The increase in wildfires raises the temperature of the Earth's surface

More frequent and severe wildfires increase the temperature of the exposed land surface one year after the fire, according to an analysis of forest satellite data collected from 2003 to 2016. In recent decades, large wildfires have doubled or tripled their average size in eastern Spain, Canada, and western United States, as noted in the research published in Nature. The authors call for consideration of these effects on surface temperature when managing forests.

How Wildfires and Saharan Dust Affect Hospitalizations for Psychological Disorders

A team led by the Carlos III Health Institute has analyzed how short-term concentrations of particles associated with wildfires and Saharan dust incursions influence hospital admissions in Spain due to mental and behavioral disorders. The results were explained in a briefing organized by the Science Media Centre Spain.

Short-term exposure to ozone from wildfires is associated with increased mortality

Wildfires increase the level of tropospheric ozone. An international study, published in The Lancet Planetary Health and involving Spanish participation, suggests that one- to three-day exposure to wildfire-related ozone pollution is linked to increased daily all-cause and respiratory mortality rates. The study analysed more than 700 locations - including in Spain - between 2000 and 2016, calculated the daily concentration of wildfire-related ozone pollution and compared it with data on daily deaths in the areas studied.

Reactions: the wildfire in Tenerife forces thousands of people to evacuate although they manage to stabilize it in some points

The fire that originated on August 15 between the Tenerife municipalities of Arafo and Candelaria, in the northeast of the island, is advancing on several fronts and has affected more than 13,000 hectares, although the firefighting services have stabilized it in some points. The people evacuated in the last days have been thousands. As confirmed by the president of the Canary Islands, Fernando Clavijo, the fire has been caused.

Sixth-generation wildfires: what they are, how climate change affects them and ways to prevent them

Rising temperatures, droughts, heat waves and abundant untreated material in forests are the perfect cocktail for fires to break out. When they are beyond the control of firefighting services - because of their intensity, speed and unpredictability - we speak of mega-fires or sixth generation wildfires, a phenomenon that is not new but whose frequency could increase due to rural abandonment and climate change. Some experts have thus described the fire in Tenerife that began on August 15 and has forced the evacuation or confinement of thousands of people.

How to prevent large forest fires in a context of climate change

The fires in Hawaii, which have left at least a hundred dead and hundreds missing, have devastated entire towns and villages and have put the issue of how to prevent such intense fires back on the table. World Wildfire Prevention Day is celebrated this Friday 18 August. The increase in the occurrence and recurrence of large wildfires jeopardizes the resilience of socio-ecological systems. Efforts in prevention must be a priority and constant throughout the year. We have a joint responsibility as a society to face this unprecedented problem, which will worsen in the coming years.

The territorial model and forest fires: a change in vision is needed

We are finding fires that exceed the maximum extinguishing capacity of the resources that are being asked to control them by 4 or 5 times, which is nonsense, as well as recklessness. We should ask ourselves about our territorial, social and economic model for dealing with this situation so that we do not leave the fire-fighting services with this intractable and unsolvable problem.
