What is climate? Climate is the weather condition prevailing in

an area over a long period. OR

A long-term weather pattern that describes a region.

Therefore,

Climate Change is a long-term shift in the statistics of the weather (including it’s averages).IT IS AS A RESULT OF GREEN HOUSE EFFECT

Why is the Climate Changing?

Human activities is the major source of climate change. Some of these activities may include:

fossil fuel combustion.Deforestation.Respiration.Other sources include;Transportation.Decomposition.

Page 5: Climate CHANGE.. What is climate? Climate is the weather condition prevailing in an area over a long period. OR A long-term weather pattern that describes

These human activities results in the emission of four principal greenhouse gases(major cause of global warming); carbon dioxide(CO2), methane (CH4), Dinitrogen I oxide (N2O), and water vapor(H2O).

Page 6: Climate CHANGE.. What is climate? Climate is the weather condition prevailing in an area over a long period. OR A long-term weather pattern that describes

• CARBON DIOXIDE (C02)

It results from;Fossil fuel(oil, coal, gas) used in

transportation, cooling and heating of building, and manufacture of cement

Deforestation, which inhibits the uptake of CO2 by plants.

By natural process such as decay of plant matter.

CO2

Page 8: Climate CHANGE.. What is climate? Climate is the weather condition prevailing in an area over a long period. OR A long-term weather pattern that describes

• METHANE (CH4)

It results from, Natural gases. Decaying organic materials from

landfills.

CH4

DINITROGEN (I) OXIDE

• It results from,Fossil Fuel combustionFertilizer usageNatural processes in the soil also releases

N2O.

effects of CLIMATE CHANGE

Melting of glaciers can cause flooding and soil erosion.

Rising temperature will cause shifts in crop growing seasons which affects food security

Temperature increase will potentially severely increase rates of extinction for many habitats and species.

Page 14: Climate CHANGE.. What is climate? Climate is the weather condition prevailing in an area over a long period. OR A long-term weather pattern that describes

A rise in extreme event will have effects in the health and lives as well as associated environmental and economic impacts.

More precipitation in some areas and not enough in others

Possible Solutions to CLIMATE CHANGE

ReforestationSequestration of CO2( forming stable chemical

bond between CO2 and other agents) e.g. by pumping CO2 into the ground.

Use renewable energy sources like Sun, wind.Reduction of global dependence on fossil fuel

by providing other alternative means

Such as ;

Page 16: Climate CHANGE.. What is climate? Climate is the weather condition prevailing in an area over a long period. OR A long-term weather pattern that describes

biofuel(fuels produced from organic matter such as starch, wheat, and animal fat).

Walk and bicycle more.
