Global Warming

By: Arshed Naeem

History About the Earth.The Earth was formed

about 4.5 billion years ago.

At that time the earth contained about 1% oxygen pressure

The plants were developed first about 2.7 billion years ago

The first animal was develop around 600 millions year ago

Earliest human was born about 4.1 million ago

The Population was doubled from 3 billion to 6 billion from the year of 1959 to 1999

Currently the total world’s population is approx. 6,781,000,000 people

What is Global Warming.Global warming is

an increase in the earth's average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect.

What is causing the global warming?Burning Fossil FuelsCutting down treesBurning forestFactories PollutionCoalNatural GasesOil

The Effects of Global WarmingGreenhouse EffectRising Sea LevelsIncrease temperature

Habitat Damage and Species Affected

What is Greenhouse gases?Greenhouse gases is

any of the atmospheric gases that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming of the Earth's surface.

Here is How Greenhouse Works.

Causes of Rise in Sea LevelsThe sea level rises

about 1.8 mm every year in the past century

What you think is happening here?

Rising Sea Levels

Reasons of Temperature Rise

Increase concentration of greenhouse gases

Burning fossil fuelsThe earth

temperature rose 1 degree Fahrenheit since last century

Increase temperature

Increase temperature

Habitat Damage and Species AffectedThe first mammal was extinct directly due to global warming.

If these global warming continues we could lose as much as 10% of all species on the planet by 2050 and 30% of all bird species by 2100.

What Can be done to stop global warming?Many Scientists

agreed that the burning of fossil fuels is causing global warming. There are many solutions and ways to stop the Global Warming.

Many ways to stop global warming.Stop fossil fuelsStop factories

pollutionwhich will cause

lack of oxygenReduce WasteUse Solar Power

energy

Use clean coal and oil

Drive low emission and more fuel efficiency vehicle

Plant Trees

Al GloreAl gore is the VP and

spent many years in researching how we can resolve the global warming situation

He support clean energy legislation that will create millions of jobs and help solve the climate crisis

In conclusionGlobal warming is affecting plants, animals,

humans and the earth. We need to practice how to conserve our use of fossil fuels to minimize carbon dioxide production. This will slow down the effects of global warming.
