Humans continue to burn fossil fuels (coal, oil and natural gas) in industry, travel and to generate electricity. This releases extra carbon from millions of years ago. More and more people all over the world are demanding electrical goods and the chance to buy a car.
They also cut down forests all over the world that used to absorb carbon dioxide from the atmosphere.

What is the trend of carbon dioxide concentrated in the atmosphere?
The trend, unfortunately, is rising. Two hundred years ago carbon dioxide levels were around 280 ppm (parts per million) and had been that way for thousands of years. Now (2014) levels have reached 400 ppm or 0.04%. They have been rising every year since global warming began.
Why has the carbon dioxide level of the atmosphere been rising for more then 150 years?
The increase in atmospheric carbon dioxide levels over the past 150 years is primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release more CO2 than natural sinks can absorb, leading to a build-up of carbon dioxide in the atmosphere.
How does the internal combustion engine contribute to global warming?
The internal combustion engine powers vehicles by burning gasolinegasoline comes from fossil fuel, so this burning emits carbon dioxide (CO2)carbon dioxide is a greenhouse gas that absorbs heat rising from the warmed earthAs this carbon dioxide has been hidden underground for 300 million years, releasing it now ADDS to the CO2 levels in the atmosphere causing global warming.
What caused the increase in carbon dioxide in your atmosphere over the last 150 years?
The primary reason for the increase in carbon dioxide levels in the Earth's atmosphere over the last 150 years is the burning of fossil fuels such as coal, oil, and natural gas. This releases carbon dioxide that had been locked away for millions of years into the atmosphere, leading to a rise in atmospheric CO2 levels and contributing to climate change.
Where did the carbon dioxide and water vapour come from 4.5 billion years ago?

How many years to recycle carbon dioxide?
None. Plants recycle carbon dioxide continuously.
Why is the concentration of carbon dioxide rapidly increasing in the Earths atmosphere?
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.
Why has the carbon dioxide level of the atmosphere been rising for more then 150 years?
The increase in atmospheric carbon dioxide levels over the past 150 years is primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release more CO2 than natural sinks can absorb, leading to a build-up of carbon dioxide in the atmosphere.
Starting billions of years ago algae lowered the levels in the atmosphere?
Carbon Dioxide
Why have carbon dioxide levels in the earth fallen?
Carbon dioxide levels have not fallen. They have been gradually increasing for the past 250 years when man began burning fossil fuels and cutting down trees. Since 1980 CO2 levels have increased more rapidly than ever before.
Why is it harmful to release carbon dioxide in the air?
Carbon dioxide (CO2) is a powerful greenhouse gas which traps heat rising from the surface of the earth. When we add extra CO2 (burning fossil fuel releases CO2 that has been hidden away for millions of years) we are causing global warming and climate change which has the potential for destroying the environment for humans and animals.
How does carbon dioxide affect the planet in a bad way?
Too much carbon dioxide in the atmosphere, as we have now, 400 ppm (parts per million) or 0.04% instead of the regular 280 ppm that we've had for thousands of years, is the cause of global warming. This is very bad for the planet.
How does the internal combustion engine contribute to global warming?
The internal combustion engine powers vehicles by burning gasolinegasoline comes from fossil fuel, so this burning emits carbon dioxide (CO2)carbon dioxide is a greenhouse gas that absorbs heat rising from the warmed earthAs this carbon dioxide has been hidden underground for 300 million years, releasing it now ADDS to the CO2 levels in the atmosphere causing global warming.
What is the major greenhouse gas and when did its abundance in the atmosphere begin to go up?
Carbon Dioxide is the most abundant, and its levels started rising when we stated to seriously burn coal in the Industrial Revolution, around 250 years ago.
In past years were temperature and carbon dioxide usually at the same rate?
Yes, carbon dioxide levels remained at 280 ppm for many thousands of years, together with an even temperature, before the Industrial Revolution.
When you burn vegetation how does it affect carbon dioxide levels in the atmosphere?
Burning vegetation adds to the carbon dioxide levels in the atmosphere. However, that carbon dioxide was recently removed from the air when the plants were growing, so burning vegetation is carbon neutral.Burning fossil fuels (coal, oil and natural gas), of course, releases extra carbon dioxide that has been hidden away for 300 million years.
