•Climate change is an enormous challenge facing humankind today.
2
•Undoubtedly,it is the single largest environmental threat facing the planet,and we need to act fast to mitigate it.
3
•There is much that need to be done and much that can be done to halt the catastrophic impacts of cliamte change.
Introduction
• The Climate of a given place is the
average weather experienced in that place over a perios of time.
Climate is the average weather of a region or area over a period of time.(35 years).
Various elements of climate such as rainfall,•temperature•humidity•Air pressure•winds•clouds and•sunshine
What is Climate.
What is Climate Change.
Climate Change is natural phenomenon and has been occurring since the earth came into being.
Climate change is a change in the average weather of a given area or region.
This includes temperature,wind patterns, and precipitation. This change is referred to in a global sense and concerns the earth as a whole.
The Earth's Climate in the Past
