Types of Climate Variation

Climate, although very slowly, keeps evolving. There are many causes behind variation in climate.

Climate variations can be categorized into two broad contexts.

Natural Climate Variation: There are several natural causes that force climate to change across time and scale. It can be further drilled down into the following categories. Natural Forcings of the Climate System The Sun and the Global Energy Balance Radiative Forcing Greenhouse Effect Natural Variability of the Climate Externally and Internally Induced Climate Variability Feedback Global and Hemispherical Variability Regional Variability

Human-induced Climate Variation: Human activities also influence the climate. The major human-induced causes include changes in greenhouse gas (GHG) concentrations, changes in aerosol levels, and changes in land use and land cover. Enhanced Greenhouse Effect

Let us study about these one by one.
