The major cause of the change in levels is the burning of fossil fuels (coal, oil and natural gas). This releases extra carbon dioxide that has been hidden underground for millions of years, and it is this extra CO2 that is causing global warming.
The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.
In the mid-1700s the levels of carbon dioxide in the atmosphere were about 280 ppm (parts per million).In 2004 the levels of carbon dioxide in the atmosphere were about 375 ppm.In 2012 the levels of carbon dioxide in the atmosphere were about 393 ppm.

Yes. Carbon dioxide is a greenhouse gas. If levels of it in the atmosphere are higher than normal, then they trap more heat. This is causing global warming, and the world warming is causing changes in climate.
The atmospheric temperature will decrease

The carbon Dioxide levels in the Earth's atmosphere are rising.

Not burning carbon compounds.
Plants use carbon dioxide, so there is less carbon dioxide in the atmosphere in the summer.

If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.
Levels of carbon dioxide are changing in the atmosphere because of the burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity. This year (2013) carbon dioxide levels in the atmosphere reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
Earth, Mars and venus all have nitrogen and Carbon dioxide in their atmosphere, though the levels vary from planet to planet.

Yes. Carbon dioxide is a greenhouse gas. If levels of it in the atmosphere are higher than normal, then they trap more heat. This is causing global warming, and the world warming is causing changes in climate.
