What is Global Warming?

Global Warming is the theory that we as

humans are increasing greenhouse gases

(the layerof gases that catches the suns

rays and heats the earth) through

industrialization causing more gases and

increasing the amount of sunlight that gets

caught and heats the Earth.


4/14

General Viewpoint

The general viewpoint is that global

warming and pollution from CO2

emissions are adding to greenhousegases so significantly that the Earth is

warming up and will continue to warm.


5/14

Why is this warming bad?!

We believe that this increase in

temperature will eventually cause the

melting of the ice caps. This melting could

increase the oceans height by up to 2 feetin only one century! This would mean

many heavily populated costal cities would

flood causing millions maybe billions ofdollars and damage and the potential loss

of life in these cities.

Other Effects from Global Warming

There are also other effects to global

warming such as natural disasters have

been increasing, disease have been

spreading more rapidly, and animals havebeen found migrating towards the poles

due to the increase in heat.

The surface ocean currently absorbs about one-fourth of

the CO2emitted to the atmosphere from human activities.

Real Facts

The number of category 4 and 5 hurricaneshave almost doubled in the last 30 years.

The flow of ice from glaciers in Greenland has

more than doubled in the past decade.

At least 279 species of plants and animals arealready responding to global warming, movingcloser to the poles.


11/14

Future Effects of Global Warming

Deaths from global warming will double in just25 years, to 300,000 people a year.

Global sea levels could rise by more than 20 feetwith the loss of shelf ice in Greenland and

Antarctica, devastating costal areas worldwide.

Heat waves will be more frequent and intense.

Droughts and wildfires will occur more often.

The Arctic Ocean could be ice free by 2050.More than a million species could be driven to

extinction by 2050.

What We Can Do

Use Wind Energy

Reduce CO2Emission

Action is essentialat every level

Individual

International

Plant & Save trees

Recycle the product

My View

I do strongly agree that with that all the

privileges we are given through industrialization

we need to use our intelligence to make sure allthe processes we use to make our lives easier

are efficient and have very little harm on our

environment.
