The Carbon/CO2 on earth is part of a natural cycle which balances the CO2 in the atmosphere with the carbon locked in the rocks as limestones, and hydrocarbons. In general over the totality of geologic time the amount of CO2 in the atmosphere has fallen as a result of biological processes. In recent times human activity has been responsible for releasing a large quantity of fossil Carbon (oil, gas and coal) as CO2 into the atmosphere. While much of this has been buffered by the CO2 dissolving in the oceans, there has also been a marked increase in CO2 % in the atmosphere since the industrial revolution.

By how much have carbon dioxide emissions increased its atmospheric percentage over the past 250 years?
CO2 levels were about 260-280 ppm immediately before industrial emissions began and did not vary much from this level during the preceding 10,000 years. The concentration of carbon dioxide (CO2) in Earth's atmosphere has reached 391 ppm (parts per million) as of October 2012. ((391-260)/391)*100 = 33.50 Thus there has been a 33.5% increase in the levels of CO2 in Earth's atmosphere over the past 250 years.
How do you increase amount of carbon dioxide in greenhouse?
Simplest would be to remove any plants from the greenhouse, then spend some time in there yourself. Plants remove CO2 from the air, while your breathing would introduce CO2 into the air. If you are dead set on keeping your plants in the greenhouse (weird, I know), then most things that burn or decompose will add some form of CO2 to the air. Out of curiousity; why would you want higher levels of CO2?
What is the most likely outcome of the use of fossil fuels is not decreased over the next 50 years?
increase in atmospheric CO2 and increase in surface temperature
What do CO2 and atmospheric CO2 levels and the global temperature from the last 150 years have in common?
They're both increasing, in pretty good correlation with each other. Most of the increase in carbon dioxide is a result of human activities. Additionally, and similarly, much of the observed increase in temperature is a result of humans.
What describes global co2 emissions?
The amount of CO2 released by humans has increased over the last 200 years. This increase is primarily due to using fossil fuels in industries and vehicles.
When blood CO2 levels increase does the pH increase or decrease?
It decreases.
How does increase of CO2 levels affect photosynthesis?
Up to a point, an increase of the reactant Carbon dioxide will increase the production of oxygen (increase the rate of photosynthesis). However, it will eventually change the ratio of CO2 and water as the CO2 increases, and the production of oxygen will decrease, (or in other words, the rate of photosynthesis decreases). This is one of the reasons why an increase of CO2 levels in the atmosphere is dangerous, as oxygen levels will decrease.
Why is the increase of co2 making sea levels rise?
The increase in carbon dioxide (CO2) is warming the planet. The oceans are expanding and the ice caps are melting causing sea levels to rise.
How does the pH in the blood change with an increase in the level of CO2?
An increase in blood CO2 levels will result in an increase in carbonic acid formation, and therefore lower the pH.
What are bodily symptoms of increased CO2 levels?
Increase in confusion, and finally loss of consciousness, coma and death (with high enough CO2 levels).
What specific human activities have lead to atmospheric CO2 levels increase?
Humans are polluting the planet mostly by doing activities that lead to atmospheric CO2 levels increase. The electrical devices like oven, microwave, machines used for warming ourselves do this but cars are the most dangerous because they relase the most CO2.
How has the amount of CO2 in the atmosphere changed over the past few years?
The amount of CO2 in the atmosphere has been increasing steadily over the past few years. This increase is primarily due to human activities, such as burning fossil fuels and deforestation, which release large amounts of CO2 into the atmosphere. The rising levels of CO2 contribute to global warming and climate change.
What are the symptoms of high CO2 levels?
what is considered high levels of co2
Why does an increase of NaOH indicate an increase of CO2?
The reaction is:NaOH + CO2 = Na2CO3An increase of CO2 lead to an increase of NaOH consumed.
How might the global carbon cycle impact Kansas and society?
The global carbon cycle may impact Kansas and society by changing the CO2 levels of the area. When CO2 levels increase, the atmosphere is able to hold more heat.
What are normal co2 levels in the body?
What are normal CO2 levels in the human bod
What is the relationship between increased blood carbon dioxide respiratory rate and depth?
CO2 is the primary cvontrol for rate of breathing (not oxygen as many would expect). High levels of CO2 are very toxid to the tissues of the body and os it was allowed to remain in the blood most of these tissues would die off. And so sensors within the blood systmem detect the CO2 levels and stimulate faster deeper breathing if thesae elvels are to high for safety.
