"The observed climate variations in the 20th century can be explained by a combination of natural and human causes. There are three distinct natural causes of climate variations: volcanic eruptions, variations in solar activity and El Niño (5):
Strong volcanic eruptions, such as those of Mt. Pinatubo in the Philippines in 1991, expel enormous quantities of dust high into the air. This dust remains in the atmosphere for several years and reflects sunlight back into space. As a result, the Earth’s surface becomes cooler.
The second natural factor, solar activity, is not constant and, consequently, the quantity of energy which reaches the Earth from the Sun varies slightly over time. This will in turn affect the temperature on Earth.
The third natural factor is El Niño. The temperature of the seawater in an area to the west of Peru is abnormally high once every 3–7 years, which causes changes in the ocean circulation patterns. This change eventually leads to abnormal global weather patterns and affects the average global temperature.
