As it is clear from the name, the change in climatic conditions on earth is called climate change. Although changes in the weather often occur, but climate change only happens if these changes persist for the last few decades to centuries. There are many factors that cause climate change. These factors are discussed in detail here:
Various causes of climate change
Climate change occurs due to changes in various external and internal systems. Let us know about them in detail:
Externally pressurised systems
volcanic eruptions
Volcanic eruptions, which produce more than 100,000 tons of SO2 in the Earth's stratosphere, are known to affect the Earth's climate. These explosions keep the Earth's atmosphere cool because these gases emit from them obstructing the transmission of solar radiation to the Earth's surface.
Solar energy production
The rate at which the Earth receives energy from the Sun and the rate at which this energy is emitted back into the climate determines the climate balance and temperature on the Earth. Any change in the production of solar energy thus affects the global climate.
plate tectonics
The motion of tectonic plates reconstructs land and oceans over a period of millions of years, creating new topography. This activity affects climatic conditions globally.
Change in earth's orbit
Changes in the Earth's orbit change the seasonal distribution of sunlight, which affects the amount of sunlight reaching the surface. There are three types of orbital changes, these include changes in the eccentricity of the earth, changes in the tilt angle of the axis of rotation of the earth, and the eccentricity of the Earth's axis, etc. These lead to the formation of Milankovitch cycles which have a great impact on the climate.
Human activities
The CO2 generated due to combustion of fossil fuels, pollution of vehicles, deforestation, animal agriculture and land use are some of the human activities that are changing the climate.
Effect of mechanism of internal forces
life
Life plays an important role in creating carbon emissions and negative changes in the water cycle. It also has an impact on climate change. It also affects the formation of clouds, evaporation, and climatic conditions, besides providing many other negative effects.
Ocean-atmospheric variability
The atmosphere and the ocean together bring changes in the internal climate. These changes can last from a few years to a few decades and adversely affect global surface temperatures.
Effects of climate change
Climate change is having a negative impact on the Earth's environment. These effects are described here:
Impact on forests
Forests play an important role in maintaining the balance of carbon dioxide in the environment, as they absorb carbon dioxide. However, many species of trees have become extinct due to the environment being unable to cope with the constantly changing environment. The mass extinction of trees and plants has led to a decrease in the level of biodiversity which is a bad sign for the environment.
Effect on polar regions
The north and south poles of our planet are important for regulating its climate and the changing climatic conditions are also adversely affecting them. If these changes continue in a similar way, it is anticipated that life in the polar regions may be completely extinct in the coming years.
Effects on water
Climate change has given rise to some serious conditions for water systems worldwide. Due to the changing weather conditions, the nature of rainfall is changing all over the world and due to this, flood or drought conditions are being created in different parts of the earth. The melting of glaciers is another important issue due to the rise in temperature.
Impact on wildlife
The number of various wild animals including tigers, African elephants, Asian rhinos, adley penguins and polar bears has been recorded and most of these species have reached the verge of extinction as they are unable to cope with the changing seasons. Huh.
The conclusion
The environment is being negatively affected due to changes in climate. According to the researchers, human activities during the last few decades have played an important role in accelerating this change. In order to control climate change and maintain a healthy environment on earth, the effects caused by human activities on the earth need to be controlled
