Because of increased use of fossil fuels. Burning fossil fuels for transport and to generate electricity releases carbon dioxide that has been out of the loop, buried underground for millions of years. That is why it's such a problem for the carbon cycle, which can't move it all out of the atmosphere.
That and the fact we cut down all the great forests, which used to store carbon (half a tree's weight is carbon). So that's why there is an extra amount of CO2 in the atmosphere.
What else can I help you with?
Does respiration decrease or increase the amount of carbon dioxide in the atmosphere?
Respiration (breathing) has no effect on the amount of carbon dioxide in the atmosphere. Breathing is part of the carbon cycle. We take in carbon in our food and drink and we release it again when we breathe. If we eat too much, the extra carbon is stored in our bodies, making us fatter, in much the same way as a tree stores carbon in its wood as it grows.So breathing does not increase or decrease the amount of carbon dioxide in the atmosphere.
How does respiration affect the amount of carbon dioxide in the atmosphere?
Respiration, breathing, has no effect on the amount of carbon dioxide in the atmosphere. This is part of the natural carbon cycle. Burning fossil fuels (coal, oil and natural gas) releases carbon dioxide that has been hidden away for millions of years. This extra gas is increasing in the atmosphere.
What human activities release extra carbon dioxide into the atmosphere?
hair spray
What happen when extra carbon dioxide builds up in the atmosphere?
nothing will happen at all
In which carbon pool does most of this extra carbon accumulate?
Most of the extra carbon from human activities accumulates in the atmosphere as carbon dioxide, contributing to the greenhouse effect and climate change.
How does the main kind of organism that brings about decay let carbon dioxide into the atmosphere?
the organism releases carbon dioxide as a waste, as an extra from creating energy it can use.
Does the greenhouse effect increase carbon dioxide in the atmosphere?
No. The greenhouse effect keeps the earth warm. Extra carbon dioxide added to it is causing global warming.
How is climate change a problem for the carbon cycle?
Climate change affects the carbon cycle by increasing the concentration of carbon dioxide in the atmosphere, which in turn intensifies the greenhouse effect and leads to global warming. This disrupts the balance of carbon being stored in the atmosphere, oceans, and terrestrial systems, impacting the capacity of these reservoirs to absorb and store carbon effectively. This can lead to feedback loops that exacerbate climate change.
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.
What ways have you added excess carbon dioxide to the atmosphere?
Excess, or additional carbon dioxide is added to the atmosphere only by the burning of fossil fuels (coal, oil and natural gas), and a very small amount from volcanic activity.All other carbon dioxide moves in and out of the oceans, atmosphere and land as part of the normal carbon cycle, which includes the growing and dying of vegetation.Fossil fuels release carbon dioxide that was taken out of the atmosphere (when the vegetation grew) 300 million years ago, so it is extra.
Scientists who are concerned about increased carbon dioxide in the atmosphere believe global warming is caused by?
... the burning of fossil fuels, which is adding extra carbon dioxide to the greenhouse gases in the atmosphere.
What is soil carbon sequestration?
Soil carbon sequestration is a process that is being used to try to to 'store' all the extra carbon that is being released into the atmosphere. There are lots of different ideas about how to do it. One way they are trying to do is by turning biomass into charcoal (which retains the CO2). The charcoal is then plowed into agricultural soil, burying the carbon dioxide.
