Forest fires were the source of 25% of the carbon dioxide released into the atmosphere in 2021. This has been reported by the University of California at Irvine.
In the last few decades, scientists have concluded that the climate is getting warmer and warmer due to human activities. This is primarily due to the effects of carbon dioxide, which creates a greenhouse effect. As the main measure to combat this, scientists, activists and politicians recommend reducing emissions from industry. But emissions of this gas are not only produced by humans, but also by natural events such as volcanic eruptions and forest fires.
Stephen Davis and his colleagues conducted a study and found that in 2021, a record was set in the observation history for carbon dioxide emissions from forest fires. Such results were obtained by analyzing data from climate satellites that allowed the CO concentration to be measured.2such as when monitoring the state of forests in temperate and tropical regions.
Scientists compared the volume of CO emissions2 with the area of burned areas of forests that allows them to determine the amount of carbon dioxide produced by these natural disasters each year. Calculations have shown that forest fires have emitted an average of 10% of total CO2 over the past 20 years.2enters the earth’s atmosphere.
The biggest exception to this rule was 2021, when wildfires in temperate latitudes released more than 1.72 billion tons of carbon dioxide into the atmosphere. As the researchers point out, this means that when fires in other climate zones are taken into account, wildfires in 2021 accounted for about 25% of total CO2 emissions.2 for this year, this is an absolute record for the entire observation period.
At the same time, climatologists expect this record to be updated in the coming years due to deteriorating forest health and climate change.
