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.
The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
Any increase in atmospheric carbon dioxide contributes to global climate change.
Humans burning coal, oil and natural gas increases atmospheric CO2.Deforestation, cutting down trees, means that less carbon dioxide is removed from the atmosphere.Volcanic eruptions can put carbon dioxide into the atmosphere, but not nearly as much as fossil fuels.
The present level of atmospheric carbon dioxide is approximately 380 parts per million and rising rapidly due to human activities such as burning fossil fuels, deforestation and cement manufacture. Until the beginning of the Industrial Age, the long term average concentration of carbon dioxide was in the range 260 to 280 ppm, falling to around 160 ppm during cold periods, but never as high as the present level during all human history.

Human activities have increased atmospheric carbon dioxide levels primarily through the burning of fossil fuels for energy, deforestation, and industrial processes.
Carbondioxde in atmospheric air amount to about 0.04%.
Carbon dioxide (CO2) has increased significantly in the atmosphere since the beginning of the industrial revolution due to human activities such as burning fossil fuels and deforestation. This increase in CO2 concentration is a major contributor to global warming and climate change.

The ocean absorbs large amounts of atmospheric carbon dioxide, and is acidified thereby.
The relationship between the rise of ocean temperatures and the rise in the level of atmospheric carbon dioxide is that when there is a rise in atmospheric carbon dioxide the warmer the temperature of the ocean is
