Climate change is a natural process, but human activities such as burning fossil fuels and producing aerosols exacerbate it. The greenhouse effect, caused by gases like carbon dioxide, is a major factor. Solar radiation may also play a role. The causes of climate change are debated, but some warn that it must be minimized for human livelihood.
Climate change is a natural process that causes global temperatures to fluctuate over a certain period. Some people believe that unnatural factors are also causes of climate change. Theories that climate fluctuations occur at worrying rates have sparked a growing desire to understand the factors.
A phenomenon known as the greenhouse effect is thought to be a major cause of climate change. The greenhouse effect occurs when certain gases, such as carbon dioxide, water vapor and methane, are highly concentrated in the atmosphere. These gases are believed to absorb radiation emitted by the earth’s surface. This causes the radiation to be trapped in the atmosphere. As a result, the Earth’s temperature rises.
Carbon dioxide is considered one of the major culprits of this global warming process. Many scientists believe that the oceans are natural storage of carbon dioxide. The amount that can be stored is affected by temperature. As the Earth warms up, theories suggest the oceans may store less carbon dioxide. When these increasing amounts of gas are released, they cannot escape into the atmosphere. This process of releasing and trapping becomes a cycle.
Humans are believed to be the aggravating causes of climate change due to a number of activities. The burning of fossil fuels such as oil, natural gas and coal is one of them. Burning these substances produces more carbon dioxide. Limiting the use of fossil fuels is assumed to have a positive effect on global warming.
Aerosols are another human exacerbation of climate change. Aerosols are small particles in the air that can raise or lower the temperature, depending on the type. Some aerosols, such as those produced by volcanoes, cause cooling and are unrelated to human activity. Other aerosols, such as smog and forest fire smoke, arise from people. These aerosols are said to have warming effects because they absorb the sun’s energy.
It was once believed that the sun’s output varies only slightly. More recent theories based on satellites containing radiometers suggest that solar radiation may have significantly higher variance. If variation in solar power were shown to be a constant reality rather than a trend, it would be logical to expect climate change, according to some scientists.
The causes of climate change is a topic that is surrounded by much debate. The problem has been analyzed by several professionals. Some of them completely reject the idea that significant climate change is taking place. Others warn that the rate of change must be minimized for the sake of human livelihood.
