This module explains the impacts of climate change on water resources and its implications to disasters. It explores the ways and means of adaptation to the climate change challenges on disaster management.
At the end of this Module you should be able to:
Understand climate change impacts, the underlying risks and resultant challenges to water related disasters; and
2. Apply the knowledge gained in building the resilience of the communities against hydro-climatic disasters.
According to the World Meteorological Organisation (WMO) climate is a natural resource vital to human well-being, health and prosperity. It can be defined as the average weather situation at a specific place measured during a long time period (30 years or more).
Decision-makers use climate information to plan and adapt activities and projects to likely conditions.
People’s lives and livelihoods everywhere are affected by climate. The raising of atmospheric temperature, (also commonly known as global warming), poses a threat to society in a number of ways. A higher number of and longer droughts threatenmillions of people directly.
The term El Niño, (Spanish word for "the Christ-child"), refers to periodic building up of a large pool of unusually warm waters in large parts of the eastern and central equatorial Pacific Ocean.
Takes place at varying degrees of magnitudes and periods.
A number of climate variations(fluctuations) take place without affecting the overall average. For example, in a place, we may have a wetter than normal year followed by a drier than normal year but the average stays nearly the same
Climate Change : Refers to a p ermanent shift in the traditional space-time patterns of climate , e.g. change from one climate mode to another climate mode, which is outside the normal range of natural climate variability, regardless of the causes.
What is climate change?
Why “Global Warming” is the Inappropriate Term
Climate change refers to the general shifts in climate, including temperature, precipitation, winds, and other factors.
Global warming (as well as global cooling) refers specifically to any change in the global average surface temperature.
Global warming is often misunderstood to imply that the world will warm uniformly.
An increase in the average global temperature will also cause the circulation of the atmosphere to change, resulting in some areas of the world warming more and other places less. Some areas can even be cooler.
‘ Global warming' is still often used by media and others to describe climate change.
