The Amazon has been burning for over two weeks. Wildfires raging in the Amazon rainforest—the world’s largest—have hit a record number this year. According to Brazil’s space research centre INPE, there have already been over 73,000 fires this year, an 83% increase from the number of fires last year. As the largest rainforest in the world, the Amazon is a vital carbon source that helps slow down the pace of global warming. The increase in wildfires has led to the state of Amazonas declaring an emergency.
What’s going on?
Between 11-13 August, several fires were detected over the regions of Rondônia, Amazonas, Pará and Mato Grosso in Brazil. Last week, INPE declared more than 9,000 new fires, seen mostly in the Amazon Basin. The smoke from the wildfires have so intensified that it can be spotted from space. INPE is using satellite images to track the extent of the wildfires. On 19 and 20 August, smoke from these fires caused a complete blackout at 3pm in the city of Sao Paulo, nearly 1,700 miles away.
According to the Global Fire Emissions Database it can be noted that though current fire levels are slightly below average compared to the last 15 years, they are higher in some states like the Amazonas.
Is this normal?
For most of the year, fires in the Amazon are rare events, however in the drier months of July and August, farmers set their plots and pastures on fire to clear the land. Wildfires in the Amazon are not natural events and are usually the result of human activities and droughts that are caused by a combination of climate change and deforestation. The mixture of these fires and droughts ultimately lead to a decrease in the humidity of the forest, making it more susceptible to the spreading of fires.
