The science on the Ice Ages is still uncertain. It is clear that they were triggered by some other cause, very likely the Milankovitch cycles, and that carbon dioxide levels only rose gradually over a period of almost a thousand years after the start of the Ice Age periods.
Milankovich cycles can cause a very small reduction in average global temperatures over a period of centuries, but are considered too weak to be the only explanation of the ice ages. Scientists say that as the earth cooled slightly, as a result of a change in the Milankovich cycle, the level of atmospheric water vapour fell, resulting in a gradual further fall in temperatures. Eventually, carbon dioxide concentrations began to fall in tandem with falling water vapour levels and reinforced the global cooling, until an ice age was underway.
A:Absolutely there is a connection. Every start to temperature drop has been during times of high CO2 levels. Every warming period has started during times of known low CO2 periods. We know this to be the case through glacial and holocene data. We have also determined why this occurs. Most of the atmosphere's CO2 is absorbed by open waters. In particular, the open waters of the Northern Ocean. When temperature warm, water is unable to absorb CO2 as quickly as it does when it is cooler. This is why, in all of the earth's history, we have never seen stable CO2 levels. They will always follow the temperature by 10 to 800 years. The Milankovich theory explains the great temperature swings of the past 4 ice ages. These temperature swings have always caused changes far in excess of any other driving force, The current warming trend, which started 10,200 years ago started through this cycle.

How is metabolism part of the carbon cycle?
Metabolism involves ither using energy to build organic molecules or breaking down organic molecules in which energy is stored. Organic molecules contain carbon.Therefore, an organism's metabolism is part of Earth's carbon cycle.
Carbon chains can form branches and cross-links?
Carbon chains can indeed form branches when additional carbon atoms are attached to the main chain. Cross-links occur when the branches of different carbon chains are connected, creating a network structure. These branchings and cross-links can greatly influence the physical and chemical properties of the resulting compound.
Do All fuels produce carbon dioxide when burnt?
Many do, some don'tAn explosion is nothing more than the rapid release of energy. This is most commonly due to the rapid combustion of a material, although nuclear explosions do not involve combustion. The combustion of any hydrocarbon or other carbon-containing substance ALWAYS produces carbon dioxide. This might include explosion due to a natural gas or gasoline. It is possible, however, to explode substances that do not contain carbon, such as pure hydrogen (the very famous Hindenburg disaster in 1937 is a classic example of a very big hydrogen gas explosion -- see the Web Links to the left of this answer for more about that and an impressive video -- skip ahead to 3:30 min to see the explosion!). An explosion of hydrogen produces only water vapor (H2O), NOT carbon dioxide (CO2). SO2, sulfur dioxide, is also commonly ford when sulfur is burned instead of carbon. Azide salts like NaN3 are commonly used to explosively inflate car airbags. On detonation, they decompose to the elemental metal. This is a favourable transition due to a positive change and the formation of highly stable free nitrogen gas.Also, nuclear (both fusion and fission) themselves do not produce carbon dioxide, although they may cause surrounding objects to incinerate, which would release carbon dioxide.See the Web Links to the left of this answer for some impressive videos of different types of explosions, including ones that do and don't produce CO2 emissions!Another product of what is known as incomplete combustion is COCO, or carbon monoxide, can be formed when there is not enough combustion for carbon dioxide, and is extremely poisonous to humans. It is another potential product of an explosion, which is essentially combustion.
What substance is pure carbon?
Pure carbon is one kind of element, which is one kind of pure substance.There are several materials that are formed from pure carbon, including:graphiteDiamond. Diamond is elemental carbon that has been exposed to high pressure and temperature for prolonged periods to form the crystal diamond carbon nanotubes(See the links below for other allotropes of carbon)Anthracite coal is nearly pure carbon.
What links have scientists made between Volcanoes and climate change?
When a volcano erupts, it releases a large amount of ash into the atmosphere which creates a localized greenhouse effect. Additionally, the burning of any local organic matter can cause a lot of carbon dioxide into the air.
What evidence is there to suggest that carbon dioxide produced from burning fossil fuels may be linked to Global Warming?
A:People, that is already a long list that [sadly] is getting longer every day.A:Lots of research shows that man-made (anthropogenic) carbon dioxide (CO2) is directly responsible for Global Warming:rise in carbon dioxide levels since the start of the Industrial Revolution (when humans first started to burn fossil fuels on a large scale). Today's levels are much higher than they ever have been in the past 650,000 years;there is an unequivocal relation between man-made carbon dioxide emissions and the measurements of atmospheric carbon dioxide;the proven fact that increased atmospheric carbon dioxide increases global temperature. Observations clearly show the earth is warming;isotope analyses of atmospheric carbon dioxide allows to trace its man-made origins.exhaustive research rule out other greenhouse gasses and/or natural carbon dioxide sources which might cause the current temperature increases/atmospheric carbon dioxide levels.See links below for addtional information/graphs.I think its because carbon dioxide stores heat and the atmosphere holds the co2 on earth.
What is the link between humans and global warming?
The links are deforestation and fossil fuels. When we cut down forests this means that more carbon dioxide is left in the atmosphere where it warms as a greenhouse gas. When we burn fossil fuels we are releasing extra carbon dioxide emissions that have been hidden away underground for millions of years.

What temperature does sodium citrate decompose at?
The term sodium citrate includes three distinct substances. An MSDS for a form of one of these substances indicates that it decomposes at a temperature above 230oC.Please see the links.
How is metabolism part of the carbon cycle?
Metabolism involves ither using energy to build organic molecules or breaking down organic molecules in which energy is stored. Organic molecules contain carbon.Therefore, an organism's metabolism is part of Earth's carbon cycle.
Why bubbles come when you add vinegar and crushed chalk?
The reaction between Chalk and Vinegar creates carbon dioxide. Chalk is calcium carbonate and when vinegar is poured on it. It is prepared from water and acetic acid it should fizz up as the oxygen in the acetic acid combines with the calcium carbonate. The foams are carbon dioxide that is formed when the oxygen from the acetic acid links with the carbon from the calcium carbonate.
What is the different temperature levels between fahernheit and kelvin?
What is the different temperature level between degrees Fahrenheit and kelvin? Scroll down to related links and look at "Conversion of temperatures and formulas".
Which molecule contributes to the greenhouse effect?
CO2 Methane
What layers must oxygen and carbon dioxide pass through as they exchange between blood in capillaries and the air in the alveoli of the lungs?
Oxygen and carbon dioxide pass across the Alveolar-capillary barrier. This is the barrier that separates the air sac in the lung (the alveoli) from the miniscule blood vessel (the capillary). The barrier is extremely thin - a hundred times thinner than a regular piece of paper. Follow the Related Links below to view a Wikipedia article on this subject.
Does coal pollute?
It releases CO2 into the air (CO2 is carbon dioxide) which destroys the Ozone layer
Which part o the hemoglobin molecule does carbon dioxide attach?
Carbon dioxide primarily binds to the globin part of the hemoglobin molecule, specifically to specific amino acid residues within the globin chains. This binding forms carbaminohemoglobin and plays a role in the transport of carbon dioxide from tissues to the lungs for elimination.
What does plants release into an atmosphere?
A plant takes the carbon dioxide we exhale and turns it into oxygen for us to breath. This is a process called Photosynthesis and takes place only during the day, in the presence of sunlight. Plants also have a respiration cycle - take in oxygen to utilize their stores of energy - and give off carbon dioxide and water. See Related Links.
