Climate change refers to long-term alterations in Earth’s climate patterns, particularly an increase in global temperatures over the past century and the impact of human activities on the Earth’s climate system. It is one of the most critical environmental challenges facing humanity and the planet today. Here’s an overview of climate change:

Greenhouse Effect: The Earth’s atmosphere contains greenhouse gases, such as carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor, which trap heat from the sun, preventing it from escaping into space. This natural greenhouse effect keeps the planet warm enough to support life.

Enhanced Greenhouse Effect: Human activities, particularly the burning of fossil fuels (coal, oil, and natural gas), deforestation, and industrial processes, have significantly increased the concentration of greenhouse gases in the atmosphere. This enhanced greenhouse effect intensifies the trapping of heat, leading to global warming and climate change.

Global Warming: The steady increase in average global temperatures is known as global warming. Scientists have observed a rise in global temperatures over the past century, with the most significant warming occurring in the last few decades.
