Climatic changes are primarily caused by natural factors such as volcanic eruptions, changes in solar radiation, and variations in Earth's orbit and tilt. However, human activities, particularly the burning of fossil fuels and deforestation, have significantly contributed to the current rapid pace of climate change. These activities release greenhouse gases such as carbon dioxide and methane into the atmosphere, which trap heat and lead to global warming. Other human activities, such as industrial processes and agriculture, also contribute to climate change by releasing pollutants and altering land use patterns.

Natural Causes:
- Solar radiation fluctuations: Changes in the amount of solar energy reaching Earth can affect global temperatures.
- Volcanic eruptions: Erupting volcanoes emit aerosols that can block sunlight and cool the planet.
- Ocean currents: Fluctuations in ocean currents can distribute heat around the globe, influencing local and regional climates.
- El Niño-Southern Oscillation (ENSO): A cyclical pattern of changes in the Pacific Ocean that can trigger extreme weather events and alter global temperatures.
Human-Induced Causes:
- Greenhouse gas emissions: Human activities such as burning fossil fuels, deforestation, and industrial processes release greenhouse gases (e.g., carbon dioxide, methane) into the atmosphere. These gases trap heat, leading to the greenhouse effect.
- Aerosol emissions: Burning fossil fuels also emits aerosols that can reflect sunlight and cool the planet, but they can also have indirect effects by influencing cloud formation.
- Land use changes: Deforestation and urbanization alter land surfaces, which can affect regional climate patterns.
- Ozone depletion: Human-produced chemicals can deplete the stratospheric ozone layer, which can allow more ultraviolet radiation to reach Earth's surface, affecting climate.
- Water vapor: Human activities such as irrigation and water management can increase water vapor in the atmosphere, which can contribute to warming.
Feedback Mechanisms:
- Ice-albedo feedback: Melting ice exposes darker surfaces, which absorb more sunlight and further accelerate melting.
- Water vapor feedback: Warmer temperatures increase evaporation, which leads to more water vapor in the atmosphere, trapping more heat.
- Cloud feedback: Changes in cloud cover and type can affect the amount of sunlight and heat reaching Earth's surface.
- Permafrost feedback: Thawing permafrost releases methane, a potent greenhouse gas, contributing to further warming.
Other Factors:
- Earth's orbit: Variations in the shape and tilt of Earth's orbit can influence the amount of solar radiation reaching different parts of the planet.
- Plate tectonics: The movement of Earth's tectonic plates can create or destroy landmasses, which can alter ocean currents and global climate patterns.
