Olive trees burn during a wildfire in Greece.

Olive trees burn during a wildfire in Greece. A several hundred year old olive tree burns from inside and that is why it is extremely hard for firefighters to control and extinguish the fire in olive trees fields.
When trees die by fire, they release into the atmosphere the carbon stored within them. This is why the effect of wildfires on emissions is among the most feared climate feedback loops of the world's forests, which have typically been carbon sinks, would become carbon sources, unleashing all that stored gas. Rising temperatures evaporate moisture from the ground, drying out the soil, and making vegetation more flammable.
