Humans burn plant matter for many reasons; clearing forests for agricultural land, slash-and-burn agriculture, ritual savannah burning, wildfires. Recent research by Professor Mark Jacobson at Standford University suggests that burning living matter may contribute far more to climate change than previously thought. This is because, unlike other types of emissions, burning plant matter releases carbon particles into the atmosphere which accelerate warming. These particles are also very damaging to human health, and are responsible for the deaths of 250,000 people every year.
Each year, humans pump nearly 40 billion tons of carbon dioxide into the atmosphere. We are now certain that these emissions, along with other greenhouse gases, are altering our climate and warming the planet. One major source of carbon dioxide emissions is burning plant matter, either deliberately or because of wildfires. But the contribution of fires to climate change has not previously been quantified.
