How do trees use carbon dioxide?
The method used to answer this question is to analyze the carbon-14 content of tree rings. Remember that all plants, including trees, use carbon dioxide from the air to produce the substances they need to grow. During each growing season, a tree grows a new layer of wood under its bark.
How is carbon-14 produced?
Until humans began above-ground nuclear bomb testing, all the Earth’s carbon-14 was produced by the reaction of nitrogen in the atmosphere with nuclear particles from the sun. The amount of radiation from the sun is pretty constant over the timescale that carbon-14 is a useful measure. Thus, the fraction of carbon-14 formed by this natural process is pretty constant and is used as the basis for carbon-14 dating. The technique is only good for samples that are younger than about 60,000 years, because essentially all of the carbon-14 in a sample will have disappeared in 600 centuries. Fossil fuels are derived from plants that originally contained carbon-14, but the fuels are millions of years old and no longer contain any carbon-14.
Is carbon dioxide soluble in water?
Gases, including carbon dioxide, are less soluble in warm water than in cold water. You may have discovered this by opening a warm can of a carbonated drink and having an experience similar to the one illustrated by the photo in the sidebar. A great deal of carbon dioxide is dissolved in the Earth’s oceans. If the oceans are warming, we would expect that they can hold less carbon dioxide and could release some to the air. How can we tell whether the increase of carbon dioxide is a result of human activities, in particular fossil fuel burning, or gas leaving the ocean?
How much carbon does man emit?
Man currently causes about 8 gigatons of carbon to be injected into the atmosphere, about 4% of the natural annual flux. There are estimates that about half of man’s emissions are taken up by nature.
Does burning fossil fuels increase CO2?
Burning fossil fuels is not increasing atmospheric CO2. Recovery from the Little Ice Age, driven by the sun, is causing the oceans to release CO2. It is temperature driving CO2 release, not the other way around. Just as it has always been.
Does CO2 change at the South Pole?
Changes in CO2 seem muted at the South Pole, and the Barrow station is noisy as well as having a somewhat short record. Effects at the equator appear delayed at the stations closer to the poles. For those reasons, we will use the Mauna Loa record. It seems evident from Figures 2 and 3 that temperature influences CO2. But is it the global land and ocean temperature, or just the sea-surface temperature that is most important? Figure 4 is a plot of global surface temperature and monthly CO2 change:
Is CO2 coming from the ocean?
It is ten times as likely that atmospheric CO2 is coming from natural sources, namely the warming ocean surface, as it is likely that it is coming from anthropogenic sources. The changes in CO2 track ocean surface temperature, not global carbon emissions. Burning fossil fuels is not increasing atmospheric CO2.
Which process produces the most carbon dioxide?
Cement production produces the most amount of carbon dioxide amongst all industrial processes. To create the main ingredient in cement, calcium oxide, limestone is chemically transformed by heating it to very high temperatures.
