CONTENTS

Global warming is the increase in average temperature of the oceans and atmosphere, both observed and predicted.

INTRODUCTION

Naturally occurring greenhouse gases have a mean warming effect of about 33 °C (59 °F).

Water vapor 36–70 %

Carbon dioxide 9–26 %

Methane 4–9 %

Ozone 3–7 %

Clouds

GREEN HOUSE EFFECTS

Natural Causes

• Beyond our Limit

Man-made Causes

• As Much As Possible

MAJOR CAUSES

Methane gas

Sunspots

Arctic Tundra

Water Vapor

Permafrost

NATURAL CAUSES

Pollution

Automobiles

Deforestation

Fertilizer Use

Burning of Fossil Fuels

MAN-MADE CAUSES

Increased in Sea Level

Melting of Glaciers

Changed in Climate

Long summers

Effects on plants and Animals

Skin Cancer

Asthma

EFFECTS

The ozone layer or ozone shield refers to a region of Earth's stratosphere

It absorbs most of the sun's UV radiation hence work as a Protective Shield

Diseases of Skin

Plants will be Damage

Life cycle will be disturbed

OZONE LAYER

Hottest year was 2010 

$100 billion of damage was caused by hurricanes hitting the U.S. coast in 2005 alone.

It is also projected that 15-37% of all plant and animal species could be wiped out by global warming by the year 2050.

STATISTICAL FACTS

Up to 300,000 people a year will die –partly from the spread of tropical diseases.

The average global air temperature rose between 0.5 and 0.74 degrees C during the past century.

An average 2 degree C warming is predicted by 2100.

STATISTICAL FACTS

Threats to Global Economies

Natural Disasters

Animal Habitats

Certain Species extinction

Earth Dries Up and Increase in Deserts areas

Shortage of food

FUTURE WORRIES

CNG and hydrogen operated vehicles should be used.

More no. of trees should be planted.

Chimneys in the Industries should be upgraded so that most of the effluents should get filtered down there.

Climate Policy

Personal Action

HOW TO OVERCOME PROBLEM?

Global warming is caused by natural and anthropological activities

Realize it as Global threat

Collective Efforts are needed

Big economies have to contribute for the most part
