Global Warming
WHAT IS GLOBAL WARMING?
Global warming relates to the increase in the average temperature of the Earth's surface that has been observed in recent years, and it is projected to continue. It is debated as to whether this is a natural occurrence or whether human activity has impacted or accelerated it. This is enhanced by the greenhouse effect, which is induced by emissions of greenhouse gases into the air.
CAUSES 0F GLOBAL WARMING
1. Human Activities
2. Burning of Fossil Fuels
3.Use of Chemical
Fertilizers 4. Industrial
Advancement
5. Deforestation
6. Volcanic
Eruptions
7. Melting of the Glaciers
8. Depletion of Ozone

9. Air Pollution
10. Greenhouse Effect
Effects of Global Warming
1. Increase in temperature
2. Rising sea levels
3.Extinction
4. Effect on plants and animals
5.Effects on human health
6.Storms
7. Droughts
8. Economic collapse
9. Ecosystem Failure
10. War
11.Ozone layer depletion
12. Five main groupings* PEOPLE - Health, Food, Water
use and Costs.
* FRESHWATER – Extreme wet,
extreme dry and Land ice.
* OCEANS – Sea level, Sea ice and
Ocean chemistry.
* ECOSYSTEMS – Lakes and
rivers, Land and Salt water.
* TEMPERATURE – Air, Ocean,
Water and Ground.
1. Reduce the usage
of Appliances 2. Plant trees
3. Avoid use of plastic
bags 4. Choose energy efficient
bulbs
5. Reduce the usage of
fertilizers 6. Turning of Electrical Appliances
7. Consider recycling
if possible 8. Education
Conclusion
Global warming is due to the increased carbon
dioxide and greenhouse gases in air due to
pollution caused by human and it is predicted
that it will cause variety of negative effects.
Thus to reduce the global warming we should
develop some steps for the prevention, we must
avoid unnecessary use of automobiles, plant
plenty of trees & recycle the objects and make
absolute use of non-conventional energy sources.
Apart from that we should organize self-
awareness programmes, plan exhibitions in
different parts of countries to create awareness on
global warming. Also to slow down global
warming, adaptation schemes must be forwarded.
Constructing flood defences, banning buildings
close to sea areas are some of the measures we
can adapt.
Because together,
we can make a difference!
