What is Climate Change?

Climate change refers to the long-term variations in global climate patterns. These changes can be driven by natural processes, external forces, or human activities. However, the term "global warming" specifically highlights the impact of human activities on the planet's temperature.

The Human Impact

Over the past few decades, human activities have significantly contributed to global warming. The Earth's average temperature has risen by approximately two degrees Celsius, and projections indicate continued warming unless we take action. While thousands share responsibility for this change, several key factors contribute to the problem:

• The Greenhouse Effect: The burning of fossil fuels releases greenhouse gases into the atmosphere,

Warm-up Exercises

Agricultural Societies

Agricultural societies formed larger groups. The agricultural revolution transformed the way resources were obtained through:

• Plant species cultivation
• Hydraulic work (reservoirs, dykes, terraces, canals, and channels)

The impact on the environment was relatively small.

Industrial Societies
