The long-term alteration of temperature and typical weather patterns in a place constitutes a significant environmental shift. This phenomenon is largely attributed to increased levels of atmospheric carbon dioxide produced by the use of fossil fuels. An example is the observable increase in global average temperatures over the past century, coupled with more frequent extreme weather events, impacting human populations and agricultural practices worldwide.
Understanding this planetary transformation is crucial for students studying human geography. It facilitates the analysis of its impact on human societies, migration patterns, resource distribution, and geopolitical landscapes. Examining the historical context reveals that while natural variations have always existed, the current rate and magnitude of change are unprecedented, directly correlating with human activities since the Industrial Revolution. Comprehending this link enables the exploration of sustainable development strategies and mitigation efforts.
