Using satellite imagery, NASA has created a time-lapse video depicting the clouds of carbon monoxide produced by the Amazon rainforest fires this month.
The video shows the movement of carbon monoxide in South America during the month of August, showing a dramatic increase over Brazil and the surrounding areas.
Carbon monoxide is known to worsen the effects of climate change by increasing greenhouse gases like methane and carbon dioxide, according to Earther.
The data shows that the carbon monoxide created by the fires has reached elevations of 18,000 feet and encroached on Sao Paolo, which is home to more than 12 million people. Experts have raised concerns about air quality and urban smog as a result of the smoke from the fire.
Last week, residents of Sao Paolo experienced a near-blackout of the sun around midday as a result of the fires. The smoke had to travel nearly 1,900 miles to create the blackout, which lasted about an hour, according to Euro News.
