If you have turned on a TV or read the news during the past few months, you have probably heard of the widespread fires that wrought havoc on the Amazon rainforest this year. Fires occur in the rainforest every year, but the past 11 months saw the number of fires increase by more than 70% when compared with 2018, indicating a major acceleration in land clearing by the country’s logging and farming industries.
The smoke from the fires rose high into the atmosphere and could be seen from space. Some regions of Brazil became covered in thick smoke that closed airports and darkened city skies.
As the rainforest burns, it releases enormous amounts of carbon dioxide, carbon monoxide, and larger particles of so-called “black carbon” (smoke and soot). The phrase “enormous amounts” hardly does the numbers justice – in any given year, the burning of forests and grasslands in South America emits a whopping 800,000 tonnes of black carbon into the atmosphere.
