The Amazon fires are bad enough. Let's talk about the harmful carbon monoxide
A pollutant that can travel large distances, carbon monoxide can persist in the atmosphere for about a month. At the high altitude mapped in these images, the gas has little effect on the air we breathe; however, strong winds can carry it downward to where it can significantly impact air quality. Carbon monoxide plays a role in both air pollution and climate change. The graphic below shows global concentrations of upper level carbon monoxide during the month of September 2015.
Carbon monoxide across the globe during the month of September 2015. Red areas are higher concentrations. Gray shows missing data.Carbon monoxide, unlike carbon dioxide or methane, does not have as direct of an effect on global temperatures. However, it can be problematic in its own way. When combined with other pollutants and sunlight, it helps to cook up a harmful"stew" of photochemical smog , particularly in urban areas where carbon monoxide values can be high.
