Some scientist's have been concerned since 1896 about what might happen if there were 5.5 billion tons carbon dioxide in our atmosphere. In 1961 a
British scientist did an experiment showing that the carbon in the air was absorbing some of the sun's radiation. Afterward a Swedish scientist, Suante
Arrhenius, found out if the radiation of the sun was trapped in the carbon dioxide the temperature of the earth would increase by 1-2 degrees. In 1988
James Hanson, a respected scientist, told the U.S. Congress "the greenhouse effect is occurring now and it's changing global climate."(1989 Koral). After the 1900's people started making factories and started using fossil fuels like coal, oil, and aluminum. It was the industrial revolution and overpopulation of humans that was the cause of the environmental problems that we have today.
The reason our Earth is getting hotter is that human activities are emitting too much carbon dioxide into the atmosphere. The radiation from the sun gets trapped in the bag of carbon dioxide that surrounds our earth.
One main reason for the problem of global warming is the burning of fossil fuels. Fossil fuels are coal, oil and natural gases. We use these fuels to run factories, power plants, cars, trucks, buses, air conditioning and etc.
The people of the earth are putting 5.5 billion tons of carbon, in the form of carbon dioxide in the air every year! Seventy five percent of this is fossil fuels.For many years, scientists have been predicting that our disregard for
Mother Nature would make the climatic temperature of this Earth to increase greatly. There have been arguments that the whole idea of Global Warming is a hoax, that the temperature cycle is just experiencing an upward trend and will eventually come back
