Why should the amount of carbon in the atmosphere today be reduced?

The present levels of carbon dioxide dioxide in the atmosphere are causing global warming and climate change.


Would a forest fire affect the amount of carbon dioxide in the atmosphere?

Forest fires increase the amount of carbon dioxide in the atmosphere


What is an increase in CO2?

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.


How could massive amount of dust in the atmosphere cause global climate changes?

it could block out the sun and cause the earth to cool


How might gases cause climatic changes?

Greenhouse gases that we are adding to the atmosphere are carbon dioxide and methane (mostly). These gases reduce the amount of thermal energy escaping into space, effectively warming the atmosphere. Too much warming heats the whole globe, global warming, which is causing climate change.


Which increases the amount of carbon dioxide in the atmosphere acting as carbon dioxide?

What does the Fourth Report of the IPCC say about levels of carbon dioxide in the atmosphere?

The Fourth Report of the IPCC (The United Nations' Intergovernmental Panel on Climate Change), Climate Change 2007, said:The amount of carbon dioxide in the atmosphere in 2005 (379 ppm) exceeds by far the natural range of the last 650,000 years (180 to 300 ppm).

What is the amount of atmosphere on Mars?

The atmosphere is very thin and is mostly made up of Carbon Dioxide.


What would a volcano do to atmosphere?

When it erupts, it releases a large amount of carbon dioxide into the atmosphere, polluting it.


What happens when there is great amount of carbon dioxide in the atmosphere?

Carbon dioxide (CO2) is a greenhouse gas which is causing Global Warming. When there is a great amount of it in the atmosphere, then it absorbs a great amount of heat. This makes Global Warming worse.


What could cause climate change?

It is generally accepted that the increasing amount of carbon dioxide in the Earth's atmosphere is the cause of climate change. Many different factors affect the carbon dioxide level, but the burning of fossil fuel (coal, oil, natural gas) seems to be the most important factor.
