Winds, ocean currents, and other mechanisms distribute this energy globally, influencing the climatic conditions of different regions. Long-term and short-term changes in solar intensity can impact global climate.
Volcanic Eruption: Volcanic eruptions with emissions exceeding 100,000 tons of SO2 in the stratosphere are known to affect Earth’s climate. Such eruptions, occurring several times a century, have a cooling effect on the Earth’s atmosphere for several years, partly blocking the transmission of solar radiation to the Earth’s surface.
Orbital Variations: Even slight changes in Earth’s orbit lead to modifications in the seasonal distribution of sunlight received on its surface. Three types of orbital changes—variations in Earth’s eccentricity, precession of the Earth’s axis, and shifts in the tilt angle of the Earth’s axis of rotation—combine to create Milankovitch cycles that exert a significant influence on climate.
Plate Tectonics: The movement of tectonic plates reshapes Earth’s land and oceans over millions of years, generating topographical changes that, in turn, influence global climatic conditions.
Climate conditions are deteriorating with each passing day. While we cannot control the adverse impact on climate caused by the natural factors discussed above, we can take measures to mitigate human influences that have significantly altered the climate in recent times. Human activities leading to air, land, and water pollution, ultimately affecting the climate negatively, must be restrained. Each of us must contribute to controlling this global issue by adopting sustainable practices, reducing carbon emissions, and prioritizing environmental conservation. By collectively addressing this challenge, we can work toward a sustainable future for our planet and all its inhabitants.
