The 2025 wildfire season had severe human, economic, and environmental consequences.

Globally, the financial toll was unprecedented, with insured wildfire losses reaching record levels. The study warns that without decisive action, societies will face escalating risks as climate change intensifies fire weather conditions. Vulnerable populations near wildland-urban interfaces are particularly at risk, and the strain on firefighting resources could worsen as simultaneous emergencies become more common.
