Carbon dioxide is causing global warming and climate change. Countries are trying to reduce their emissions of this greenhouse gas. We measure CO2 levels to see if our preventative measures are having any effect.

How do stalactites relate to Earth Science?
By being geological features, formed naturally from the mineral calcite by rain-water and atmospheric carbon-dioxide!
The substance which changes from solid to vapour state at normal atmospheric pressure without being liquified is?
One substance that does that is carbon dioxide.
How do people know that greenhouse gases are being emitted?
Using carbon dioxide as an example: * Measurement of atmospheric carbon dioxide show a progressive increase * Calculations from the amount of fuel consumed indicate that CO2 is being generated, the gas is not being contained, removed or colected. It must therefore be being emitted
How does photosynthesis reduce carbon levels?
Photosynthesis reduces atmospheric carbon dioxide by using it as a reactant in a chemical reaction to create stored energy in autotrophic organisms. This is part of the reason environmental activists are trying to prevent forests being cut down - the forests can help mitigate some of the effects of increased atmospheric carbon dioxide and put a slightly brake on global warming.
What is being reduced that can absorb carbon dioxide?
As more forest is being reduced that can absorb carbon dioxide.
What is the use of carbon dioxide?
used by plants and trees to be turned into oxygen.
Why solid carbon dioxide can never be wet?
At normal atmospheric pressure, carbon dioxide goes directly from the solid phase to the gas phase without ever being a liquid in between. The technical term for this is "sublimation." It is possible to have liquid carbon dioxide at higher pressures, so strictly speaking it's not true to say that solid carbon dioxide can never melt ... it just doesn't happen at normal pressures.
Which reactant of photosynthesis is reduced?
In photosynthesis, the carbon dioxide molecules are being reduced, while the water molecules are being oxidized In photosynthesis, the carbon dioxide molecules are being reduced, while the water molecules are being oxidized
Was carbon dioxide present in earth's early atmosphere?
Yes, carbon dioxide is present at varying concentrations at all levels of the atmosphere. Most of it is in the troposphere, the lowest level. It comprises about 0.04% of atmospheric gases, but this is a dynamic amount as it is constantly being removed and replaced by the processes of the carbon cycle.
Why is more carbon dioxide being produced?
More carbon dioxide is being produced primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming.
What are caverns made of?
Air. A cavern is a void. :-) Most caves are in limestone and formed by the rock's calcium carbonate (its main constituent) being dissolved away by rainwater acidified by absorbed by atmospheric carbon-dioxide.
What incresses carbon dioxide?
When we inhale oxygen and exhale carbon dioxide. Also, it will increase when the plants and trees are being cut down because when this happens, there will be nothing to absorb carbon dioxide. When carbon dioxide continues to increase, global warming will also worsen.
