Wildfires can affect climate and weather and have major impacts on atmospheric pollution.[94] Wildfire emissions contain fine particulate matter which can cause cardiovascular and respiratory problems.[95] Forest fires in Indonesia in 1997 were estimated to have released between 0.81 and 2.57 gigatonnes (0.89 and 2.83 billion short tons) of CO2 into the atmosphere, which is between 13%?40% of the annual carbon dioxide emissions from burning fossil fuels.
