This means an increase in the amount of carbon dioxide (CO2) in the atmosphere.
There is a normal balance of carbon dioxide in the atmosphere. Trees and green plants soak it up, and then when the trees rot or are burnt the carbon dioxide goes back into the atmosphere.
However, more than 200 years ago we began seriously burning coal and oil. This released carbon dioxide that had been trapped millions of years ago. So over the years the amount of this gas in the atmosphere has been increasing. Most climate scientists agree that this increase in carbon dioxide is contributing to climate change and global warming.

What environmental problem is caused by excess carbon dioxide in the atmosphere?
None that can be proven. While global warming effects an increase in atmospheric CO2, it is not correct to assume that an increase in CO2 will cause global warming; there are several other atmospheric gasses more warming than CO2, also on the rise.
Why do CO2 levels increase over time?
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.
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 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.
Why photosynthesis rate is higher at sea level than that at high mountains?
The partial pressure of CO2 in air decreases with the increase in altitude. Therefore, increase in molar concentration of CO2 is smaller at higher altitudes than at lower altitudes for increases in molar fraction of CO2. This study aimed to predict the effect of global CO2 increase on net photosynthetic rate of spring wheat (Triticum aestivum L.) at high altitudes. The net photosynthetic rate of spring wheat grown in Lhasa (3688 m above sea level), China, was compared with that of the same cultivar grown in Sapporo (15 m above sea level), Japan. At the current level of CO2, it was signifi cantly lower in Lhasa than in Sapporo, and stomatal conductance, chlorophyll content (SPAD value) and apparent quantum yield were similar in both locations. The interaction of CO2 level and altitude was suggested; the amount of increase in net photosynthetic rate caused by increase in CO2 was smaller at high altitudes than at low altitudes. Lower CO2 partial pressure at higher altitude could explain the difference in net photosynthetic rate between altitudes, and the interaction of CO2 level and altitude.
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.
Does increase in CO2 increase or decrease respiratory rate?
CO2 WILL increase your respiratory rate as you are needing to breathe in more air (oxygen) to breathe.
What effect would an increase in co2 have on respiratory rate?
respiration rate would increase in order to blow off co2
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.
Why is CO2 increase and what are the effects?
bavt
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.
When blood CO2 levels increase does the pH increase or decrease?
It decreases.
How do people increase CO2 in the air?
by breathing out
The primary drive to breathe is?
Increase of CO2
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.
If more fossil fuels are burned you could expect an increase in what?
increase in CO2 and diminishing of Ozone layer
What is the increase of co2 causing?
The increase of carbon dioxide in the atmosphere is causing global warming and climate change.
