The earth's natural cycle of temperature change takes place over thousands of years. We are still emerging from the last Ice Age which occurred about 22,000 years ago.
The recent increases in carbon dioxide emissions has resulted in the earth warming up much faster than before, since we began burning fossil fuels in the Industrial Revolution, a mere 250 years ago. The ten hottest years on record have all taken place during the past twelve years.

It raises the temperature and makes it hotter through the greenhouse effect.
"Carbon dioxide is released to the atmosphere by a variety of natural sources, and over 95% of total CO2 emissions would occur even if humans were not present on Earth. For example, the natural decay of organic material in forests and grasslands, such as dead trees, results in the release of about 220 gigatonnes of carbon dioxide every year. This carbon dioxide alone is over 8 times the amount emitted by humans. These natural sources are balanced by natural sinks, which remove carbon dioxide from the atmosphere.The increase in carbon dioxide concentration arises because the increase from human activity is not balanced by a corresponding sink."
From 1934 until 2010, the last year we have complete data on, the planet has seen less than 0.2 degrees (C) of actual warming despite man's 80 times increase in carbon dioxide emissions. This is partially due to the small amount of overall emissions that man is compared to the rest of the planets natural emissions.
According to U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2004, 1 therm of natural gas burnt produces 11.7 lbs. of carbon dioxide emissions. Therefore, the Carbon Coefficient for natural gas is: 117 pounds of CO2 per million BTU, or 0.12 pounds per cubic foot of gas.
Natural gas is a fossil fuel. When it is burnt it releases carbon dioxide emissions that are building up in the atmosphere and causing global warming. This is bad for our environment in many ways.
It raises the temperature and makes it hotter through the greenhouse effect.

Coal is the largest contributor to the human-made increase of CO2 in the air. In terms of carbon dioxide emissions, coal is slightly ahead of petroleum and about double that of natural gas.
Hydroelectricity is better because it releases no carbon dioxide emissions to cause global warming. Natural gas is the cleanest of the fossil fuels (coal, oil and natural gas), but it is still responsible for carbon dioxide (CO2) emissions.
Coal has more carbon dioxide emissions than either oil or natural gas.

No, the natural cycle of carbon dioxide (CO2) moves through the land, oceans and atmosphere, and has done for millions of years. It is able to remove all the natural carbon in the air (and part of the global warming carbon as well). It is the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity that releases carbon that has been hidden underground for millennia that is increasing the carbon concentrations in the atmosphere.

Yes, global warming is caused by carbon dioxide emissions from vehicles, but also by deforestation and the burning of fossil fuels (coal, oil and natural gas) in industry, and the generation of electricity, which all releases carbon dioxide.
The burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2). Carbon dioxide is a greenhouse gas which absorbs warmth given off from the earth. An increase of burned fuels means that more and more CO2 builds up in the atmosphere, the Earth's temperature is rising.
