Can carbon dioxide come from wood burning furnaces?
Yes, however, wood can be carbon neutral.The process of burning wood also does not emit any additional carbon dioxide than the natural biodegradation of the wood if it were left to rot on the forest floor. Over the course of a tree's life it absorbs carbon dioxide from the atmosphere and then releases this carbon dioxide when it either decomposes naturally or is burned. For this reason, no extra CO2 is added to the atmosphere, it simply releases the carbon dioxide that was previously accumulated back into the environment. Wood is a very environmentally friendly source of fuel because it is carbon neutral. Fossil fuels on the other hand, are not carbon neutral.
How do the lack of trees contribute to global warming?
Trees help to reduce global warming by 'cleaning the air'. Here's how: * A gas that helps to cause global warming is carbon dioxide. * Trees 'breathe' just like we do except when they breathe they take in carbon dioxide not oxygen. * When a tree breathes out it breathes out oxygen. * This is then breathed in by a human. * Carbon dioxide is breathed out the the human... * ...and breathed in by the tree... * This carries on continuously. Some trees have been growing in tropical rainforests like the Amazon Basin for hundreds of years. They store almost half their weight in carbon. So trees help reduce global warming in a way, but with people producing so much extra carbon dioxide global warming is happening. Trees probably have other effects on the environment and global warming, but I only know what is above. Hope it helps :) Yes, living trees breathe in carbon dioxide. But when they die, they ROT, and when they rot, all the carbon they stored over the years will be oxidized and released into the atmosphere as carbon dioxide. Well, not ALL of the carbon. Some part of it will be transferred to the soil. But in places like the Amazon Rain Forest, the soil is too thin to hold much carbon, so very little goes into the soil and what little does is rapidly released into the atmosphere as carbon dioxide. On the other hand, if, instead of allowing trees to die and rot, we were to HARVEST the trees, turn them into lumber, and treat them to prevent rot, the carbon therein would be sequestered (prevented from oxidizing into the carbon dioxide in the atmosphere) almost indefinitely.
How is photosynthesis related to atmospheric carbon dioxide concentrations and climate change?
Photosynthesis is when trees and plants remove carbon dioxide from the atmosphere. The carbon is separated and becomes part of the tree, and the oxygen is released. So a growing tree will store carbon all the time it is growing. More than half the weight of a tree is carbon. So photosynthesis by trees plays an important part in the Earth's carbon cycle.Deforestation, the removal of forests, has been happening all over the world. When trees rot, or are burnt, they release the carbon (as carbon dioxide), and, of course, are no longer able to take carbon dioxide from the atmosphere. The carbon cycle is then disrupted, and more carbon dioxide, a greenhouse gas, builds up in the air. This (together with the burning of fossil fuels (coal, oil and natural gas)) is causing global warming and climate change.
What are greenhouse gases and where do they come from?
Greenhouse gases are gases which trap infrared radiation from clouds and from the warm earth. Examples are carbon dioxide, and methane. Carbon dioxide occurs naturally through the carbon cycle but it is also now being added by burning fossil fuels and from deforestation, where trees no longer absorb and store the carbon. Methane comes from melting swamps, tundra and lakes, as well as from cattle farming.
Which Gas is released when branches of trees are decayed or cut?
When plant life decays, it releases carbon dioxide. This does not occur when trees (or their branches) are simply cut. In fact, if the wood can be preserved so that it does not rot, the carbon contained therein will be sequestered indefinitely.
Do cactus produce carbon dioxide and take oxygen?
Plants take in Carbon Dioxide and put out Oxygen until they die. When they rot, they create CO2.
How does saving energy reduce carbon dioxide emmisions?
Almost all fuel used to create energy (coal, oil, gas) causes carbon dioxide emissions, therefore not using aka saving energy will reduce carbon dioxide emissions. Nature produces most of the carbon dioxide. Man produces about 6% of all CO2 produced. Much of this by items that would otherwise rot and create CO2 naturally.
Why does soda burn your tongue?
It fizzes the same in your mouth as in a glass. The carbon dioxide was dissolved in the liquid due to pressure. But when you depressureize the container when you open the bottle or can, the carbon dioxide "undissolves" and escapes from the liquid. This is what is happening in a glass or container, as well as in your mouth.
How much carbon dioxide is released when vegetable oil is burnt as fuel?
You would probably need to know what type of vegetable oil and what quantity. However, from a global warming point of view, it does not matter because burning a renewable resource like vegetable oil does not make a nett addition to global carbon dioxide concentrations. Vegetable oil is produced by growing a crop, which absorbs carbon dioxide from the atmosphere. After harvesting the crop, we can consume it, burn it or simply let it rot on the ground. This is known as the natural carbon cycle, in which carbon dioxide is absorbed from the air and then eventually returned to the air, with no chnage in long-term carbon dioxide levels. This differs from burning fossil fuels which do actually add to atmospheric carbon dioxide concentrations.

What are at least three possible effects of people continuously cutting down trees?
The trees (or part of them) are burnt or rot, releasing Carbon dioxide (CO2), a powerful greenhouse gas.Trees that rot anaerobically (without oxygen) release methane (CH4), a greenhouse gas 21 times more powerful than carbon dioxide.The trees no longer remove carbon dioxide from the atmosphere (by photosynthesis), so levels of carbon dioxide build up in the atmosphere. This is contributing to global warming and climate change.Animals and birds lose their habitats. This is particularly serious for animals like pandas and koalas that have a special diet.
How is deforestation adding to the greenhouse effect?
Trees remove carbon dioxide (CO2), a greenhouse gas, from the atmosphere and store the carbon in their trunks and branches. When deforestation happens and the trees are burnt or rot, that carbon dioxide is added to the atmosphere, and because no more trees are planted, there is no longer anything to remove the CO2. This is how deforestation adds to the greenhouse effect.
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 can deforestation intensify the greenhouse effect?
Trees store carbon dioxide. When they get cut down they realease this gas. It contributes to greenhouse gases. now that there is so much carbon dioxide in the atmosphere they are letting it offeven if they are not cut down. also scientists have found that over rainforests that clouds are forming higher letting little rain reaching rainforests drying them up. soon they will all be gone! The answer above is very, very wrong. Yes, trees store carbon dioxide. However, when they are cut, this carbon dioxide is not released. On the contrary, it is permanently [b]sequestered[/b] in the wood and wood products made from that tree. (Next time, do some research before you delete information provided by someone who knows what he is talking about.) On the other hand, if we didn't cut them down, then they would eventually die. And when the die, they will rot. And When they rot, they will release that carbon dioxide. Moreover, once they are cut, if the acreage is replanted with seedlings, those seedlings will grow much faster, and store more carbon dioxide per year, than the older trees that were cut down. The one thing that should be avoided, however, is burning trees. Like rotting, this releases carbon dioxide into the atmosphere, only very suddenly, rather than gradually as with rotting.
