Although many very smart astronomers have gone back and forth about this question, it is now generally believed that the rate of expansion of the universe in increasing, that is, it's expanding faster over time.
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.
1 percent of the earths atmosphere is made of the following: - Argon (0.93%) - Carbon dioxide (0.03%) - Neon> trace - Helium> trace - Methane> trace - Krypton> trace - Xenon> trace - Hydrogen> trace - Ozone> trace 21% of earths atmosphere is made of oxygen 78% of earths atmosphere is made of nitrogen
Carbon dioxide (CO2) makes up about 0.04% of Earth's atmosphere. While it is a relatively small percentage, CO2 plays a significant role in the Earth's climate system.
The term for an abnormally rapid rise in Earth's average temperature caused by excess carbon dioxide in the atmosphere is global warming.
The majority of Earth's carbon dioxide is found in the troposphere, which is the lowest layer of the atmosphere where weather occurs. This layer extends from the Earth's surface up to about 10-15 kilometers in altitude.
The Industrial Revolution began increasing the levels of carbon dioxide in the atmosphere when we started burning fossil fuel.
In the atmosphere, in the form of carbon dioxide
This gas was carbon dioxide.
Carbon dioxide
Upper Part
Earths atmosphere is 78% nitrogen,21%oxygen,0.9% argon,and 0.03% carbon dioxide with very small percentages of other elements
carbon dioxide, sulphur dioxide and still nitrogen
the earth atmosphere is made up of carbon dioxide and oxygen and some helium.
Carbon dioxide is a greenhouse gas. More of it in the earth's atmosphere means that more heat will be retained. This will, indeed is, causing global warming.
Carbon dioxide used to make up most of Earth's early atmosphere.
In the past 50 to 100 years, man has burned about one halve of all the oil which formed through the ages, plus large amounts of coal, lumber, and natural gas. This is the source of the carbon dioxide. It would be worse except the oceans absorbed some of the carbon dioxide increase.
the earths atmosphere is 77% nitrogen, 21% oxygen, with traces of argon, carbon dioxide and water.
