1. Introduction The Earth receives energy from the Sun in the form of sunlight. This solar energy warms the planet’s surface and supports life on Earth. However, not all of the heat absorbed by the Earth escapes back into space. A portion of this heat is trapped in the atmosphere by certain gases, creating a…
1. Introduction The Earth’s climate system is influenced by many natural and human-related factors. Over the past century, scientists have observed a steady increase in the average temperature of the planet. This rise in temperature is commonly referred to as Global Warming. Global warming occurs when certain gases accumulate in the atmosphere and trap heat…
1. Introduction Climate change refers to long-term changes in the average temperature, rainfall patterns, wind systems, and other aspects of Earth’s climate system. These changes may occur gradually over decades or centuries and can significantly affect natural ecosystems, agriculture, water resources, and human societies. The climate of our planet has always undergone natural variations. However,…
