Chapter 2 Climatic Regions and Climate Change from the Kerala Social Science 2 Textbook (Standard X) explores the world's diverse climatic regions, their characteristics, and the impact of climate change. Below are comprehensive notes designed for examination preparation, enriched with tables, comparisons, and structured explanations.It includes Aspects like:
Definition of a Climatic Region:
A climatic region is an extensive geographical area with similar climate characteristics, determined by weather elements like temperature, precipitation, and wind.
Key Points:
• The Earth's climate varies significantly across regions, from severe cold with snowfall to extreme heat and aridity, or moderate temperatures with humidity.
• Each climatic region has unique flora, fauna, and human lifestyles adapted to its geographical and climatic features.
• The chapter begins with a personal account of Nikhil Shibu, living in New Brunswick, Canada, highlighting its cold winters and warm summers.
Climate Change
Definition: Climate change is a long-term shift in weather patterns and temperatures caused by human activity or natural variability, affecting ecosystems globally.
Causes of Climate Change
• Natural Causes (uncontrollable):
o Volcanic eruptions (release ash and gases).
o Ocean currents
o Cyclic climate changes (e.g., Ice Ages, interglacial periods).
• Anthropogenic Causes (human-induced):
o Deforestation (reduces carbon sinks).
o Oil mining and fossil fuel burning (increases greenhouse gases).
o Industrialization
o Urbanization and land-use changes.
o Solid waste and industrial effluents.
