreme weather. Some places will experience extreme heat waves, droughts, while other places will experience excessive precipitation and colder-than-before weather. Despite the image showing the people experiencing extreme cold weather and are in knee-deep snow, there is still global warming, and it is the cause of the extreme weather the people in the image are experiencing.
Question 3:
The absorption of microwaves by water molecules will interfere with detection of intended objects. This is since the water molecules will absorb the microwaves instead. Thus, the design in unsuccessful.
Question 4:
In the short run, the most serious situation is the bad air quality. The particles in the air will cause direct health problems such as respiratory problems.
Global warming has more drastic consequences, due to the rising sea levels caused by glacial retreat, and extreme climates. This will affect the survival of living organisms.
Depletion of ozone directly affects a certain area of the Earth. There are precautions then individual can take to prevent the UV rays from affecting us. Such as sunblock and sunscreen)
