slight decline in recent decades noted
Well that's some good news for a change. :smile:
A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts.
Prof. Stefan Doerr and Dr Cristina Santin from Swansea University’s College of Science carried out detailed analysis of global and regional data on fire occurrence, severity and its impacts on society.
Their research, published in Philosophical Transactions of the Royal Society B, looked at charcoal records in sediments and isotope-ratio records in ice cores, to build up a picture of wildfire in the past.
In contrast to what is widely portrayed in the literature and media reports, they found that:
The researchers conclude:

Their research, published in Philosophical Transactions of the Royal Society B, looked at charcoal records in sediments and isotope-ratio records in ice cores, to build up a picture of wildfire in the past.
In contrast to what is widely portrayed in the literature and media reports, they found that:
- global area burned has seen an overall slight decline over past decades, despite some notable regional increases. Currently, around 4% of the global land surface is affected by vegetation fires each year.
- there is increasing evidence that there is less fire in the global landscape today than centuries ago.
- direct fatalities from fire and economic losses also show no clear trends over the past three decades.
The researchers conclude:
“The data available to date do not support a general increase in area burned or in fire severity for many regions of the world. Indeed there is increasing evidence that there is overall less fire in the landscape today than there has been centuries ago, although the magnitude of this reduction still needs to be examined in more detail.”
Notwithstanding the serious impacts on society that emerge when fires occur close to populated areas, as exemplified so dramatically by the un-seasonally early wildfires in Canada this spring that led to the successful evacuation of an entire town of 80,000 inhabitants, the researchers find that the risk of direct death from fire for the population as a whole is relatively low compared with other natural hazards.
