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 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

Reasons of Temperature Rise
Increase concentration of greenhouse gases
Burning fossil fuelsThe earth
temperature rose 1 degree Fahrenheit since last century

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.
