Last month, wildfires broke out throughout Turkiye, Greece, Cyprus and Bulgaria. Fires continue in Portugal, France and Spain. In Canada, the blazes have not stopped since April.Satellite data show that fires burn on average about 4 million square kilometres (1.5 million square miles) of the planet’s surface each year, including forests. And the number of wildfires is expected to increase by 50 percent by the end of the century.There are two main reasons for the rise in wildfires.First, the changing climate is driving protracted and frequent heatwaves and droughts that dry out forests, providing an immediate source of tinder and fuel. In a self-perpetuating cycle, wildfires themselves then billow carbon dioxide into the atmosphere, contributing further to the climate crisis. Fires emitted an estimated 6,199 megatonnes of carbon dioxide globally in 2024.Second, the way we live and use land today means we are increasingly encroaching on forests and elevating the risk of wildfires. Many of these fires are started by humans for different reasons – such as carelessness and clearing …
