Summer is not only the season of good weather, but it is also the period in which the greatest number of fires occur during the year, at least in Italy and in other nations bordering the Mediterranean.
However, there is a surprising fact that agitates environmentalists and which is shared by other nations of the world. In the last decades, the frequency and destructiveness of fires it has more than doubled compared to the fires that occurred even just forty years ago.
The reasons why this is happening are linked to anthropogenic pollution and global warming. High temperatures they favor the spread of flames, such as the ignition of tow in the fields and woods thanks to the action of arsonists.
To monitor the number of fires around the world, some researchers fromUniversity of Tasmania they used satellite recordings belonging to this millennium, following the evolution of beyond step by step 3,000 historic fires that have devastated the planet.
This work was then used to carry out a study published in the journal Nature Ecology and Evolutionwhich has spread alarm among environmentalists and the scientific community.
“I expected to see some increase, but the rate of growth in the number of fires impressed me” said the study’s lead author, Calum Cunningham. Scientists also found that the last six years have been the most extreme ever, when looking at the intensity and frequency of wildfires.
The most terrible year, however, was the one that just passed, 2023. During last summer, The Northern Hemisphere has been hit hard by the flames, which have destroyed hectares of forest, entire communities in Europe and Canada, and many tourist locations across the Mediterranean, including Sicily (we remember the fires that devastated the countryside around the capital) and Calabria, also affected by hundreds of fires a day.
Scientists also reiterate that only a small percentage of fires start naturally. The majority is in fact caused by man, in many cases voluntarily.
