Yes, when you cut down a tree and it decomposes or is burned, the carbon stored in the tree is released back into the atmosphere as carbon dioxide. This contributes to the increase of carbon dioxide levels in the atmosphere, a greenhouse gas that contributes to climate change.

Burning one tree can release around 10-15 million BTUs of energy. This energy output can vary depending on the size and type of tree being burned.
Burning wood and coal add carbon dioxide to the atmosphere, where it joins other greenhouse gases to contribute to the greenhouse effect. Burning wood may only release carbon that has been stored for some years, depending on the age of the tree. Burning wood will usually not add to the normal carbon cycle, especially if another tree is growing in its place. Burning coal, however, releases carbon dioxide that has been hidden away underground for millions of years. This extra carbon disrupts the natural carbon cycle and is causing the enhanced, or accelerated greenhouse effect which is causing the present global warming.
The process of a tree burning to form ashes is a chemical change. This is because the chemical composition of the tree is altered as it undergoes combustion, transforming into new substances such as carbon dioxide, water vapor, and ash.

Burning wood can be considered a form of renewable energy, as long as the wood comes from sustainably managed forests, where trees are replanted at a rate that matches or exceeds the amount being cut down for burning. This ensures that the carbon emissions released during burning are balanced by the carbon sequestration of new tree growth.
On average, a mature tree can produce enough oxygen for two people for a year. This can vary depending on the species and size of the tree. Trees absorb carbon dioxide and release oxygen through photosynthesis.
More carbon dioxide is being produced primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and global warming.
A growing tree absorbs carbon dioxide (CO2) from the atmosphere and stores the carbon in its roots, trunk, branches and leaves. It usually takes decades, sometimes hundreds of years before it becomes a fully grown tree. By the end of that time about half its weight is carbon. When the tree is burnt it releases all that hundred years of carbon into the atmosphere in a matter of minutes. If we burn trees quicker than new trees grow to replace them (loss of forest land to agriculture, deforestation, etc.) the amount of CO2 will increase in the atmosphere.
Yes. New substances are formed, mostly carbon dioxide and water, so it's a chemical change.
