Why is ozone layer depletion at its maximum at the South Pole? Does global warming affect the ozone layer? How does ground-level ozone affect the environment? What results from stratospheric ozone depletion? What happens when the ozone layer is damaged?
Step 2:To gain access to the capacitor, remove the service panel over the back rear portion of the unit or the service panel on the front of the unit below the door, as detailed later for disassembly. The capacitor is located in a housing on the top of the motor/compressor unit; it ...

In 1987 the Montreal Protocol was introduced and later signed up to by 120 countries who agreed to half their CFC emissions by the year 2000. We now know that apart from destroying the ozone layer, CFCs contribute significantly to the greenhouse effect. Even though they have been banned, ...
UV radiation has multiple levels; for example, UVC rays are the most harmful to the skin and eyes, but the ozone layer blocks many of the rays. UVA rays play a considerable role in causing skin damage and aging. The wavelengths of UVA rays are long and are, therefore, less harmful than...
Floating up into the stratosphere (the upper atmosphere), they rapidly damaged Earth's ozone layer: the natural sunscreen that helps to protect us from the Sun's harmful ultra-violet rays. Most modern air conditioners avoid CFCs (now banned in many countries under a global agreement called the...

Do you know the effects of global warming?Paul Souders / Getty Images Global warming was once an uncommon term used by a few scientists who were growing concerned over the effects of decades of pollution on long-term weather patterns. Today, the idea of global warming is well known, if not...
You see, the ozonosphere, which helps protect us from the suns ultraviolet rays, has been damaged by pollution in the air. When the ozone layer gets too thin, it can cause an increase in skin cancer and other problems. W: But is there anything we can do to solve the problem? A: ...
It was banned after the EPA discovered that it depletes the ozone layer. Vehicles manufactured pre-1995 often use R-12, but you can retrofit them with an R-134a system. R-134a (HFC-134a): Your vehicle likely uses R-134a (also called HFC-134a). This refrigerant surfaced to ...
