The world is losing forests to fire at an unsustainable rate, experts have warned. …in recent decades [wildfire] scale, frequency and intensity in carbon-rich forests have surged. Research from the World Resources Institute (WRI) shows that fires now destroy more than twice as much tree cover as they did two decades ago. In 2024 alone, 135,000km² of forest burned – the most extreme wildfire year on record. Yet fires in other landscapes have not risen in the same way, according to research from the University of Tasmania. While the total area burned globally has fallen for decades as farms have expanded across Africa and slowed the spread of blazes – forests have become a new hotspot. …Four of the five worst years on record have occurred since 2020. Research from the WRI shows that 2024 was the first time that major fires raged across tropical, hot and humid forests such as the Amazon, and boreal forests, such as those spanning Canada’s vast coniferous regions.
