What is Global Warming?
Global Warming is the theory that we as humans are increasing greenhouse gases (the layer of gases that catches the sun’s rays and heats the earth) through industrialization causing more gases and increasing the amount of sunlight that gets caught and heats the Earth.

General Viewpoint
The general viewpoint is that global warming and pollution from CO2 emissions are adding to greenhouse gases so significantly that the Earth is warming up and will continue to warm.

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 feet in only one century! This would mean many heavily populated costal cities would flood causing millions maybe billions of dollars 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 have been found migrating towards the poles due to the increase in heat.

Real Facts
The number of category 4 and 5 hurricanes have 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 are already responding to global warming, moving closer to the poles.

Future Effects of Global Warming
Deaths from global warming will double in just 25 years, to 300,000 people a year.
Global sea levels could rise by more than 20 feet with 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.

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 all the processes we use to make our lives easier are efficient and have very little harm on our environment.
