Causes Of Climate Change

Most Important Cause Of Climate Change

Human action is the main cause of climate change. Individuals burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed tremendous regions of land from forests to farmland. Burning fossil fuels produces carbon dioxide, a greenhouse gas. It is called a greenhouse gas since it produces a “greenhouse effect”. As a result, the greenhouse effect makes the soil warmer, just as a greenhouse is warmer than its environment. Furthermore, carbon dioxide is the main cause of human-induced climate change. It stays within the air for an awfully long time. Other greenhouse gasses, such as nitrous oxide, stay within the atmosphere for a long time. Other substances only produce short-term impacts. Not all substances produce warming. A few, like certain aerosols, can produce cooling.

What Is Climate Change?

Climate change could be a long-term shift in climate conditions recognized by changes in temperature, precipitation, winds, and other indicators. Climate change can include both changes in average conditions and changes in variability, including, for example, extreme events.

The earth’s climate is naturally variable on all time scales. Be that as it may, its long-term state and average temperature are controlled by the balance between incoming and outgoing energy, which decides the Earth’s energy balance. Any factor that causes a sustained change to the amount of incoming energy or the amount of outgoing energy can lead to climate change. Distinctive components work on different time scales, and not all of those components that have been responsible for changes within the earth’s climate in the distant past are significant to contemporary climate change. Components that cause climate change can be partitioned into two categories ­- those related to natural processes and those related to human action. In addition to natural causes of climate change, changes inside the climate framework, such as variations are also components towards the worsening of climate change.

Ocean currents or atmospheric circulation can moreover impact the climate for brief periods of time. This natural internal climate variability is superimposed on the long-term forced climate change.

Natural Causes

The Earth’s climate can be influenced by natural components that are outside of the climate framework, such as changes in volcanic activity, solar output, and the Earth’s orbit around the Sun. Of these, the two variables significant to timescales of contemporary climate change are changes in volcanic activity and changes in solar radiation. In terms of the Earth’s energy balance, these components fundamentally impact the amount of incoming energy. Volcanic eruptions are episodic and have generally short-term impacts on the climate. Changes in solar irradiance have contributed to climate patterns over the past century. But since the Industrial Revolution, the impact of additions of greenhouse gases to the air has been over 50 times that of changes within the Sun’s output.

Human Causes

Climate change can moreover be caused by human activities, such as the burning of fossil fuels and the change of land for forestry and agriculture. Since the beginning of the Industrial Revolution, these human influences on the climate framework have expanded significantly. In addition to other environmental impacts, these activities alter the land surface and radiate various substances to the atmosphere. These in turn can impact both the amount of incoming energy and the amount of outgoing energy and can have both warming and cooling impacts on the climate. Furthermore, the overwhelming product of fossil fuel combustion is carbon dioxide, a greenhouse gas. The overall impact of human activities since the Industrial Revolution has been a warming impact, driven fundamentally by emissions of carbon dioxide and improved by emissions of other greenhouse gasses.

The build-up of greenhouse gasses within the air has driven to an improvement of the natural greenhouse effect. It is this human-induced enhancement of the greenhouse effect that is of concern since ongoing emissions of greenhouse gasses have the potential to warm the planet to levels that have never been experienced within the history of human civilization. Such climate change seems to have far-reaching and/or unpredictable environmental, social, and economic consequences.
