climate change, its impact and the causes

1. CLIMATE CHANGE
PRESENTED BY OBEY MADUNA

2. THE CLIMATE
CHANGE
MEANS THE DIFFERENCE IN THE
EARTH'S GLOBAL CLIMATE OR IN
REGIONAL CLIMATES OVER TIME. IT
DESCRIBES CHANGES IN THE STATE
OF THE ATMOSPHERE OVER TIME
SCALES RANGING FROM DECADES TO
MILLIONS OF YEARS.(NASA, 2014)

3. THE CLIMATE SYSTEM
CLIMATE SYSTEM IS GOVERNED BY NUMEROUS
INTERACTION BETWEEN CLOSED LOOP SYSTEM. CHANGE
IN THESE SYSTEM, SUCH AS CARBON CYCLE CAN
INFLUENCE THE OVERALL CLIMATE AND LEAD TO
CHANGE.(RICHER DER FORGES,2009)
WEATHER: REFERS TO THE CHANGE TAKING PLACE IN THE
ATMOSPHERE AT PRESENT SHORT PERIOD OF TIME.
CLIMATE: IS THE LONG-TERM PATTERN OF WEATHER IN A
PARTICULAR AREA
THE CLIMATE SYSTEM US MADE UP OF GLOBAL, HEAT
TRANSFER AND WATER CLIMATE SYSTEM.

4. THE GLOBAL
CLIMATE SYSTEM.
IT IS DRIVEN BY A CLOSE
INTERACTION BETWEEN THE
ATMOSPHERE, THE GEOSPHERE(
LITHOSPHERE, HYDROSPHERE AND
SPACE)
HUMAN ACTIVITIES CAN MODIFY
THESE INTERACTIONS, THROUGH:
DEFORESTATIONS
THROWING WASTES
AIR POLLUTION ETC.

5. THE GLOBAL
WATER CYCLE.
THE WATER CYCLE PLAYS AN IMPORTANT ROLE IN
REGULATING THE EARTH CLIMATE
.VICE VERSA, CHANGE IN THE CLIMATE SYSTEM
WILL SIGNIFICANTLY INFLUENCE AND MODIFY THE
WATER CYCLE AND HOW WATER IS DISTRIBUTED
ON THE PLANET
. THE TRANSPORT OF ATMOSPHERIC MOISTURE
FROM THE OCEAN WHICH COVER MORE THAN
TWO-THIRDS OF THE GLOBE, TO THE CONTINENT
PLAYS A VITAL ROLE TO BALANCE THE DISCHARGE
FROM THE RIVER AND GROUNDWATER TO THE
OCEAN
.WATER VAPOR IS THE MOST IMPORTANT OF THE
GREENHOUSE GASES, IN TERMS OF ITS INFLUENCE
IN THE CLIMATE.

6. BY CHANGING THE WATER CYCLE WE
ARE ALSO IMPACTING GLOBAL SEA
LEVEL. THE MAIN. THE MAIN CAUSE OF
THE SEA LEVEL RISES DUE TO THE
THERMAL EXPANSION OF THE WATER
BODY AS TEMPERATURE RISES.
THE SECOND MAIN CAUSES OF GLOBAL
SEA LEVEL RISE IS THE ICE MELT FROM
THE LAND ICE.
THERE ARE ALSO SEASONAL VARIATION
IN THE SEA LEVEL AND DURING STORM
EVENTS AS A RESULT OF CHANGE IN
ATMOSPHERIC PRESSURE.
