5 Graphics Explain the Climate-Fire Feedback Loop

Forest fires have become a harsh new reality for millions globally, with their impacts felt near and far. Over the last few years, fires have destroyed billions of dollars in property, displaced thousands of people and coated cities in choking smoke, causing deadly air quality.

It's no coincidence that fires are becoming more intense as the planet warms. Fires need hot, dry conditions to ignite and spread. While fire is a natural part of some forest ecosystems, climate change is making forest fires worse, and vice-versa — creating a vicious "climate-fire feedback loop."

It works like this: Rising greenhouse gas (GHG) emissions lead to hotter, drier conditions. This makes it easier for fires to spark and grow. Worsening fires release larger amounts of stored carbon into the atmosphere as trees and plants burn — further accelerating climate change and perpetuating the cycle.
