By 2019 it was a very bosbrandjaar. In a lot of different places, some were raging fires, and as a result, a large amount of greenhouse gas emissions.
“By 2019 was made in the fires of an exceptional year,” says Guido van der Werf, a professor at the Vrije Universiteit amsterdam and is specialized in forest fires, and climate change. “Forest fires are unpredictable and there is a region with a relatively large burn. But in 2019, was particularly interesting because there are a lot of different places, including Russia, india, Indonesia, and Australia, and more burning than usual.”
Forest fires in South America, was also worrying, but not a record
The forest fires in the Amazon region of South America seem to be in 2019, most of the media attention they had received. But if you look at the last twenty years of watching, it appeared that the number of forest fires in South America last year, in fact, not very large.
Van der Werf explained that this is because it is in between 2000 and 2005, in the field, there was a lot of deforestation, so there is a lot of bush fires have emerged. “After that, the deforestation, and increase the number of forest fires has decreased. What is also worrying is that in 2019, just more of it, and deforestation appears to have taken place.”

The number of savannebranden to take
Worldwide, the number of fires in 2019 is not very large. According to the data of the globalfiredata.org it was the number of fires as last year, is below the average of the last sixteen years of age. This is because there is a lot of forest fires were of relatively low savannebranden.
Van der Werf explained that in a large proportion of the year registered by fires raging in the graslandschappen, as in the world. “It is natural that, in periods of drought in these areas, natural fires are proliferating. But, due to the expansion of agricultural areas, and there are fewer of savannah, and there are a lot of less-savannebranden.”

The higher the CO2 emissions due to forest fires
In 2019, from around the world are, however, more greenhouse gases are emitted due to burning. Since 1998, the world has not previously so much of this greenhouse gas released by burning it. This was, according to van der Werf, mainly because of heavy veenbranden in Indonesia and thailand. “In the veenbranden to burn it on a per-square-meter quite a lot of biomass, because you are going to the depths below. As a result, there is a lot of greenhouse gases into the atmosphere,” said the professor.
“The amount of CO2 generated each year from forest fires emissions, which is equal to one-fifth of the annual reduction in co 2 emissions caused by burning fossil fuels such as oil and coal. But, keep in mind that natural fires be aware, however, that if the nature and the forests are recovering, there will be CO2 in the air is taken in. If nature fails to recover, there will be a net amount of CO2 in the atmosphere is in this area.”
Deforestation for agriculture is a major cause of the forest after a fire will not be coming back. Estimated by ontbossingsbranden every year, more CO2 in the atmosphere is 5% of what is annually produced by the use of fossil fuels.
“There is also a fear that due to climate change in forests, for example, in Australia it does not fully recover, resulting in the emission of CO2 in the atmosphere will remain.”
iculate matter can be to make sure that the region is a bit cooler
In addition to greenhouse gas emissions during a fire are also a lot of fine dust in the air. Van der Werf explained that the fine dust would cause that, for a short time regionally, it has one is because of particulate radiation emitted from the sun from entering.
“But the fine dust does not remain a long time in the air, often within a week, the ground is knocked down. As the CO2 is much longer in the air, and the global effect of the warming of the earth. What is the cooling effect of the aerosols due to forest fires, is precisely in proportion to the warming effect of CO2 by way of emission is still under investigation.”
