Human carbon emissions can be offset by controlled burns.

It is possible to fix or increase carbon in the soils of temperate forests, savannas, and grassland through controlled burns.

A new method of manipulating the world's natural carbon capture and storage capacity can help maintain natural processes, according to a study published in 'Nature Geoscience'.

"The use of controlled burns in forests to mitigate the severity of future fires is a relatively well-known process."

"Most fires in natural ecosystems around the world are controlled burns, so we should see this as an opportunity," he adds in a statement. Humans are manipulating processes, so we can figure out how to maximize them.

Severe fires cause erosion and carbon leaching when they burn plant matter and soil organic layers. It can take years or even decades for the carbon lost from the soil to build up again. According to researchers, fires can cause other changes in the soil that can compensate for the loss of carbon in the atmosphere.

Fire strengthens soil carbon in several ways. It creates charcoal, which is resistant to decomposition, and forms "aggregates" that are physical clumps of soil that can protect the carbon-rich organic matter at the core. The amount of carbon bound to soil minerals can be increased by fire.

When the fire intensity is right, ecological systems can store enormous amounts of carbon.

In densely populated forests, when fires are too frequent or too intense, they burn all the dead plant material that would otherwise break down and release carbon into the soil. High-intensity fires can damage the soil, stripping carbon-based organic matter from minerals and killing soil bacteria and fungi.
